Is this monitor intended as a 2nd monitor, or as the primary monitor between two computers?
Usually KVMs are used to connect two computers to one monitor, but you only mentioned one OS, XP.
Does the monitor work on the computer, (or computers), if it is wired directly?
I fished out my old IOGEAR KVM from storage and it did'nt register on my monitor. The roaming NO SIGNAL message goes away when I attach it but just a black screen. Thinking it was old and broken I bought a new Trendnet KVM and the very same thing. The monitor know something is hooked up to it but no picture display. Chances both KVMs are toast is highly unlikely. Monitor fine when I connect directly to my PC. Please...am I missing something obvious? Same PC I have always had and the only difference is the flat panal.
