The menus are being cut off, or I can’t see the entire screen?

Many OLDER webs were set up for a standard resolution of (800 by 600 pixels).
This "defacto" standard has been abandoned with the advent of newer flat screen
monitors. (CRT monitors are gradually phasing out).

The entire Boise State University - COBE web is OPTIMIZED/BEST                   
viewed at a MINIMUM screen resolution of 1024 X 768 pixels

What screen resolution am I using currently?

To change your computer's screen resolution:
