Review on TESmart Display Switcher Supports Devices by Eric Nelso

Nice attempt at a functional KVM. I had serious signal quality issues when the port was running at a frequency above 60Hz. NO EDID capability (I think they updated the description now). Mouse and keyboard input are virtually useless for anything but the most basic mouse and keyboard. They don't work with my mechanical Corsair CBDs, nor with any of my Logitec mice with programmable buttons or other features (in PASS or EXIT mode). However, I was able to get the mouse and keyboard working via the USB hub feature. Maybe others have better luck. I returned it and bought a TRENDnet TK-240DP which also has no EDID but works very reliably with one input at 2560x1440 at 144Hz and the other at 2560x1440 at 100Hz. So far there are no problems with the signal quality. I haven't tested the mouse and keyboard input yet, I'm just using the hub feature on this KVM. But at least the monitor stopped constantly blinking and flickering.
