Issue reproduced positively on V560TU, display driver version update from 32.0.101.6129 to 32.0.101.6078, Windows Update display driver change to 6078 triggered only after EC ROM update. After power cycle, machine is usable again, with driver version 32.0.101.6078. I didn't saw "not working properly" device status of display adaptor at any point.

Weird, I don't think EC FW should impact this in any way

So not entirely reproduced as described in the issue, if I understand correctly? @wessel-novacustom do you have any more info on the device manager error?

Correct.
