I was doing some cleaning under my desk and cable management.
I unplugged my monitor DVI cables to untangle the wires and literally plugged them back in within 15 seconds.
One of the monitors don't work now and is giving me a "No Signal"
As well, all my icons squeezed over to just the one working monitor now.
I've had these monitors for about 4 years now and never had any sort of problem like this before.
Further testing, I tried swapping the DVI cables, plugging them in the different ports of my video card, rebooting the computer, etc,
Seems like whichever monitor I plug in first (with either cables or either ports),
will become my primary, and the second monitor will just refuse to post a signal.
But both monitors and both DVI cables are working fine it seems... just won't work together at the same time...
Is this some kind of setting with my video card??
I went into my display settings and only one monitor is being detected.
