A KVM switch, standing for Keyboard, Video (or Visual display unit) and Mouse, is a piece of hardware that allows a user to control multiple different computers from a single set of peripherals (although some KVM can also allow for the opposite). Sometimes also known as a monitor switch box, KVM switches allow you to perform different tasks on different PCs simultaneously, for example listening to music on one machine while working - or gaming - on another, and cut out time wasted fumbling around with cables to swap around pieces of hardware manually. Here at Novatech we stock everything you need for a multiple PC setup, and with our speedy delivery service your 4 port KVM switch will be with you before you know it.
