The Thunderbolt Certified 16-in-1 Quad docking station from Plugable delivers peak performance. The innovation starts with our display connections. Connect your 4K screens through 2x HDMI ports and 2x DisplayPort ports — a rare level of display flexibility in a Thunderbolt dock. But the real expansion picks up at the ports. Offering sixteen total ports to park your peripherals, including 7x USB ports, SD and microSD card readers, Audio, and 2.5Gbps Ethernet. It even adapts to your desk with an included stand for vertical or horizontal orientation options.
Quad Display
With this Thunderbolt 4 docking station Windows computers can use the 2x HDMI ports, and 2x DisplayPort ports to connect as many as 4x screens at up to 4K 60Hz. Can also be used a single, dual, or triple display docking station.
On Mac (Intel, M1 / M2 / M3 Pro/Max, M4/Pro/Max CPU), extend your desktop to 2x screens using any combination of HDMI and/or DisplayPort. Macs with an M1 / M2 / M3 (base model, non-Pro/Max) CPUs only support one external display.
Please see the full display output capabilities article here for more information.
Note: The USB-C port on the back of the dock supports data transfer only (no video output for USB-C/Thunderbolt displays).
Charge Up with 100W Power Delivery
The laptop Thunderbolt docking station offers USB Power Delivery up to 100W (98W certified) — no more climbing under the desk to get plugged in.
Not all laptop docking stations handle power the same. With the TBT4-UDZ, if your laptop needs less power, the docking station adjusts and only sends the optimal wattage.
And with 6x available USB ports, and one USB-C port, your devices will always have a place to connect.
16 Ports to Power Productivity

- Multi-display capabilities will vary depending on host system graphics card support, up to 2x 4K 60Hz displays
- MAC: 12" MacBook Retina (non Air/Pro) models are limited to a single 4K 30Hz extended display
- LINUX: Not supported
- CHROME OS: Not supported
Please see the full display output capabilities article here for more information.
重要な注意事項
- Apple M1 / M2 / M3 (base model, non Pro/Max) based MacBook, Mac Mini, and iMac systems (non-Intel processors) only support a single external display via Thunderbolt/USB4 ports (this is a limitation of the M1 / M2 / M3 base model graphics chipset, M1 / M2 / M3 Pro/Max and M4/Pro/Max support dual displays)
- Most Thunderbolt 4 Windows laptop systems will require the internal display to be "disconnected" in the Windows Display Settings to enable four external extended displays. (support is dependent upon the system graphics chipset configuration)
- Windows 10 and Windows 11 systems will try to mirror/clone attached displays by default upon first connect, it will be required to separate any mirrored/cloned displays and change them to be extended in the Windows Display Settings. For a quad display setup on a Thunderbolt 4 host this step may need to be repeated until all displays are extended
- Some Thunderbolt 3 Windows systems will not support dual displays (only one DisplayPort stream). Please check with your system manufacturer to verify dual displays via Thunderbolt 3 are supported. A common example would be Intel NUC hosts which usually only support a single display through Thunderbolt 3
- USB-C ポートを搭載しているすべてのシステムが、USB-C ポートからの充電に対応しているわけではありません。例えば、100W 以上のワット数を必要とするワークステーションやゲーミングノート PC は USB-C ポートからの PD 充電に対応していないことがあります。その場合はノートパソコンに付属してきた別の電源アダプタを接続する必要があります。PC システムが PD 充電規格に対応しているかどうかを確認するには、システムの製造元にお問い合わせください。
- Dock capabilities are reduced when connected to USB-C only systems. When using the dock in USB-C mode (no Thunderbolt support from system) the 10Gbps USB-C and USB-A ports will be limited to 5Gbps operation. Display support may also be limited to a maximum of two 1080p @ 60Hz displays (dependent upon system graphics card DisplayPort implementation)
- Windows systems may require updated Thunderbolt drivers, Thunderbolt NVM firmware, system UEFI BIOS, and graphics card drivers from the system manufacturer (Apple systems provide this automatically)

USB Port Types
USB-A
pietz, CC BY-SA 3.0 , via Wikimedia Commons
This is the standard USB connection that most computers offered prior to the introduction of USB Type-C (USB-C). Even after the introduction of USB Type-C, this is still quite common.
It can provide data transfer rates up to the USB 3.1 Gen 2 (10 gbps) specification depending on the host and device, but does not directly support video in the way that USB-C Alternate Mode does. This limitation makes DisplayLink USB graphics adapters and docking stations ideal on systems that do not have USB-C, or in instances where more displays are needed beyond available video outputs of a PC.
USB-B

IngenieroLoco, CC BY-SA 4.0, via Wikimedia Commons
This type of connection comes in a couple different styles depending on whether USB 3.0 and higher transfer rates are supported (bottom graphic). Usually this type of connection is used to plug into USB devices that do not have a fixed cable connected, such as USB docking stations, USB hubs, printers, and others.
USB Mini-B
Fred the Oyster, CC BY-SA 4.0 , via Wikimedia Commons
One of the first connectors for charging a smartphone, wireless game controller (such as the Sixaxis and DualShock 3), and other small devices such as external hard drives. Not commonly used today, but is still used in some cases. Most devices using USB Mini B are using USB 2.0, though a USB 3.0 variant does exist. This specification also added USB On-The-Go (OTG) functionality, though it is more commonly implemented with Micro USB.
USB Micro-B
Fred the Oyster, CC BY-SA 4.0, via Wikimedia Commons
IngenieroLoco, CC BY-SA 4.0 , via Wikimedia Commons
A smaller connector that serves many of the same uses as the Mini B connector, with added optional features such as Mobile High-Definition Link (MHL) to allow devices like smartphones to output video to larger displays without requiring a dedicated port for video output.
The larger variant of USB-B is most commonly used for external hard drives for higher 5Gbps transfer rates.
USB-C, Thunderbolt™ 3, and Thunderbolt™ 4
Niridya , CC0, via Wikimedia Commons
The most recent USB connection, USB Type-C (USB-C), represents a major change in what USB can do. The connector is smaller, can be connected in two orientations, is able to carry substantially more power and data, and can directly carry video signals of multiple types (HDMI, DisplayPort, etc.) Intel has also adapted the USB-C connector for use with Thunderbolt 3 and Thunderbolt 4.
It is important to note that while all Thunderbolt 3 and Thunderbolt 4 connections are USB-C, not all USB-C connections can be used with Thunderbolt 3 or Thunderbolt 4 devices.

Can I Connect a DisplayPort (DP) Monitor to the HDMI Port on This Device Using an Adapter or Cable?
No. Most DisplayPort to HDMI cables and adapters are one-way adapters from a DisplayPort Source (computer or docking station) to a HDMI Sink (television, computer monitor, or projector). These cables do not work in reverse.
DisplayPort uses packet-based data transmission, breaking the video stream into individual packets of data allows for longer cable runs, use in both copper and fiber-optic cables, and allows for higher bandwidth than other video formats. It is relatively easy to convert from DisplayPort to HDMI (computers with HDMI output ports already do this internally) and dual-mode DisplayPort outputs have built-in adapters to output a HDMI signal for use with passive DisplayPort to HDMI adapters.
HDMI uses a video signal, similar to DVI, this requires more power to operate at the same cable lengths as DisplayPort and requires significantly more processing power to create DisplayPort packet-based data.
Externally powered HDMI to DisplayPort adapters do exist, these generally have a USB or small barrel plug for power, and can convert from a HDMI Source to DisplayPort Sink. In most cases they have reduced resolution or refresh rates compared to modern signal sources and can introduce delay in the data connection between the display and computer potentially causing reduced connectivity or display performance problems.
We do not currently recommend using HDMI to DisplayPort adapter with our docking stations. In our testing they have been unreliable compared to a native DisplayPort connection. Many of our newer docking stations include both HDMI and DisplayPort outputs to reduce the need for additional adapters or adapter cables.
Understanding and Troubleshooting Network Performance
Computer networking is a complex topic. In this article, we'll be taking a deep dive on the nuances of network performance for those who need some additional explanation while striving to be concise, and to educate users of various experience levels relating computer hardware and computer networking.
If you just need to know how to perform a network performance test/benchmark, jump down to configuring iPerf.
Core Network Concepts
LAN vs WAN
With regards to network performance, it is crucial to first separate whether an issue is with Wide Area Network (WAN) performance, or if the issue is with Local Area Network (LAN) performance.
Your LAN is essentially the network inside your home or business. Many homes use a combination modem/router device provided by their Internet Service Provider (ISP). In some cases, especially in businesses, you may have a separate modem and router, along with other equipment connecting to the router such as a network switch.
Your modem, and the connection it establishes to your ISP—whether through coaxial cable, fiber, phone lines, or long-range wireless—essentially marks the point between the WAN and the LAN. The connection your modem makes to your ISP is the WAN, and any devices you connect through your router behind that modem belong to the LAN.
Link Rate
Almost every type of connection your computer makes to any piece of hardware will have a link rate of some kind. The link rate establishes how fast data can possibly be transferred across any given connection, but it does not guarantee how fast the hardware on either end of the connection will actually transfer data.
The concept of link rates, and their related bottlenecks, is likely best conveyed by giving an example of what connections might be involved in transferring a file from one computer on your LAN to another.
- 800Mbps—The file source is a USB 3.0 thumb drive capable of 100MB/s (800Mbps) read/write.
- 480Mbps—The USB 3.0 thumb drive is plugged into a USB 2.0 port on the PC, which has a maximum throughput of 480Mbps
- 1000Mbps—PC1's Ethernet connection establishes 1Gbps (1000Mbps) link to the router via Ethernet
- 300Mbps—The router connects to a second PC (we'll refer to this as PC2) via Wi-Fi, and it has established a 300Mbps link to the Wi-Fi adapter on PC2
- 480Mbps—The Wi-Fi adapter on PC2 is connected via a USB 2.0 port. The link rate of the USB connection to PC2 is at 480Mbps
- 6000Mbps—PC2 is going to store the file on an internal hard drive with a link rate of 6Gbps
- 1600Mbps—File Destination: SATA hard drive capable of 200MB/s (1600Mbps) read/write.
Following this chain, we see that 300Mbps is the slowest link rate established. This means that, regardless of the link rates established elsewhere, the absolute maximum the data can possibly be transferred is 300Mbps.
if we were to change the Wi-Fi connection to a wired Ethernet connection capable of 1Gbps, our performance bottleneck would then become the USB 2.0 connection to the USB drive where the file is stored.
Ports and Interfaces
Interfaces
A network interface represents connections, whether wired or wireless, that are made to form a network between devices.
Ports
Some may refer to physical hardware connections as "ports". For the purposes of networking, ports are logical constructs that can also be referred to as "network ports". Each network interface has 65,535 of these logical ports. Each port on a network interface is a separate data connection.
Benchmarking Network Adapter Performance
To properly benchmark network adapter performance, we need to:
- Use a simple LAN configuration
- Eliminate bottlenecks, especially link rate bottlenecks
Websites like speedtest.net, fast.com, and other performance tools in your web browser are going to use your WAN connection, and are not appropriate for determining if a network adapter is working well.
Transferring files from one computer to another on your LAN is typically not the best way to benchmark a network adapter. File transfers are bottlenecked by a number of things, including performance limitations of the disk the data is on, and often times a lack of establishing parallel network connections to perform the task.
One of the most accurate ways to benchmark network performance on a LAN is by using iPerf . To more effectively benchmark network adapter performance, it is best to establish a point-to-point connection between two PCs, rather than connecting through a router or switch.
Configuring iPerf
To test a connection using iPerf, you'll need at least two network interfaces, and preferably two computers. You'll also need to know the IP (Internet Protocol) address assigned to each network interface . One network interface will function as an iPerf server, and the other network interface will function as an iPerf client. Lastly, you'll need to download the version of iPerf 3.x that's appropriate for your computer's operating system and extract/install it .
Windows
- Make sure the drivers for both network interfaces involved in the test are using up-to-date drivers. Drivers for Plugable products can be found here.
- Download and extract iPerf for Windows
- Open Command Prompt
- Press Windows Key + R or + R, then enter
cmdin the window that appears - Search the Start Menu for
Command Prompt, and open it
- Press Windows Key + R or + R, then enter
- Navigate Command Prompt to the directory the directory where iPerf is located
- The
cdcommand is for 'change directory'- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
cd %USERPROFILE%\Desktop\iperf
- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
- The
- Run iperf in server mode via Command Prompt
iperf3.exe -s
macOS
- Usually it is best to install iperf on macOS using brew in Terminal
- Make sure the drivers for both network interfaces involved in the test are using up-to-date drivers
- Open Terminal
- Run iPerf in server mode
iperf3 -s
Linux
- Usually it is best to install iperf using the package manager in your Linux distro. For example, in Ubuntu, use
apt: sudo apt install iperf3
- Make sure the drivers for both network interfaces involved in the test are using up-to-date Drivers
- Open Terminal
- Run iPerf in server mode
iperf3 -s
Next, you'll need to run iPerf in client mode, targeting the IP address of the server/interface where iPerf is running in server mode. Additionally, we'll run the test for 30 seconds using -t 30 and with four parallel connections using -P 4. Running 4 parallel connections is optimal for saturating a network link.
Windows
- Open Command Prompt
- Press Windows Key + R or + R, then enter
cmdin the window that appears - Search the Start Menu for
Command Prompt, and open it
- Press Windows Key + R or + R, then enter
- Navigate Command Prompt to the directory the directory where iPerf is located
- The
cdcommand is for 'change directory'- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
cd %USERPROFILE%\Desktop\iperf
- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
- The
- Run iperf in client mode via Command Prompt (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3.exe -c 192.168.0.200 -t 30 -P 4
macOS / Linux
- Open Terminal
- Run iPerf in client mode (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3 -c 192.168.0.200 -t 30 -P 4
iPerf should start performing a network performance test. If the test fails to start, make sure that iPerf is not being blocked by your PC's/Mac's firewall.
Why iPerf is Ideal for Benchmarking
Unlike a file transfer, iPerf runs in memory on the PC and generates data to send using the CPU directly. This alleviates potential bottlenecks generated by storage devices, and allows you to explicitly control how many parallel connections are being used to transfer data rather than being unsure if parallel network connections are being used by other means.
Conclusion
There's a lot more to networking that isn't covered in this article, but we hope this helps explain enough to get an accurate measure of your network performance.

My Docking Station/Adapter Works Well With My Windows Laptop, but When I Close the Lid the Displays and Laptop Turn Off or Sleep. How Do I Fix This?
Most Windows notebook computers power management settings will default to putting the computer to sleep with the lid closed, regardless of any external displays, keyboard, or mouse connected to the computer. If this is happening but you would prefer the system to remain active with the lid closed utilizing the external display or displays, these settings can be changed by performing the following:
For Windows 10:
- Start by right-clicking on the Start button and select Power Options from the menu.
- From the right side of the Power Options settings page, select the blue link for Additional power settings
- From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
- Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing
- Click the Save Changes button and restart the system (making sure that the laptop’s power adapter is also connected) and test the behavior again.
For Windows 11:
- Start by right-clicking on the Start button and select Power Options from the menu.
- In the upper left corner of the settings window, in the search box, type "lid" then select Change what closing the lid does from the search results
- Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing
- Click the Save Changes button to apply the new settings.
Closing the lid should no longer put the computer into sleep mode when an external display and power source is connected, instead one of the external displays should now become the Primary display with the desktop icons instead of the laptop's built-in display.
The lid may still need to be opened to perform the following tasks:
- To power on the computer from a fully powered off state
- To log into the computer if logged out or if the computer is restarted with the lid closed
- To wake the computer from a deep sleep state ( hibernation, or Windows hybrid sleep states )
My Windows Laptop Will Not Boot Properly When My Docking Station Is Connected
If your Windows laptop will not boot properly when a docking station is connected to the laptop, most often the cause is an external device connected to the docking station (for example an external USB storage drive) as opposed to the dock itself.
If you are affected by this condition, please follow these steps in order to isolate the behavior further:
- Disconnect all USB devices from the docking station and put them aside for the moment.
- Disconnect any displays connected to the dock's video outputs.
- Disconnect any audio devices connected to the dock's audio ports (if present).
- Disconnect the Ethernet network cable from the dock's Ethernet port (if present).
- The only remaining connections should be the dock's power adapter cable and the USB cable used to connect it to the laptop. No other external devices should be connected to the dock.
- While in this state, reboot the laptop to test the behavior.
- Assuming the laptop boots as expected, please reconnect each device back to the dock one at a time and reboot after each one to test the behavior again. Please reconnect the displays first, then the audio devices, then the Ethernet cable. Please reconnect any USB devices to the dock last, again rebooting after each one is added to test the behavior.
In our experience helping others, the most common cause of this behavior is an external USB storage drive connected to one of the dock's USB ports. In some cases, a laptop may try to boot from an external storage drive by mistake as opposed to the laptop's built-in storage drive. Since most external USB storage drives are not 'bootable', this can interrupt the boot process.
If this behavior occurs, the most common way to mitigate the behavior is to access the laptop's System BIOS (also known as UEFI firmware) to change the 'boot order' settings to ensure that the laptop's internal storage drive is the first boot option. Doing so helps ensure that the laptop will not try to boot from an external USB storage device.
Every laptop system is different, so the best resource for accessing the System BIOS and changing the settings is the manual for the laptop provided by the laptop manufacturer.
Network Adapter Prioritization on Windows
There are various reasons and configurations that can benefit from having more than one network adapter present on a PC.
For users with newer networking products, featuring 2.5Gbps link rates or greater, it may be beneficial to prioritize that network connection over others on your PC that are still connected to your network/LAN.
Can I Use a Thunderbolt 4 Cable to Connect to a Thunderbolt or USB-C Device Such as a Phone, iPad, or Docking Stations?
Yes, this Thunderbolt 4 cable is compatible with any USB-C port for data transfer, charging, or video (capabilities will depend on peripheral used).
Do Thunderbolt 4 Cables Support USB-C Power Delivery for Host Charging?
Yes, Thunderbolt 4 cables can support up to 240W of power allowing you to keep your devices charged, but some cables may not offer the full 240W capability and instead offer a maximum of 100W of Power Delivery.
Are Thunderbolt 4 Cables Compatible With Thunderbolt 3 Computers and Devices?
Yes, Thunderbolt 4 cables are backward compatible with Thunderbolt 3 and USB-C devices.

My Plugable Dock Is Missing a Component Such As the Power Supply, USB Cable, or Other Adapter.
If your package is missing one or more of the items that should be included with your Plugable dock (included items are listed on a chart on the side of the box), start by double checking if the part is still in the packaging. Pieces can occasionally get stuck in the corners under the main insert in the box.
If you are still unable to locate the piece, please contact support@plugable.com with the following information:
1. Amazon Order ID (or other proof of purchase) associated with your Plugable device.
2. A description of the parts that are missing from your order.
3. Your preferred shipping address (and a phone number associated with that address).
4. The serial number of your Plugable Dock.
Can I Connect My High Refresh Rate Monitor (e.g. 120Hz, 144Hz) to a Plugable Dock?
Most Plugable docks do not officially support monitors over 60Hz including 120Hz or 144Hz refresh rate unless otherwise specified on the Plugable product page or listing.
DisplayLink USB Graphics technology and Silicon Motion based docking stations and graphics adapters, like our USB 3.0 dual display and USB Type-C triple display docking stations, are limited to 60Hz fresh rate by the USB graphics controller hardware.
USB Type-C DisplayPort Alternate Mode docking station and ports on our USB Type-C Triple Display Docking Stations can support higher refresh rates, but may be limited by the computer's capability and available bandwidth to the docking station. Additionally, when paired with DisplayLink or Silicon Motion USB graphics, having displays at different refresh rates may reduce overall system performance. Due to this we normally recommend limiting all connected displays to 60Hz refresh rate when using DisplayLink and Silicon Motion graphics technology with directly connected, or USB Type-C DisplayPort Alternate Mode controlled displays.
Monitors with refresh rates higher then 60Hz may be connected to a docking station operating at up to 60Hz, or connected directly on the computer's HDMI or DisplayPort to ensure the display is powered by the system's native GPU.
Do Plugable products support the Apple SuperDrive?
Unfortunately Plugable products do not support the Apple SuperDrive.
The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here → How to connect the Apple USB SuperDrive
If you have purchased a Plugable product to use with your Apple SuperDrive, and would like some additional assistance please do not hesitate to reach out. You can do so by emailing support@plugable.com, or going to Plugable.com/Support.

What are the display output capabilities for the TBT4-UDZ?
The TBT4-UDZ docking station offers two primary modes to output video to attached displays via the dual HDMI 2.0 and dual DisplayPort 1.2 outputs: Thunderbolt 3/Thunderbolt 4/USB4 mode and USB-C DisplayPort Alternate mode.
Systems with Thunderbolt 3, Thunderbolt 4, and USB4 support and USB-C only systems without Thunderbolt support will have differing capabilities. In addition, some Thunderbolt 3 systems may only support a single display and some USB-C only systems may lack USB-C DisplayPort Alternate Mode video output entirely (no displays will work). Windows versus Mac compatibility varies as well. Due to varying support please see below for more technical details:
Multiple display capabilities for Thunderbolt 4/USB4 systems:
-
Thunderbolt 4/USB4 Windows systems with DisplayPort 1.4 HBR3 DSC (High Bit Rate 3 with Display Stream Compression) can offer up to four extended displays at 4K (3840x2160) at 60Hz via 2x HDMI 2.0 and 2x DisplayPort 1.2 video outputs utilizing DisplayPort MST (Multi-Stream Transport) technology built into the dock. (USB4 system support may vary depending on system manufacturer specifications)
-
Apple M1/M2/M3 Pro and M1/M2/M3 Max based Macs do not support DisplayPort MST (Multi-Stream Transport) technology and thus can support up to 2x 4K (3840x2160) 60Hz extended displays via 2x HDMI 2.0 and 2x DisplayPort 1.2 video outputs which can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Group 1" and "Group 2" output groups. Two displays cannot be connected to the same group.
- Apple M1/M2 based Macs (base model, non-Pro/Max) are limited to a single 4K (3840x2160) 60Hz extended display which can be connected to any single HDMI 2.0 or DisplayPort 1.2 video output on the dock. (M1/M2 users should consider a DisplayLink USB graphics based docking station like our UD-ULTC4K instead which can enable up to three 4K 60Hz displays - the TBT4-UDZ does not use DisplayLink USB graphics technology)
-
MacBook Air and MacBook Pro M3(base) can support up to two displays with the lid closed(clamshell) over Thunderbolt.
- macOS Sonoma 14.3 or later for MacBook Air M3 is required
- macOS Sonoma 14.6 or later for MacBook Pro M3 is required
Multiple display capabilities for Thunderbolt 3 systems:
-
Thunderbolt 3 Windows systems with dual DisplayPort streams can offer up to 2x 4K (3840x2160) 60Hz extended displays via 2x HDMI 2.0 and 2x DisplayPort 1.2 video outputs which can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Group 1" and "Group 2" output groups. Two displays cannot be connected to the same group*. (*A configuration with three displays may technically be able to be connected, however, by doing so there will be severe bandwidth limitations and will lead to suboptimal resolution and refresh rate options for all three displays. As such this configuration is not recommended or supported.)
-
Thunderbolt 3 Windows systems with a single DP stream are limited to a single 4K (3840x2160) 60Hz extended display which can be connected to any single HDMI 2.0 or DisplayPort 1.2 video output on the dock.
-
Thunderbolt 3 Apple Macs with Intel processors can support up to 2x 4K (3840x2160) 60Hz extended displays via 2x HDMI 2.0 and 2x DisplayPort 1.2 video outputs* which can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Group 1" and "Group 2" output groups. Two displays cannot be connected to the same group.
(*Please note: Older Intel based Macs (non Apple M series processors) are advised to use HDMI for the best compatibility with 4K 60Hz displays if possible. The use of DisplayPort is supported for Intel Macs, however the display(s) may be limited to 4K 30Hz maximum. For Intel based Macs our TBT3-UDZ Thunderbolt 3 dock may be a better choice for DisplayPort displays requiring 4K 60Hz)
Multiple display capabilities for USB-C only Windows systems:
(Non-Thunderbolt/USB4, using USB-C DisplayPort Alternate Mode (DP Alt Mode) operating in USB-C Multifunction DisplayPort Mode (MFDP))
-
USB-C DP Alt Mode MFDP Windows systems with DisplayPort 1.4 HBR3 with DSC (High Bit Rate 3 with Display Stream Compression) can offer up to two displays at 4K (3840x2160) at 60Hz via 2x HDMI 2.0 or 2x DisplayPort 1.2 video outputs which can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Group 1" and "Group 2" output groups. Two displays cannot be connected to the same group.
-
USB-C DP Alt Mode MFDP Windows systems with DisplayPort 1.4 HBR3 (High Bit Rate 3) can offer one display up to 4K (3840x2160) at 60Hz or two displays 1440p (2560x1440) at 60Hz via 2x HDMI 2.0 or 2x DisplayPort 1.2 video outputs which can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Group 1" and "Group 2" output groups. Two displays cannot be connected to the same group.
- USB-C DP Alt Mode MFDP Windows systems with DisplayPort 1.2 HBR2 (High Bit Rate 2) can offer a single display up to 4K (3840x2160) at 30Hz or two displays 1080p (1920x1080) at 60Hz via 2x HDMI 2.0 or 2x DisplayPort 1.2 video outputs which can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Group 1" and "Group 2" output groups. Two displays cannot be connected to the same group.
Multiple display capabilities for USB-C only Mac systems:
(Non-Thunderbolt/USB4 using USB-C DisplayPort Alternate Mode)
- USB-C Apple 12" MacBook Retina Macs (single USB-C port, non-Air/Pro) are limited to a single 4K (3840x2160) 30Hz extended display which can be connected to any single HDMI 2.0 or DisplayPort 1.2 video output on the dock.
Important Notes:
- Most Thunderbolt 4 Windows laptop systems will require the internal display to be "disconnected" in the Windows Display Settings to enable four external extended displays. (support is dependent upon the system graphics chipset(s) configuration)
- Windows 10 and Windows 11 systems will try to mirror/clone attached displays by default upon first connect, it will be required to separate any mirrored/cloned displays and change them to be extended in the Windows Display Settings. (for a quad display setup on a Thunderbolt 4 host this step may need to be repeated until all displays are extended)
- Some Thunderbolt 3 Windows systems will not support dual displays (only one DisplayPort stream). Please check with your system manufacturer to verify dual displays via Thunderbolt 3 are supported. (a common example would be the popular Intel NUC hosts which usually only support a single display through Thunderbolt 3)
- For Thunderbolt 4 equipped Windows desktop systems with Intel 11th gen processors ("Rocket Lake-S"). Due to limitations of the integrated Intel UHD 730 and 750 graphics these systems will be limited to a maximum of three displays if the Thunderbolt 4 controller is utilizing the Intel integrated graphics as the DisplayPort video signal source. Additionally, 11th gen processors with an "F" or "KF" designation (like the 11900KF) lack integrated video entirely and will not support any displays over Thunderbolt 4 (again, if the Thunderbolt 4 controller relies on the integrated graphics).
If the Intel 11th Gen Thunderbolt 4 desktop has auxiliary DisplayPort video inputs (either on the motherboard, or via a Thunderbolt 4 add-in card) the user can connect the Thunderbolt 4 controller to a dedicated PCI Express graphics card (such AMD Radeon, Nvidia GeForce, or Intel Arc) DisplayPort video outputs and those systems are capable of supporting four displays (as the integrated UHD graphics is not utilized in this configuration). Typically systems with this ability to "loopback" the video signal from a PCIe graphics card into the Thunderbolt controller are rare except for very high end workstation or gaming class desktops.
- We do not officially support high refresh rate displays above 60Hz. (higher refresh rates under 4K resolution may be selected but performance and stability above 60Hz is not guaranteed)
- We do not support HDR (High Dynamic Range) or adaptive sync/variable refresh rate (such as AMD FreeSync or Nvidia G-Sync technologies)
- If converting the DisplayPort outputs to a different connector type an active DisplayPort adapter is required. Passive DisplayPort adapters are not supported. (the 2x DisplayPorts do not offer DP++ capabilities required for passive adapters)
- Users with legacy DVI displays should use passive HDMI to DVI adapters in most cases* rather than active DP to DVI adapters. (*Dual Link DVI displays will require an active DP to DVI Dual Link adapter)
- Users with legacy VGA displays should use active DisplayPort to VGA adapters (or active HDMI to VGA adapters)
- Thunderbolt 3, Thunderbolt 4, USB4, and USB-C DisplayPort Alternate Mode based USB-C displays are not supported
- Legacy Apple ADC displays are not supported
- 5K, 6K, and 8K displays are not supported as they require a higher resolution output than what this dock can offer
- The use of multiple DisplayPort displays daisy-chained via DP MST (DisplayPort Multi-Stream Transport) is not supported
- Older 4K displays that require DP MST to operate at 4K 60Hz are not supported. (these displays use two 1920x2160 vertical panels in the display via DP MST to achieve 3840x2160)
- Legacy Apple Thunderbolt (1 or 2) systems being converted to Thunderbolt 3 using Apple's bi-directional Thunderbolt adapter are not officially supported and this combination is at this time untested and not recommended.
If you have any questions please feel free to contact us at support@plugable.com and we'll be happy to assist!
What does the power button on the TBT4-UDZ do and what do the lights indicate?
The power button for the TBT4-UDZ is simply to turn the dock on or off. This button does not have any influence on the computer itself (power button will not power on/off the attached host system).
When the dock is powered off all devices attached to the dock will also lose power and the dock will no longer be recognizable by the system or offer charging (until it is turned back on).
Please note that the dock will automatically power on when attached to AC power and this is indicated by a white (or green) light on the front. A white light means the dock is getting power but that it is not connected to a host system. A green light means the system is getting power and has successfully connected to a host system.
Does my TBT4-UDZ need updated firmware?
The TBT4-UDZ generally does not require for the firmware to be updated, however, in some cases a new firmware version may be helpful if you are experiencing the following issue, and after standard troubleshooting (such as driver updates and firmware updates to the host system) has not helped:
- DisplayPort attached display(s) are detected but displaying no image on screen.
Note: Updating the dock firmware will not help with other non-video related issues, if experiencing other issues please contact us at support@plugable.com and we'll be happy to assist.
If you are experiencing the above issue, to update the firmware you will need access to a Windows 10 or Windows 11 system with Thunderbolt 3, Thunderbolt 4, or USB4. (Standard USB-C systems may also support the update process if they support USB-C DisplayPort Alternate Mode.)
The firmware update cannot be performed on a Mac system, or systems running Linux. If you do not have access to a compatible Windows system to perform the firmware update please contact us for assistance.
Please follow these PDF instructions to download and perform the firmware update: https://media.plugable.com/downloads/kb/1707049/tbt4-udz_firmware_update_procedure.pdf
If you encounter any issues during the firmware update process, or have any additional questions please contact us at support@plugable.com and we'll be happy to assist.
Which port on the TBT4-UDZ dock do I connect my system to?
The TBT4-UDZ has a front Thunderbolt 4 40Gbps USB-C port that is used to connect a host system. The rear 10Gbps USB-C port is intended for USB-C accessories and will not support connecting a system there. If connecting to the wrong port by accident no damage will occur but the dock will not be recognized properly.
Is the TBT4-UDZ compatible with DisplayLink?
No, the TBT4-UDZ does not use DisplayLink USB graphics technology and does not support the DisplayLink USB graphics driver software.
External DisplayLink based devices connected to the TBT4-UDZ USB ports are supported.
How do I insert and remove media cards from the TBT4-UDZ?
The Plugable TBT4-UDZ docking station has two media card reader slots located on the front of the unit.
The first slot is for full-size Secure Digital (SD) media cards. The second slot is for microSD media cards.
Media cards can be inserted into both slots, and both can be used simultaneously.
Full-size SD card slot
The full-size SD card slot is a ‘manual’ slot. When the docking station is in the horizontal position, you simply insert the full-size SD card into the slot with the SD card label facing upwards. Continue to push the card into the dock until the card stops.
To remove the full-size SD card, simply pull to remove the card from the slot.
*** Please note, prior to removing the card from the slot you may have to manually ‘eject’ the media card from within the host operating system. ***
Full-size SD card outside of the docking station
Full-size SD card partially inserted into the full-size SD card slot
Full-size SD card fully inserted into the full-size SD card slot
microSD card slot
The microSD card slot is a ‘spring loaded’ slot. When the docking station is in the horizontal position, you simply insert the microSD card into the slot with the SD card label facing downwards until you hear a ‘click’.
To remove the microSD card, simply press on the visible edge of the card with your finger nail and then release. A spring inside the slot will gently push the card outward. Once the card has been released, continue to remove the card from the slot.

Can I leave my notebook computer connected to a charging dock overnight, or should I discharge and recharge the notebook battery regularly?
We are often asked if it is okay to leave a notebook computer connected to one of our USB-C docking stations with Power Delivery for extended periods of time. The short answer is yes, it is no different from leaving the laptop connected to the manufacturer's original USB-C power supply for the same time. The long answer is yes for modern laptops, and maybe for older (1990s-early 2000s laptops) and involves going into the different battery technologies used in consumer electronics devices.
Another common question is if it is possible to use the docking station but to disable powering and charging the computer. When a modern notebook computer runs on battery power it will often set the system to a reduced power state which may impact performance, or connected devices and we recommend always powering the computer when using a desktop docking station. For all of our docking stations that provide power to the host computer this will not affect the lifespan of the computer's battery.
Modern Laptop Batteries: Lithium-Ion
Lithium-ion (li-ion) batteries are found in a wide range of consumer electronics from notebook computers and cell phones, to electric cars, power tools, and wearable electronics like wireless earbuds. Li-ion offers fast charging, high-current discharging, fairly long service live compared to other rechargeable battery technologies and are relatively inexpensive.
The life-span of a rechargeable battery depends on many factors including age, temperature history, charging patterns, the chemical composition of the specific battery, and usage. For example batteries stored at 100% charge will degrade faster than batteries stored at 50% charge, this is why most consumer electronics devices arrive from the manufacturer with between 25% to 75% charge.
Lithium-ion batteries are consumable components, however in most modern computers, cell phones, and tablets these are not user serviceable components. To help maintain the battery all modern computers and most consumer electronics will include battery charge and protection circuits. These can be fairly simple, charging up the battery at preset rates depending on the charge level to help maintain the battery life, or complex software controlled charging that monitors battery temperature, voltage and current draw to maintain the fastest charging while maintaining the battery longevity.
Modern notebook computers can be left connected to the original power cable or a docking station with charging capability for extended periods, and do not benefit from regular discharge/recharge cycles. Our docking stations with charging capability rely on USB Type-C Power Delivery to power and charge compatible computers. USB Type-C Power Delivery is a negotiated charging protocol between the host computer and the docking station or USB Type-C power supply, this allows the computer to draw only the power it requires, and even select the best voltage level for powering the computer. In combination with a computer's built-in battery charging controller the computer is capable of maintaining the battery's optimal state even when left connected to a power source for an extended period of time.
Legacy Laptop Batteries: NiCad and NiMH
Older laptops, from the 1990s and some early 2000s, as well as some consumer electronics, and most rechargeable AA or AAA battery replacements use Nickel-Cadmium (NiCad) or Nickel-Metal Hydride (NiMH) batteries. These batteries are slower to charge and discharge than li-ion batteries, and require very simple charge controllers, and in some cases can even be trickle-charged ( very low-current continuous charging ) if desired.
These batteries generally don't have smart charging controllers and to prolong the life of the battery required "training" or fully discharging and recharging the battery every so often. Many laptop manufacturers recommended fully charging and discharging a new laptop 2-3 times to train the battery, this is not necessary with modern laptops.
Conclusion
Modern notebook batteries are managed by the computer's built-in battery charging circuit, and require little to no user intervention to maintain optimal battery health. It does not harm the battery to leave the computer connected to an external power supply, so long as the computer is being used regularly. If the computer is to be stored for a prolonged period then discharging the battery to between 50-75% can help to maintain the battery life.
Batteries are consumable components and degrade over time, however modern notebook computers can extend the battery life generally to meet or exceed the life of the computer's other electronic components.
HDMI Resolution Issues with Nvidia Graphics Equipped Notebooks
UPDATE 1/10/2024
The issue originally described within this article has been resolved by Nvidia with the release of their GPU driver, version 546.33 dated 12/12/2023 → LINK
If you are experiencing lower than expected resolution via the HDMI video outputs of your TBT4-UDZ or UD-4VPD docking station when using either product with a laptop computer with a discrete Nvidia GPU, updating to the GPU driver referenced above should resolve the issue.
If that does not help, please contact us at support@plugable.com for further assistance.
The original text of this article is being retained below, for historical reference only.
*** Deprecated information - For historical reference only ***
If you are having issues with your HDMI display(s) not working at their expected native resolution from your TBT4-UDZ or UD-4VPD docking station HDMI outputs, and your notebook computer is equipped with discrete NVIDIA graphics (or hybrid AMD/Intel + NVIDIA graphics), you may need to install an earlier version of the NVIDIA graphics driver to resolve the low-resolution behavior.
This behavior with low resolution over HDMI (usually 800x600 or 720x576) is due to a what we believe is a regression with the NVIDIA graphics driver past version 532.03. Based on our internal testing and reports from customers any newer driver version at this time will cause this low-resolution behavior.
It is our current recommendation that if you are running a newer version of the NVIDIA graphics driver and are experiencing this issue to roll-back to version 532.03 which can be found below:
https://www.nvidia.com/download/driverResults.aspx/204970/en-us/
Please note that this specific behavior only affects our TBT4-UDZ* and UD-4VPD docking stations and is currently under investigation (*TBT4-UDZ DisplayPort outputs are unaffected). Once there is a newer NVIDIA graphics driver available that does not exhibit this regression this article will be updated.
To update the NVIDIA Graphics Drivers to the compatible version:
1) Download the latest graphics drivers from NVIDIA linked above, by clicking on the green "Download" button on this and the next page, save the drivers to the Desktop or Downloads directory
2) Save and close any open applications, unplug the docking station from the computer, and connect the original power supply
3) Navigate to the downloaded graphics driver, then right-click on the saved driver installation file and select "Run as administrator" to start the installation process
4) Allow the NVIDIA driver installation through the "User account control" window
5) Select the "Custom Installation" option, and on the "Custom Installation" screen, select the checkbox next to "Perform a clean installation" near the bottom of the window, then follow the on screen instructions to update the NVIDIA Graphics Drivers

Which USB-C port on this product can be used to connect it to my computer?
For products which have multiple USB-C ports, normally only one port is capable of connecting the product to a computer. USB-C ports capable of connecting the product to a computer are sometimes called “Host” or “Upstream” ports.
On Plugable products with multiple USB-C ports, the dedicated port for connecting to the computer will be marked with a small laptop icon or the words “To host”.
A product may not be able to function if it is connected to a computer through a different USB-C port. These ports are also known as “Hub" or “Downstream” ports.
Understanding Heat Generation in Electronics
It's not uncommon for users to notice a certain level of heat generation from electronics and by extension, Plugable products during operation. In this knowledge base article, we'll explore the reasons behind this heat generation and why it is considered a normal experience within reasonable limits.
Electronics, by their nature, generate heat during operation. This is primarily a result of the electrical current flowing through various components, such as integrated circuits, transistors, and other electronic elements. As Plugable products are designed to efficiently process and transfer data (among other functionality), some level of heat generation is inherent.
Factors Influencing Heat Generation:
- Power Consumption: The power consumption of a device directly influences the amount of heat it generates. Higher power usage, especially during data transfer or charging processes, can lead to increased heat.
- Enclosure Design: The design of the product's enclosure and its ability to dissipate heat play a crucial role. Adequate ventilation and heat sinks are often incorporated to manage and disperse generated heat effectively. This is evident in our TBT3-UDZ and TBT4-UDZ designs. The metal case in these docks are designed to function as a heatsink with thermal pads placed throughout the enclosure. This allows heat dissipation from inside to the outside, but will also make it feel as if the device is “too hot”.
- Ambient Temperature: The external environment may also play a role. Higher ambient temperatures can contribute to increased perceived heat from the product. This means that summer temperatures may increase the heat generation of not just Plugable products, but many other electronic devices.
Normal Heat Levels: While it is normal for electronic devices to generate heat, Plugable products are engineered to operate within safe temperature ranges. We conduct rigorous testing to ensure that the heat generated during normal operation falls within industry-standard safety parameters. While not all products are or need to be UL certified, we try to go by UL guidelines for thermal readings. The UL threshold is 77C/170.6F, and we aim for around 71C/160F.
Tips for Users:
- Ventilation: Ensure that Plugable products have sufficient ventilation around them. Avoid placing them in enclosed spaces where heat dissipation may be impeded.
- Usage Patterns: Intensive tasks such as high-speed data transfer or charging multiple devices simultaneously may result in increased heat generation. This is generally normal but may be more noticeable in such scenarios.
- Accessories: A number of our devices will allow for the connection of USB accessories and as such, these will require power. If too many “power-hungry” devices are connected, this will cause the device to run much hotter than expected. Be sure to keep in mind the power limits of your dock/device.
In conclusion, experiencing heat from Plugable products is a normal aspect of their operation. Users can rest assured that we prioritize the safety and efficiency of our devices. By understanding the factors influencing heat generation and following simple usage guidelines, users can make the most of their Plugable products while ensuring a reliable and efficient user experience.
DisplayLink and "Screen Recording" Troubleshooting
If you have installed your DisplayLink-enabled docking station or graphics adapter and downloaded the DisplayLink software, but see that no displays are working properly, you may need to enable “Screen Recording”. In this guide, we will go over a short list of steps to enable this permission, and get your DisplayLink device up and running!
As of macOS Catalina (version 10.15), DisplayLink drivers that are installed require that the “Screen Recording” permission be granted by the user. While this permission, when used in conjunction with DisplayLink is not recording in a traditional sense, it does allow DisplayLink to access the pixels it needs to render images (mirrored or extended). It then sends these pixels over USB from the computer to the display connected to your DisplayLink connected device.
Note: It does not capture or send any data.
During the installation process for the DisplayLink drivers, you will be requested to allow “Screen Recording” for DisplayLink. Additionally, you may see a notification within the DisplayLink application and when a new device is connected. However, we understand sometimes these may get lost in a sea of information and other notifications.
How do I know if the Screen Recording permission hasn’t been set? Reference the image below to check in your “Privacy & Security” settings
If you have not enabled “Screen Recording”, please follow these few instructions to enable it.
- Click on the Apple icon (defaults to the top left corner of your screen) and select “System Preferences
- Navigate to and click “Security & Privacy”
- In this window, select “Privacy”
- A list will be presented, scroll until you find “Screen Recording” and click on it
- Displayed on the bottom left, there is a lock icon, click on this to make changes
- If prompted, login using your computer credentials to make changes
- Check the box next to DisplayLink Manager
- You will be promoted to “Quit & Reopen”, click this button
- Click on the lock icon once more to save your changes
Note: Some of these steps may vary slightly based on your macOS version
You should now be able to see your displays on your docking station or adapter. If you have completed the above steps successfully and still do not see your displays, please be sure to reach out to our support team at support@plugable.com.

Maximizing 2.5Gbps Ethernet Performance
Ethernet technology has come a long way since its inception in the late 1970s when early Ethernet operated at 10 Mbps, which was considered fast for its time. As digital demands increased, so did the need for faster data transfer speeds, leading to the introduction of Fast Ethernet (100 Mbps) and eventually Gigabit Ethernet ( 1 Gbps ), which has been the standard for home and office networking for over 20 years. Over these years, Ethernet continued to evolve, with standards being developed to handle even higher speeds but most often being isolated to the server room, and cloud computing. Today, technologies like 2.5 Gbps and 5 Gbps Ethernet have developed from 10 Gbps Ethernet, catering to modern high-bandwidth applications in both home and office environments. These advancements make it easier than ever for users to connect and transfer data at speeds that support the demands of video streaming, gaming, and extensive network tasks with higher reliability and lower latency than WiFi.
Upgrading a whole network from Gigabit to 2.5Gbps or faster can be costly and time consuming, but it doesn’t have to be done all at once. We have released both 2.5Gbps and soon 5Gbps USB Ethernet adapters that can be used with both notebook computers and desktops to provide up to five times faster Ethernet speeds than the built-in network controller, without having to install any new PCIe cards. Both of our high-speed Ethernet offerings are backwards compatible with current Gigabit Ethernet and in many cases can use the same network cables, however we do recommend replacing Category 5 and Category 5e cables with at least Category 6a or Category 7 cables to ensure future compatibility with both 5Gbps and 10Gbps Ethernet. Desktop 2.5Gbps and 5Gbps Ethernet switches are also coming down in price and can be used to quickly upgrade the network throughput between nearby computers.
As you make the upgrade process there are some steps that can be taken to ensure the network throughput is maximized between the 2.5Gbps or faster computers.
Maximizing 2.5Gbps Ethernet Performance
Maximizing the performance of a 2.5Gbps Ethernet network can enhance both speed and reliability, especially for power users who value efficiency and seamless connectivity in a busy IT environment or at home for the fastest home media center. Here are some best practices for small 2.5Gbps and 5Gbps network setups:
Upgrade Network Infrastructure for Compatibility
Switches and Routers: Ensure your network infrastructure, particularly switches and routers, supports 2.5Gbps or 5Gbps Ethernet. Many older devices are limited to 1Gbps, which will bottleneck the system.
This is most important between the computers that need the higher speed, if you have internet speed at or below 1Gbps then upgrading the router will not improve performance, so long as all computers that need faster local area network access are connected to the same 2.5Gbps or faster Ethernet switches.
Cable Quality: Use high-quality Cat 6a cables or better. While 2.5Gbps is designed to work with Cat 5e Ethernet cables, at least for short distances, for longer runs and to ensure the best performance Cat 6, 6a, or Cat 7 are recommended for 5Gbps networks.
Optimize Device Connections and Settings
NIC Configuration: Adjust your network interface card (NIC) settings to ensure optimal performance. This may involve tweaking parameters such as jumbo frames or flow control for maximum efficiency.
Ethernet data frames with more than 1500 bytes of data are called “jumbo frames”. Setting a larger frame size packs more data into each frame and can potentially reduce the CPU overhead, however to function it must be enabled on both endpoints and supported by all networking hardware in between. For most users there will be no noticeable difference in network performance, however in some specific cases like when a home server is transcoding and streaming video it can help to reduce the CPU overhead of the entire process. This can best be enabled on short point-to-point networks rather than sprawling networks, as packet loss with jumbo frames enabled causes significantly worse slowdowns than with standard frame sizes.
Flow control allows for the receiving system to transmit a pause request to the transmitting system to prevent data loss. This is necessary when multiple computers are communicating to the same server as there is generally not enough bandwidth to service all requests simultaneously, however it can be disabled in a point-to-point network setup where both computers are directly connected and both computers can handle full-speed data throughput. QoS - Quality of Service offers an alternative to Flow Control but requires significantly more setup often including managed switches and may not be an effective choice for the home and small office networks.
Driver and Firmware Updates: Keep all drivers and firmware updated for your network adapters, switches, and routers. This reduces potential compatibility issues and improves performance. Firmware updates are also important for maintaining network security, vulnerabilities in router firmware have been historically exploited to create network back doors, to exfiltrate data, as well as creating bot-nets for DDoS - Dedicated Denial of Service attacks on websites.
Drivers for Plugable devices can be found on our product pages, under the "Downloads" tab.
Consider Network Segmentation
For a network with mixed-speed devices (1Gb, 2.5Gbps, 5Gbps and 10Gbps), segmenting traffic can prevent slower devices from dragging down performance. This can be done physically by using gigabit Ethernet switches separate from 2.5Gbps or 5Gbps switches then bridging the switches together, or virtually by setting up virtual LANs (VLANs) with a managed Ethernet switch. VLANs can help allocate 2.5Gbps and 5Gbps connections exclusively for high-bandwidth tasks while lower speed devices can utilize secondary gigabit Ethernet ports on the server or client computers.
Leverage Multi-Gig Capable Devices for Key Applications
Identify the devices that will benefit the most from 2.5Gbps and faster connections, such as NAS - Network Attached Storage systems with integrated 2.5Gbps or 5Gbps Ethernet, high-performance workstations or desktop replacement notebooks with USB Ethernet adapters, or servers with multi-port bonded Ethernet controllers handling large data transfers. Connect these devices directly to a switch that can take advantage of the higher network throughput to ensure they receive the best performance possible.
Future-Proofing with 2.5Gbps-capable or faster Docking Stations and USB Ethernet Adapters
Many Plugable docking stations now support 2.5Gbps Ethernet, which could be ideal for enhancing productivity for hybrid work setups, at home, or in the classroom by enabling high-speed, wired connectivity. Plugable’s docks also simplify integration across Windows and Chrome OS devices, which can be especially helpful in mixed-device environments.
