I know that the color spaces are different for each standard (SD = 601, HS = 709) and the correct one I should be using for HD material and displays, but how do you interpret the pattern with your eyeballs? I'm assuming it is just a quick visual check.
More specifically, if I have a Blu-ray player and HD TV what should I be looking for? What is right? What is wrong? How do you know? In particular if you use the Belle Nuit HD Test Chart Pattern at http://www.belle-nuit.com/testchart.html
How do you use it? Then if you have a DVD (SD) and upscale to HD are the observations the same?
You need a blue filter that goes with the disk or a blue only mode within the TV. There are blue and white bars and blue and magenta I think.. the AVS disk has them labeled with the words Color and Tint.
When the pattern is up and flashing (avs flashes to make it easier to see) and you look at it through the proper color blue filter, the ides is that the white and blue will be the same color. What you are trying to do is match the luminance of blue with that of white by moving the color control.
Then look at the tint bars and use the tint control to make them the same.
If the set has a blue only mode, or blue filter mode in the menu, or it is a crt and you can turn off the red and green guns, you do not need the plastic filters. You put up the pattern, turn on the internal blue only and look at the pattern with out the aid of a hand held filter. Make you adjustments and you are done.
The thing about this in the digital world using HDMI, those controls should not even be there! They are there to keep joe consumer happy. A programmer had to wire the code to alter the values. I have a DLP projector from 2005, no color or tint for HDMI, those were analog controls. You would be better off just leaving them at the factory default assuming there is a centered default.
Don't get to hung up on color and tint, brightness, contrast, backlight, aspect ration (pixel mapping 1:1) and shaprness are more important to worry about.
I say this because like you, I had the same question not that long ago and have been asking these very same questions of every expert I have encountered..
Hum.. after rereading your post I think you may be asking about picking color space not setting color?
If you are talking about 4:4:2, 4:4:4: RGB etc.. I am at a loss as well at this time.. I ordered the SM bench mark disk and here is a web page that talks about the patterns.http://www.spearsandmunsil.com/artic...olorspace.html
