Pros: Came complete with cables, some of these switches don't. It worked with my monitor: Acer RT280K bmjdpx 28" 3840 x 2160 (4K) 1ms (GTG) 60 Hz DVI, HDMI, DisplayPort Built-in Speakers LED Monitor The first KVM switch I tried, which claimed to support 4K, did not work. This switch comes with a little button that you can put next to the keyboard, so the box and cables can be hidden, avoiding the cable clutter that you get with these things. I'm very happy.

Cons: I had no problems with this switch.

Overall Review: I have used 2-port and 4-port KVM switches for years. Some units don't switch, some don't work with the monitor, etc. I'm using this with a NUC running Linux and a high-end Windows 10 laptop connected to a high resolution ACER monditor. This unit works like it should.

Pros: Easy to install.

Cons: The network does not support ubuntu, only windows. You can install windows, but only the wireless will work and only on Ubuntu 18.

Overall Review: If you want an ubuntu OS, buy a different board.
