Methods to fix a distorted, flashing, stretched or skewed image on display screen

A distorted monitor or laptop does not always require a professional’s intervention. There are simple DIY troubleshooting methods you can try.

Try the below methods to fix laptop or desktop monitor flashing or distortion issues:

1. Check computer’s cables and connections
2. Reboot computer
3. Reset monitor to default
4. Push degauss button
5. Remove all connected devices
6. Adjust screen resolution
7. Update computer drivers
8. Reinstall drivers
9. Replace video card
10. Replace the monitor

Method 1: Check computer’s cables and connections

Distorted images on laptop or desktop monitor can occur if the cables are damaged, broken, burnt, or loose. So, begin by checking the cables and connections of your computer.

Ensure all the cables including the video or VGA cable are plugged in to the device properly. Chords should not be bent, lose, or defected.

Method 2: Restart your computer

Restart after updates or software installation re-initializes the drivers and hardware parts. Restart can fix many logical and physical problems including faulty display of monitor.

Method 3: Reset monitor to default

With continuous usage over the time, the screen settings may get changed. Reset the monitor to its default settings. Press the menu or settings button on the desktop or LCD monitor. This opens the main menu. Now, select ‘Restore Factory Settings’ option.

The menu setting options vary with brand and model. For instance, Dell monitors usually have ‘Factory Reset’ while Samsung monitors show ‘Reset all’ option.

Note: If you don’t find any reset option, turn off your monitor by pushing the ‘Power’ button. Next, disconnect the monitor from the computer. This should reset the monitor settings to default.

Method 4: Push degauss button

Degaussing refers to eliminating a magnetic field. Electromagnetic buildup can sometimes distort the display picture. This is common with older CRT (Cathode Ray Tube) monitors.  If you are using CRT monitors, try degaussing to fix the distorted display problem.

Degauss method may vary with monitors as below:

• CRT monitors have a ‘Degauss’ button in front. Push it to remove magnetism effect on the monitor.
• Power off and Power on your monitor. This can degauss some monitors automatically.
• In some monitors, you have to open the screen menu. Click on the horseshoe shaped icon to degauss.

Degaussing is only limited to CRT and not required in LCD and Plasma monitors.

Method 5: Remove all connected devices

Sometimes external devices connected or near your computer build up electromagnetic field that leads to overlapping, scrambled or distorted screen.

Try to fix display screen by keeping away any speakers, mobiles, or other electronic devices from your computer.

Method 6: Adjust screen resolution of monitor

If you are facing widescreen monitor, stretched, pixelated or blurry display on monitor or laptop, adjust the screen resolution.

Note: The path to screen resolution option may differ depending on the manufacturer and model of your desktop or laptop.

Method 7: Update computer drivers

Update your computer driver, if above methods don’t fix distorted image on monitor.

Steps to update the device driver:

• In the search box type, device manager.
• Select Device Manager.
• Under Display adapter, right-click on your graphic card and click Update driver.

• Select Search automatically for updated driver software.

• Select Update Driver.

You can also download the drivers directly from the manufacturer’s site. Make a note of the make and model of your desktop monitor. Visit the support page of the manufacturer’s website and follow their instructions.

Method 8: Reinstall drivers

If updating graphic cards don’t help, reinstall them. Reinstalling fixes most of the video cards related problems such as distorted image, overlapping, or corrupt display screen.

Steps to uninstall the driver follow the below steps:

• Right click on My Computer/ This PC.
• Click on Manage > Device Manager.
• Double-click Display Adapters from the list.

After uninstalling graphic drivers, reboot your computer. Windows will automatically reinstall the drivers.

Method 9: Replace video card

Faulty graphics card can also cause distorted, flashing, or skewed display on monitor. Replace video card and check if it fixes distorted display problem.

If your computer is very old, you may have to replace the complete motherboard. This is because the old computers used AGP technology, which may not be found today. Modern graphics cards run on the PCIe interface.

Method 10: Replace the monitor

This is the last resort. When all the above methods fail, including replacing your video card, then change the computer monitor.

Here we suggest to first test with a different monitor. If the problem is resolved, opt for a new monitor.

If the screen problem continues, it’s a hardware issue that needs repair by a professional. Contact the manufacturer or the authorized service center of your computer or monitor.
