8. Reset Display Settings
Never fail to keep a close eye on the wrongly-configured or conflicting display settings as they can cause screen dimming issues. These settings might be accidentally changed by applications, users, or system updates. When these settings are misconfigured, the display may not respond to brightness adjustments properly, resulting in unwanted dimming.
Resetting the display settings to their default values ensures that the system functions as intended, with the correct resolution and refresh rate. This action restores optimal visual performance and helps prevent any errors that could lead to dimming or other display issues.
- Open Settings and go to System > Display.
- Under Display resolution, choose the recommended resolution.
- Scroll down to Advanced display and click Display adapter properties.
- Click Color Management and reset the settings to default.

9. Check for Windows Updates
Are you up against the outdated version of Windows on your PC? If you are not sure, be sure to check for the latest updates via the Settings app > Windows Update. If the latest Windows 11 update is readily available for your device, go ahead to download and install it without fail.

10. Check for Overheating Issues
Be warned that overheating can cause your system to throttle performance to prevent damage, which can include dimming the display. This is a built-in safety feature that automatically reduces power usage when the system detects high temperatures.
If your laptop or PC is overheating, it can trigger the dimming of the display to reduce strain on the components. Ensuring proper ventilation, using a cooling pad (for laptops), or cleaning the internal fans and vents can help prevent overheating, allowing the system to maintain normal brightness levels without thermal-induced dimming.
- Ensure your computer is in a well-ventilated area.
- Clean out the fans and vents to remove dust.
- Consider using a cooling pad (for laptops) or an additional fan for desktops.
11. Adjust the Display Brightness in BIOS
On certain systems, BIOS settings can influence hardware performance, including display brightness. Sometimes, BIOS settings related to brightness or power management may override Windows settings, causing the screen to appear dim or bright unexpectedly.
Adjusting the display settings directly in BIOS allows you to reset or fine-tune the brightness settings for better consistency. This is particularly helpful if the issue persists even after adjusting software settings in Windows, as BIOS changes can address more fundamental display configuration issues at the hardware level.
- Restart your computer and press the key (usually F2, Del, or Esc) to enter BIOS.
- Look for settings related to Display or Brightness.
- Adjust brightness settings and save changes before exiting.
12. Update Graphics Drivers

Should the screen dimming issue continue to haunt your PC, why not go a little further and reinstall the graphics drivers? Well, for times when you are dealing with corrupted drivers that don’t seem to mend their ways even after an update, fresh installation becomes the way to go.
On your PC, fire up the Device Manager and expand the Display Adapters section > Right-click on the graphics card > Uninstall device > restart your device so that Windows will be able to install the latest drivers automatically.

14. Check for External Monitor Issues
If you’re using an external monitor, the screen dimming may not be related to your computer settings but rather to the monitor itself. Monitors sometimes have their own power-saving features, like automatic dimming based on input signal or ambient light, which could be causing the issue. Additionally, faulty cables, connection issues, or hardware malfunctions can result in dimmed screens.
Checking for secure cable connections, ensuring the monitor’s brightness settings are configured correctly, and testing with another cable or device can help identify whether the issue lies with the monitor rather than your computer.
- Ensure that the monitor is properly connected to your PC.
- Check the monitor’s Brightness settings from its on-screen display menu.
- Use a different cable or port if necessary.
15. Check Battery Health (Laptop Users)
If you’re using a laptop, battery health can significantly impact the performance of your display. As the battery deteriorates over time, the system may automatically adjust brightness to save power, leading to dimming or other display issues.
Checking the battery health in Windows 11 allows you to assess whether the battery’s capacity has diminished to the point where it impacts system performance. If the battery health is poor, it may be necessary to replace the battery to restore full brightness control and prevent unexpected dimming due to power-saving measures.
- Open Command Prompt as Administrator.
- Type powercfg /batteryreport and press Enter.
- Locate the battery report in the file path shown in the prompt.
- Review the battery health and replace it if needed.
16. Test in Safe Mode
Now is the right time to trigger Safe Mode to determine whether or not the screen dimming issues are related to third-party software or background processes. With the ability to load only the necessary system drivers/services and disable the redundant third-party applications that could potentially interfere with your display settings, this mode makes it easy to spot the culprits.
- To begin with, restart your PC and press Shift + Restart.
- Dive into Troubleshoot > Advanced options > Startup Settings.
- Select Enable Safe Mode.
- Check if the screen dimming issue persists in Safe Mode.
If the screen operates normally in Safe Mode, it’s likely that some software or background process is causing the issue. This method allows you to troubleshoot more effectively by narrowing down potential causes and enabling you to identify and remove any conflicting software that could be triggering dimming.
17. Use Third-Party Software for Brightness Control
If none of the tips has worked in troubleshooting the screen dimming issue on your PC, it wouldn’t be a bad idea to use third-party software for enhanced brightness control. The apps that I would recommend you check out are f.lux and Display Turner.
With a wide range of customization features such as the ability to adjust brightness based on the time of the day and reduce the blue light exposure, they can amp up your viewing experience big time. So, give they a chance to win you over.
