Hi Nga Nguyen,
We understand you're experiencing an issue with screen brightness on your Surface Laptop 4, particularly where the display becomes excessively dim when set below 100%. This issue has been observed on devices using AMD graphics drivers and may be linked to recent updates.
Recommended Steps to Resolve the Issue
1. Rollback AMD Graphics Driver
· Open Device Manager.
· Expand Display adapters and right-click on your AMD graphics device.
· Select Properties > Driver > Roll Back Driver.
· Choose a version prior to Adrenalin 23.9.2, such as 23.7.1, which has shown stable brightness behavior.
2. Uninstall AMD Adrenalin Software
· Go to Settings > Apps > Installed Apps.
· Locate AMD Software: Adrenalin Edition and uninstall it.
· Restart your device to apply changes.
3. Disable Adaptive Brightness
· Navigate to Settings > System > Display > Brightness & color.
· Turn off Change brightness automatically when lighting changes.
· If available, disable Content Adaptive Brightness Control (CABC) in your UEFI firmware settings.
4. Use Microsoft Basic Display Adapter (Temporary Workaround)
· In Device Manager, update the display driver manually and choose Microsoft Basic Display Adapter.
Note: This may reduce graphics performance but restores basic brightness control.
