Review on 🔁 Tendak 4K HDMI KVM Switch: 4 in 1 Out, Keyboard Mouse Printer Switcher, 4 USB Type-B Cables, 4K@60Hz, EDID/HDCP 2.2, 3D - Ideal for Laptop PS4 Xbox one HDTV Monitor by Darius Carraway

Setup was quick and easy. Works as advertised. A few notes: 1) It looks like this device can also be powered via HDMI and/or USB. The power adapter is great, but I don't even use it. I think it is cool. 2) I have 3 Raspberry Pi 4 devices connected and as soon as the screen expires on the Pi, the KVM does not pass any HDMI signal from it when it wakes up. It turns out that the problem is not with KVM, but with some settings that need to be changed/uncommented in /boot/config.txt: hdmi_force_hotplug=1hdmi_drive=2 Install them, reboot the Pi and everything will be fine . At least it was for me. Definitely yes, buy the thing. It works, it's small and the price is good.
