In any scenario, you will be experiencing reduced quality of your viewing experience and you will most likely want to get it fixed. These anomalies on your screen can indicate anything from a loose connection to a potential hardware failure.

If the lines persist, it might be necessary to examine the monitor’s settings or update its drivers. Regular maintenance, such as verifying cables and updating software, often resolves these glitches.

Troubleshooting Your Flickering Monitor

What Makes My Monitor Flicker?

A few things can cause your monitor to flicker. Loose cables are a common culprit. So is an old or bad display driver. If your monitor is old, it may just be nearing the end of its life. Let’s dive into each of these and see how we can fix them.

Check Your Cables

A loose cable is often the easiest fix. Make sure the cable connecting your monitor to your computer is secure at both ends. If you have multiple cables, try each one to see if it makes a difference. Sometimes, a cable might look fine, but it could still be damaged. Try a different cable to see if that fixes the flicker.

Update Your Display Driver

Sometimes, an outdated or faulty display driver can cause your monitor to flicker. To fix this, you need to update the driver. Here’s how:

  1. Press the Windows key + X and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click on your display adapter and select Update driver.
  4. Follow the on-screen instructions to finish the update.

If that doesn’t work, you can try uninstalling the driver and letting Windows reinstall it automatically.

Other Possible Causes

If loose cables or outdated drivers aren’t the issue, here are some other things to check:

  • Refresh Rate: Make sure your monitor’s refresh rate is set to a value it supports. You can usually change this in your display settings.
  • Resolution: Your monitor might flicker if the resolution is set too high or too low. Try changing the resolution to see if that helps.
  • Electromagnetic Interference: Sometimes, devices like speakers or other electronics can cause interference. Try moving them away from your monitor to see if that fixes the flicker.
  • Hardware Issues: If none of the above solutions work, there could be a problem with your monitor’s hardware. In this case, you might need to take it to a repair shop or consider replacing it.

  • Secure connections and updated drivers are vital for optimal monitor performance.

Diagnosing Monitor Flickering Issues

When a monitor flickers with horizontal lines, it may signal hardware or software issues. However, before seeking professional help, there are steps to check and possibly fix the problem at home.

Initial Checks and Basic Fixes

First, inspect the cable connections between the PC and the monitor. Loose or damaged cables can often cause flickering. Make sure the connections are secure and, if possible, try different cables to rule out damage. Also, giving the monitor a gentle look for any signs of damage helps. Sometimes a monitor is on its way out and flickering is the first clue.

Software and Drivers Troubleshooting

Outdated or corrupt display drivers may lead to monitor flickering. To tackle this, one should update the graphics drivers. In Windows 10, open Device Manager, click on ‘Display adapters’, and select the option to update the driver. If the issue started after a recent update, consider rolling back to an older driver that worked well.

Hardware Troubleshooting

If software fixes don’t clear up the flickering, the problem might be inside the monitor itself. It could be the LCD panel or internal components. In such cases, unless one possesses technical repair skills, it might be safer and more cost-effective to take the monitor to a repair shop instead of opening it up.
