I'm not sure if you can get 10% below 3 but it really doesn't matter since it's so dark. You can get it within range with the 10pt controls and fix the gamma as well. Again a pain in the ass to do but worth it since the low end gamma is so bad with local dimming on.
So when I was tweaking the numbers, I messed it up too bad and decided to start from scratch. But I'm having trouble getting it close to as good as it was before. I took pictures of the numbers before fiddling, but I'm curious - what is the best practice, to calibrate up from 0-100 or down 100-0? I've read to do the latter, and I think was somewhat successful with it in the past, but I've also found, with this set, that whatever you do, the controls directly before the %-output you're attempting to calibrate also affect white balance at that level. (In other words, the controls at 90% will affect 100%. But 100% will also!) In general I've been trying to strike an OK balance between white balance at the highest and lowest ends of grayscale using RGB Gain/Offset first, using the Pre-Calibration Grayscale Level chart as a guide, and then fiddle with the 11-pt WB scale from top to bottom. But I can't quite get it right this time with the relative ease I did last. (This is with FALD on, no more clipping whites, light output of 120-125cd/m^2 @100%
white.) I want to avoid driving myself crazy this tine, and though I still have the local-dimming numbers (took pictures) to fall back in, I'm not sure that try to tweak those to work with FALD and proper contrast again is the way to go, given how much dE got screwed up when I tried to last time (also went from top to bottom on that sweep). So if you have any more advice on this, I'll gladly take it. Thanks again!
P.S. I realize this would have been more proper as a PM, but I don't think you have those turned on? Or else I just don't see the damn link, heh
