Why does my screen brightness keep changing in Windows 11?

Many users are facing this constant problem with the brightness of their screens. They say the screen’s brightness keeps changing even after upgrading their system to Windows 11, the latest possible version. The potential causes for this issue on any Windows system are listed below:

Outdated graphics driver – The graphics card is primarily responsible for how you see things on the screen. The better the graphics card specifications, the better will be the appearance. So if the graphics driver is not updated, it might cause such problems. Adaptive brightness enabled – There is a feature called Adaptive brightness in the Windows system, which lets the screen brightness change according to the surrounding lights. Auto-dimming feature – When the system is in battery saver mode, it changes the brightness to dull to save power consumption if this feature is enabled. Screen resolution – If the screen resolution is not set to the recommended value, it might create issues like those discussed in this article above. Damaged screen – This type of issue happens when the screen or monitor gets damaged internally or externally.

This article guides you with the best and quick seven ways to fix the screen’s brightness issue mentioned above.

How do I stop my monitor from auto-adjusting brightness?

Before applying any advanced steps:

You can try connecting your monitor to another Windows system to see if it works. If the monitor shows the same problem after connecting to another device, this means the monitor is damaged. You may have to repair it or replace it with the new one.

1. Change brightness settings

2. Disable the Adaptive brightness settings from Control Panel

3. Update the graphics driver

If manual updates didn’t work, you could use a specialized tool to scan, find and update outdated drivers automatically, safely, and fast.

4. Turn off the auto-dimming feature while in battery saver mode

5. Run the Power Troubleshooter

6. Change the screen resolution settings

Why does my LCD screen become dim or sometimes flicker or brighten intermittently?

If the screen’s brightness changes randomly, it could be due to variations in the amount of light around the device. The sensors in the display adjust the brightness according to these changes. In case the display brightens intermittently, the sensors are likely broken. Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions. For regular flickering in the monitor, it’s usually faulty connections, corrupt or outdated drivers, or a broken display to blame.
