Do you have a computer monitor that flickers? If so, you’re not alone. Many people experience this issue. There are several things that you can do to try to fix it. In this blog post, we will discuss How to Fix a Computer Monitor that Flickers. We will also provide steps on how to perform each fix.
The most visible and yet often most underappreciated part of any computer system is the monitor. It’s where your movies play, your spreadsheets are displayed, and where your gaming adventures come to life.
The slow but sure development and improvement of LCD and LED monitors over the last twenty years has put top-quality displays within reach of even the most limited budgets, to the point that the older CRT monitors are all but extinct from the marketplace.
Monitor flicker, unfortunately, hasn’t followed CRT monitors onto the ash-heap of history. Although the new monitors are far more reliable than the old CRT technology, it is still possible for them to develop a flicker.
But don’t panic– if your computer monitor does start flickering, it doesn’t automatically mean it’s curtains for that piece of hardware. It could just mean a driver refresh is required or that you or someone else previously made changes to the Windows configuration.

The Reason Why A Computer Monitor Flickers
The display on your computer screen is not static, even though it looks like that. The image is constantly redrawn and erased at a rapid rate that your eyes can not perceive.
A modern screen can give a refresh rate of up to 100 times per second. The action is referred to as the refresh rate and it is measured in hertz. If you look at the specifications of the monitor, you will see a number such as 60Hz, 100Hz, or something else.
The number is used to indicate how many times a refresh occurs per second. The screen can be refreshed 60 times per second on a 60Hz monitor. A refresh rate of 100 times per second is achieved by a 100Hz monitor.
The quicker the refresh, the easier it is for the display to react to changes. 100Hz computer monitors are ideal for gaming where the display changes constantly, and 100hertz TVs are so popular because of this outcome.
People are different in how sensitive they are to hydration. Some people can see a perfectly stable screen if they run their monitors as slow as 30Hz. The refresh will be detected by other people and they will see it flickering.
What To Do If Your Computer Monitor Is Flickering
1. Cables For Monitors Should Be Checked
Some people don’t use the screws to hold the ends of the cable securely in place. The ends of the connectors must be securely held in place. The cable may be malfunctioning if securing the connection doesn’t fix the flicker. If you can get a spare one, swap them out to see if that resolves the problem.
2. Power Check
The power cable needs to be checked that both ends are secure. A screen can sometimes flicker, and a buzzing sound accompanies this if a power cable is loose.
3. Display Settings Should Be Checked
Check the display settings to make sure nothing has changed if you have recently updated your graphics driver. Click on a blank space on the desktop and select your graphics card from the control panel. Depending on the manufacturer of the video card, the menu option will be different.
You can change the resolution by clicking on it in the graphics control panel. Select the flickering monitor in the options and make sure the refresh rate is at least 60 frames per second.
If you have a 100Hz monitor, you should set it to that. If you have any changes, save them and retest them.
You can also check through Windows 10 Settings.
- Navigate to Settings and click on System.
- Scroll down and select Advanced display settings.
- Display adapter properties text link in the center box
- Select the Monitor tab and check the refresh rate from there.
Your Graphics Card Needs To Be Checked
There are issues with the graphics card that can cause the monitor to flicker. These situations are not normal, but they are a possibility.
The issue is not your graphics card if you have multiple monitors and only one screen acting up. If you only have one monitor that flickers, it is worth checking out the hardware and connections.
Dirt and dust do not accumulate on the surfaces of the graphics card. Make sure the cooling fan is working and that fans are turned on when they should.
Speedfan and similar programs can be used to monitor the temperature of your card, as overheating is a prime cause of most graphics card issues. It’s possible that it isn’t your graphics card that’s causing the flickering.
Make Sure You Check The Monitor
The monitor itself could be the final cause of your computer flickering. Changing the port you are using will allow you to try out the monitor. If you use a DVI connection, it’s best to use the DisplayPort or VGA output. You may need to borrow another monitor to test if nothing changes.
Take your monitor to another computer and see if it works. If the monitor flickers on another computer or with a different hardware connection, then it’s likely that it’s reached the end of its life.
Unless your monitor is very high-end and expensive, it will likely cost more to repair than to buy a new one.
