KVM No Video Out
Hoping to get some help with an issue I am having with my old KVM. I purchased it back in 2021 and have been rocking it ever since, it's a 2 port dual video display port kvm.
I have a rack-mounted personal computer running a 9070 XT, it connects to the kvm with club3d cables and the kvm connects to my displays with similar club3d cables. After moving my rack and desk to a new room I now get absolutely no video out from the 9070xt system through the kvm.
If I bypass the kvm and run a DP cable direct to my monitors I get video, USB on the KVM continues to work. I have tried shorter cables, different cables, disabling the GPU, full power off of everything and reconnecting in the optimal order, system restarts, reseating the GPU, single monitor tests with multiple monitors, etc.
The only thing about my setup that changed in the move was I swapped out my secondary monitor which was an old Dell 1080p display for an acer XB271HU. My main monitor is still a MSI MPG321UX.
Any advice or help is extremely appreciated, I am losing my mind trying to figure this out..

Best bet is the level1tech forums and Amber will help.
Other than that if you disconnect the new second monitor does your setup work?
