PS3 RGB setting limited or full, what's best?

[BaeDaTruth]

i was messing around a little bit with the options while watching disturbia yesterday..and i went to AV settings, and switched it from automatic to RBG, and it made everything a little brighter, but i felt it also made the picture quality better as well...so for reference, i put on POTC, and it REALLY made a difference...can somebody school me real brief on this matter?

Well RGB should send the RGB values (like computers, you know to make grey RGB is R = 128, Green = 128, Blue = 128, while bclacks is R = 0 G = 0 B = 0 and white R = 255, G = 255, B = 255, and colors and grey tones any combination in between), while regular video is Ycc meaning Y = the combination of RGB in a certain proportion to make the black and white potrion of the image (called Luminance) and the ccs are smaller color components substracted from Y (for example R-Y and B -Y) (you can get green from all those) (Video is made that way to make it easier to "carry" and compress (reduce bandwith)).

But there's another thing. Computer RGB is from 0-255 while video RGB is from 16-235. So probably the change of brightness is due to the Ycc output being one way and the RGB being another. Before the latest firmware upgrades the PS3 RGB sent 16 as 16 and 235 as 235, now it has a new setting that sends 16 as 0 and 235 as 255, so you might play with that. (they're called Limited/Full in the settings , respectively)


btw I use the RGB output on my PS3

thanks..alot of that didn't make sense to me, but i got what i needed out of it

Do you use limited or full range?

[Deciazulado]

I calibrated my displays before the upgrade making the display make 16-> 0, and 235 be the reference white, so the memory for those inputs is still saved for that (what is now "Limited"). I will create a new permanent memory setting for Full (they'd then look equivalent) but haven't done it by the book yet, just a quick by eye one. For now I'm still mainly using the Limited as I carefully calibrated that, but afterwards I may go for the Full.

Having the Limited/Full option is good for displays that don't let you adjust/calibrate the full range on one of the settings (for example if your LCD can't reach it's maximum white with the 235 white in Limited, it robs you a little of your panels contrast, so in that case you should use Full if you need to maximize the panel's contrast), or to make your final image closer/more compatible with other sources you may have if you can't have separate settings for each video input. (Like if you have devices with IRE Set Up (black is 7.5 IRE or level 16), and calibrated black with those, and you have the PS3 on RGB, you might find Limited gives you blacks similar or equal to those; or if you have a computer 's RGB output and the PS3 RGB output hooked to the same display, then Full would make them equivalent, etc)

I don't see the limited/Full setting anywhere in the settings. am I blind? Where is it I am running v 1.9

[RichiPuppy]

I think its under display, by resolution settings.

[Deciazulado]

I'm not near my PS3 (I should buy a portable case for it ) but I think that's on the BD/DVD settings under the RGB settings

You can also access them with the green triangle and change them on the fly while watching the movie (under picture settings icon? I think)

Which display do you own? I have a WD-65732 and have been pretty vocal lately about RGB difference between 1080p and all other resolutions. If you calibrate to 1080p, everything else is too dark; if you calibrate to everything else, 1080p is washed out. Lately, I've been using RGB Full for 1080p and then manually toggling to RGB Limited for everything else, which is annoying to have to do.

Aren't all BD's encoded in Yc-b/c-r? Then the question becomes which one would give the most accurate image. When sending RGB, aren't you essentially letting the player do the video "decoding" whereas when you send it out as Ycc, you're letting the display combine the colors and essentially turn it into RGB video to display?

Am I understaning this correctly? Yc-b/c-r is to bitstreamed audio as RGB is to LPCM audio?

I'm an audio nut much more so than a video nut.

I was messing around, with RGB and Yc/Bc settings while watching Mission Impossible 3.

I dont see a difference between RGB limited and Y Pb/cb.

RGB full however, it is more bright, the dark tones are more dark, which makes it less detailed. I couldnt see Ving Rhames's face in one scene.
And on the beginning of the bridge scene, the color of the asfalt was too bright and because of it, there was less detail.

Couldnt see a difference between RGB limited and Y Pb/Cb. It looked the same to me.

Plus, Y Pb/Cb also has a Y Pb/Cb Pr/Cr superwhite option, which you can turn on and off. It is off by default, I also couldnt see a difference when I turned the option on.

Could someone explain what this 'superwhite' option is, please?

I ended up leaving the Y Pb/Cb Pr/Cr , RGB option at automatic. And Automaticly it chooses Y Pb/Cb Pr/Cr, with superwhite turned 'off'.

I have a 26", so that might be a reason that I couldnt see much difference between the options.

What you guys think is the best choice?

The only place I know of, where you can acces 'limited/full' setting when watching a BD movie, press traingle, on the menu there is a 'AV settings' button. There you get these options.

...you may have to adjust your TV settings (contrast,brightness,color,tint...etc) after turning RGB Full on.

[mainman]

I think I figured out what "Y Pb/Cb Pr/Cr superwhite" is.
This option makes X.V.color output possible, if it is encoded in the source. Is this correct?

Yeah, but I will leave it at automatic, so no need for me to adjust the tv settings. Planning on buying a new tv anyway.

[DrinkMore]

I am hoping some of you all can help me get unconfused here. There are some settings that I don't know what they do or the best setting for me. I am using my PS3 via HDMI to a Dell 2407WFP-HC LCD monitor. Its going PS3 HDMI to LCD DVI. Full 1080p.

I just want to know what these settings are suppose to do? Which ones are the best? For instance, setting the selection on the PS3 for RGB Full Range (HDMI) to Full - gives the colors on my monitor a little boost. I can see it, but what is it? Lol.

Also, on my monitor, there is a setting called Color Format PC - RGB or HD YPbPr (below). I set it to HD YPbPr and the screen turns into an oil slick. All the colors go wrong which I am sure is fine if adjusted. However, I have never messed with it. Is this a good setting? What am I missing here? Do I want this setting or do I want RGB?

Please help! Thanks.



PS3:

BD/DVD Settings-

BD/DVD Video Output Format (HDMI) - Automatic-RGB-Y Pb/Cb Pr/Cr
DVD Upscaler - Off-Double Scale-Normal-Full Screen
Cinema Conversion - Automatic-Video

Display Settins-

Cross Color Reduction Filter - On-Off
RGB Full Range (HDMI) - Limited-Full
Y Pb/Cb Pr/Cr Super-White (HDMI) - On-Off



Monitor:

Color Format PC - RGB or HD YPbPr

[Deciazulado]

I would asume that if your Dell is a computer monitor, it would expect computer levels (0-255) from a DVI RGB input. If that's the case with your monitor, then RGB in Full is the correct setting. (Limited sends black and white as video levels (16-235))

[Stormyhog]

Is it safe to have the setting at full for your tv and how do you know if it supports it? Any suggestions would be great.

[JAG1977]

If blacks look grey and washed out with limited, use full.

[tsb]

for movies you shouldn't use RGB according to sspears

[JAG1977]

So what should you use?

[T-Town Oil]

i would recommend a tv calibration before messing with that...
