Question

HDR not displaying

Trying to setup an HDR color space using Windows HDR and HDR display (as my only and primary monitor)
But ticking Display Color Management doesn't seem to do anything, even when working in a Rec2100 space.
Highlights never go over pure white, even though windows is capable of doing so.

Are you actually working in 32bpc? Is the correct monitor profile used for the preview?

Yes, I'm working in 32bpc,

and what do you mean by monitor profile? - I'm just in 2020PQ color space, and have my monitor set to the same. And windows HDR is active.
Nothing in After effects exceeds the 100nits white point, no matter how much I pump up the exposure, and the scopes clearly show details in the 400 - 1000 nits range. But monitor clips the whites.
In Premiere it *does* work, but not in AE.
Driver issue? CUDA / DirextX issue?

    We're you able to find a solution?

    I too am having trouble with my HDR content and exporting with after effects or media encoder

      You need to be much more specific and provide exact settings, screenshots, system info. From specific issues with hardware acceleration to simply missing a tick box somewhere this could be anything. That said, I have the feeling you may misunderstand HDR inside a color managed environment like AE vs. native Windows rendering and how it affects the displayed colors.

        As far as I can see I have all the hardware acceleration to CUDA, not software.
        The comp window just looks washed out like HDR looks on a non-HDR display.
        HDR is enabled in Windows, and Premiere *is* showing HDR in the main window.
