My mid-range LG monitor has a built in KVM as well as PBP (picture by picture??) --- Whatever it stands for, I am able to split my 34 inch wide screen between my work Macbook and my personal computer (Linux) - I use an app that I've had forever called Synergy to share my mouse and keyboard between them seamlessly. You can even copy/paste across machines. I personally am hooked on my PBP widescreen+Synergy combo.
