Yes the system that this is occurring with is a Windows 7 Box, Threadripper 1920x, Asrock Fatal1ty x399 Board and a Gigabyte RX550. I know Windows 7 on Threadripper is a little unorthodox, but I would like to duel boot the box in the future with a linux distro and avoid the upgrade(downgrade) to Windows 10
Moving the mouse and hammering the keyboard do not wake it back up. I have not tried switching boxes on the KVM while it was booting or in UEFI. The problem, as I know it, is only after being fully booted.
I have tried switching back and forth a few times and no dice. I’ve used both the hardware switches on the KVM as well as the hotkeys too. I’ve also tried unplugging the DP cable and re-plugging it in and also nothing. One weird caveat is that I have had it work successfully once or twice, but only after an extended period of time before switching back to the box.
The other box I have is also a Windows 7 Box with an RX480 in it and Haven’t had any problems bringing that box up on the KVM switch.
My cable length is 10ft, however, I have zero problems when not using the KVM and never had any artifact issues or display corruption.
I’m gunna have look at the driver situation and make sure that everything is working there before anything else.
