How do I change the screen size on my laptop?

The screen icons etc are sooo large that I am NOT able to change the screen by right clicking and doing so in preferences. I can't move the pop up high enough to change it!!! I am using Windows Vista. Any help would be greatly appreciated!How do I change the screen size on my laptop?
