I found the problem; I had to change the actual monitor resolution by changing the Adapter Properties' "List all modes" pull down menu from the display settings and Display adapter properties link. ...

just 1 gpu with drivers updated, uninstalled, reinstalled x7 or more times with different driver versions dating back close to 2 years till present, main is hdmi, 20" is dvi-d

I have two screens; The main one I use is a 47" 1080p tv. The other one is a 20.1" 1680x1050 max monitor which I use in another room which is used a few times a week.
For some reason, I can't seem...
