Try a different monitor. turning a monitor on and off has no effect on anything other than the monitor. so the fact doing so temporarily fixes the issue, therss a vert high chance that its caused the issue.

hmm could be hdmi? its any diffrence betwen hdmi and VGA?

no DVI

 

[badger906]

well hdmi and dvi are digital signals where as vga is analogue.

basically you tend to get a sharper better picture with dvi/hdmi than you do with vga on a tft monitor as theyre digital themselves.

I also believe vga has a max resolution of something like 2600x1600, as back in the CRT days some monitors with very high resolutions required 2 signal inputs via vga
