On Vista:

Right click on the desktop

Select Personalize

Then Display settings

And you'll have the option in the bottom right corner of the thing that pops up



It's kinda the same on XP

But instead of personalize, it's properties, you'll find it on there
1. Right click on the dekstop (wallpaper).

2. From the menu, click properties.

3. Click the settings tab.

4. Drag the slider to set your resolution.

5. Select the correct correct quality.



Then click okay!
