Far-fetched problem (GPU or monitor?)

[Pawnless Endgame]

This is odd!

See in my video in what my Viewsonic 2030 does for most of the time.

Is it the GPU? - I have spotted a pattern that the display does this when I have certain windows maximised. If I restore my window to a partial-window, then the display remains constant.

Is it the monitor? - The monitor resets itself repeatedly. The green power LED even momentarily cuts when this happens.

Those are my arguments for either the GPU or the monitor. What do you guys think? Granted, the monitor was £400 new when I bought from OcUK and it's not the price that bothers me but the fact that it is 4:3 1600x1200 and 20". Being 1-eyed, you guys will appreciate that this is a necessity for me as 1-eyed bats adjust better to 4:3 than 16:9.

P.S. I have also tried it with an older Viewsonic 19" and it behaves ok regardless, so I'm leaning towards a monitor fault at the moment. It just puzzles me that my 20" Viewsonic is temperamental only in certain scenarios that suggests GPU/software problems.

Thanks.

Do u have more than one connection on your monitor, as iv got this problem with my monitor. It works great with VGA & HDMI but has the same problem you are getting if I use DVI

If it's a problem with the graphics card, would the monitor not go into stand-by mode when it loses signal? The fact it cuts power completely makes it look almost certainly to do with the monitor.

I'm confused about what you mentioned with the certain windows thing causing this problem, that is truly odd. Driver issue maybe?

I am using DVI.

It's certainly an odd one that only full (maximised) windows trigger the problem, but I have tried various drivers (ATI HD 4850). Because my smaller Viewsonic 19" monitor behaves 100% ok though, I'm pretty sure that it's the larger 20" monitor that is at fault. Thanks a lot for the input though

Granted, 1920x1080 is too wide for me, so I may be hunting for a 1920x1200 on OcUk next!
