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
Fred the Oyster, CC BY-SA 4.0 , via Wikimedia Commons
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.

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.

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.
What do the two indicator lights on the front of the TBT4-UDX1 mean?
When the TBT4-UDX1 is connected to an electrical power source and powered on, there will be a small solid green power indicator light present on the front of the unit.
When the TBT4-UDX1 is connected to a compatible host computer, there will be a small solid blue host connection indicator light present on the front of the unit.
Does the TBT4-UDX1 charge my computer, and if so, at what rate?
The TBT4-UDX1 can provide up to 96W of power to charge a compatible host computer.
The TBT4-UDX1 has two downstream Thunderbolt ports. Each time a device is connected to one of these ports, the amount of power provided to the host computer is lowered by 15W.
For example, if there is one device connected to a downstream Thunderbolt port, the total amount of power provided to the host will be 81W.
If there are two devices connected to both downstream Thunderbolt ports, the total amount of power provided to the host will be 66W.
How many external displays can I connect to the TBT4-UDX1?
The TBT4-UDX1 is a Thunderbolt 4 docking station based on the Intel Goshen Ridge chipset. The display output capabilities of the TBT4-UDX1 are ultimately determined by the display output capabilities of the host system.
Thunderbolt 4 host system:
When the TBT4-UDX1 is connected to a computer with a Thunderbolt 4 port, the maximum number of displays that can be connected to the docking station is two.
The TBT4-UDX1 has a built-in HDMI video output port, and two downstream Thunderbolt ports.
We include in the box with the TBT4-UDX1 a Plugable USB Type-C to HDMI adapter that can be connected to one of the docking stations downstream Thunderbolt ports.
The video outputs via the TBT4-UDX1 are provided on a ‘first come, first served’ basis. To expand further, if the dock’s built-in HDMI video output is in use, you can connect one additional display via a USB Type-C to video adapter.
If there are two USB Type-C video adapters connected to the dock’s downstream Thunderbolt ports, then the HDMI video output will not function.
Thunderbolt 3 host system:
Manufacturers have discretion when designing their Thunderbolt 3 systems in regard to how many displays are supported via a single Thunderbolt 3 port. Some Thunderbolt 3 systems support two displays, while other Thunderbolt 3 systems will only support one display.
The same ‘first come, first served’ process described previously within the ‘Thunderbolt 4 host system’ section will still apply if the host system supports two displays.
USB Type-C host system:
Host systems with only a USB Type-C port will be limited to a maximum of one display. This display can be connected to either the dock’s built-in HDMI video output port, or via the included USB Type-C to HDMI adapter.
What are the maximum display resolutions and display refresh rates supported when using the TBT4-UDX1?
The maximum display resolution supported when using the TBT4-UDX1 is 3840x2160, and the maximum refresh rate supported is 60Hz.
Resolutions higher than 3840x2160 and refresh rates higher than 60Hz are not supported.
Does the TBT4-UDX1 have any type of media card reader built-in, and if so, what are its specifications?
The TBT4-UDX1 has one full-size Secure Digital (SD) card reader slot located on the front of the unit. The SD card slot supports the SD 4.0 specification, and the UHS-II standard.
What type of mechanical mechanism does the SD card reader within the TBT4-UDX1 utilize?
The SD card reader utilizes a ‘friction’ mechanism in order to retain the SD card. To insert a SD card, simply insert the card into the slot until the card stops. The card will remain partially exposed when fully seated. To remove the card, simply pull the card from the slot (note, please be sure to eject the card from within the host operating system when doing so).
What is the transfer rate of the TBT4-UDX1’s USB Type-A ports?
The TBT4-UDX1 has four USB Type-A ports, one is located on the front of the unit and three are located on the back of the unit.
Each USB Type-A port supports 10 Gbps data transfer rates.
Does the TBT4-UDX1 have a power button, and if so, how is the unit turned on?
The TBT4-UDX1 has a power button located on the front of the unit. When the unit is connected to an electrical power source, the dock will power on automatically.
The unit can be manually powered off by pressing the power button once. After the unit is manually powered off, it can be manually powered back on by pressing the power button once.
What are the two slots/holes located on the left-hand side of the TBT4-UDX1?
The two slots located are the left-hand side of the TBT4-UDX1 are anchor points that can be used for physical security cables (i.e. Kensington locks).
What types of devices can be connected to the TBT4-UDX1’s downstream Thunderbolt ports?
You can then connect many different types of Thunderbolt and USB-C devices to the two ‘downstream’ Thunderbolt/USB-C ports on the back of the dock. The type of functionality provided by the two ports on the back of the dock is ultimately determined by the capabilities of the host computer.
To put that another way, if the host computer has Thunderbolt 4 technology built-in, then both ports on the back of the dock will function as Thunderbolt 4 ports.
If the host computer has USB-C technology built-in, then both ports on the back of the dock will function as USB-C ports.
If the host computer has Thunderbolt 3 technology built-in, then both ports on the back of the dock will function as Thunderbolt 3 ports***
*** Please note, the specifications of a Thunderbolt 3 host system can have an impact on the level of functionality of the dock’s downstream ports ***
When a Thunderbolt 3 host system that has:
A. An Intel Titan Ridge Thunderbolt host controller
B. A DCH variant of the Thunderbolt host controller driver higher than version 1.41.613.1 installed
C. An internal Thunderbolt NVM firmware version of 41 or higher
Is connected to the dock, then both downstream ports will function as Thunderbolt 3 ports.
When a Thunderbolt 3 host system that has:
A. An Intel Alpine Ridge Thunderbolt host controller
B. A DCH variant of the Thunderbolt host controller driver installed
Is connected to the dock, then one downstream port will function as a Thunderbolt 3 port, and the other port will function as a USB Type-C port.
What are the capabilities of the TBT4-UDX1’s Ethernet network port?
The TBT4-UDX1 has a wired Ethernet network port based on the Realtek RTL8156B chipset. The Ethernet port can support up to 2.5Gbps Ethernet when connected to compatible 2.5Gbps Ethernet network infrastructure (both the Ethernet switch and Ethernet cables in use must support 2.5Gbps operation).
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.

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.

Many modern displays can support above the default 60Hz refresh rate, however this may need to be manually set within Windows 11. Please note, not all computers, graphics adapters, and docking stations can support all resolutions and refresh rates.
Setting the Display Refresh Rate in Windows 11
1. Right-click on the desktop and select Display Settings from the drop-down menu
2. Scroll down to the Related settings subsection and select Advanced display
3. At the top of the Advanced display window, select the external display from the drop-down menu
4. From the Choose a refresh rate drop-down menu select the desired refresh rate
Refresh Rate Limitations
With Windows 24H2 and newer, dynamic refresh rates are supported, this allows the system to adjust the display refresh rate to save power, up to the selected refresh rate. As a consequence of this new mode, when selecting the display refresh rate you may see an asterisk. This indicates that selecting the specific refresh rate may reduce the display resolution or image quality in order to prioritize the refresh rate. This exposes the refresh rate option from the display even if the display cable or computer is incapable of supporting that refresh rate at the native resolution and is the intended behavior per Microsoft. [1]
In the screenshot below the left side shows the 4K 120Hz capable display limited to 60Hz refresh rate without asterisks, and on the right the same display after setting the refresh rate to “120 Hz*”, the “Desktop mode” resolution has been reduced to 2560 x 1440 (1440p) instead of 3840 x 2160 (4K UHD). Unlike when using the display scaling option this also causes a reduction in image quality. On the right side asterisks are no longer shown in the refresh rate list. Setting the refresh rate back to 60Hz does not change the resolution, you will have to go back one page and set the resolution manually.

Is this safe to use if my computer doesn't support USB-C Power Delivery?
USB-C Power Delivery (PD) is negotiated between the power-sourcing equipment (e.g., a dock or multiport hub) and the connected host device. During this negotiation, the device offering power communicates its capabilities, and the host determines whether it can accept the power. If the host does not support Power Delivery, no power will be sent to the computer over the USB-C connection. This will allow you to take advantage of other capabilities such as data transfer or video output without risking damage to the computer.
Is there a way to add more displays to my dock?
Extra displays can be added to your docking station by using USB graphics adapters. This allows you to expand your workspace beyond the number of displays natively supported by your dock or computer.
Here’s how it works:
- Ensure your dock has open USB-A or USB-C ports to connect the USB graphics adapter(s).
- Select a Plugable USB graphics adapter compatible with your operating system and monitor specifications. Feel free to contact Plugable support (support@plugable.com) for assistance in selecting the appropriate adapter for your setup.
- Download and install the driver from the "Downloads" section of the product page for the USB graphics adapter on Plugable's website.
- Plug the adapter into an available USB port on your docking station.
- Use an appropriate video cable (e.g., HDMI, DisplayPort) to connect the adapter to your monitor.
Important Considerations:
- Windows supports up to 8 DisplayLink/SiliconMotion-based monitors.
- macOS has a hard limit of 4 DisplayLink/SiliconMotion-based monitors.
- USB graphics adapters use bandwidth and system resources. Connecting multiple adapters can reduce performance.
How Can I Check the Ethernet Adapter Link Rate on my Mac?
One helpful way to identify your ethernet link rate speed is through the System Settings app in macOS. This can help us identify if your Plugable ethernet adapter is negotiating either 1Gbps or 2.5Gbps network speeds. Some routers have a mix of 1Gbps or 2.5Gbps ports, and in the macOS System Settings this will be shown in the Speed field.
In this example, we will be analyzing our USBC-E2500, which is a 2.5Gbps ethernet adapter. This method applies to all of our ethernet adapters, such as:
Navigate to the Network section, select the entry named “USB 10/100/1G/2.5G LAN” with the Green - Connected icon. Expand the Details button, and go to Hardware.
In the field that says Speed, you should see 2500Base-T if the ethernet adapter is connected to a 2.5G ethernet LAN port on your router. If you see 1000Base-T, this means the adapter is connected to a 1G ethernet LAN port. If you are expecting faster network speeds, please see your router's documentation on its multi-gig LAN port.
Choosing the Right USB Type-C Cable for Your Docking Station
At Plugable, we rigorously test our docking stations with the included accessories to ensure they work seamlessly together. One key reason for using the included cable is that not all USB Type-C cables on the market support the same features. Therefore we strongly recommend using the USB Type-C or Thunderbolt cable that comes with your Plugable dock for best results.
Understanding the differences between charging and data cables is essential to fully enable your new docking station, or if you are ever in need of a replacement or longer cable for your docking station. Let’s break it down.
USB Type-C Cables: Charging vs. Data
USB Type-C cables may look identical, but their capabilities can vary significantly. Unfortunately, the USB specifications do not require cables to be clearly labeled, which can make identifying the right cable a challenge.
There are two main categories:
USB Type-C Charging Cables
Charging cables are among the most common Type-C cables available. They typically support:
✔ USB 2.0 data (up to 480Mbps)
✔ USB Power Delivery for charging devices
These cables are often included with smartphones, tablets, and some laptops. They are also frequently sold specifically for charging purposes. However, they lack the necessary conductors for high-speed data transfer and video output.
Fully Featured USB Type-C Cables
Fully featured USB Type-C cables offer full functionality and are required for docking stations. The cables we include with our USB Type-C docks support:
✔ USB4 or USB 3.0/3.1 data (5Gbps or faster)
✔ USB 2.0 data
✔ USB Power Delivery
✔ USB Type-C DisplayPort Alternate Mode for video output
These cables ensure full compatibility with our docking stations, allowing for both high-speed data transfer and external display support.
Thunderbolt Data Cables
Thunderbolt cables are a specialized subset of USB Type-C data cables. They are Intel-certified and typically marked with the Thunderbolt logo (⚡).
✔ Interchangeable with USB Type-C data cables when using USB 3.x devices
✔ Required for Thunderbolt devices to ensure proper functionality
If you're using a Thunderbolt docking station or device, a certified Thunderbolt cable is essential for maximum performance.
What Makes These Cables Different?
The key difference lies in the internal wiring:
🚫 Charging cables lack the conductors required for high-speed data (USB 5Gbps or higher) and video output. Even if a device supports USB Type-C DisplayPort Alternate Mode, a charging cable won’t transmit video.
✅ Data cables include additional wiring to support higher data rates, video output, and greater flexibility in bandwidth allocation.
How Can I Tell the Difference?
🔎 Charging cables are generally thinner and may have smaller connector grips, as they often lack electronic markers. They are typically advertised as:
- "Charging cable"
- "480Mbps data rate"
- Advertised primarily for phones and tablets, not laptops
🔎 Data cables are usually thicker and slightly more expensive due to their additional complexity. Look for statements such as:
- "USB 3.0/3.1," "USB4," or "Thunderbolt"
- "5Gbps" or faster data rates
- Mention of video support for use with external displays
⚠ Cable Length Matters!
Fully featured data cables are typically limited to 1 meter (3.3 feet) to comply with USB Type-C specifications. Charging cables, on the other hand, can be much longer.
Need a Longer or Replacement Cable?
If you need a replacement or a longer cable for your USB Type-C or Thunderbolt docking station, consider these options:
For USB 3.1/3.2 Type-C Docking Stations:
🔗 USB Type-C 10Gbps 1m (3.3ft) Cable
For Thunderbolt & USB4, and USB 3 Type-C Docking Stations:
🔗 Thunderbolt 4 40Gbps 1m (3.3ft) Cable
🔗 Thunderbolt 4 40Gbps 0.8m (3ft) 90° Right-Angle Cable
🔗 Thunderbolt 4 40Gbps 2m (6.6ft) Cable
Note: The USB Type-C 10Gbps cable is only recommended for USB 3.x docking stations, not Thunderbolt docks.
