I am not exactly sure as why one would do this even though I tried it and it looks great.
Anyways, I have both a PS3 and an XBOX360 running into a receiver and out the same HDMI cable to the TV.
So when I set it to "nonstandard", the picture got noticeably lighter (grayish blacks) as it did on the PS3 before I changed it to full RGB.
I am guessing that now I will need to do the same for the 360.
However, the only equivalent was the "Reference Levels" area where you have something like Standard,Intermediate, And Expanded I think.
Is this the same as "Full RGB" or is this the same as "Deep Color Output" on the PS3? (And now I am not sure what to put this on, on the PS3)
When I put the 360 on Intermediate or Expanded it seems to restore the color/black level but then I do not know what is what because of no explanation.
This all throws me off because I could swear that the Spears and Munsil guys said on their thread to put the PS3 on "limited."
Thanks to whoever knows.
Let me try to explain what those settings are.
"Limited" and "standard" means that the digital signal uses the range 16-235 for each of the RGB values. This means that each of the three primary colors (RGB) only has 220 shades (235-16+1). If you multiply all combinations of RGB shades, you get a little bit over 10million possible colors. 220^3 = 10648000 colors to be exact.
"Full" and "non-standard" means that the digital signal uses the range 0-255 for each of the RGB values. This means each of the RGB colors can have 256 shades. Which means you get over 16million possible color combinations. 256^3 = 16777216 to be exact.
So what does this really mean? It means that when set to "Full" or "Non-standard" mode, your display has the potential to display more colors, which can equate to smoother gradients. However, just because you set it to "full" doesn't mean it'll be better. In fact, it could be worse. The reason is that almost all production video contents are encoded using the "limited" range. By setting your PS3 and TV to the "Full" range, your signal range will be different than the original video source. This can cause even worse gradiation (banding) due to rounding errors when you remap 16-235 to 0-255. So when would you want to use "Full", you might ask? You'll want to use it for computer graphics that's not pre-recorded. This means a computer or gaming output. However, there are a lot of caveats. Many HDMI connection from PCs will default to the limited range by default. XBOX360 for example is "limited" by default and setting to "full" will result in internal remapping which can cause banding. I'm not sure what exactly PS3 does.
My recommendation is unless you know exactly what your device is outputting and you know exactly how the source material is encoded, it's better to stick to "Limited/Standard". In the case of your PS3, if you use it to watch videos most of the time, keep it in "Limited/Standard" as well.
Personally, the only time I use Full/non-Standard is when I use my TV with my PC. I ensure that my video card is outputting 0-255 and set my Panasonic to "non-Standard". In this mode, desktop graphics such as pictures will get the entire 16million colors, but my videos will still have banding.
So really, if you're using your TV to watch production videos, DON'T
I hope this helps.
