The games definitely will look better on RGB full, you just need to calibrate your TV.
Games running on my Panasonic plasma looked dark but I have switched to ECO picture mode and loaded calibration video on ps3(video download http://www.filejumbo.com/Download/AB091EEF36A015F8 ) to calibrate contrast, brightness and other parameters and now my games looks SuperB and no black crush as someone referring here.

Please keep in mind I am no expert, but based on what you say I would hazard a guess towards yes. However, if you have to modify your television colour settings into some weird place to make all twelve show, it’s probably not really designed with the RGB Full/HDMI in mind. What matters most in the end is how good the picture on the screen looks. No matter how it is being achieved.

I want to ask you a question? First when i set limited RGB, my tv can display all 12 rectangles. Then after i changed to full RGB, my tv can only display 9 rectangles with max brightness. So i try to reduce my tv contrast by 15, the result is I can see all 12 rectangles agan (even though not as clear as in limited). So my question is whether my TV support the full RGB?

Well, thank you. I’m glad it helped. I dislike seeing bad information out there on forums and with luck this helps start clearing some up (I intend to write more but have no topics in mind right now).

Keep in mind however these are simply my own conclusions drawn from information I can find, as someone previously commented I have probably missed some info on the whole Y PB/CB Pr/Cr topic – but I was not aiming for that at the time.

Well done. I’ve spent the better part of two weeks since discovering this function on the PS3 trying to understand exactly what it does and if my TV supports it (BTW – don’t bother calling the TV maker and asking their technical support people, they will have NO idea). This article takes a straight-forward and simple approach to a not-so-simple interaction between the PS3 and HDTV.

I love all the functionality of the PS3 but I sometimes feel like they intentionally don’t explain this as well as they could because it shows how not all HDTV signal is equal; one mans 1080p is another mans 720p (if you need an example try figuring out why the PS3 doesnt output Dolby TREUHD or DTS HDMA).

This is a solid, well thought out effort, and one that is very much appreciated.

That is interesting, although I think I might of made that point (accidentally perhaps) in the examples where I showed RGB Full, Limited and Y PB/CB Pr/Cr. I was reading into that topic at the time but have not since gone back, not much need to so far. I do however recall that you can have these settings separately, as optical disc based playback on my PS3 defaults to Y PB/CB Pr/Cr where games default to RGB Limited, it appears to be kept in separate config.

Thanks for pointing this out though, I’ll try and stop being lazy, read more and update it. For now, people can see it in your comment.

Your analysis is mostly correct, however you need to make sure the media also supports RGB full and not just the hardware. RGB full will never look good for movies because movies are coded for video levels(16-235) as opposed to games which are coded for PC levels(0-255) but since games graphics can be created on the fly they can use either PC or video levels. So for movies the choice is to use RGB limited or use Y PB/CB Pr/Cr(which is what I use) and for games use RGB Full(if your tv supports it). Movies played in RGB full will have severe black crush.

Hey there, thanks for giving some feedback. The pre-sets that come with your TV are often not the best for actual home use and I highly recommend you look into tuning an HD TV for your environment. It’s actually not hard, just takes some research and a bit of time.

I gather it is not a Sony from the pre-set names (I only have a Bravia to test) but I would assume Dynamic is similar to Vivid on a Sony set which probably makes the colours stand out really brightly, and if that is the case then you can be sure it is not a good setting to use at home because it is designed to catch the eye in a brightly lit shop rather than reproduce accurate colour.

The Movie setting is typically much darker and configured to give a more realistic colour reproduction for film and if you can see all the blocks on that setting then I would have to assume your TV does indeed support Full Range RGB over HDMI and the best thing for you to do next would be to tune the TV under the Custom slot.

Although this will not be the ultimate guide it looks like a good point to start your research:

Hi! very interesting article. I tested on my TV and I’m not sure if RGB full is supported or not.

I did the following: I download the image and set FULL. At first, I saw nothing. Then I changed the PICTURE MODE from DYNAMIC to STANDARD. Nothing… switched to CUSTOM and nothing. Finally, I switched MOVIE and I saw all the blocks.

On RGB FULL colors seems more ‘intense’ but except for the MOVIE MODE, in the rest, the darker areas are BLACK.
