I recently purchased a ud 3900 docking station on amazon and it works pretty well except for a small lag in the display of an external monitor.
I’m using an xps 15 and the monitor is hooked to the docking station with a standard hdmi cable in extended screen mode on windows 10. The lag is most noticeable with my mouse pointer. I know it’s not an issue with the mouse because when I connect the hdmi cable straight into my laptop there is no lag with the mouse at all even when the mouse is plugged into the docking station. So it’s just an issue with the display.
Any advice on what I could do to fix the display lag?
