I preformed my best/dark room calibration using Cinema mode as a starting point. I was able to copy Cinema over to User 1 and rename it Night. Brilliant Color is off by default in Cinema mode and I left it off for my calibration.
Sharpness was defaulted to 8, I left it at 8. Pixel Enhancer 4K was set to 0. I found I could push it to 5 before seeing any objectionable artifacts when viewing 1080p content. There are 2 more enhancements called DCTI & DLTI, both are off by default and I kept them off. I kept Noise Reduction to 0.
Most of the time contrast set at its middle, default position is as high as you want to go, pushing the light output just before clipping. In Cinema mode I was able to push it 3 clicks to 53 eking out a few more lumens before clipping and leaving just a pinch of headroom.
Cinema out of the box performed decently but it did show 4 - 6 DeltaE between 10 – 100 IRE. Remember we want to be below 3 and I always strive to hit 1 or less if the projector is capable. The average color temp was 6850K range, a bit cooler than our target of 6500K (D65). After calibration, I was very pleased to hit 1 or less DeltaE across the entire grayscale (10 – 100 IRE)
I usually target a 2.4 (BT.1886) gamma for my best/dark calibration but found that the projector is really tuned to a 2.2 curve. When I tried to do a 2.4 I had issues with lower color saturation points (20, 40, 60, 80) being over saturated. Switching to a 2.2 gamma brought those mid-level measurements closer to their (REC.709) targets. After calibration I got an average 2.19 gamma.
Overall there were no real surprises with my best/dark room calibration. All of the controls work as there supposed to and yielded exceptional results with pleasing, natural colors and skin tones.
