The past week the bottom 10-15% of my screen started to flicker on occasion. Been running Win7 since it came out, Monitor is probably 8yrs old (Samsung 2232BW), video card I got early this year so under a year old. Checked and made sure everything is connected properly.

I have my TV plugged into the same card and when both running not seeing the flicker so thinking the screen itself... when a screen starts to go, is that a common symptom? or should I check something else?

Been playing around with settings... noticed that the more detail a background image has the more it flickers, and depending where the details are, affects where it flickers so not just the bottom 15%.

Been turning on/off aero which doesn't seem to make much difference, it's mostly the background image itself that does.

Running stress tests with various programs I found online... some good some bad... but none giving any errors.

Will grab the 19" Dell tomorrow and give it a test. Will need to find another DVI cable though to test that with... can't recall if the other computer here is DVI or using VGA still.

I also updated the video card drivers today.

If still flickers on the other screen and with another cable... I guess it's narrowed down to video card or software. At which point I format the C:\ and reinstall everything I guess. If still an issue... I guess video card despite the lack of error messages from stress tests?

Try integrated graphics if you have it.

Good suggestion.

Right now, I took the LCD off the family computer and switched. Problem is, their LCD on my system is fine, my LCD on their system is fine.

Ordered a couple new DVI cables, found them on sale cheap. Their system is still using VGA so may be it's a DVI port or digital issue, regardless, they need a better cable. Other downside is mine is 1680x1050 and theirs is 1440x900, so, maybe it's a video card issue still just that at a lower resolution the card isn't working quite as hard so not failing.

Gotta hate the cases that are less than straight forward. Admittedly, if there is an issue I am hoping monitor... I'm due for a better one, like the DELL Ultrasharp U2414H.
