you should not use hard clipping, instead, use roll-off. Also, note that setting a mastering display black level to above 0 will clip values below that point, which is why I wouldn’t recommend that either (besides, 0.1 cd/m2 for mastering display black level would be extremely high).
2018-09-01 at 13:54 #13398Hello , thanks for reply
I change the setting like attachment , it is batter but still looking darker they 3DLut off
Please give me advice
My monitor is Philips Momentum 328M6FJRMB (peek 425~450 , black 0.12)

The luminance is specified by the given target peak. That it’s brighter with the 3D LUT off doesn’t really matter, because the display without 3D LUT is very likely not accurate at all, so it is not a good point of reference (the original problem you had was also not luminance related, but black crush due to an unsuitable setting for mastering black level).
From the screenshot, I see you are using luminance preserving perceptual intent. Any specific reason for that?

No specific reason I was testing change this option will make any effect or not , So far it does not take effect

And I do try black output 100% still looking like over-saturated and darker
And I do try

2018-09-02 at 17:44 #13413Which is which in the screenshots? Is this a HDR display?
2018-09-02 at 18:01 #13418截圖中的哪個是哪個?這是HDR顯示器嗎?
Yes , It pass DisplayHDR 400
In last replay it is black output 100% and Absolute colorimetric with point scaling
And left is 3DLut off right is 3DLut on

2018-09-02 at 18:25 #13420Alright, in that case I don’t think 3D LUT settings are your problem, but that the display employs its own (undefeatable?) tone mapping, and you tried to profile it through said tonemapping. This is fraught with problems, because the display tone mapping may mess up the display response and the profiler will not be able to make sense of it. Ideally, you want to profile the display without any tone mapping or “dynamic” display processing. If you cannot disable the display tonemapping, you have two options:
- (Recommended) profile the display in non HDR (“SDR”) mode.
– or –
- Enable white level drift compensation on the “Display & instrument” tab in DisplayCAL and set patch sequence on the “Profiling” tab to “Maximize lightness difference” and profile the display’s HDR mode.

Hello, Thanks for reply
I try HDR to SDR it work great , But when I try to use the other options it will make 3DLut look like this

I think it is because DisplayCAL only support SDR contents?
Or do I do something wrong and make it only do SDR??
