I’m not using any LUT. Anything outside of movies work fine. Games, desktop, YouTube etc.If you've calibrated your tube for inky blacks, I'm assuming you're using a LUT adjustment to compensate for the crushing associated with using a low G2. If so, make sure "disable gpu gamma ramps" is unchecked in madvr. And you definitely want 0-255 not 16-255.
I’ll try the disable gou gamma ramps.
0-255 seems to be advised against from what I’ve read. Blacks are crushed when I’m in 0-255.
