6.8.5 Displaying HDR content
–
Perceptual Quantizer (PQ)
About PQ
Perceptual Quantizer (PQ) is a non
–
linear 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.
How to properly display HDR content?
If your provided HDR content has been mastered with PQ (e.g. HDR10 and Dolby Vision), a few changes can
be made in order to project the intended mastering on screen. These changes are necessary because HDR
content has been mastered specifically for HDR capable displays that are watched in living rooms. These
conditions are different from a non-HDR projector and darker cinema-like environments.
The projected HDR content depends on the following factors:
•
Mastering luminance
: This is content-specific and cannot be changed.
•
Screen luminance
: Every projection screen has a specific luminance (measured in nits or foot-lambert).
Entering this luminance in the projector will adapt the content towards the intended HDR result.
•
HDR Boost
: A variable
“
booster
”
that may amplify or downplay the HDR output.
How to set the PQ?
1.
In the main menu, select
Image
/ Advanced settings / HDR
The HDR menu is displayed.
2.
Select the desired Unit (nits or foot-lambert).
3.
Enter the Screen luminance (either in nits or foot-lambert).
4.
Alter the HDR boost if necessary. You can modify this value to somewhere between 0.8 and 1.2.
