CS2 filter don't fit screen

When I try to choose a filter in CS2 I can't see all of the screen to put the numbers in. Is there some way I can make this fit the screen? My Elements filter screen fits ok.
Thanks

Are you using Photoshop at least at the minimum resolution? 1024x 768?

Im not sure. How do I check it and set it if need be?

Right-click on your desktop and Choose Properties>Settings.

You will see a slider marked screen area
