How To Fix A Blurry Screen (Top 6 Fixes!)

There are few things more frustrating and disorienting than trying to use a blurry screen. My husband and I have come across this issue a few different times now while working from home. Each time, a different fix ended up being the solution. Here’s how to fix it.

How To Fix A Blurry Screen

To fix a blurry screen, first exit ‘Safe Mode’, inspect the display cable, and set the monitor to the maximum resolution. If the issue persists, adjust ‘ClearType’ text and check for display scaling issues. As a final measure, update and reinstall the graphics driver.

So, what causes a blurry screen in the first place? What gives? As it turns out, there are 6 primary causes:

  1. Computer is running in safe mode
  2. Input cables are damaged or not firmly secured
  3. Monitor resolution set too low
  4. ClearType settings have not been calibrated
  5. Scaling issue due to improper display properties
  6. Missing or outdated device drivers

Often times your issue may be due to one or a combination of these leading causes. Not a computer nerd? Unsure of where to even begin?

Read on for further step-by-step instructions and supportive images to get your monitor clear and crisp today!

Step 1: Exit Safe Mode

Sometimes your PC may reboot in Safe Mode without you even realizing it.

Safe Mode will automatically activate if it your PC crashes more than once during startup. It is typically used to make computer repairs if you suspect your device is infected with malware.

You may also activate it if specific software has not been installed correctly and you wish to troubleshoot your system.

When activated, Safe Mode loads a standard video driver at a low resolution. This causes your desktop and programs to look different and may be the cause of your blurry screen.

Clues that you are in Safe Mode include larger than normal icons, out of place icons, and your PC sound not working.

To cancel Safe Mode, use your desktop search bar to locate the System Configuration tool. In the tool, select the Boot tab and uncheck the Safe boot box if it is selected. Click Apply and then Restart your computer.

System Configuration exit safe mode

What if Safe boot box is NOT selected, but you still suspect your PC is in Safe Mode?

In this case you will need to head to your original PC menu at startup.

For Windows 7 or below, you will need to press F8 in one-second intervals during the restart process. Once the Advanced Boot Options menu is activated, select the Start Windows Normally option.

For Windows 8 and 10, in the Shutdown menu hold the Shift key simultaneously as you click Restart. Then select the Troubleshoot page and choose Advanced options and then Startup Settings. Once you restart your computer, you will now automatically enter the Startup Settings screen. Finally, select return to your operating system and your PC should load normally from here.

Step 2: Inspect the display cable and confirm a secure connection

Often the display cable is to blame. Whether you are using HDMI, DisplayPort (DP), VGA or DVI the first step is to inspect the display cable for any visible damage.

HDMI, DisplayPort, VGA and DVI display cables

Examine the heads of each cable and inspect the pin connectors. Make sure that none of these connectors are bent, damaged or missing.

  • VGA: 15-pin connector
  • DVI (single-link): 18-pin connector
  • HDMI (standard): 19-pin connector
  • DisplayPort: 20-pin connector

Next, make sure there is a secure connection made on BOTH ends of the display cable.

Even the smallest break in connection can cause issues. Push both display cable ends in firmly.

If your screen is still blurry, try using a different type of display cable than the one you are using. If your screen becomes clear your display cable is the issue.

Step 3: Set Monitor To Max Resolution

In most cases it is recommended that you use your monitor’s native resolution. The native resolution of your monitor is simply the maximum number of pixels your monitor can display.

Low monitor resolution settings can cause image distortions that manifests as a blurry screen.

To update your resolution, use your desktop search bar to locate the Display settings. Under the Display resolution section click the drop down menu. From here, select the maximum resolution setting available (this should also be designated as Recommended).

To ensure you are getting the most out of your monitor, you should also optimize your monitor’s brightness while you are at it. Often times you can spend big money for a high resolution monitor – take advantage of it!

Step 4: Adjust ClearType Text

At this stage, if most of the display looks fine but you are still observing blurry text, you may want to re-calibrate your ClearType.

ClearType is Microsoft developed software that improves the readability of text on your display. It is enabled by default in Windows 7, 8, and 10.

Often times when your text has a granular, uneven look you can easily fix this by adjusting your ClearType.

To adjust your ClearType, use your desktop search bar to locate Adjust ClearType text in the Control Panel. From here make sure the Turn on ClearType box is checked and select Next.

Adjust ClearType text

Then simply follow the instructions and tell ClearType what font displays appear best. ClearType will do the rest!

Step 5: Check For Display Scaling Issues

First and foremost, how do you know if you are encountering display scaling issues?

Common display scaling problems include distorted icons, apps, and toolbars. Various desktop items may appear too large or too small relative to other items. And finally, text may appear blurry.

Adjusting your resolution settings is one display scaling issue we have already addressed.

Some other common display scaling fixes include:

  1. Log out and then log back in to your Windows account. When you do this, Windows automatically resets the display configuration. Often times this can fix your scaling issues right away.
  2. Allow windows to try and fix the problem by turning on Fix scaling for apps. To do this type Fix apps that are blurry into your search bar. In the Advanced scaling setting box toggle Let Windows try to fix apps so they’re not blurry to ON.

  3. Make sure you have the recommended size set for text, apps and other items. To check this type Display in the search bar and navigate to the Scale and layout section. Then use the drop down menu to select 100% (Recommended).

Step 6: Update And Reinstall Graphics Drivers

The first and simplest thing to do when it comes to your device drivers is to check for software updates.

Software updates are by far one of the best ways to fix bugs. If you do not frequently update Windows you can run into display driver compatibility issues. If this is the case there is a good chance this is causing the problem!

Check for any pending software updates by going to Settings and selecting Windows Update.

Update device drivers

Sometimes the graphics driver is specifically to blame. To test this, first try to update the graphics driver directly.

Once again head over to the search box and this time enter Device Manager. Right-click on the name of your graphic device, and select Update Driver.

Update your graphics driver

If this does not fix the problem try uninstalling the graphics driver by right-clicking and selecting Uninstall.

Then simply Restart your computer – Windows will automatically attempt to reinstall the graphics driver during startup.

Gaming Monitor Looks Grainy – Troubleshooting Steps

Attention all of you gamers out there. If you have tried all of the steps above but your monitor is still grainy, the issue likely exists within your NVIDIA control panel.

Let’s review how to fix the three most common NVIDIA control panel issues.

Activate Full RGB Dynamic Range

Limited RGB range settings can cause a grainy screen. To fix this you will need to change your RGB settings to full.

  3. Next, select the Output dynamic range drop-down menu and then select Full (0-255).
  4. Click Apply.

This will enable the full RGB range of applications on HD displays that support it.

Disable Anti-aliasing (AA)

Anti-aliasing (AA) is a post processing filtering technique that attempts to minimize distortions. When turned on, the anti-aliasing effect typically makes text look poor.

To disable anti-aliasing (AA):

  1. Within the NVIDIA Control Panel navigation tree pane click Manage 3D Settings.
  2. Select Antialiasing – Mode and then select OFF in the box next to it.

Reset NVIDIA graphics card to factory settings
