The only well-reviewed DisplayPort KVMs I'm aware of are from Level1Techs: https://www.store.level1techs.com/products/kvm

Not cheap though. And also not 100% caveat-free.

And even those still require a https://www.store.level1techs.com/products/p/dp-repeater-hdm... per port to make it so the computer doesn't detect the monitor switching away.

I have a Level1Techs hdmi KVM and it's awesome, and I'd totally buy a display port one once it has built in EDID cloners, but even at their super premium price point, it's just not something they're willing to do yet.

I have Linux (AMD RDNA2), Windows (NVIDIA Ada), and Mac (M3) systems hooked up to my L1T DP1.4 KVM[1] without any other gadgets and they all work fine. What problem(s) are you trying to solve/did you solve with the EDID cloner?

Without the EDID cloner, when you switch the KVM away from the system, it receives a monitor disconnect event. When you switch it back, it receives a monitor connect event. There are OS settings that help make it so that the windows end up back where they started, but not all programs support this well. With a EDID cloner in place, the computer never detects that the monitor shifted at all and so nothing gets repositioned and apps just carry on.

I have one and it still sucks. I ordered it after the one I bought on Amazon kind of sucked thinking the L1T would be better and it was worse than the Amazon one.

Say more?
