When I play an HDR video source in HDR mode on my HUAWEI laptop, the video is overexposed

Problem

When an HDR video source is played in HDR mode, the video is overexposed.

Cause

On a built-in HDR display (such as a laptop that supports HDR), both the brightness settings and the HDR/SDR brightness balance settings will affect the display of HDR content.

Brightness settings: When viewing HDR content in bright environments, you may need to increase the screen brightness in order to clearly view the displayed content. However, the darker the pixels are, the brighter the display is, so this reduces both the effective dynamic range and the overall contrast of the HDR content in an app. To improve the HDR content display, it is recommended that you view the HDR content in a dark environment and lower the screen brightness. When the screen brightness is set at an extremely low level, the overall contrast between the brightest and darkest content features increases. However, the darker parts of the content will be less detailed. For example, when watching a film, the features of a dimly lit room at night will be less detailed. HDR/SDR brightness balance settings:

It is recommended that you use the default HDR/SDR brightness balance setting, or a setting with a difference of only one level. These settings are suitable in almost all cases. To increase the overall contrast between the brightest and darkest content, increase the HDR/SDR brightness balance settings. Please note that this will reduce how detailed the darkest parts of the content appear, just as with the example of a dimly lit room at night.

Solution

1. Currently, this issue occurs only when HDR mode is used and a specific type of HDR video is played. The issue is caused by the overlapping of HDR functions and HDR videos, and does not indicate a screen or hardware issue.
2. To solve this issue, adjust the HDR/SDR brightness balance settings or disable HDR in the system settings.
   1. Adjusting HDR/SDR brightness balance settings:

      Connect the device to a power adapter, open the Start menu, go to Settings > System > Display > Use HDR, swipe up on the screen, and adjust HDR content brightness to a proper position, as shown in the following figure.

      

   2. Disabling HDR in the system settings

      Connect the device to a power adapter, open the Start menu, go to Settings > System > Display , and toggle off Use HDR to disable HDR mode.
