I don’t get any kickbacks I swear. Check out MaxiVista it is truly a great product a number of people here use everyday. It is a simple client/server application that provides software based multi-monitor and KVM functionality.
…Really, I don’t have an affiliation with them what so ever. It is just a great product. If you bring a laptop to work like I do, it is a necessity. Instant KVM and Multimon without waiting for new hardware. Enjoy and please pay for it if you use it, they’ve earned it!
