Hey all

The most recent version of the PS3 firmware now allows you to change the RGB setting from "limited 15-235" to full 0-255". Apparently this allows your TV (if its supported) to display blacker than blacks and whiter than whites.

My display (a 42" 1080p from Avia) looks much better with this setting on. My question is this:

My TV was calibrated using the "limited" setting - now that the "full" setting is available, do I need to re-calibrate everything based on the new settings? Or do we calibrate for the limited setting?


Heres the information on the change:

Thanks!

You want to avoid full, and stay with limit for accurate video levels.

See Stacey's post here: http://www.avsforum.com/avs-vb/showthread.php?p=10630977&&#post10630977

So I just tested RGB @ full and you want to leave it as limit, unless you like to increase banding.

RGB @ Limit - Levels stay where they are. Y 1, CbCr 128 will be RGB 1, 1, 1 when done.
RGB @ Full - Levels get compressed. Y 1, CbCr 128 will be RGB 16, 16, 16 when done. (Best guess based on looking at image)
Full is different than the usual expansion where Y 16, CbCr 128 becomes RGB 0, 0, 0.

The best video quality is:

Output - YCbCr
RGB - Limit
Super White - On

BTB is still passed when RGB is set to limit, just bring brightness up to see it. Then turn brightness back down where it belongs. When you set brightness based on RGB limit and then switch to RGB full, you will see the BTB stripe. This is because you just remapped Y 7, CbCr 128 (the BTB stripe) to a much higher value.

Obviously if you were to change, you would need to calibrate, but you don't want to change to full.

For my projector RGB Full looked MUCH better, better blacks, and a better colorspace.

I'd say try both and see which one you like better:

RGB Full Range (HDMI)
[RGB Full Range (HDMI)] has been added as an option in (Display Settings) under (Settings).

If [Full] is set when using a TV that supports RGB full range, the picture quality of the game or video may be improved.

Limited RGB output signal is output in the range from 16 to 235.
Full RGB output signal is output in the range from 0 to 255.


Notes:If black sometimes appears bright and sometimes appears pale on the screen when [Limited] is selected, set this option to [Full].
If black appears dull on the screen when [Full] is selected, set this option to [Limited].
This setting can be used only when [HDMI] has been selected in [Video Output Settings] under (Settings) >
(Display Settings).

Y Pb/Cb Pr/Cr Super-White (HDMI)
[Y Pb/Cb Pr/Cr Super-White (HDMI)] has been added as an option in (Display Settings) under (Settings).

Super-white signal can now be output when playing Blu-ray Discs (BDs), DVDs or AVCHD discs.

Off Disable super-white output.
On Enable super-white output.

Notes
If image quality is reduced or if the image does not look right when this option is set to [On], set to [Off].
This setting can be used only when [HDMI] has been selected in [Video Output Settings] under (Settings) >
(Display Settings). Also, [Automatic]* or [Y Pb/Cb Pr/Cr] must be selected in [BD/DVD Video Output Format (HDMI)] under (Settings) > (BD/DVD Settings).
* The TV in use must support Y Pb/Cb Pr/Cr input signals.
About x.v.Color
When [Y Pb/Cb Pr/Cr Super-White (HDMI)] is set to [On], video content from AVCHD discs recorded in x.v.Color can be played with a wide color scale.

Notes
A TV that is compatible with x.v.Color (xvYCC) must be connected using an HDMI cable.
An AVCHD disc that was recorded in x.v.Color must be used.
The x.v.Color logo can be found on devices that support "xvYCC," which is an international standard for color space in moving images. An advantage of x.v.Color is that it can reproduce a wider color scale than the conventional standard.

In what way did it look better and how did you ascertain this factually? Did you recalibrate?
