Problems with grayscale LG B6 OLED after 3D LUT

[Anonymous]

21p doesnt work on any oled

grayscale turns into a rainbow if you adjust 21p settings.

only use 2p

use gamma 2.2 on the tv

its better to have more details near black so the 3d lut can reduce them  than the opposite.

still i wouldnt do 3d lut on these oleds

picutre gets worse

the only safe setting to change is the 2p settings

I try it with Calman and hromapure. Only with Calman I got an acceptable result. (3d Lut and Calman RGB)

I found a solution. Calibrate the tv in 2 points (30/100) 100% lets close to DeltaE 0. The 30% adjusts only to close DeltaE 2 (as maximum). Then, with Calman RGB (workflow advance) create a Matrix profile with 14 calibration points  (DeltaE avg 0.5) and 21p icc profile. Look great. Then, if you want you can adjust the values of the CMS. I look great, without black crush.

I will create a 3d lut for Madvr and be able to capture images.

Do that

Check grayscale ramp after the 3d lut 😀

Also changing cms only reduce bits.

Change to much and colorshades will look like 256 color mode from windows 3.1 in the early 90s
