Review on TreasLin HDMI KVM Switch: Seamless 4K@30 4:4:4, Picture-in-Picture Control, OSD, Drag & Drop Window, Multi-Viewing by Doug Bunkers

I was pleasantly surprised when my Logitech wireless keyboard and mouse combo worked with this KVM. I know some wireless keyboards/mice don't work. During setup I tried a few different mice and keyboards. It seems that if you change them, computers stop recognizing them. I did some googling and found the answer right here on the Revain product page: use the hotkey combination * + F11 to "reset" the keyboard and mouse. This worked well for me and found that I need to use it whenever I switch keyboards and/or mice. Another slight learning curve is that when using hotkeys to switch screens, you have to use the number keys on the number pad. First I used other number keys and they didn't work. The only thing I don't like is that my monitor doesn't seem to go to sleep even when the currently active computer stops sending it a signal. Maybe there is a solution for this that I haven't discovered yet. I've only been using it for a few days but so far so good.
