Tile is usually used on smaller images, hence the name Tile such as kitchen tiles. Tile does not stretch or shrink the image.
With Windows 7 there are three ways to stretch or shrink a desktop image.
- Fill - Fill will fill the screen which in essence crops off the portion that is stretched beyond the screens resolution.
- Fit - Fit will fit the entire image to screen while keeping image proportions, which may create black areas at the top/bottom or left/right.
- Stretch - Stretch will stretch the image and possible warp the image if it does not match the resolution of the screen.
There is always the option of editing the image to match the resolution of your screen.
