My Intel Mac won't recognize my new Viewsonic 22" wide display, so in the display preferences I'm only offered 4:3 screen resolutions. It did recognize my old 19" wide and offered 1440x900 just fine, but it won't work with this one. Back when I was getting my iBook to successfully span its screen, I seem to remember a utility that would force a certain screen resolution and I'd like to find that again.
