Besides resolution, what should I look for when choosing a wallpaper?

There are three important factors people often overlook:

Aspect ratio compatibility - A 4:3 image on a 16:9 monitor will either crop awkwardly or stretch.

Contrast balance - Wallpapers with too many bright or busy details can make icons hard to read.

Composition - Images with some empty space or smooth gradients tend to look cleaner and more professional.

Sites that curate their collections well - including https://fondecranvip.com/ - often let you browse by style such as minimal, nature, abstract, cars, anime, or dark themes, which helps match your wallpaper to your interface layout.
