Hi,
This might be a noob question, but I am calibrating my LG OLED EG9100 (its a 2nd gen FHD OLED) and I am having difficulties with the Dif EOTF graph.
First the setup and settings:
ColourSpace ZRO + TPGenerator 1.6 (YCbCr4:4:4) 8bit limited - Rec 709 (default which is gamma 2.4)
Expert1 Settings - Low (Limited) - 10% patches - Gamma 2.4 - All processing OFF
My Steps:
-. First I use the Brightness and Contrast patterns to set the correct brightness and contrast, so that total black is 16 and total white is 235.
-. Measure a complete IRE 21 steps gray 8bit. That gives me a RGB balance with a dE of around 4 and and Dif EOTF (and EOTF) that is not very straight.
-. The problem is that the whole RGB is way over the 0.0 line. Changing the brightness lower the whole RGB, but it also crush the blacks un the brightness pattern.
-. If I use a Rec 709 with a 2.2 gamma, and set 2.4 in the TV, then the whole RGB is below the 0.0 line (but even a little bit closer to the line).
Any suggestions?
Thanks in advance.
