Ud-3900 Driver

[Christian Swindler]

DoI overwrite the current driver or do I need to uninstall the old driver first? Any other things to do or setting to tweak before installing new driver ? I have already updated my USB 3.0 Hub Firmware to version 9084.

Designed for those who want a one-stop upgrade for your USB 3.0 laptop. The Plugable USB 3.0 Universal Laptop Docking Station for Windows (UD-3900) allows you to add dual monitors, and connect your peripherals, all through a single cable back to your laptop. Quickly come and go from your desk with ease. By connecting one cable to your laptop, you gain 11 extra ports of connectivity, making it easier to do more work in less time.

Power users with dual monitors: The UD-3900 is the dock you need to maximize your productivity and your workspace. Great for business uses such as email, web applications, Microsoft office, and more. Featuring a vertical design, you can easily slip this dock between your monitors and save valuable desk space. Conveniently access the front USB and audio ports for those devices you plug and unplug everyday.

Note: The UD-3900 will not charge your laptop and will need your external charger to provide power to your system. The UD-3900 has one HDMI port and one DVI port and we include both a DVI to VGA adapter and a DVI to HDMI adapter if needed (not compatible with DisplayPort displays).

Get more screen space for more productivity. Multiple monitors have been proven to increase productivity, and will change the way you manage your out of control tabs and your workflow.

No more grainy visuals and tiny screens. Watch videos on clear and sharp dual HDMI 60Hz screens (1920x1200 @ 60Hz). Expand your screen real estate with this dock and cut down the time it takes to work on those highly productive tasks.

Not only does this dock expand your connectivity, it also brings a whole new level of performance and flexibility.

Featuring DisplayLink graphic technology, you can connect this dock to a USB 3.0 Windows laptop. So whether you're hoteling at a desk for work, or sharing your dock at home, this dock provides the flexibility you need.

The vertical orientation is designed to reduce its desk footprint to give you more room for the things that matter most. With easily accessible ports on the front of the dock, you can unplug your headphones with ease.

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 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.

This document covers steps to resolve the most common issues enabling video from Plugable products with DisplayLink technology on Mac. In order to use a Plugable DisplayLink device on Mac, the following actions are necessary:

If the actions above are not taken, then the Plugable DisplayLink device will not work as expected. If after having taken all of the actions above your Plugable DisplayLink-based product is not working, please reach out to us directly via sup...@plugable.com and we will be happy to assist you further.

When a Plugable DisplayLink device is not working as expected with a Windows system, the best practice is to disconnect the device from the host system (and remove it's external power source, if it has one) and perform a 'clean' manual installation of the latest version we recommend of the required DisplayLink software driver to help ensure both are in a good state. To do so, please follow these steps:

If, after having completed this process, your Plugable DisplayLink device is still not working as expected, please reach out to us directly via sup...@plugable.com with the output of our PlugDebug diagnostic utility and we will be happy to help

The graphical software utilities provided by Intel, NVIDIA and AMD/ATI are designed to only recognize and work with graphics adapters made by their respective manufacturers. As a result, they will not recognize USB-attached displays connected to a DisplayLink-based docking station or graphics adapter.

The DisplayLink driver does not support color calibration functionality of any kind. Most monitors have built-in controls that can be used to adjust the characteristics of the display, though we realize this approach may not be ideal in all cases. For environments that necessitate near-perfect color reproduction and display calibration capabilities via software, a dedicated graphics card is recommended.

No, Plugable does not recommend or support using our DisplayLink-based docking stations with a traditional KVM switch. If you simply need to share the dock between two systems, the dock can be manually disconnected from the first system and then manually connected to the second system.

For those using our USB 3.0 DisplayLink docking station products that would like a more permanent solution that does not require disconnecting the unit from the host system, our Plugable USB 3.0 Sharing Switch can be used as an alternative to share the dock between two systems (please keep in mind that the dock can only be used by one system at a time).

Any time a USB 3.0 device is connected to a laptop system, there is a potential that the USB 3.0 connection can generate interference that can affect the performance of the laptop's built-in Wi-Fi adapter.

While the items listed above can help with Wi-Fi interference, there is another type of interference that can sometimes cause problems with wireless keyboards and wireless mice which we refer to as Radio Frequency (RF) interference.

If a USB 3.0 connection is generating interference, this can affect the behavior of a wireless keyboard or wireless mouse. This behavior typically manifests as inconsistent mouse movement and/or inconsistent or sporadic keystroke registration.

In some less common instances on Windows computers, erratic keyboard/mouse behavior can be related to an issue with Intel Management Engine. We've written about this issue and the workaround that may fix it in another article in our Knowledge Base: -stations-and-video/laggy-mouse-or-keyboard

There are different versions of the macOS driver that have been released by DisplayLink (the separate company that makes the primary chip within our DisplayLink-based products, and who also develops the software driver), with each version aligning with different versions of macOS. When first introduced there were several differences between the two driver versions. Over time, these differences have become fewer with updates to both the DisplayLink Manager and macOS, however this article is being retained for historical reference.

*** Display rotation on Macs with an Apple CPU is accomplished within the DisplayLink Manager Application. It is NOT accomplished via the 'Displays' System Preferences application. More information on this feature is available here: Link

**** There is a 3rd-party application called 'f.lux' that allows the adjustment of a display's color according to the time of day. This functionality is in 'beta' status, and must be enabled within the DisplayLink Manager Application in order to function. This functionality is supported with devices based on the DisplayLink DL-3xxx chipset, DL-5xxx chipset, and DL-6xxx chipset. However, it is important to note that on DL-6xxx chipsets this functionality is limited to DisplayPort video outputs only. It is NOT supported on HDMI video outputs via DL-6xxx chipsets.

1. After installation, the DisplayLink Manager app will start automatically and the DisplayLink Manager logo will show in the Menu Bar. It will be grey when the dock is disconnected (Connection status will show: No monitor detected) and white when connected (Connection status will show: Monitor detected).

NOTE: The DisplayLink Manager app will only start on its own once after the initial installation. Step 5 shows how to setup the app to always start after logging-in (recommended). Otherwise the app has to be started manually each time (see step 2).

NOTE: From macOS Catalina 10.15, the operating system requires the user to permit "Screen Recording" in order for DisplayLink based devices (like Plugable UD-3900) to work properly. The message is generated by the OS and the screen is not actually being recorded by DisplayLink. Approving it enables the DisplayLink driver to access the pixels it needs to render a mirrored or extended screen and send the pixels over USB from your computer to the DisplayLink display. DisplayLink Manager does not store or record any screen content.
