Solved Wallpaper quality is low

For the longest time I have noticed when saving wallpapers from the internet or photoshop and setting them as a desktop wallpaper it always creates "artifacts". Artifacts are small pixels forming around outlines and such in an image.

When on the internet the pictures on crystal clear. I can't understand why when I set a wallpaper the quality drops? When I open the picture in a photoviewer they are still crystal clear. It's when I set them as a wallpaper is when they turn to crap.

I have an example below. The left side is a screenshot of the desktop when I apply the wallpaper. I split the wallpaper down the middle and merged a clean version so you can see a half and half of what I am talking about.

Left = Pixelated / Right = Crystal Clear

Are the pictures you are saving greater than or equal to your screen resolution?

This happens when you try and use an image that is a lot smaller than your set screen resolution, Windows has to stretch the image to make it fit correctly.

After some research I have learned the following.


Windows 7 and 8 compress wallpapers in JPEG format. When they compress them it takes a massive quality hit. Now that I am saving as PNG the wallpapers are crystal clear.
