Review on 🖥️ TESmart HDMI KVM Switch 4 Port 4K@60Hz Ultra HD 4x1 + 2x 5ft KVM Cables | Keyboard & Mouse Pass Through | USB 2.0 Device Support (Black) by Jeff Ross

Works very well. Makes WFH's life so much easier by allowing you to switch between multiple computers with one click, using the same mouse, keyboard and screen. I initially noticed an intermittent dimming of the screens, which was very annoying, and I noticed that this only occurs with large movements on the screen. I realized I was using a lower quality HDMI cable that can't handle 4K @ 60Hz bandwidth to connect from the output of the switcher to the input of my monitor. I replaced the cable with a compatible 28AWG 4k@60hz cable and I never experienced dimming or flickering again. I deducted a point for not being able to resolve an issue where my Logitech wireless keyboard would sometimes hang when I pressed keys and it would type dddddddd or the last key I pressed. I solved the problem by not using the "Mouse and Keyboard" port, but by connecting my nano receiver to a USB hub connected to the switch's USB peripheral port . The downside to this is that I can't use the "Scrolllock + Scrolllock + 2" hotkey to switch to my second computers because the hotkey toggle only works when your keyboard is plugged into the mouse and keyboard port on the switch is.
