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 Robert Lewis

I am using this with a 27" x 27" monitor to connect 4 computers to a set of peripherals. Excellent quality. The small rubberized remote sits perfectly on my desk and switching between computers works exactly as intended. From time to time the switch will default to input 1, but it's as simple as pressing a button to switch back to the desired input. 30Hz is great for my workflow as I work at 29.97 fps most of the time. It was great going from dual monitors and a bunch of peripherals that I had to constantly disconnect to a clean desktop. Highly recommended. Lots of cables so ditch the zip ties and with a bit of fiddling you'll have a better setup than you have now.
