12" powerbook has 4/3 screen, how to change resolution to widescreen for external?

Hey guys. I'm planning on getting a cheap 12" powerbook off eBay. The only thing that's holding me back is that it's not a widescreen lcd. I want to buy an external monitor anyways, but I want a widescreen external monitor. Is there any way to set the resolution on the powerbook to a widscreen one?

Thanks a lot.

Yeah...the Displays pane in System Preferences will let you choose any supported resolution for the connected displays.

Most likely, though, it will automatically configure the second display.
