One of my KVMs keeps having issues on both DP and USB.
All the USB ports stop working and my primary display (connected to port 2) gets disconnected a lot. It didn’t do this in the past, but started doing it about a month ago.
I was having issues with HDR where it would sometimes have some white specs. I used to see this with my VR headset years ago if the connection wasn’t good. It’s DisplayPort signal noise as far as I understand it (yes, even though it’s digital).
So I thought maybe it was because of the KabelDireck DP cables, but switching to Club3D, it was much worse; unusable with lots of artifacts.
I’m wondering now if it’s actually the KVM causing the issues and that the USB controller is getting nix’d because of DP issues.
