Display lags when I open Steam/Any Games


I just got a UD-3900H Docking Station and I hooked it all up and it worked fine. But once I opened Steam my display started lagging horribly. I have all my drivers updated, and I’m using latest version of Windows 10. Even with Steam closed, there is a slight delay. Not too bad, but noticeable. Steam just makes it worse. I’ve looked everywhere and haven’t found a fix for this yet. Please help.



Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

Unfortunately gaming is not supported over USB docking stations like ours. We mention this on our website:

Our DisplayLink-based USB graphics adapters and docking stations are “virtual” devices where much of the heavy lifting is done by the host system’s CPU, by hooking into the graphics stack. The DirectX and OpenGL APIs used by many games assume direct hardware access (a PCIe graphics card). DisplayLink’s drivers attempt to emulate as much of the functionality as possible, which is why some 3D functionality (like that needed for desktop and apps) works.

We don’t recommend running games with DisplayLink-based USB graphics products, because this emulation cannot be perfect, and often APIs used by games (DirectX and OpenGL) prevent DisplayLink devices from functioning properly. Even without specific compatibility problems, performance will always be a challenge - the extra CPU work required for USB graphics will be a source of reduced frame rates and problems. Normal desktop and application use are fine because they don’t push the system as hard as a 3D games will.

Common problems experienced when trying to run a game on a USB graphics adapter include:

  • Games not launching
  • Games crashing
  • Screen flickering
  • Screen going black

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
