How do I find out out my computer's resolution?
PC Instructions: Right click on your desktop, click on Properties, then click the Settings tab at the top of the Display Properties window. Below your screen resolution will be displayed (i.e. 1024 x 768 pixels)
Check the list on this page to see what your screen format is. (i.e. for 1024 x 768 pixels, you would download the Standard wallpaper size.)
When applying the wallpaper as your desktop background make sure the position setting of your background is set to 'Fill Screen' or 'Stretch'. You can adjust this on the drop down menu to the left, in Display Properties.
