To change the resolution:

1. Right click your desktop, a list appears.

2. Left click on the "properties". "Display properties" window should appear.

3. Click on the "settings", at the top right corner of the "display properties" window.

4. Now you can adjust the resolution by the slide bar titled "Screen area".

5. When you have chosen the resolution (for example 1024 by 768) click ok.
If there's a problem with the new resolution
it will soon return to the original setting if you don't do anything.

Some, usually older, computers display the higher resolutions incorrectly.
