Adjust the refresh rate to the recommended setting for your monitor.
Step 3: Update Your Graphics Drivers
Outdated graphics drivers can cause compatibility issues, leading to flickering. Update your graphics drivers to the latest version.
Step 4: Disable and Re-enable the HDMI Port
Disable the HDMI port on your connected device, then re-enable it to reset the connection.
Step 5: Check for Firmware Updates
Check for firmware updates on your monitor and connected device, and apply any available updates.
Step 6: Try a Different HDMI Port
If you’re using a multi-monitor setup, try switching the HDMI cable to a different port on the monitor or connected device.
Step 7: Reset the Monitor to Its Default Settings
Reset the monitor to its default settings to restore the factory settings and potentially resolve the issue.

What is the flickering issue on my monitor, and why is it happening?
The flickering issue on your monitor is a common problem that occurs when there is a discrepancy between the refresh rate of your computer’s graphics card and the monitor’s display. This can cause the screen to flicker or dim, making it difficult to view. The issue is often more pronounced when watching videos or playing games, as the constant change in brightness can be distracting and even cause eye strain.
The problem is usually caused by a mismatch between the HDMI handshake process, which is the communication between the graphics card and the monitor to establish the optimal display settings. When the handshake process fails, the monitor may default to a lower refresh rate, causing the flickering effect. Other factors, such as a faulty HDMI cable, incorrect display settings, or outdated graphics drivers, can also contribute to the issue.
How do I determine if my monitor is set to the correct refresh rate?
To check if your monitor is set to the correct refresh rate, you’ll need to access your graphics card settings. For Windows users, you can do this by right-clicking on an empty area of the desktop, selecting “NVIDIA Control Panel” (or “AMD VISION Engine Control Center” for AMD users), and then clicking on “Adjust desktop size and position.” From there, select the “Refresh rate” dropdown menu and ensure it’s set to the recommended rate for your monitor.
The recommended refresh rate for your monitor can usually be found in the user manual or on the manufacturer’s website. For most monitors, the recommended rate is 60Hz, but some high-refresh-rate monitors may require a higher setting. Make sure to select the correct rate that corresponds to your monitor’s capabilities to prevent the flickering issue.
What if I’ve tried adjusting the refresh rate, but the flickering persists?
If adjusting the refresh rate doesn’t resolve the issue, it’s possible that there’s a problem with the HDMI connection or the graphics card itself. Try swapping out the HDMI cable for a new one or using a different HDMI port on your computer. If you’re using a multi-monitor setup, try disconnecting the other monitors to see if the issue persists.
Additionally, you may need to update your graphics drivers to the latest version. Outdated drivers can cause compatibility issues that lead to the flickering problem. You can usually find the latest drivers on the manufacturer’s website or through the device manager on your computer.
Can I fix the issue by adjusting the display settings on my monitor?
Yes, adjusting the display settings on your monitor can help resolve the flickering issue. Try adjusting the monitor’s brightness and contrast settings to see if it improves the display. You can also try enabling or disabling features like HDMI-CEC (Consumer Electronics Control) or HDMI-ARC (Audio Return Channel), as these can sometimes interfere with the HDMI handshake process.
However, be careful when adjusting the display settings, as incorrect adjustments can make the issue worse. It’s also important to note that not all monitors have the same settings, so you may need to refer to your user manual or the manufacturer’s website for specific instructions.
What if I’ve tried all the troubleshooting steps, but the issue still persists?
If you’ve tried all the troubleshooting steps and the issue still persists, it’s possible that there’s a hardware issue with your monitor or graphics card. In this case, you may need to contact the manufacturer or a professional for further assistance.
Before seeking outside help, try resetting your monitor to its factory settings and see if that resolves the issue. You can also try using a different HDMI input or a different computer to rule out any issues with the HDMI port or graphics card.
Can I prevent the flickering issue from happening in the first place?
Yes, there are steps you can take to prevent the flickering issue from happening in the first place. When setting up your monitor, make sure to use the correct HDMI input and select the correct display settings. You should also ensure that your graphics drivers are up to date to prevent any compatibility issues.
Regularly updating your graphics drivers and monitoring your display settings can help prevent the flickering issue from occurring.

Is the flickering issue unique to HDMI connections, or can it occur with other types of connections?
The flickering issue can occur with other types of connections, including DisplayPort and VGA. However, it’s more common with HDMI connections due to the complex handshake process involved.
While the issue is less common with other types of connections, it’s still possible for it to occur. If you’re experiencing a flickering issue with a different type of connection, try troubleshooting the issue using similar steps to those outlined for HDMI connections. If the issue persists, you may need to consult the user manual or contact the manufacturer for further assistance.
