Surface Pro 9 Screen dimming and brightening semi randomly

Question

Hi

A somewhat happy owner of the new Surface Pro 9 but I've noticed that when on battery, my screen keeps dimming and then returning back to its original brightness.

The dimming will last a few seconds and it is somewhat random and not related to the ambient brightness. While in a word document, it will be fine and then when I stop typing, the screen will dim for a second and then go back to normal. Not always but I seem to be able to recreate the issue about 9 out of 10 times.

If I switch off adaptive brightness, I no longer have the problem but it seems odd that I would have this problem.

As anyone experienced the same or similar and is there a workaround other than switching off adaptive brightness (I use it with my other devices without any issues..)

many thanks

Hi caleeeb,

Thank you for reaching Microsoft Community. We're sorry for the inconvenience this has caused you.

Adaptive brightness control is a feature that helps your system in adjusting the screen brightness based on the content that's displayed on your screen. For example, if you’re watching a video that has a dark scene, followed by a brighter scene (for example, one that shows a bright sunny day), the brightness and contrast may change. This is normal. 

Content adaptive brightness control provides ideal brightness and contrast levels, while saving power and providing longer battery life at the same time.

If these brightness changes are distracting, or if you work in photo and video apps where color accuracy is important to you, you can turn this off any time. When you turn it off, it can result in shorter battery life. 

1. Select the Start button, then select Settings> System> Display.
2. In Display settings, select Brightness, and then for Change brightness based on content, select Off.
