7 Ways to Fix Windows Screen Flickering
Screen flickering is a common issue for Windows users, often appearing as irregular flashes or changes in brightness. This article provides effective methods to fix screen flickering and improve your experience.
I. Common Causes of Screen Flickering
1). Incorrect Display Refresh Rate Settings:
If the monitor's refresh rate is set incorrectly, it can cause the screen to flicker.
2). Graphics Driver Issues:
Outdated or corrupted graphics drivers can lead to screen flickering.
3). Software Conflicts:
Certain applications or background processes may interfere with screen display.
4). Hardware Connection Problems:
Loose or damaged cables can also cause screen flickering.
5). Power Issues:
Unstable power supply or electrical interference may lead to flickering.
II. Methods to Fix Windows Screen Flickering
1. Adjust Monitor Refresh Rate
Right-click on an empty area of your desktop and select "Display Settings".
Scroll down to the bottom of the page and click on "Advanced display settings".
Choose "Display adapter properties", then go to the "Monitor" tab.
Select an appropriate refresh rate from the drop-down menu, then click "OK".
2. Update Graphics Drivers
Outdated or corrupted graphics drivers can be a cause of flickering. It is recommended to use Driver Sentry to automatically detect and update drivers, saving time and avoiding the risk of downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry. Once installed, open the software and click "Scan".
After the scan is complete, the software will display which drivers are missing or need updating. Find the graphics driver in the results list and click the "Update" button.
After the update is complete, it is recommended to restart your computer to ensure the updated driver takes effect.
3. Check for Software Conflicts
Open Task Manager (by pressing Ctrl + Shift + Esc) and check for multiple programs or processes running in the background. Close unnecessary programs, especially those consuming a lot of resources.
Ensure all installed software is updated to the latest version, as outdated software may conflict with the operating system or other software.
Use the "Startup" tab in Task Manager to disable unnecessary startup items, then restart your computer.
Sometimes, antivirus software may conflict with other programs. Try temporarily disabling your antivirus software to see if the issue is resolved.
4. Check Hardware Connections
Ensure all cables between the monitor and computer (such as HDMI, DisplayPort, VGA, etc.) are securely connected. Unplug and re-plug these cables to ensure they are not loose.
Try replacing the cables to see if the problem is resolved.
If using any video converters or adapters (e.g., HDMI to VGA adapters), check if these devices are functioning properly.
Connect the monitor to a different port on the computer to see if the issue persists.
5. Perform a Power Cycle
Turn off the computer and then turn off the monitor.
Unplug the power cords from both the computer and monitor, and wait a few minutes to ensure all internal circuits are fully discharged.
Reconnect the power cords and ensure all connections are secure.
Turn on the monitor first, then the computer, and check if the issue is resolved.
6. Adjust Power Management Settings
Go to the Control Panel and select "Power Options".
Make sure to select the "High performance" mode instead of the "Power saver" mode.
Click "Change plan settings" > "Change advanced power settings", expand the "Display" option, and ensure the screen-off time and sleep mode settings meet your needs.
Under "PCI Express", set "Link State Power Management" to "Off" to prevent screen flickering.
7. Test Another Monitor
Connect the computer to a different monitor to see if the problem still occurs. If the new monitor has no issues, the original monitor may be faulty.
Ensure the latest graphics drivers are installed when using a new monitor.
When testing with another monitor, use the same cables to determine if the problem is not caused by the cables.
Enter the new monitor's settings menu to adjust brightness, contrast, refresh rate, and other options to ensure that the monitor settings do not cause flickering issues.
Screen flickering is a common problem, but the steps above can effectively resolve most issues. If these methods do not solve the problem, it is recommended to seek professional technical support for further diagnosis and resolution.
