Ok, so I was in my school server room a while ago, and for the 5 servers they have, they only use one monitor. What they have is like a box with numbered buttons on the top and you plug a VGA cable into each one from the computer, then from the box into a monitor. So if system One is plugged into number one and you press number one, number one displays on the monitor. I hope you understand what I mean, but does anyone know what these are called and where I can buy one? In the UK if possible, but at least a name would be nice. Cheers.
