My plasma has a bit of black crush.I have box set to ycc444.Will using rgb on the box and setting tv to black level dark be better for this issue?

I've read a few times ycc is better and more colors, but cuts off blacks.A poster on pne8000 thread said rgb is best for that tv.

None of what you claim to have read is accurate.

You are still posting non-calibration posts in the calibration forum, don't do that. The question you are asking is not about calibraton, it is about color science.

The only way to tell if RGB or YCbCr is better is to look at both using a high quality source like Blu-ray. Most of the time there is no difference. Sometimes YCbCr looks better. Sometimes RGB looks better, but those happen only about 5% of the time. I have never seen a Samsung TV where RGB looks better than YCbCr -- that doesn't mean it's not possible, only that I have never seen one. All the Samsung TVs I have looked at reproduce RGB and YCbCr the same -- there is no difference.

RGB and YCbCr 4:4:4 contain EXACTLY the same information.

RGB can have digital levels of 0-255 which is usually found on computers. Or it can have digital levels 16-235 which is what consumer video sources use.

YCbCr should ALWAYS have digital levels 16-235 because it is the primary consumer video data format. 16 is black. There is no cutting off of anything. Black is digital level 16. Period.

In RGB, black could be 0 or it could be 16, it depends on how the video is formatted.

Using the wrong digital levels setting will look pretty bad.

Thanks for the help..By the way I got my set looking about as good as I can get it.I look at it and often impressed and I payed $700 plus the box and think people probably payed several thousand years ago and there tv was not as good as this one.If this tv did not have the aggressive abl I bet they would of sold it for 10 thousand some years ago.

Samsung terminology is confusing:

Input YCbCr > HDMI BL defaults to grayed out Normal which is 16-235
Input RGB > you get a choice of Normal or Low. LOW is 16-235. Normal is PC level.
