Review on CKL HDMI KVM Switch 2 Port Dual Monitor 4K 60Hz with Audio, 2x2 PC Monitor Keyboard Mouse Selector and 2 USB 2.0 HUB (Model: CKL-922HUA-2) by David Bott

Good 2-port HDMI KVM. The display quality is excellent. I am using a Logitech wireless keyboard/mouse with its merging receiver and have had issues where if the hotkey was on the keyboard it would intermittently have sticky key behavior on both computers (e.g. highlighting text on the screen etc. ) would show. I "solved" this by disabling the hotkey feature on the front of the switch, which means I have to use the physical buttons to switch devices. Also, for some reason, this setting doesn't wake up any of the machines. But overall it works for my purposes and I'm happy with the purchase.
