My computer has been updating from Windows 7 to Windows 10 (several updates with that), and now my 2nd monitor (I use two) is dark blue and has a floating error message, "Input Not Supported". This is a newly built computer, although the monitors are not new. Both monitors worked at first (with new computer), but the one that's NOT working now had the fonts very big, as if set at a very low resolution. When I tried to put it at the "recommended setting" of 1024 X 768, it went dark blue on me and started saying "Input not Supported". Even though I've tried to change it back to the LOWEST resolution, restarted computer, etc., the error message won't go away - and I can't use the monitor. Help??
