The graph says this:Ok, so the higher those color bars, the worse the picture accuracy? But I have seen reviews that say X monitor has good picture, that seem to have color bars higher then those that it says didn't have such good quality picture. And I can't make much sense of what the graph is suppose to say? Where do I want those two or 3 lines? What do those numbers in the lower left hand corner mean?
The number on the left is the delta value. Delta is a difference between two factors; here it’s the difference between the measured colour on the panel and the actual colour that is our target.
# A delta value lower that 2 results in a visible deviation from the actual colour.
# A delta value over 4 or 5 results in wrong colours.
# A delta value between 1 and 2 results in precise but not perfect colours.
# A delta value lower than one results in almost perfect colours. The target is 0.
# Everything between 0 and 1 is barely visible to the human eye.
