Why does the Xiaomi 15T Pro screen brightness vary when playing HDR videos?

Thank you for your support of Xiaomi. HDR videos feature a wide range of brightness and contrast, enabling more realistic and immersive visual effects.
To reproduce these effects accurately, the Xiaomi 15T Pro automatically adjusts screen brightness during playback. As a result, some scenes appear temporarily brighter or darker depending on content, contrast, and ambient lighting. This behavior is normal for HDR playback and does not affect the overall viewing experience or image quality.
The perceived brightness also varies with ambient light and adaptive brightness settings. These adjustments help HDR videos display highlights and shadows accurately, as intended by the creators.
For a more refined screen brightness, please adjust the following settings:
  1. When watching HDR videos, pull down the status bar.
  2. Manually adjust the screen brightness to achieve a more comfortable viewing experience.
These steps help maintain consistent visual performance, improve color accuracy, and provide a comfortable viewing experience.
