How to make two laptops share the same external monitor?
I have two laptops which I need to connect (one at the time of course) to the same external high-resolution LCD monitor (Dell Ultrasharp 21") in 1600x1200 mode. I tried a hardware switch from my local computer store (2-in, 1-out), but I get ghost reflections. I need some kind of high-quality switch as this monitor is used for photography processing and I definitely don't want any ghost image.
