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  • Outdated graphics driver – The graphics card is primarily responsible for how you see things on the screen.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.

  • 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.

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.

For regular flickering in the monitor, it’s usually faulty connections, corrupt or outdated drivers, or a broken display to blame.
