The Belkin OmniCube 4-port KVM switch box is a rather small device. The 4-port switch allows you to hook up a max of 4 computer. Setup couldn't be simpler. Start your computer, and assuming you have the correct port selected, you should be able to work on your computer as if nothing has changed. Repeat for all your computers.
Video is good.
Personally, I cannot tell any difference between the image quality now and when I'm hooked up directly to the computer. The quickest way of selection which computer to control is to use the hot-key combo. This is where the Belkin product has its strong and weak points. On the positive side, it does not use the CTRL button like other models. Instead it uses the Scroll Lock button.
