hdr displays the perceptual quantizer pq published by smpte as smpte st 2084 1 is a transfer function that allows for hdr display by replacing the gamma curve used in sdr 2 3 4 5 it is capable of representing luminance level up to 10000 cd m 2 nits and down to 0 0001 nits 2 it has been developed by dolby 6 and standardized in 2014 by smpte 1 and also in 2016 by itu in rec 2100 7 8 itu specifies the use of pq or hlg as transfer functions for hdr tv 7 pq is the basis of hdr video formats such as dolby vision 2 9 hdr10 10 and hdr10 11 and is also used for hdr still picture formats 12 13 pq is not backward compatible with the bt 1886 eotf i e the gamma curve of sdr while hlg is compatible pq is a non linear transfer function based on the human visual perception of banding and is able to produce no visible banding in 12 bits 14 a power function used as eotfs in standard dynamic range applications extended to 10000 cd m 2 would have required 15 bits 14 technical details edit
