Why is my macbook wallpaper so blurry/ low quality

Hi Kgorethz,

Thanks for your post to Apple Support Communities. We understand you have some questions about setting a desktop wallpaper on your MacBook Air.

You mentioned trying a few different photos, which seemed to all have an issue. We'd first recommend making sure they are of a size to fit your desktop and not require the system to zoom in in order to stretch the photo to fit.

When you set a system standard provided wallpaper photo, do you notice the same blurriness?

Here are our tips to customize desktop pictures on your Mac:

If your photos aren’t shown, they might not be in the expected file format—JPEG, PICT, TIFF, PNG, or HEIC. Use Preview to open your photos and save them in one of the formats. If your photos are shown but look fuzzy, try using larger ones, such as 1024 x 768 pixels.

Take care.

Unless the original of that is of the screen size or larger (number of pixels, such as 1600x1000), you will never get a clear picture if you try to enlarge it - the pixels will be fuzzy. Check your screen size and then pick images with those dimensions or larger (you can always reduce the size).
