Monitor flicker can be caused by a few different things, but they all have one thing in common: they’re super annoying. The first thing to check is the cable connecting the monitor to the computer. If it’s loose or damaged, it can cause flickering or a loss of signal.

Another possible cause is an outdated or corrupted graphics driver, which is basically the software that lets your computer talk to your monitor. If the driver is outdated or corrupted, it can cause monitor flicker and other display issues.

Sometimes, the flicker can be caused by incorrect display settings, like an incorrect refresh rate or resolution. And, of course, electrical interference from other devices or appliances can cause monitor flicker too.

One of the most common causes of monitor flicker is a loose or damaged cable connecting your monitor to your computer. It’s like having a phone with a bad connection, and it’s equally frustrating.

The first thing to check is whether all the cables are securely plugged in and tight. A loose cable can cause the screen to flicker or go black intermittently. So if you find a loose cable, simply unplug it and plug it back in again to make sure it’s securely connected.

Keep an eye out for any frayed or bent pins as well, since they can cause flickering too. If a cable is damaged beyond repair, you’ll need to replace it. Once you’ve tightened all the cables and made sure they’re in good condition, give your monitor a test to see if the flicker has disappeared.

If it’s still flickering, there may be another cause, so move on to the next troubleshooting step.

3. Update Graphics Drivers

An outdated or corrupted graphics driver is one of the most common causes of monitor flicker, but it’s an easy problem to fix. To get started, visit the website of your graphics card manufacturer and look for the latest driver for your card.

Download and install the new driver, following the instructions provided by the manufacturer. This will replace the old driver with a new, updated one that should take care of the flickering issue. Sometimes, you may need to uninstall the old driver before you can install the new one.

It’s a bit of a process, but it’s worth it to get your monitor back to normal. Once you’ve updated your driver, test your monitor again to see if the flicker has disappeared.

4. Adjust Monitor Refresh Rate and Display Settings

What is Refresh Rate

Most operating systems have a display settings menu that lets you adjust the refresh rate and resolution of your monitor. If your monitor’s refresh rate is set too low, it can cause flicker. So try increasing the refresh rate to a higher value.

You’ll see the difference in the smoothness of your display. Also, make sure the resolution of your monitor matches the display and computer settings. Sometimes, adjusting these settings can take some trial and error, but it’s worth it to get your monitor working properly.

5. Reset the Monitor to Factory Settings

If you’re still experiencing monitor flicker after trying other troubleshooting steps, resetting your monitor to its factory settings can be a helpful last resort. It’s a particularly useful step if you’ve made several adjustments to your display settings and aren’t sure what’s causing the issue.

To reset your monitor, go to the monitor’s menu and look for the reset option. The reset option may be in a different location depending on your monitor’s make and model, so check the user manual if you’re not sure where to find it. Follow the on-screen instructions to reset your monitor to its default settings. Remember that resetting your monitor will erase any custom settings you’ve made, so you’ll need to readjust them later.

If your computer monitor flickers on and off during startup, it’s important to investigate the cause. One possible cause is a loose cable connecting your monitor to your computer, so check all cables to ensure they’re securely plugged in.

If that doesn’t help, try booting your computer in safe mode to see if the problem persists. If the flickering disappears in safe mode, the cause could be an outdated or corrupted graphics driver.

You can try updating the driver to see if that resolves the issue. If the flickering continues even in safe mode, it could be due to hardware problems, like a failing backlight or power supply.
