Why Does My Screen Lighten Up When I Print Screen?
Have you ever noticed that when you hit the "Print Screen" key on your keyboard, your screen suddenly brightens up? This is a common phenomenon, and it's usually due to a feature built into your graphics card. Here's why it happens and what you can do about it.
The Screen Brightness Boost: A Feature, Not a Bug
The reason your screen gets brighter when you press "Print Screen" is a handy feature designed by graphics card manufacturers like NVIDIA and AMD. This feature, often called "Print Screen Boost" or "Screenshot Brightness Boost", aims to improve the quality of screenshots by increasing the screen's brightness temporarily. This ensures that the captured image is brighter and more detailed, especially in dark or low-light environments.
Understanding the Mechanics
When you press "Print Screen," the graphics card triggers a temporary boost in screen brightness. This boost is applied directly to the display's backlight, making the screen noticeably brighter for a brief period. After you release the "Print Screen" key, the brightness levels automatically return to their previous settings.
Is It a Problem?
For most users, this screen brightness boost is a non-issue. It's a helpful feature that improves screenshot quality, especially when capturing content in darker environments. However, some users find the sudden brightness change uncomfortable or even distracting.
How to Disable Print Screen Brightness Boost
If you're bothered by the screen brightening when you use "Print Screen," you can usually disable this feature in your graphics card settings. The specific steps may vary depending on your graphics card manufacturer and model.
NVIDIA:
- Right-click on your desktop and select "NVIDIA Control Panel".
- Navigate to "Manage 3D Settings".
- Under "Program Settings", choose the option for "Print Screen" or "Screenshot".
- Locate the option for "Brightness Boost" or "Screen Brightness Adjustment" and disable it.
AMD:
- Open the AMD Radeon Software application.
- Go to "Settings" or "System".
- Look for "Screenshot Brightness Boost" or a similar option.

Other Graphics Cards:
If you have a different graphics card brand, you might find similar settings within the manufacturer's control panel.
Troubleshooting and Alternatives
If you're unable to find the specific "Print Screen Brightness Boost" option in your graphics card settings, here are some alternative troubleshooting steps:
- Check for updates: Ensure your graphics card drivers are up to date. Outdated drivers can sometimes cause unexpected behavior.
- Reset settings: Resetting your graphics card settings to their defaults might resolve the issue.
- Use alternative screenshot tools: There are numerous third-party screenshot tools available that don't rely on the built-in "Print Screen" function. These tools often offer advanced features and may not trigger the brightness boost.
Conclusion
The screen brightening when you press "Print Screen" is a feature designed to enhance screenshot quality. However, if you find it bothersome, you can easily disable it in your graphics card settings. Remember to update your drivers and consider using alternative screenshot tools if necessary.
