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.
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.
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.
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
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.

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.
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.
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.
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.
A network interface represents connections, whether wired or wireless, that are made to form a network between devices.
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.
To properly benchmark network adapter performance, we need to:
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.
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 .
cmdin the window that appears
Command Prompt, and open it
cdcommand is for 'change directory'
sudo apt install iperf3
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.
cmdin the window that appears
Command Prompt, and open it
cdcommand is for 'change directory'
iperf3.exe -c 192.168.0.200 -t 30 -P 4
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.
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.
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.

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:
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:
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:
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.

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 firstname.lastname@example.org 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.
Plugable docks do not officially support monitors with a 120Hz or 144Hz refresh rate (only 30Hz or 60Hz depending on the product).
Monitors with refresh rates higher then 60Hz should be connected to a video output directly on the computer to ensure the display is powered by the system's native GPU.
When connecting to a monitor that accepts a USB-C input, from a docking station that outputs DisplayPort (such as the UD-6950, UD-6950Z, UD-6950H, TBT3-UDZ, TBT3-UDC3), you will need to use a DisplayPort to USB-C "Bi-Directional" cable. This is because many USB-C to DisplayPort cables are unidirectional and only send data in one direction, from USB-C source device to a DisplayPort input port on a monitor.
An example of a DisplayPort to USB-C "Bi-Directional" cable can be seen here: https://www.amazon.com/dp/B081VK1KHV
For Thunderbolt 3 systems:
Some systems with Thunderbolt 3 support may only have the ability to connect a single display through the Thunderbolt 3 port. This is due to how the system manufacturer has configured the internal circuitry of the computer between the system graphics card and the system Thunderbolt 3 controller. To be specific, they have only routed one DisplayPort video line/stream from the graphics card to the TBT3 controller.
As an example of this, many Intel NUC systems only support a single display, see here for reference: https://www.intel.com/content/www/us/en/support/articles/000021752/intel-nuc.html
We also see this configuration on many high end gaming laptops or desktop replacement workstation laptops that have one or more dedicated onboard video outputs. Unfortunately, this is often undocumented and you may need to contact your system manufacture to verify if they expect dual monitors will be supported over Thunderbolt 3.
Apple M1 based Macs (MacBook Air, Mac Mini, and MacBook Pro) only support a single display through Thunderbolt 3 or USB-C. (This is a limitation of the M1 graphics card design.)
For USB-C systems:
Apple USB-C only systems (without Thunderbolt 3 support) like the 2015 MacBook Retina 12" can only support a single display or will show two screens with mirrored images. This is because Apple does not support DisplayPort MST (multi-stream) which our dock uses to take a single USB-C DisplayPort Alternate Mode video line and connect two displays through it.
Windows USB-C systems should support MST in most cases, if you're only able to connect a single display, please contact us via email@example.com for further assistance!
Based on customer reports and information online found after this update, it appears that there is a regression in macOS Big Sur 11.1 that is causing video output issues through Thunderbolt 3 devices like our dock such as only a single display works versus two working prior with macOS Big Sur 11.0.1, or video resolutions and/or refresh rates are incorrect (example: only 4K @ 30Hz possible vs expected 4K @ 60Hz).
We encourage you to report these issue to Apple using their feedback form located here: https://www.apple.com/feedback/macos.html
Unfortunately, to resolve this issue you'll need to restore to a previous backup of your system if available for macOS Big Sur 11.0.1 or wait until the next update from Apple.
There is a known issue with the Apple provided built in macOS Ethernet drivers for the Realtek RTL8153 USB 3.0 Ethernet chipset used in our dock (and many other docks and USB Ethernet adapters on the market). When put to sleep, the problematic driver creates an Ethernet broadcast storm which can overwhelm some Ethernet routers.
For macOS Catalina 10.15.x users, please contact us via firstname.lastname@example.org and we can provide you with an updated driver and installation instructions.
For macOS Big Sur 11.x users, this behavior can be rectified by updating the host system to macOS Big Sur version 11.3 (released by Apple on 4/26/2021).
If you are unable to install third party drivers for macOS 10.15.x or are unable to upgrade from macOS Big Sur 11.x to 11.3, we recommend to disable your Mac from sleeping to prevent this issue, or use WiFi instead of Ethernet until you are able to install the driver at a later date or upgrade to the new macOS version.
If you need further assistance feel free to contact us via email@example.com and we'll be happy to help!
For Thunderbolt 3 systems a longer cable can be used, but there are some important factors to consider. The longest passive Thunderbolt 3 cable rated for 40Gbps (required for dual displays via TBT3) at this time is already included and is 0.8m in length. Longer cables will need to be active cables. We don't sell any active cables but they are available at up to two meters.
For users with USB-C only systems a Thunderbolt 3 cable is not required. Instead, a longer USB 3.1 Gen 2 cable rated for 10Gbps can be used. We recommend no longer than 2m in length. However, due to the varying quality of USB-C cables on the market, a better alternative would be a 2m 20Gbps passive Thunderbolt 3 cable like our TBT3-20G2M: http://plugable.com/products/tbt3-20g2m
Please note: For docks with 60W (watts) Power Delivery charging capabilities a cable that supports 3A (amps) minimum is required. For docks that support greater than 60W (65W, 85W, 96W, 100W) charging, a 5A cable is required.
For Intel based MacBook Pro models with four Thunderbolt 3 ports, some users have found connecting the dock to the left or right side to be more stable than the other. Due to some variance in MacBook designs, we've found it is best to experiment with your particular setup to find what works well for you. With that said, there are some specific situations where a particular side may be inherently better:
1) Older MacBook Pro models have had varying capabilities depending on the side used:
2) It has been suggested for 16" MacBook Pro owners to connect to the right side for the best performance. ExtremeTech has a great article about why this is here: http://extremetech.com/computing/309802-charging-a-macbook-on-the-wrong-side-can-significantly-lower-its-performance
3) It is also worth mentioning that per side of Thunderbolt 3 Intel based MacBooks, a maximum of two displays are supported. If using the dock on one side of the system for two displays, another display cannot be connected to the second Thunderbolt 3 port on that same side (this means Intel based MacBook Pros with only two ports will support only two displays).
Thunderbolt 3 MacBook Pros with four ports (two on each side) can support either two or four displays maximum depending on the system configuration. Intel graphics based four port models are limited to two displays only whereas AMD based graphics four port models can support four displays.
Example: You want to connect three or four displays to your four port AMD graphics based MacBook Pro, you will need to connect the dock to one side for two displays and the third or fourth displays must be connected to the opposite side of the system.
Note: Currently, M1 based Macs (MacBook Air, Mac Mini, and MacBook Pro) only support a single display through Thunderbolt 3 or USB-C. This is a limitation of the M1 graphics card design.
Please feel free to contact us at firstname.lastname@example.org if you have any questions!
The USB-C ports (excluding the host connection) on our TBT3-UDZ, TBT3-UDC3, and TBT3-UDC1 do not support video output. This means that USB-C/Thunderbolt monitors as well as USB-C video adapters will not output a display when connected to these ports.
Our TBT3-UD1-85W and TBT3-UD1-83 docks have a downstream Thunderbolt 3 port that can support video output up to 4K resolution @ 60Hz, so USB-C/Thunderbolt monitors as well as USB-C video adapters should output a display when connected to these ports.
Update 11/1/2021: We're happy to report this issue can now be resolved by updating from macOS Big Sur 11.x to macOS Monterey 12.0.1.
Plugable has been able to reproduce this problem internally and it has been raised to Apple for closer investigation. This issue appears to be from a regression introduced with the macOS Big Sur 11.4 update and is still present through 11.6.
This problem can occur when displays are connected to the docking station while the dock is reconnected to a Thunderbolt 3 port on a MacBook Pro 16" using the host Thunderbolt 3 cable (hot-plugged).
This kernel panic issue currently affects any docking station (Plugable-branded or otherwise) that uses what is known as DisplayPort Multi-Stream Transport (MST) to power one or more of the video outputs on a docking station. It is also specific to the MacBook Pro 16" system—other Mac systems do not exhibit the same problem.
To workaround this issue, we recommend disconnecting any HDMI displays from the dock before plugging the Thunderbolt 3 cable into the computer. Then, once connected, you may reconnect the HDMI display(s) to the dock.
IEC power requirements for this class of device require that charging via USB not exceed 100W peak charge rate for more than 5 seconds, and so Thunderbolt certification requires a 4W margin to maintain this IEC compliance. Because charging output from any device will always have some amount of variance, implementing a 96W Power Delivery profile combined with robust circuit design ensures the TBT3-UDZ will meet these requirements and achieve 96W sustained charging, with a peak rate of 100W. We are unaware of any real-world scenarios where this will affect charging behavior, but will certainly provide updates if we learn of any edge cases.
No, the TBT3-UDZ supports a maximum of two monitors via "Display 1" and "Display 2" video output "banks" in the following configurations:
For additional details about supported displays, see here: https://kb.plugable.com/en_US/docking-stations-and-video/what-are-the-display-output-capabilities-for-the-tbt3-udz
We have been tracking reported issues where externally connected USB devices and/or internal USB devices within the TBT3-UDZ docking station (Ethernet, audio, and card reader) may not be detected after waking the system from sleep or after rebooting on some macOS systems (typically only with M1 based Macs).
Some users may also experience one or both displays attached to the dock not waking from a low power sleep state as well (can affect both M1 and Intel based Macs).
If running macOS Catalina 10.15.x or macOS Big Sur (prior to 11.3) and are experiencing issues with the Ethernet only, please see: https://kb.plugable.com/776031
To begin troubleshooting USB device and/or display issues:
If using an Intel based Mac we recommend the following steps:
If using an M1 based Mac we recommend the following steps:
If these initial troubleshooting steps do not help, please contact us at email@example.com and we'll be happy to assist you.
The TBT3-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 mode and USB-C DisplayPort Alternate mode.
Systems with Thunderbolt 3 (or 4) 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).
In either TBT3 or USB-C DP Alt modes, a maximum of two displays are supported and can be connected in any combination of HDMI + HDMI, DP + DP, or a mix of HDMI + DP to the "Display 1" and "Display 2" output groups. See below for more details:
