This board is using the onboard x1240 ATI card to output to my panasoni Veira 42 inch plasma. I have configured it the same as my last HTPC which I upgraded from. Upscaling to 1920 x 1080 via the FFDshow resize options.

The picture quality is not as good as it was will my lat htpc which was a Nvidia based card. There must be some suggested settings or configuration that I can use to improve the output quality. I have it outputting 1080i to my Plamsa, but the picture should be more sharp that it is.

Any advice?

1. What resolution and refresh rates are used?
2. What decoder is used?

What is the full type description of the plasma?
I also have a 42'' Panasonic Plasma (PV7F).
The Panel has a native resolution of 1024*720.
So i suppose you are upscaling far too high.
I use a NVIDIA 8500 based video card which produces a very nice picture.
It's connected via a DVI to HDMI cable and i use no up-/downscaling in ffdshow at all.
The Windows XP screen resolution is set to 720p and only had to adjust the screen size a bit.
It works really great with the NVIDIA pure video codec

Not sure what model Panasonic it is but I will check today to see what res it can support. Using FFDshow codecs from within media portal to output everything.

Thanks

Hi,


My pixels are the same as your panasonic. However setting it to 720P did not improve the quality as I would expect. Apprears the sharpness of videos isn't on par with the Nvidia cards. Maybe it's still a configuration issue, the edges appear ghosted on images and not sharp.

I have calibrated my plasma using test screens and it has not inpact on the video output quality. I would guess that hardware accelearation is not used or something!
