Peak Nits of Display? #27

Closed pbiancardi closed 1 year ago

pbiancardi commented 1 year ago

Should I be entering the peak nits of my display (120) somewhere in the mpv.conf?

I do this for MadVR but not sure how to handle with HDR Toys?

Not the developer, but I believe you should add the following line to your config file: glsl-shader-opts-add=L_sdr=120

This is.

My opinion is to use the reference white instead of the peak white of display, that when you are watching a SDR content the white always be show as peak, but it's 100nit or 203nit in grading works. From more specific point, when you use OBS to capture HDR video from the SDR screen, the white is default to 203nit, if you set L_sdr as 100nit, they get overexposured.
