Hi folks,


Having a bit of of a vexing problem. I've just installed a new TESmart 8port 4k KVM switch. When I move between 4k sources it's fine, but whenver I switch over to a non 4k source, windows acts like the monitor is briefly disconnected and tosses all of my windows on to a secondary monitor. It's as if the KVM is not properly spoofing the EDID and sending it back to the PC.


To further complicate matters, I have a second switcher in between the KVM and the PC acting as a signal booster. The signal from the PC isn't quite strong enough without it. Both devices should be spoofing the EDID back to the PC, but still I am having this problem.


Is there maybe a windows setting to fix this, or maybe some kind of dedicated EDID cloner that can just always tell the PC it has a 4K monitor attached?

It has been so long since I used a KVM, I really have no suggestion but to ensure drivers are updated. Sorry.
