The recent ATI drivers have support for choosing your own pixel color space setting...

"ATI Pixel Format".

As seen here;
ATI Pixel Format - AVS Forum

Have anyone tried messing about with these settings ?
At what were ur results ?

I guess your TV has to support multiple color spaces in order to have this setting present.

Seems like "rgb limited" gives me the best results here.
When using 25hz 1080p characters on my desktop had shadows and were uneasy on the eye.
Then I chose rgb limited..bingo gone.
The initial setting was 4:4:2 I think.

Yes, I've senn this as well (was present already in 8.12 I think), however there was a bug that the fromat you choose did not stick when rebooting. But it seems in the Release notes that it may well be fixed in 9.2?

Have you tried rebooting to see if the setting stays?
I've tried with 9.1 and it doesn't.

For me 4:4:2 works best (when I tested).

This was originally introduced in the 8.11 release back in late 2008.

Here is my thread over at AVS Forums regarding this feature. My Radeon X1900XT doesn't support this feature, thus I've had to use the brightness to 16 and contrast to 85 workaround.

But to summarise, the limited RGB (RGB 4:4:4) setting is what most people should be using, as most TV's accept a limited RGB (16 - 235) colour spectrum. Full RGB (0 - 255) tends to only be supported by monitors.

You will need to use the USEBT601CSC fix so that SD video is not affected negatively.

For anyone that are unsure, check you TV manuals or AVS for your brand of TV. I found out a few weeks ago that my HDTV support full RGB values through DVI/HDMI using a setting called "HDMI Black Level". It's a very ambiguous option - since your only choices are "normal" and "low". Switching it to low removes the RGB colour range compression and supports the full 0 - 255 gamut.
