1] Ensure wallpaper resolution and aspect ratio
This is the first thing you need to check since incorrect resolution and aspect ratio will certainly bring the problem to your monitor. Let’s say that your monitor has a resolution of 4K and you are using a 1080p image, which carries 1920*1080 pixels. On the other hand, if your monitor has a 16:9 ratio and you use an image of something else, you will certainly find this problem.
To check the image resolution, right-click on the image and go to Properties. Then, switch to the Details tab and find the Height and Width or Dimensions.
On the other hand, if you want to check the aspect ratio of your monitor, you must find the resolution. For that, open the Windows Settings panel and go to System > Display > Scale & layout > Display Resolution.
Then, check the following chart to find the aspect ratio:
| 2560×1080 pixels | 21:9 |
| 2560 x 1600 pixels | 16:10 |
| 1920 x 1200 pixels | 16:10 |
| 2560 x 1440 pixels | 16:9 |
| 1920 x 1080 pixels | 16:9 |
You need to download the image accordingly.

2] Choose correct fit for desktop background
Some images may get blurry if you choose an incorrect fit for the desktop background. Also, if one image is working fine with FILL, it doesn’t mean all the others will work the same way. You must tweak this setting to find the optimum one.
For that, open the Windows Settings and go to Personalization > Background > Choose a fit for your desktop image. Expand the drop-down menu and choose the correct fit.

3] Set the original resolution and scaling
If you are using anything but the original resolution or scaling, there is a chance of getting this problem – no matter which image you use as your desktop background. To set the correct monitor resolution and scaling, press Win+I to open the Windows Settings first. Then, go to System > Display.
Head to the Scale & layout section and find the Scale menu. Expand the drop-down list and choose 100%.
Then, expand Display Resolution, and choose the original resolution of your monitor.
In case you don’t know, you can choose the “Recommended” resolution, which is generally the original monitor resolution.
4] Turn off wallpaper compression using Registry
If you are using a JPG image as your wallpaper, you must know that Windows 11 will compress it, and this is called Wallpaper Compression. Whether you use an image from the given themes or an external image, it will do so.
That is why you should follow these steps to disable wallpaper compression in Windows 11. First, open the Registry Editor and navigate to this path:
HKEY_CURRENT_USER\Control Panel\Desktop
Double-click on the JPEGImportQuality REG_DWORD value and set the value data to 100. Click the OK button and restart your computer.
Note: The default value is 85. If you want to set the original value, open the same settings and set it as mentioned.
5] Install, update, reinstall graphics driver
There are more than one scenario that might arise at times.
First, let’s assume that your graphics card has stopped working and you removed it. If so, your wallpaper will certainly look pixelated. This problem can be solved by reinstalling a working graphics card.
Second, let’s assume that you don’t have a graphics card, but you are using a 4K or wide-angle monitor. If so, there is a chance of getting this problem.
Third, if you do not have a graphics driver even though you have installed a graphics card, you may find the aforementioned issue. In such cases, you must install the driver.
Fourth, if you haven’t updated the graphics driver for a very long time, you will get this issue. You must update your graphics driver to get it fixed.

6] Switch to HDMI
There are so many types of monitor cables, such as VGA, DVI-D, HDMI, etc. If your monitor has an HDMI port, it is always recommended to use it instead of VGA, DVI-D, or Type-C.
As VGA uses analog signals, there is a very high chance of getting pixelated or blurry images even with a very high-resolution wallpaper. That is why it is always suggested to opt for HDMI instead of anything else.
