Proper Method to Adjust Basic Color Setting?

What is the preferred method of adjusting the color setting of a LCD without advanced color management capabilities? My daughter's display has blue only mode as well as red only and green only modes. In using the AVSHD disk and the blue mode, the proper color setting was 51. In using a ColorMunki and the red pattern, this setting produced an oversaturated pattern. I needed to decrease the color setting down to 47 in order to minimize the red delta E. The other colors, however, were then quite a bit under saturated. I turned the color up 1 tick to 48 in order to better balance the errors, however, the other colors were still a fair amount more under saturated then red was oversaturated. I would appreciate some advice as far as how to better understand what is occurring and what I should be trying to accomplish. Thanks.

If using the RGB only filters, you can find the right color setting for each primary and then split the difference or set it by eye within the range you calculated. If using a meter, you want to minimize overall dE for all three primaries.

Thanks for that. I did find a Calman video on YouTube that shows setting color with a meter but it suggests only using the red pattern and minimizing the Delta E for that primary only. What you suggest makes sense.

Why do you suppose that there is so much difference in using the blue mode and AVSHD color pattern vs the meter method?

I personally set red to the correct luminance to minimize deltaL for red. On my set this also gets green exactly correct. Blue for some reason ends up much lower than green and red though. Getting red correct is important for accurate skin tones (assuming grayscale is already correct). Alternatively, you can minimize overall error like I mentioned earlier. Whichever color setting ends up looking subjectively better with reference material is the one you keep.

Greetings

When you do color with the blue method and then the red method ... figure you have a range to work with.

Put up an image of a person and then go back and forth between the two settings and figure which part of the range you want to keep the setting at. There is no perfect here.

What might be interesting is to see just how little it may visually make when you look at real images versus looking at the program layouts. Some enthusiasts make the mistake of assuming that what looks like huge changes on the computer are huge changes in real images ...
