hi,
unfortunatelly, I can only confirm, latest DisplayLink results in an error:
failed to initialize renderer unknown error creating the renderer
I use windows 8 64-bit
after a bit of fiddling, if you run it in compatibility mode as windows7, then it tries to go fullscreen, but windows borders remain all around the area,
see here -

I start skyrim with skse_loader.exe, if that makes any difference,
I've tried many versions, v6.3M1 doesn't seem to have a problem, but it's useless for me, I need 7 for my usb docking station (all 7.x versions are blocking nvidia renderer)
edit: problem is only when you run the game fullscreen - which is usually desired
