Well, using some stuff Ive kept around on my DVR (red skin tones, red blacks, greenish blacks), I still had a slight issue with my last calibration above, plus I think 95 contrast was a bad move. FYI, I have THX Cinema calibrated on this display by a pro, so I can use it as reference flipping back and forth, granted some of these issues in Custom/ISF Ive run in to are blatent to the eye. The reason I am trying ISF modes is because while THX CInema looks good, it is a tad dim for me.
So, I punted, and tried a different approach today. I threw in Spears and Munsil 2nd gen, and used it for the calibration. Up until now I had stayed away from the equal energy patterns but I figured what the hell at this point. I also went back to Normal Color Temp, Ive not been successful at all with Warm 2.
The equal energy grayscale patterns are quite nice and offered results that were quite consistent. One wild thing was that with the 2.4 gamma setting, you got a 2.4 gamma result almost the entire way across. 10% was low, as Ive always seen and need adjustment, but it was about the only point I had to adjust to get it flat. So that is a BIG shift from the other pattern discs using 10% and 6.5% windows. I was really surprised that 70-90 did not have some sort of drop, because the patterns have a lot of white on the screen when they are up, but I wont even pretend to act like I understand how they work. Zoyd could better do that.
The only drawback is their gamut patterns offer 25-100% amplitude, but all are 100% saturation. So instead of calibrating to 75% amp/75% sat, I had to do 75% Amp/100% saturation. Finally, I noticed the grayscale results when doing 2pt were not what Id seen with other discs, so I cant explain that either.
After finishing I threw in DVE and used some of the demo material, fleshtones look good. I fired up the DVR and looked at Game Of Thrones, Longmire (bad red issue in fleshtones) and watched some Fifth Element and Dark Shadows on the premium channels. I cant find anything to complain about right now, I mean it looks good on everything Ive had a problem with the last 2 weeks in my experimentation. Once again, having THX Cinema calibrated by a smarter person than me with a better meter helps to for comparison
. Finally, what I find with the equal energy grayscale patterns is that 100% maxed out at 34.5fL, regardless of whether I used 85 Contrast or 95. Sometimes as you got over 85 it would drop, very odd... I always set brightness with Spears, so that was no different.
