I want the setting that allows the Mac OS to change the resulation. I think it's called "Plug N Play for 20 inch displays" or something like that it allows for 1024 x 768, 800 x 600, and 640 x 480, it also allows me to go into "none-recommend" settings and chose 60 herts which is what I need to drive my new monitor*.

* I can do other refresh rates but only for about a minute(to give me time to change to 60 herts I guess)
