I'm sorry for my English.

I'm using version 6.3.4.1696,and I have a problem with getting the correct LUT. Peak Luma/Peak Chroma/Fit Chroma switch does not work. In any position I get LUT with Peak Luma only. But I need Peak Chroma. In the previous versions everything worked well.

Everything is working correctly for me.
What does the 'profile' look like.
Forward it to me at my usual e-mail address.

Cheers,

Thanks for the reply. Profile posted.

Have checked the profile.
It looks like the data in the profile has the peak Luma and Peak Chroma almost identical when a LUT is generated.
The small potential difference is not being seen as the profile is not a Full 17^3 profile, but a Hybrid with a small cube size.
The variability of the display means the profile cube is not large enough to correctly map the display.
You need to run a 17^3 profile, not a hybrid with a small cube, for that display - although the result from a Peak Luma and Peak/Fit Chroma will be very similar.

Hope this helps

Steve

Understood. Thank you.
