Windows 10 - Blank Screen/Mouse Pointer Only

[Dom C]

Hi All -

I am a first-time poster but a long-time reader. I've been trying to troubleshoot a USB Dock that uses DisplayLink graphics.

I have a Plugable UD-3900 that I received in September 2016 (to replace a one that I received in August 2015). I have already troubleshooted with Plugable and they were awesome to work with.

The tech from Plugable and I came to the conclusion that the issue probably stems from some sort of incompatibility with the drivers from my graphics card and since my graphics card is on legacy status, I was pretty much out of luck. I have an HP Envy 15 laptop with AMD Radeon 8650G/8750M APU/GPU dual graphics card.

Anyway, I have tried ALL of the troubleshooting on DisplayLink's website as well as all of the suggestions of the people on this forum. I have used many monitors, cables, and configurations (even rolling back to older DisplayLink and AMD drivers, turning off dual graphics, updating my BIOS, and etc.). I just cannot get the dock to work! Before I completely give up on this dock, I was hoping that someone on the forum might have further suggestions? I have attached the zip logfile.

Thanks for your time and attention!

PS - I forgot to mention...the symptom that my secondary monitor is exhibiting is that Windows recognizes it, but only a black screen with a mouse pointer shows up. Sorry I forgot to mention that!
