I had some time today, and checked the calibrations on my tv's. When I was done I tried using different sources from my Panasonic Blu-ray (BD655) using the AVC709 disk, and from my laptop using the HCFR patterns, and CalMan Pattern Generator. This was done one after the other, all on the same HDMI input on my plasma set. No changes were made to the set. The video output from the laptop was set to factory defaults before I began.
Comparing the data, I see some differences in the data, mostly in the gamma levels, the color luminance, and the total light output. RGB seems to be very close one to the next.
Double checking to be sure all software setting were the same, I still see differences in the data from the different sources. To verify what I am seeing, I repeated the readings on another set, an LCD.
Which source do I trust as the correct one, and most accurate? If all the sources should be the same, what have I missed configuring them?
