HDR – Perceptual Quantizer (PQ)
About PQ
Perceptual Quantizer (PQ) is an electro-optical transfer function (EOTF) that allows for the display of High Dynamic Range (HDR)
content with a luminance level of up to 10 000 cd/m² and can be used with the Rec. 2020 color space.
If your provided HDR content has been mastered with PQ (e.g. Dolby Vision or HDR10), you can adapt the luminance on screen to
adapt to the provided content.
For optimal display of HDR content, this is just one value that will in

uence the projected image. When enter-
ing the desired screen luminance, take into account the distance of the projector to the screen and the quality
of the screen used.
