Vista - wavey screen flickering when looking at dark pictures/games

**rockstar6181** · 03-30-2009

I have noticed that my monitor has wavey type lines moving up and down (almost like interference)...I seem to get it most when the screen is dark or when loading up a game...for example I loaded up Crysis, Grid, R6V2 and all on the intro screens looked like the screen picture was split in half and you could see the join line..I have tried playing around with the res and refresh rates but not having much luck..got a 22" montior and a 8800GTX graphics card - all drivers are up to date.

Is it only happening in games, or is at the desktop as well?

How old is the monitor?

Have you enabled/forced VSYNC?

**RestlessShadow** · 03-30-2009

Also, how long have you had the card, and have you used it a lot?

Thanks for replys.

Monitor is about 12 months old - 22" TFT Asus VM202 i think

Graphics card was bought about a year ago too at same time - i noticed the waveryness first on the windows sidebar when i had a black background. I turned the sidebar off and didnt notice it again till i started playing games recently.

In game it doesnt really do it, its mostly when loading up the game and all the ads are coming up etc - the screen alomost looks like its joined together and slightly out of sync with the bottom to top half.

I will check VSYNC tonight. I also use a VGA to DVI convertor. but will try straight DVI.

Checking the straight DVI connection is a good idea. Connections and cables are known culprits.

Does both the monitors menu / OSD and Windows / Nvidia control panel report report the refresh rate @ 60hz when it's at 1680x1050?

Do you recall updating any drivers around the time it started to waver?

When you notice the waver, does cycling through the inputs fix it?

yeah at that res (1680x1050) the refresh rate will only allow max of 60hz.

Havent managed to borrow the DVI lead for this evening but should get it shortly..do have another tft monitor I will try later on tonight.

many thanks
