I found that if I turned on HDR function, the white picture (painted in windows painting tool)would not be output as (255, 255 255).

I wonder what is the conversion formula？

    Hello

    When High Dynamic Range (HDR) is enabled on a Windows 10 display, it allows for a wider range of colors and brightness levels, which can affect how colors are displayed. In an HDR environment, white may not be represented as the standard RGB value of (255, 255, 255) due to the expanded color gamut and dynamic range.

    The conversion formula for representing colors in HDR can be quite complex and may involve various factors, including the display's capabilities, the content's metadata, and the rendering pipeline. There isn't a single formula that universally applies to all HDR displays and content.

    If you have specific concerns about how white is represented when HDR is enabled on your display, you might want to explore the display settings or consult the display manufacturer's documentation for details on how HDR is handled on your particular monitor. Additionally, some applications and games may provide their own HDR settings that allow you to fine-tune how HDR content is displayed.
