Ive only calibrated 1 Optoma. It accepted an HDR signal but converted it to SDR, with a gamma of 2.2 – 2.4 (I dont remember). It do nothing beyond rec 709.

if in HDR mode, consider rec 2020 for your color space. But with the PJs you have listed, do not look for anything accurate beyond 40-50% of rec 2020.

the 150 nits (is my example), is what you would be measuring, with lamp on high and iris open. This is the PJ running at 100% capacity.

Start with the contrast at the default position. (on the Sony 60 is a good start, but will be clipping abit). Then look for Gamma presets or other settings that will move the EOTF to be brighter or darker to match the Calman reference.
