So any consensus on this subject here. I was curious about this. I only run one HDMI into my LG. I have done a pretty nice calibration now using my Sony Blu-Ray player and AVSHD. I was just wondering if I could just calibrate the display itself like this and get rather similar results. Would that be considered good or is this not something that theoretically works. From Killerbeenl's numbers above, it looks like the inner patterns match up pretty well.
