I currently have a setup where I am using three screens across two dual-monitor, Windows 7 machines. One of the monitors (ViewSonic VG2030WM) is shared across both machines via dual inputs. I use Synergy to share a keyboard and mouse between the machines, but I have to manually switch the monitor when I toggle between machines.

Are there any utilities/tools to switch the inputs on the shared monitor?

I have not had any luck finding any such thing.

Just a quick thought, you may be able to utilize the presentation mode toggle.

press windows key + P and switch to either "projector only" or "computer only" and maybe the monitor will then pick up the remaining active video feed from the other computer.

I don't really have a way to test this but its worth a shot!


mControl seems to do this (if you're still looking for it), I'm evaluating it at the moment for the same thing and seems to work.

  • mControl doesn't seem to exist anymore on the website. – AntonioCS Jan 3 '16 at 12:45

There are KVM switches available with software controlled switching, but your best bet would probably just be to use RemoteDesktop, assuming they are both PCs
