I have a dual display system. the computer is an Acer running Vista Home prmium. the displays are an HP 52031 and 20wm.
the videro outputs from the computer are 1 VGA and 1 HDMI. THe HDMI is connected to the display through a HDMAI/DVI adaptor.
Everything was working fine untill I had to move the computer system. Hooking it back up only one display would work.
I tried switching the cables between monitors. THe VGA connect was always the one that worked. At first if I unplugged the HDMI cable the monitor would display a message saying to check the cable, which I found encouraging, but now it won't even do that
THe diplay adaptor is NVidiia. I tried their utility to add a 2nd onitor with no luck. THeir autodetect would not see the other monitor.
I am sure it's a simple fix, but I can't figure out what to do.
thanks in advance
