Table of contents:

  1. Change Screen Resolution
  2. Check if Your Drivers Are Compatible
  3. Set DPI Size
  4. Update monitor drivers
  5. Change monitor refresh rate
  6. Update Windows

Solution 1 – Change Screen Resolution

Wrong screen resolution is an issue in the most cases. Some updates may disrupt your screen resolution, and changing it back to normal, should fix things up. If you don’t know how to change the screen resolution, here’s how to do that.

  1. Right click on Desktop and choose Personalization
  2. In the down left corner, click on Display
  3. Click on Adjust ResolutionComputer screen pixelated and freezes
  4. Choose your resolution and click OK

Solution 2 – Check if Your Drivers Are Compatible

If resolution changing doesn’t help, first thing you want to do next is to check if your video drivers are compatible with Windows 8.1, if they’re not, uninstall them and install the compatible ones. Here’s how to do that:

  1. Press Windows key + R and type devmgmt.msc in the run prompt.
  2. Expand the Display adapters section, right-click your adapter and then uninstall itndows 10 pixelated video
  3. Restart the computer, let Windows 8 detect the driver and install by itself and check if it fixes the issue.

If updating your drivers don’t help, then you probably have some issues with your DPI(dots per inch) settings. The next solution will show you how to solve all DPI issues.


Solution 3 – Set DPI Size

Setting the DPI size to a smaller percentage will decrease all items size on the display, which will definitely help you if your screen is pixelated.
The easiest way to change DPI is through Display Settings:

  1. Go to Settings > System > Display
  2. Now, go to custom scaling, and you’ll see a screen like this:Pixelated screen Windows 7

Now, choose one of these three options and save the changes:

  • Smaller – 100% = 96 DPI (Pixels/Dots Per Inch)
  • Medium – 125% = 120 DPI (Pixels/Dots Per Inch)
  • Larger – 150% = 144 DPI (Pixels/Dots Per Inch)

Solution 4 – Update monitor drivers

If your GPU drivers are up to date, we’re also going to make sure your monitor drivers are good. Although monitor drivers cause issues less often, it’s still possible. Especially if you recently got a new monitor, or installed a new version of Windows 10.

Here’s how to check if your monitor drivers are up to date:

  1. Go to Search, type devicemngr, and open Device Manager.
  2. Expand Monitors.
  3. Right-click your monitor, and go to Update driver.My laptop screen is pixelated
  4. Let your computer find new drivers for your monitor.
  5. If there are any new drivers available, let the wizard install them.
  6. Restart your computer.

Solution 5 – Change monitor refresh rate

If the monitor refresh rate is set to a wrong one, there’s a chance your screen will become pixelated. Here’s how to change that:

  1. Right-click the Desktop and go to Display Settings.
  2. Go to Advanced display settings
  3. Under Related settings, go to Display adapter properties
  4. Go to the Monitor tab and select another refresh rate from Screen refresh rate:Computer screen pixelated virus
  5. Click OK

Solution 6 – Update Windows

I don’t have to tell you to keep your Windows 10 computer up to date. Updating your computer brings many benefits, and possibly resolves some issues (although some problems may be caused by updates, but that’s a story for another time). So, check for updates, and maybe the solution for your problem will just come to you.

To update your computer, simply go to the Settings app > Updates & Security, and check for updates.
