RGB or Limited for PS3?

Sony 40w3000.

Are crushed blacks when the shadow detail is VERY dark, clearly noticeable compared to the same picture when using 'limited' RGB.

On my Sharp TV I find the PS3 XMB menu looks better with 'Full' RGB, the black background is very deep, with 'limited' RGB it looks a little greyish.

However when you look at a picture or game with 'Full' RGB, the shadow detail and general picture can be very dark.

For the BD settings I use Pb/Cb Pr/Cr, so the issue is only for games which use RGB.

yep thats correct, it will kill shadow detail and you will clip Below black info.
Dont set it to get a deeper black, that would be a mistake, as all your doing is setting incorrect video levels for your display.

again if you set the PS3 for RGB full, your display must either be set to RGB full or have an auto option that can correctly display RGB full.


Should also note if you set the display/TV for full RGB and then use Pb/Cb Pr/Cr it can throw a green vail to the image as the TV is forcing RGB full while the PS3 BD settings is trying to send Pb/Cb Pr/Cr. Now some TVs will handle this correctly others go into a head spin.

Any idea how the Sony XBR3s and XBR5s handle the RGB correctly because like the other person said the PS3 screen looks like a richer blacks and the movies seem to have an eye popping color, but I have to turn up the brightness otherwise the black is just too black. I will mess with my Sony tv settings tonight to see if that helps.

well the extra colour is just an eye trick as you have moved to incorrect video levels. the black looks better because its clipping any below black info. sadly an LCD display does not do a true black, so getting a deeper black is fooling you and is incorrect. you have to then raise brightness to again see the below black info that is being clipped by the Full RGB setting.
Dont adjust the RGB level just to see a better black on the PS3 desktop, your just incorrectly displaying video levels.

Whers DarinP when you need him.

My Sharp TV has HDMI input options for Pb/Cb Pr/Cr 4 4 4, Pb/Cb Pr/Cr 4 2 2 and RGB.

I set the TV to Pb/Cb Pr/Cr 4 2 2 and 'Dynamic range' normal for Blu-ray playback. BD settings on the PS3 are obviously Pb/Cb Pr/Cr.

For games I've decided to set the TV to RGB and 'Dynamic Range' normal. PS3 settings RGB limited.

Previously RGB Full gave me crushed blacks.

Re. the green veil if your TV and PS3 settings conflict, I found my TV to be fine, even when I left the TV's HDMI input as Pb/Cb Pr/Cr 4 4 2 and played games with RGB limited/Full, it sorted itself out.

From now on however I'll simply change the HDMI input from Pb/Cb Pr/Cr 4 2 2 or RGB for Blu-ray and games respectively, afterall it's only a quick and simple option change.

I have a 1080p Samsung HL-T5687s LED DLP. To me, RGB Full looks better than limited (I just changed it to Full when it was on limited, and my picture looks a little bit sharper I haven't played a game or watched a movie yet, so I am not sure if that will make a difference). Under Y Pb/Cb Pr/Cr Super-white (HDMI), my setting is off. Should that be changed?

Does anyone have any ideas as to what, if anything, I can do do tweak my picture and make it look a little bit better? Thanks!
