Guest Bob Day Posted July 1, 2008 Posted July 1, 2008 Using Windows XP (latest updates), Dell Latitude D820 and View Sonic monitor… I have the VGA on the monitor connected to a KVM switch to view two different computers, this has always worked fine. The Dell laptop docking station has a DVI (in addition to VGA) and the View Sonic monitor has a DVI (in addition to a VGA). So, I thought if I hooked up the DVI, and left the VGA hooked up, it would simply be a matter of using the monitor's on screen input selector to choose Analog (vga) or Digital (dvi). However, when ever I choose DVI, it displays analog, as if there is nothing coming across on the DVI cable. Do you have to do something on the computer to have it display over the DVI? Anybody know what the problem might be? Thanks Bob

Some (but not all) will auto set to VGA whenever one is connected even if a DVI is also connected.
