How to Stop Computer Screen from Flickering: Easy Fixes

Some people suddenly see their computer screen shaking, blinking, or turning strangely bright. This problem can disturb work and cause significant eye strain, making tasks difficult to complete. Many users search for how to stop computer screen from flickering. In this guide, we first explain simple reasons behind the issue and then provide clear fixes.

Part 1. What Screen Flickering Is And Why It Happens

Screen flickering occurs when the screen brightness changes very swiftly and goes erratic. Plus, this unstable brightness usually appears as quick blinking or sudden dimming flashes. It occurs when the display receives uneven signals or refreshes at irregular intervals. Older CRT displays show flicker because low refresh rates cause rapid brightness fading.

This fading occurs before each refresh cycle, producing noticeable pulsing across the screen. Modern screens flicker due to faulty tuning, weak connection, or unstable backlight control. Sudden changes in how images load can also interrupt smooth brightness across frames. Understanding these causes helps you identify early signs and learn how to fix screen flickering.

Common Signs and Symptoms of Flickering Screen

• Rapid Blinking: The screen often flashes on and off repeatedly, distracting one all the time.
• Wavy Image: Parts of the screen are distorted, or they become waves, frequently.
• Flicker Lines: Horizontal or vertical lines appear and move over the screen.
• Brightness Shifts: Display brightness changes, making parts of the screen appear lit.
• Temporary Blackouts: The screen goes black for seconds before returning, disrupting workflow regularly.

Part 2. Ultimate Fix for Computer Screen and Monitor Flickering

Screen flickering can be annoying when you are doing essential tasks. Below, you'll learn how to stop flickering screen by checking hardware and system settings:

Method 1. Check the Monitor Cable

It is important to check the monitor cable because loose connections can cause the screen to flicker. A damaged or worn cable can interrupt the signal and create blinking or unstable images. Make sure the cable is firmly inserted into both the screen and the computer ports.

Gently tilting the cable can help you detect internal faults that may trigger flickering. Using a high-quality HDMI or DisplayPort cable also helps reduce signal loss and improve overall display stability.

Method 2. Update or Reinstall Display Drivers

Update or reinstall display drivers to resolve flickering by restoring stable image signals. Display drivers manage the communication between the GPU and the screen, so stable performance depends on them working correctly. Corrupted or outdated drivers can disrupt timing, resolution, or refresh rates, which often leads to flickering. Understanding how to fix screen flickering usually begins with keeping your display drivers updated, which is featured in the steps below:

Step 1. Look for the "Device Manager" through the Search menu from the taskbar.

Step 2. To initiate, click the downward arrow beside "Display adapters" to right-click on your desired driver and opt for the "Update Driver" option.

Step 3. Next, choose "Search Automatically For Drivers," and Windows will find the updates automatically. Restart your PC after the update installs so the changes take effect.

Method 3. Roll Back Your Display Driver

If your screen flickers after a recent update, rolling back the display driver may help. This restores a stable driver version and fixes a signal that causes black flashes. Flickers also often appear due to bugs in new drivers, allowing you to address the "how to stop monitor flickering" issue. Go through the guide below to learn how to roll back your display driver:

Step 1. Initiate by opening "Device Manager" and expanding the "Display adapters" section. Right-click on your graphics card and select "Properties" from the menu.

Step 2. Navigate to the "Driver" section and choose the "Roll Back Driver" button.

Step 3. Choose a reason for rolling back, then press "Yes" to continue. Finally, restart your computer to apply the changed settings and check if the screen stops flickering.

Method 4. Adjust Screen Refresh Rate

You can also adjust the screen refresh rate to stabilize images by changing how many frames appear each second. A low or unsupported rate can cause visible flicker and overall display instability. Choosing a supported option such as 60 Hz or 144 Hz reduces strain and improves clarity. This adjustment is an essential step in understanding how to fix screen flickering. Follow the guide below to change your refresh rate:

Step 1. Head to the "Display settings" by right-clicking within an empty desktop area.

Step 2. Upon accessing it, locate and click the "Advanced Display Settings" option.

Step 3. Look for the section labelled "Refresh Rate" where you need to choose a higher value from the available options.

Step 4. After selecting the new rate, a pop-up will appear, where you need to click "Keep Changes" to confirm.

Method 5. Malware Scanning

Malware scanning removes harmful software that interferes with display settings and the graphical process. Harmful programs can change system configurations, overload the CPU or GPU, and trigger repeated screen redraws. They may also corrupt drivers and force constant reloads that create flickering effects. This step becomes essential when learning how to stop a computer screen from flickering, especially when other fixes do not work, as follows:

Step 1. Launch "Windows Security" or your installed antivirus program from the Start menu.

Step 2. Afterward, press the "Quick Scan" button as you navigate to the "Virus & Threat Protection" section. Next, restart your PC to refresh system processes and fix screen flickering problems.
