hi Amir…it depends on what the source is…..as of right now….
pretty much all 4K is at rec 709 with Gamma of 2.4 (BT1886).
HDR does not exist in 1080p, only in UHD. HDR specifies a larger gamut than 709 but it is not yet standardized.
Thank you Gregg.
For 4K and 2K calibration with Rec.709 do we have to change the software settings?How software detect we are calibrating a HD or 4K projector?my mean is the test patterns that use for measuring are the same while working with any dispaly resolutions?
