I just connected my UD-3900 and I am getting lagging and freezing on my display to the point that it is unusable. The laptop display runs fine as does the external display when connected directly to the laptop (via a DVI to HDMI cable), but as soon as I connect the display through the dock, the lag is there.
I have followed the steps from other posts and uninstalled (using the DisplayLink Cleaner) then reinstalled the drivers which did not fix the issue (Windows 10 Pro was completely up to date). Where to go from here?
Edit: Since my initial post, I connected the external monitor to the docking station with a standard DVI cable (monitor DVI out to dock DVI in), and I’m still having issues.
RESOLVED: For anyone else with the issues described here, i was able to resolve the issue by disabling hardware acceleration in the applications that caused issues.
My laptop has two video cards, the built-in as well as an NVIDEA add-on card. Apparently what was happening is applications were sending the hardware acceleration to the wrong card which caused a cascade failure. If you have a similar setup with lag issues, you may want to try this.
The downside of this is that I have to bypass my NVIDEA card as well as not being able to use hardware acceleration.
