GTX 580 - Dual monitor setup - 2nd monitor stopped working overnight - No signal

post #1 of 4
Thread Starter 
My computer has been running fine. No issues what so ever.

I turn on my computer today, and my 2nd monitor is not getting a signal.

I have changed nothing on my system to cause this.

When I go into Nvidia Control Panel, it recognizes both monitors. But even if I switch the setup to only running the second monitor nothing happens. Still receives no signal.

Any ideas on what is going on?

There have been problems with problems with monitors that don't have built in scalers, especially the Korean monitors, when used in conjunction with the new nVidia drivers. Could that be it?

I am thinking it is the drivers, but not sure why.

I have used the same drivers for around 6 months now, and it was working 100% fine last night.

But I goto bed, wake up and its not working? Seems weird.

Could a virus cause issues with the drivers or connectivity of certain devices?(2nd Monitor)

Thanks

EDIT:

I am using a GTX 580 SC Video card, with 2 x Viewsonic VX2439wm monitors connected with DVI Cables.

EDIT:

The computer is displaying the 2nd monitor is connected through VGA. But its not, its using DVI.

EDIT:

I put the monitor on the first port on the video card.(The first port) It loads up displays the bios screen, shows the starting windows screen, then goes to no signal. So it doesn't seem to be a bad DVI port on the card.

Problem Solved.

Not sure what the cause or reason behind the issue. But I power cycled the monitor.(Unplugged it from the wall, held the power button for 30+sec). And its working again.

Thanks everyone for the help.
