Review on CKL-94H: 4 Port USB HDMI KVM Switch with Auto Scan | Supports 1080P 3D, EDID & Cable Kits | Ideal for PC, Server, DVR, NVR, Game Consoles (Xbox, PS3, PS4) | Convenient Monitor Keyboard Mouse Switcher by Richard Cunningham

Easy to install and use. I like that the LED of the port you are connected to is orange and the other port is green when the PC is on and off when the PC is off/unconnected. (Although I'd swap the colors.) I wasn't able to use my existing (wired) optical mouse, although this may be due to the fact that the keyboard and mouse on my desk are not connected directly, but via a 2-port USB connector. Hub (no way to run a cable to a KVM switch without interfering with the keyboard tray). My old VGA KVM switch had no problem with it, but this one doesn't seem to like it. At the moment I'm using a wireless mouse with the dongle plugged into the USB port of the KVM switch and it works fine. I use a wireless mouse away from my desk, so I'm hoping I can find another mouse that works with this setup so I don't have to unplug the dongle every time I work away from my desk.
