Why is my Computer Screen Blurry? [9 Ways to Fix]

It is hard to use a computer when it has a blurry screen. The blur monitor can make you feel less enthusiastic on your computer and probably at work.

Here on this page, you will find various tested ways to fix the blurry monitor. These methods worked for me and probably you too.

You may have one or more problems and you need to analyze that. Take the action accordingly.

Let’s get into the subject.

Clean your monitor screen

First things first. Is your monitor screen clean?

The dust on the monitor will cause a blurred screen so you can’t see the screen clearly. You can fix the issue by cleaning it.

Here Linus will get this thing in detail. Watch his video and clean the screen properly. Keep a computer screen cleaner with you and make your PC clean regularly.

If your monitor is clean, then swipe for the next one.

Download and install video card drivers

When you install the new Operating System on your computer, the screen looks fuzzy. This is because they do not have display drivers yet. The Windows OS will download the latest updates on your PC to fix this automatically.

The updates on Windows PC contain the latest stable version along with the drivers that are required on your PC.

In most cases, the Windows operating system will download suitable drivers for you. But when an error occurs by downloading or updating, you need to install the graphic card drivers manually.

Remember, the display drivers, graphic card drivers, and video card drivers are the same. Here you can find different types of drivers on a computer.

If the graphics card drivers are installed on your PC, your monitor screen looks more clear and more natural.

Here is the comparison of the monitor screens with and without graphics card drivers.

The monitor screen looks blurry when the Windows default ‘Scale and layout’ settings are changed.

Windows will suggest the recommended scale and layout settings based on the hardware capability. So if they get disturbed, it looks unnatural.

How to find and fix monitor scaling?

  • Open Settings on your computer
  • Select ‘System’ then the display settings will open on your PC
  • This is what the page looks like.
Display settings on Windows PC

Under ‘scale and layout’, click on the percentage and select default or 100% recommended. Here is a guide to measuring the monitor screen.

Do the same for display resolution. The display resolution varies from monitor to monitor. Choose the recommended resolution that Windows suggests.

Here, my monitor Dell U2412M supports 1920*1200 pixel resolution. So I make it active instead of 1920*1080 or 1920*1050.

And select the display orientation as Landscape but not a portrait or flipped.

Your blurry monitor will be fixed after this.

Turn ON the Windows scaling feature

Click on the advanced scaling settings. Then the page will display.

Under ‘Fix scaling apps’ select the option ‘Let Windows try to fix apps so they are not blurry.’

A step bottom to that, you’ll find custom scaling. Windows don’t recommend this option and I do too.

If you change these settings (custom scaling) previously, clear them to default. The system needs to restart to apply these changes. Here are some tips for you (Windows PC users).

Use DisplayPort or HDMI cables

The display and HDMI cables are more efficient in performance and can transfer digital signals compared to the VGA cables, which transfer data in analog.

However, there is no need to blame the cable in this case. Use the latest technology through which you can get more from it. That’s all I mean. Go with the comparison of cables to find more.

Find the buttons on your monitor and push the menu button to get the options. Then go for display settings and click on ‘Reset display settings.’
