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.
