I didn't watch the video link you sent in full. I stopped somewhere where Linus starts talking about 7 graphics card. Unlike Linus, I don't get sponsored by anyone.
I do note that the post is on ESXi so I guess the purpose is some sort of graphics passthrough without using expensive Quadro or Tesla cards.
Well I have a USB 2.0 display adapter that I haven't used in years. But I don't have an ESXi environment (yet). I do have Workstation 12.5.5 on Windows 10 and Fusion 8.5.6 on macOS.
On the Windows 10 host, the USB display link seems OK.
But on the VM, a different story.
When I did connect the USB display adapter to the VM, the Windows 10 x64 VM automatically configured extended to multidisplay. The mouse pointer and some other things went crazy.
Examples:
When I right click on Start button (using two finger tap), it wasn't bringing what the Windows-X key combination dialog but bringing out the Right Click on Taskbar.
I couldn't expand the Display in the Device Manager of the VM to see what was driving it.
I couldn't get pass the point to re-align the 2 displays in Display settings. It had automatically configured the displays to be side-by-side but the mouse pointer just disappears when I try to go there to re-align the displays.
I did install the latest DisplayLink drivers for Windows 10 on both the host and VM.
