My purpose is to create a 3D LUT for madVR so I can get the best picture quality with my system (PC to Samsung Q70 TV) when watching movies.
As we all know that most LCD TVs don’t have very high contrast, and if Gamma is not properly calibrated, some dark details will be lost. So I have this question, to save as much dark details as possible, what will be the best settings when creating 3D LUT for madVR?
On TV: should Gamma be set to BT.1886 or 2.2?
On DisplayCAL: should Gamma be set to BT.1886 or 2.2 (relative 100%) or 2.4 (relative 100%)? My understanding is that “relative 100%” helps saving dark details. Please correct me if I’m wrong.
My TV has enough luminance output, 250 cd/m2 under 709 and 450 cd/m2 under HDR.
Many thanks to your input!
