When the desktop computer screen keeps flashing, you can troubleshoot and solve the problem by following these steps: 1. Check and adjust the refresh rate
1 Windows system: Right click on a blank space on the desktop and select "Display Settings"- Scroll down to "Advanced Display Settings" and click on "Display Adapter Properties"- In the "Monitor" tab, adjust the "Screen Refresh Rate" to a suitable value, usually recommended to be set to 60Hz or higher, depending on the monitor specifications.
2 MacOS system: Go to "System Preferences" and select "Monitor"- Check if there is an option to adjust the refresh rate (not all macOS devices support adjusting the refresh rate), and if so, make the adjustment. 2、 Check and update graphics card drivers
1 Windows system: Right click on "This Computer" or "Computer" and select "Manage"- Select "Device Manager" in the left navigation bar- Expand "Display Adapter", right-click on the graphics card device, and select "Update Driver"- Select 'Automatically search for updated driver software', or go to the official website of the graphics card manufacturer to download and install the latest version of the driver.
2 MacOS system: Go to "System Preferences" and select "Software Updates"- Check and install all available system updates, including updates to graphics drivers. 3、 Check and fix connection issues
1. Check cable connections: - Ensure that the cables (such as VGA, HDMI, DP, etc.) between the monitor and the computer are securely connected and not loose or damaged- Try replacing the connecting wire to eliminate the possibility of a circuit malfunction.
2. Check interfaces and connectors: - Clean the dust and dirt on the monitor interface and computer interface to ensure good contact- If using peripherals such as KVM switches, please check if they are working properly and try connecting the computer and monitor directly to eliminate the possibility of peripheral failures. 4、 Check and eliminate power interference
1. Check power equipment: - Ensure that the power plug is securely plugged into the socket and try using another socket or power cord for testing- Check if the power transformer is too close to the monitor and chassis. If so, move it away from the monitor and chassis.
2. Check power stability: - If possible, use a voltage stabilizer or UPS (uninterruptible power supply) to ensure power stability. 5、 Check and eliminate other sources of interference
1. Magnetic field interference: - Try to avoid placing the monitor near strong magnetic field devices such as mobile phones, speakers, etc.
2. Software Conflict: - Attempting to close or uninstall recently installed software that may cause screen flickering- Update all installed software to the latest version to fix possible compatibility issues. 6、 Check the monitor itself
1. Try connecting to another computer: - Connect the monitor to another computer for testing to determine if it is an issue with the monitor itself.
2. Check monitor settings: - Check if there are any settings options related to screen flicker in the monitor menu, such as automatic adjustment, color mode, etc., and make appropriate adjustments. 7、 Seeking professional assistance
If none of the above methods can solve the problem, it is recommended to contact the technical support of the monitor manufacturer or seek help from professional technicians. They can provide more detailed troubleshooting steps and necessary repair services.
