If updating your drivers doesn’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.

Although monitoring 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.

While manual updating your drivers is the most popular solution, the recommended way is to update them automatically using a dedicated tool such as DriverFix.

DriverFix automatically update drivers

The best thing about choosing this method is the time saved in looking for the right software. After scanning your device, DriverFix offers a list of compatible fresh drivers.

You can then update not just the monitor driver, but all outdated drivers, either one by one, or bulk.

4. Set DPI Size

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

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)

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.

Bonus: Why is my monitor suddenly pixelated?

Speaking about Windows updates, such files are usually behind a screen that suddenly gets pixelated. Don’t worry, we will explain everything.

Now, a grainy display in Windows 10 is generally triggered when using a non-native resolution to display images on your PC or laptop.

Your device struggles to fill the screen and adds more pixels to keep the image uniform. By rendering at such a large size, individual pixels become distinguishable and make the whole display look grainy or fuzzy.

Now, this is a general definition, but there are particular cases to mention and such is the Windows 10 Update pixelated screen.

If the monitor was working just fine, but suddenly become pixelated after installing a Windows update, it’s clearly an indication of software conflict or incompatibility triggered by the recent changes.

You might want to revert them and check if the display works fine in order to narrow down the list of potential culprits or update your drivers and graphics card adequately.

That’s about it, we hope at least one of these solutions helped you reset the pixelated display back to normal.
