Screen flickering problems can be solved by updating drivers, adjusting refresh rates, checking external devices, and turning off visual effects. First check and update the graphics card driver, go to the device manager or official website to download the latest version; secondly adjust the display refresh rate to a suitable value, such as 60Hz or 120Hz; then check whether the external cables and docks are normal; finally turn off unnecessary visual effects and energy-saving settings to improve stability.

The screen blinking or blinking is a fairly common problem on Windows 11 display, especially when using a new system. It may be caused by drivers, hardware compatibility, refresh rate settings, or external devices. The good news is that in most cases this problem is solved and does not require immediate repair.

Check and update the graphics card driver

Many screen flickering problems are actually related to the graphics card driver. Windows 11 has higher requirements for driver compatibility. If the driver is too old or does not match, it can easily lead to display exceptions.

• Go to Device Manager → Expand Display Adapter → Right-click on your graphics card model (such as Intel, NVIDIA, or AMD) → Select Update Driver.
• You can also go to the official graphics card website to download the latest version to install it instead of relying on Windows to automatically update it.

If you have just recently upgraded to Windows 11, it may be installed with a universal driver by default, so it is recommended to manually change it to the official recommended version.

Adjust the display refresh rate settings

Sometimes the screen flickers because the refresh rate is not set correctly, especially at high resolution. For example, if a monitor that should have been running at 60Hz is wrongly set to another frequency, it will cause slight jitter or flicker.

• Open Settings → System → Display → Scroll to the bottom and click "Advanced Display Settings".
• Select the appropriate value in the Refresh Rate option (usually 60Hz, or 120Hz or 144Hz if it is a high refresh rate).
• If you are not sure which one to choose, you can try 60Hz first to see if it improves.

Some monitors support multiple refresh modes, remember to try different options to see which one is the most stable.

Troubleshoot external equipment and cable problems

If you are using an external monitor, the problem is most likely not the computer itself, but the connection cable or monitor settings.

• Try replacing the HDMI or DisplayPort cable to see if it still flashes.
• Plug and unplug the cable and make sure the interface is not loose or oxidized.
• If you use a dock, try to bypass the dock and connect the monitor directly to the test.

Sometimes unstable USB-C docking station power can also cause display abnormalities, especially those cheap third-party products.

Turn off unnecessary visual effects and energy saving features

Windows 11 has some animation and energy-saving features enabled by default. Although these look beautiful, they can sometimes cause abnormal displays.

• Open Settings → System → Power → Select the High Performance Power Plan to try.
• At the same time, you can click "Change schedule settings" in "Power Options" → "Change advanced power settings" → turn off the power saving options in the "PCI Express" and "Display" related items.

In addition, Windows' "smooth effects" may also affect some old graphics cards:

• Settings → System → About → Advanced System Settings → Performance Options → Uncheck "Show Visual Styles in Window".

Basically these are the methods. You can troubleshoot one by one, usually the problem lies in the driver or refresh rate settings. If small details that are not complicated but are easily overlooked are handled, most flickering problems can be solved.
