9800 S-Video vs Composite quality issue


Tony DiMarzio

I am experiencing a problem with my 9800 pro. Using the ATI provided
S-Video to Composite adapter, which has more pins at the S-Video end than
I've seen on normal S-Video Connectors, in conjunction with an expensive and
high-quality composite video cable, I achieve much better image quality to
the TV than with an expensive( $50.00 10ft) and high-quality S-Video cable.
Does not make any sense. The video quality should be noticeably better with
the S-Video, but in this case it is the other way around. HOWEVER!! If I use
the ATI-Provided S-Video cable the picture quality is perfect. Problem with
that is that the cable is only 3 feet, which is wayyyy to short for where my
TV is. Use the ATI-provided, short S-Video cable and everything is fine.
Use a $50 double shielded gold plated S-Video cable that is 4 meters and the
picture sucks.

Anyone experience this or have any ideas?

The S-Video quality problem mentioned above is quite noticeable with almost
a checkered pattern overlain on the TV. I tried two separate S-Video cables
besides the ATI provided cable. They both did the same thing.


u guys have used the 'advanced' features in display properties....focus sharpness color etc?

Of course! Have tried tweaking every setting that exists in the ATI control
panel. All things being equal... I achieve considerably better quality with
a 12ft composite cable hooked into the ATI S-Video to composite adapter than
I do with a very high quality 12ft S-Video cable. However, and like I've
said, using the supplied 3ft ATI S-Video cable the picture quality is great.
makes no sense. I'm hoping that ATI doesn't have some proprietary liking to
only certain S-Video cables, but right now that seems the only explanation.

so have you reverted to using a composite cable instead? I have because
right now I have no other choice.
