Screenshot of HDR monitor: jxr to png

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello ZMaura, this has to do with the depth of the image, the more values the more depth in the image relative to the colors it will display.

I leave below a link that explains well the question of the bits in the image

Hello again, this is a good question but I don't think I know and I don't know if you'll find the answer, because this type of algorithm is proprietary and companies usually don't disclose that.

Companies like Adobe, Apple, DJI, Canon, Nikon etc. have their own algorithms to make the image .jpg, . Mpg etc formats are standart of the defined by the Independent JPEG Group, you can find on the internet the original code that was made in 1991 for free, however companies later developed their own algorithm and this becomes intellectual property of each of them.

Hello Georges,
Thank you for the link but this is not what I'm looking for.
My question is specific to the algorithm that Windows uses to tone-map the JPEG XR image to PNG image.
I suppose the JPEG XR is defined in a wide color gamut (eg BT2020) with a PQ transfer function while the PNG is the result of a conversion from PQ to gamma transfer function in a smaller color gamut (eg sRGB).

How this conversion is done by Windows ?

On your console display settings, is HDR enabled? Would you please share a screenshot with me of your display settings?

Also, may I know which monitor you are using?

Here's my CORRECT pic from xbox.com:

Rewards and Games match each other, but they're both a picture I've never used or taken before - my avatar has never looked like that.
