Before I got a widescreen LCD for use with my x360, I was using a switch with my CRT monitor to switch between PC and x360. The switch I got was a cheap one (less than RM30) that only has video switching as opposed to keyboard/video/mouse on a KVM. I almost bought a KVM switch but realised I'll be paying extra for the mouse/keyboard switching for nothing. Anyway, either a video switch or a KVM switch, both will work.
