I’ve had the UD-3900 for several months and it has always worked great, no issues to speak of. I have an Asus Q302 notebook that I plug into the docking station so I can use an external keyboard/mouse, ethernet, bluetooth dongle, speakers, and dual external monitors without having to plug each in individually. I typically turn off the display on the notebook and use only the two external monitors.
This past weekend, the Windows 10 Anniversary update installed on my computer. The next time I plugged into the docking station, everything still worked fine (i.e., monitors, mouse, ethernet, bluetooth dongle, sound, etc.), with one small exception.
When using the external monitors, my mouse and keyboard seem to have a brief 1-2 second delay/lag followed by a “catch up” in which the mouse moves to where it should be or the keystrokes entered show up on the screen. This includes mouse clicks and click wheel movements. This happens almost every time there is an input when the mouse or keyboard haven’t been used in past 10-15 seconds, and also happens intermittently during continued use. This doesn’t totally ruin the functionality, however, the delay often makes me think that the mouse movement/keyboard input wasn’t received so I repeat it, thus after the “catch up” I have two or more of the keystrokes or mouse movements. This only happens when using external monitors. If I turn off the external monitors and use only the notebook display, while still connected to the docking station, this lag and “catch up” does not occur.
Please advise as to how best to resolve this issue. I have already updated all drivers, including the DisplayLink and the wireless mouse/keyboard.
