Hi,

I have a problem that I think has to do with the DDR 128 ATI Radeon
9800 Pro card in my 5 year old system (Dell Dimension 8200, XP Pro
SP2, 1.25 GB RAM).

When playing DVDs or video files there are vertical lines spaced about
1/2" apart of what look like alternating 1/4" wide red and green jelly
beans. If I reduce the viewing area to about 1" h x 2" w they
accordingly shrink and then eventually disappear; not an optimal
solution.

Any other program displays fine across the whole viewing screen of a
22" Mitsubishi Diamond Pro 2070 at 1280 x 1024 @ 75 Hz. I have
reinstalled the drivers, tied different resolutions and refresh rates,
taken the card out and cleaned the contacts and slot. Physically the
card looks fine, the fan works, etc.

After putting the card back in for a short while the viewing of movies
was fine but I suppose as the card warmed the same problem came back.
My guess is that one of its chips dedicated to processing video has
bit the dust and I need to get a replacement card. Other than video
related programs the display is fine.

Thanks for your help everyone, Steve.

Codec problems can give similar banding of colour on some movie files
- it might be worth trying something like VLC (videolan.org) before
you scrap it :-}

Any player I use has the same problem - Media Player 10, MP Classic,
VLC.

Are you sure your children weren't playing with your monitor while
eating Easter candy?
