I'll give that a shot as well, what difference will that make?

An LCD screen is digital. It only runs at say 1280x1024@60Hz. Feeding anything analogue into the screen takes processing-time (lag) and may cause misalignment of frames (for example if you play a 48hz game at 48hz over VGA, the LCD screen upscaler may get hiccups). So you get a clearer picture, no more errors, and less input-lag.

jrose, I don't believe it's losing focus, but I'll definitely check that.

Blanka, I'll definitley try out a dvi cable and see if that fixes the issue.

Thanks!

CWorley:
I checked on the resolution which is 1600x1200, the monitor's native res.

I also switched to a dvi cable.

There is still flickering with the screen.  It happens outside of Mame and Mala as well.

Any other ideas of what to try?  Really hoping the monitor is not failing.

Blanka:
Maybe the backlight is going nuts.
Check if the on screen menu works without any input signal. If that flickers, you're in trouble.

CWorley:
So the screen was fine for a while, then it started to flicker again. 

Here is a video of what it's doing:


Anybody have any ideas of what's wrong?

Thanks!
