2. Select System and then Display.

3. Scroll down and click on “Advanced display settings.”

4. Click on “Display adapter properties for Display 1.”

Display dimming is an essential feature of Windows 10 that helps conserve battery life and reduces eye strain.

Remove Latest Windows 10 Update

If you’re experiencing issues with your computer screen brightness since the latest Windows 10 update, you might want to consider removing the update. To remove the latest Windows 10 update, follow these steps:

Step 1: Open the Start menu and click on the Settings icon.

Step 2: Click on the Update & Security option.

Step 3: Click on the Windows Update tab and select Update history.

Step 4: Click on Uninstall updates.

Step 5: Find the latest Windows 10 update and click on Uninstall.

If removing the update doesn’t solve the issue, there are other solutions you can try. For example, you can adjust the screen brightness manually, disable the auto-dimming feature, or use third-party software like Dimscreen or MiniTool Partition Wizard. In some cases, the issue might be related to a hardware problem, so it’s worth checking your monitor or laptop screen’s brightness settings in the user manual. Whatever the reason, there are plenty of methods and fixes to help you get your computer screen brightness back to your preference.

With display dimming, you can adjust the brightness of your screen to match the lighting conditions of your environment.

import win32api

def set_brightness(value):
win32api.SetDeviceGammaRamp(win32api.GetDC(0), value)

# Usage
set_brightness((128, 128, 128))

This code sets the brightness of the display to a medium level by passing a tuple of RGB values (128, 128, 128) to the `set_brightness` function. You can modify the values to adjust the brightness level as per your preference.

Note that this code only works on Windows systems and requires the `pywin32` library, which can be installed using pip. This is just a simple example, and a more sophisticated tool for display dimming would require additional features such as user interface, automatic adjustment, and persistence across reboots.

Use Power Troubleshooter

If your Windows 10 display keeps dimming and you’re not sure why, the Power Troubleshooter is a helpful tool to diagnose and resolve the issue. Follow these steps to use it:

Step 1: Open the Power Troubleshooter tool by clicking on the Start menu and typing “troubleshoot” in the search bar. Select “Troubleshoot settings” from the list and then scroll down to “Power”.

Step 2: Click on “Run the troubleshooter” and the tool will start diagnosing the problem. If it detects any issues, it will provide instructions on how to fix them.

Step 3: If the troubleshooter doesn’t find anything, you can try adjusting the power settings manually. Go to “Settings” > “System” > “Power & Sleep” and change the options under “Screen” to your liking. You can also turn off the auto-dimming feature entirely.

Chances are, your screen is dimming due to adaptive brightness control, a hardware issue, or changes in your environment. With the Power Troubleshooter and these methods, you can fix the problem and get back to enjoying your PC without any warning about the dim screen.

Update Graphics Card Drivers

To update your graphics card drivers, first open the Device Manager by typing “Device Manager” into the search bar and selecting it from the results. Expand the “Display adapters” section and right-click on your graphics card. Select “Update driver” and follow the on-screen prompts.
If updating your drivers doesn’t solve the dimming issue, try adjusting the brightness feature by pressing the Windows + I keys to open the Settings window. Select “System” and then “Display.” From here, you can adjust the screen’s brightness manually or enable the “Change brightness automatically when lighting changes” option.
Another option is to download a program like Dimscreen or MiniTool Partition Wizard to adjust brightness levels.
If your laptop screen keeps dimming, check for any hardware issues or environmental changes that may be affecting the sensors. You can also adjust the power settings under “System” and “Power & Sleep” to prevent dimming under certain conditions. If nothing seems to work, consult the user manual or contact the manufacturer for further assistance.

Turn Screen’s Power Saving Mode Off

To turn off Power Saving Mode and keep your screen’s brightness consistent, follow these steps:

1. Click the Start button and click on the Settings gear icon.
2. Click on System and then go to Power & sleep.
3. Scroll down to Related settings and click on Additional power settings.
4. Choose the power plan you are currently using and click on Change plan settings.
5. Click on Change advanced power settings.
6. Look for Display and click on the plus sign to expand the options.
7. Look for Display brightness and make sure it’s set to 100% for both “On battery” and “Plugged in” options.
8. Click on Apply and then click on OK to save the changes.

If your screen’s brightness still changes despite turning off Power Saving Mode, it could be caused by another reason such as a hardware issue or adaptive brightness control. Try other fixes such as adjusting your environment or changing the input power. If nothing works, it’s best to seek professional help or contact your manufacturer for assistance.

Calibrate Display Color

Calibrating your display color can make a huge difference in the quality and clarity of your screen. To calibrate your display color on Windows 10, go to the Start menu and open the Settings app. Click on “System,” then “Display,” and scroll down to “Advanced display settings.” From there, click on “Color calibration” and follow the on-screen instructions.

Make sure to adjust your display settings based on the tasks you’ll be performing. For games and fun activities, you may want to increase brightness and saturation for a more immersive experience. On the other hand, if you’re working in an environment with changes in lighting, you may want to reduce brightness to avoid eye strain.

Keep in mind that some laptops, like the Lenovo ThinkPad, may have their own brightness feature or sensors that automatically adjust screen brightness based on ambient light. If your screen’s brightness keeps changing without warning, this may be the case. In that method, you can change brightness settings to adjust brightness manually or disable the auto brightness feature altogether.

Modify Windows Registry

To modify the Windows Registry and adjust your Windows 10 display dimming settings, follow these steps:

1. Press the Windows key + R to open the Run dialog box.

2. Type “regedit” into the field and hit Enter.

3. Navigate to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7” in the registry editor.

4. Find the “Attributes” value and double-click it.

5. Change the value data to “2” to enable the option to change the display brightness.

6. Save your changes and close the registry editor.

After modifying the registry, you should be able to adjust your screen’s brightness using the buttons on your laptop or in your system settings. If your Lenovo ThinkPad or other laptop screen keeps dimming, this method may help you increase the brightness or reduce it as needed. Keep in mind that changes in your environment or tasks may also affect your screen’s brightness, so you may need to adjust it accordingly.

Turn Off Monitor’s Auto-Dimming Feature

To turn off your monitor’s auto-dimming feature in Windows 10, follow these steps:

1. Go to the Start menu and click on the settings icon (gear icon).
2. Click on System.
3. Click on Display.
4. Scroll down and click on “Advanced display settings”.
5. Click on “Display adapter properties for Display 1”.
6. Click on the “Monitor” tab.
7. Uncheck the box next to “Enable adaptive brightness”.
8. Click “Apply” and then “OK”.

Once you have completed these steps, your display will no longer automatically adjust its brightness based on changes in your environment. This can be particularly helpful for users who are playing games or doing other fun activities on their computer, as auto-brightness changes can be distracting or interfere with gameplay. Whatever your reasons for wanting to turn off auto-dimming, following these steps should help you keep your screen’s brightness at a consistent level no matter what.

Turn Off Windows Game Mode

To turn off Windows Game Mode, go to the game bar by pressing Windows key + G. Click on the Settings button and turn off Game Mode. This should stop Windows from automatically dimming the screen’s brightness.

It’s important to note that if you have auto-brightness turned on, your screen’s brightness may still change based on environmental changes. In this case, you can go to System Settings and adjust the screen brightness manually.

If you’re still experiencing dimming issues, there could be other reasons why your screen’s brightness is changing. Check out our guide on Windows 10 Display Dimming Solutions for more tips and tricks on how to increase or reduce brightness.
