I was asked by a friend how my calibrations went - done just last Saturday by Rayjr. Here was my answer: (BTW, Ray was meticulous, both explained carefully and showed key points to understand, documented the before and after charts for me, and noted key settings - as we found there was no saving after my neighborhood had a power outage in the middle of things!)
It went VERY well. I had to wait for Sunday's Tru Blood, that is where my most focused attention has been and it is a great source. The panels were good before, but now they and the show, almost follows Ansel Adams 9 (?) steps of white to black...with a lot of red. And definitely I see a difference.
Blacks are blacker. Before the blue was 20% overdriven, Red 12% underdriven so whites are whiter - even as the lumen level came down a bit. When it gets a white signal, no matter the white, it is not skewed anymore. No soft pinks, or cool blues. Noticeably whites stay neutral white.
The before and after charts were quite a sight to see, given there is really not a lot of adjustments (and those were subtly tweaked).
Each of R G B Low (about 30% brightness), R B G high (about 60% brightness) sets the gray level.
Contrast and Brightness for black and white level.
Color, and finally gamma - which is like an accelation of brightness.
(did I miss something?)
But the combos of all that make quite a difference.
And there was the turning off of most all other auto-filters, NRs etc.
Then....Rayjr set a Pure mode, Movie mode and standard mode. Pure being correct, and each of the others slightly tweaked brighter. But in my tests, I'm already calibrated to pure. And predominantly stay there - it is just SO perfect. Though I have to say with Beowulf, the gold dragon lit up beautifully with the brighter modes.
This all after I used my calibration disc. It only gets you white level, black level and color level. You need a spectrometer or similar and that feeds a laptop which drives a signal generator. All calibrated, to get the colors in line.
He also pointed out the color tint to the gray scale before adjustment and lack of it after. Once pointed out, it's distinct.
Less obvious, but noticeable is the utter detail that was being masked. Native film grain, facial complexsion, textures all are better - as is of course, color. I didn't think I would notice so much...and the more I watched the more I realized how much better it was.
So all in all, I would definitely say that calibration is of high value, and that Rayjr did an excellent job. As with the above, I have been suggesting him and calibration to all my plasma oriented friends (the LCD group don't seem to notice very much at all!).
