Windows 7: Problems with 2nd Display

Problems with 2nd Display

Hi,

a few weeks ago (with windows xp) I was using both my 17" and 24" monitors from dell, and all of a sudden the 2nd display stopped working (it appears to not be receiving a connection from my computer) I then updated all my drivers, and checked if there was any monitor drivers needed (nope).

when I switch my monitors, whichever is plugged in the right outlet works (therefore eliminating whether or not the cables/monitor is not functioning)

I did some internetting and the only solution that semi worked was:

1. unplug all power and dvi cables from bothe the monitors and the computer
2. wait a while
3. replug, and boot up

with this, both monitor would work up until the windows xp loading screen, after windows loaded the 2nd monitor would fail to receive a signal (so I do not think its the port on my video card)

Yesterday I had some time, so I installed my copy of windows 7, and all drivers and such.

fortunately both my monitors worked, until I was stupid enough to physically rearrange them (I wanted the bigger monitor to be on the other side), while doing this the monitor cable got unplugged and I had lost my 2nd monitor, again.

so I did the ol' unplug everything and wait some time trick.

and it worked! (thus i know its definitely not my video card), I went to sleep watching some TV shows on it.

when I woke up my computer was asleep, upon resuming activity on my computer, my 2nd monitor failed to be detected once again.

when I go to my nvidia options or the display options the 2nd monitor is not detected, therefore I cant extend my desktop to it or acknowledge it any way.

I think if I unplug everything and wait some time, it may temporarily fix the problem, but I really don't want to keep doing that (i notice it takes atleast 30 minutes of it being unplugged to revert back to functioning)

so.. does anyone have any suggestions?

Well, do you have warranty on the system, or on the GPU? It seems that one port has been broken. You can also try to switch the card to another pci-port.
Good luck.

Nope no warranty

I will be testing it with a functioning GPU soon, but I still am not 100% sure its the gpu. It was functioning effectively just before the computer went to sleep. But ill tinker around with it and see if I get anywhere.

thanks!

not a real solution, but Ill live with it for now:

I changed the one of the monitors to a VGA cable instead of a DVI cable (although it is still plugged into a DVI port, but with a converter) and it seems to be working now

anyone know what this means? and if I will be able to go back to DVI?
