HDMI ycbr444 vs RGB

[VegitoBond]

should i use ycbr444 or RGB for my hdmi output?

[Sauron]

ycbr should be a bit better

So what about this then

 

 

I do not recommend ycbcr444 for traditional displays, as it oversatures reds and magentas. And also adds a slight blur, as its a compressed signal format, unlike RGB which is uncompressed.

 

I`m using full RGB and it looks great.

Now that I have you thoroughly confused, let's get back to the issue at hand. ALL video stored on modern discs, be it DVD or Blu-ray, are stored as YCbCr with a range of 16-235. But, the content is mastered such that 0-255 is present in the tape domain (the SDI stream - D5 archive tape, etc.) It is then captured into a computer and then the computer will decide what to do with it - preferably retaining the extended info (all data from 0-255). This entire range is then compressed into the 16-235 range accepted by DVDs, Blu-ray Discs, etc. When you play that back on a system set to 16-235, you get all the information as it was intended with no gaps. If you mismatch and play back with RGB (0-255) settings, you'll clip off the black and white levels and black will look "dark gray". Additionally, you won't be able to view the Blacker-than-Black images found on most video test discs. Let's look at this pictorially to get a better understanding of how this works:

 

At least for watching movies we are supposed to use YCbCr to see them in the way the authors wanted.

RGB and YCbCr aren't the same thing in the sense that you can say one will always be better for everything. For most things you will want to select full range RGB, there is very little/no visual benefit between using full RGB v YCbCr, the contrast ratio & luminance will remain the same along with the gamma. 

If you look at a side by side comparison of colour accuracy between the two there will be slight changes in delta E, but YCbCr isn't colour spacing, it's just a different representation of colours, and there are no visually significant changes between the two. 

 

In general for most use, you want to use full RGB. For blue ray content and stuff similar to it you want to use YCbCr. Converting RGB to YCbCr isn't always optimal and can make for a slightly worse experience.

 

But in general just make sure you aren't using limited RGB and you should be fine.

too bad Nvidia 3d settings doesn't allow ycbcr 4.4.4  full  like the RGB one.  You can force ycbcr 4.4.4 (0-256) a.k.a full by enabling digital vibrancy but then it reverts back to 16-235 as soon as it detects a change in resolution.   Why does nvidia continue to refuse to give us the option like they did for RGB one.   I love the way games look when ycbcr 4.4.4 is enabled, but it's too much of a hassle to continually having to enable digital vibrancy to force 0-256.  I wish there was a tweak to keep it locked.

Q: Since video games use the Full RGB palette, shouldn’t I use Full RGB when playing video games ?

A: Yes. Most video games are designed using the Full RGB spectrum since they are designed on computers which use that.
