Windows 10 screen flashing or splashing is a common but troublesome problem, usually related to graphics card drivers, system settings, or third-party software. While it may happen on any device, it can be solved in most cases with some simple ways. The following are several common causes and corresponding solutions.

1. Check and update the graphics card driver

Incompatible or outdated graphics card drivers are the most common causes of screen flickering, especially NVIDIA, AMD, or Intel integrated graphics cards.

Solution:

• Press Win X and select Device Manager .
• Expand the display adapter .
• Right-click on your graphics card (such as Intel UHD Graphics, NVIDIA GeForce, etc.) and select Update Driver .
• Select Automatically search for updated drivers .

Tip : You can also go to the official website of the graphics card manufacturer (such as the Intel driver support page, NVIDIA official website or AMD official website) to download the latest driver and install it manually. Use DDU (Display Driver Uninstaller) to completely uninstall the old driver in safe mode and then reinstall it for better results.

2. Turn off the "Hardware Acceleration" function

Many applications (such as Chrome, Microsoft Teams, Discord, etc.) use hardware acceleration to improve performance, but sometimes conflict with graphics card drivers, causing the screen to flash.

How to turn off hardware acceleration:

• Chrome browser :

  1. Click the three dot menu in the upper right corner → Settings .
  2. Go to System → Turn off Using Hardware Acceleration Mode (if available) .
  3. Restart the browser.

• Windows system level settings :

  1. Open Settings → System → Display .
  2. Scroll to the bottom and click Graphic Settings .
  3. Turn off the hardware-accelerated GPU plan (if enabled).

It is recommended to turn off hardware acceleration for suspicious applications one by one to see if the problem is solved.

3. Adjust the monitor refresh rate

Incorrect refresh rates can cause the screen to flicker, especially when external displays are connected.

Operation steps:

1. Right-click on desktop → display settings .
2. Scroll to the bottom → Click Advanced Display Settings .
3. To view the current monitor, click the Refresh Rate drop-down menu.
4. Select the recommended refresh rate (usually 60Hz or higher, such as 75Hz, 144Hz).

If you are using an external laptop monitor, make sure the cable (HDMI/DP) supports high refresh rate.

4. Check for system updates or patch conflicts

Some Windows 10 updates may cause compatibility issues, especially cumulative updates.

Suggested practices:

• Open Settings → Update and Security → Windows Update and install all available updates (new patches may fix old issues).
• If the problem occurs after an update, try:
  • Uninstall recent updates: Settings → Updates and Security → Recover → Fallback to earlier versions (if still within 10 days).
  • Or remove the recently installed KB update in View Update History → Uninstall Updates .

5. Disable Transparent Effects and Visual Effects

Windows 10's visual effects can sometimes cause rendering issues, especially on older devices.

Close method:

1. Open Settings → Personalization → Color .
2. Turn off the transparent effect .
3. (Optional) Right-click "This Computer" → Properties → Advanced System Settings → Performance → Settings → Select Adjust to Optimize Performance or Turn off the special effects manually.

6. Check the hardware problems of the monitor or cable

If the flashing occurs only when the external monitor is connected, it may be loose cables, damaged or the monitor itself malfunction.

Troubleshooting suggestions:

• Replace HDMI/DisplayPort line test.
• Try connecting to another monitor or TV.
• Check if the notebook screen is flashing when it is moving (maybe poor cable contact).

Basically that's it. Most screen flickering problems are caused by the driver or software settings. Priority is given to updating the graphics card driver and turning off hardware acceleration, and 90% of the cases can be solved. If all methods are invalid, consider temporarily creating a new user account test to rule out the possibility of corruption of the configuration file.
