Dear kuunaama,

Thank you for reaching out with your question regarding the Windows HDR Calibration tool. I’m happy to clarify the details for you.

The HDR Calibration tool in Windows 11 helps you fine-tune the brightness levels of your display for an optimal HDR experience. Here's a breakdown of the values you mentioned:

Minimum Luminance (Slider from darker to brighter, 0~1): This slider controls the black level or the minimum brightness that your display will show when using HDR content. The value 0 represents the darkest possible luminance, while 1 represents the brightest possible luminance within this range. These values are not measured in nits but rather on a scale from 0 to 1, where 0 corresponds to the absolute minimum and 1 corresponds to the maximum brightness defined for this setting.
Maximum Luminance (Slider from darker to brighter, 200~2000 nits): This slider adjusts the peak brightness your display can achieve when displaying HDR content. The values are represented in nits, and the slider typically ranges from 200 nits (for more budget-friendly displays) to 2000 nits (for high-end HDR-capable monitors). The value you set here should match or be close to the peak brightness specification of your monitor to achieve accurate HDR rendering. If you’re unsure of your monitor’s peak brightness, you can check the product specifications or run a quick online search for your model.

Key Points:

Minimum Luminance (0~1) is a relative scale, not in nits.
Maximum Luminance (200~2000 nits) refers to the peak brightness in nits.

By adjusting these sliders, you're helping your system understand the range of brightness your display is capable of, enabling Windows to provide the best possible HDR experience.
