I’m not sure if you’re familiar with the old US TV series “Raymond”, but in the words of Frank “Holy Crap!” Your response is excellent! I thought someone might have had the same question about that Test Pattern, but you took the thought about 87 times farther than I was thinking. I hope Spears & Munsil (as well as other test disc people) take note about complete documentation. Thank you! Or σας ευχαριστώ.
The reason I asked this question is that I have been trying to diagnose some color problems with my Sony BDP-s390 player and a Panasonic 42PZ85 and Westinghouse VR-3730 HDTVs. I originally noticed poor chroma alignment with the YCC=4:2:2 color output to the Panasonic plasma TV. Basically, following S&M suggestions for performance evaluation I found that the RGB color output to my TVs improved chroma alignment and gave me the best Chroma Burst and Chroma Zone Plate Test Pattern results. I improved the picture quality of both TVs or so I thought.
While doing research for this problem I came across Chris’s (http://www.avsforum.com/avs-vb/showt...3#post22012693
) work on a problem with the Sony S390 RGB output exaggerating GREEN output and clipping my TVs. So, I needed to look for color clipping levels in YCC=4:2:2 and RGB outputs for my displays. The S&M clipping display indicated a problem but I could not interpret the results without knowing the levels in the squares being show.
BTW, I noticed in the Right square the outer to inner squares go from 239, 254,244,251,247,239. Is the 244 square correct? It starts decreasing then increases for the single square then decreases toward the center low of 239. The count order looks funny (not monotonic)?NOTE: This Chart was corrected by ConnecTEDDD in this thread below.
