Pattern Insertion to combat image retention contamination between patches

Open brunogm0 opened this issue 2 years ago • 2 comments

Since OLED and Plasma have a significant image retention, other calibration software offer this "refresh" insertion every few seconds. The refresh pattern is full field 25% gray. one also can optimize the pattern order to account for much significant hue or lightness retention.

Like after measuring cyan if there's no refresh and the next pattern is magenta, there is significant contamination.

Calman inserts 25% gray for 5 seconds the frequency of such varies by SDR (45s) or HDR (5s)

So it already supports it but only for a few outputs like resolve, Prisma... Then the issue really is supporting it in direct display, webhost, ...

Also webhost should configure the winsize instead of full only.
