what about the powerbook macbook pro resolution adjustment?
Mmmm, okay, let me explain my earlier snide comment.
A CRT works by spraying a screen with an electron beam gun. The gun is moved around by EM fields, basically. The screen itself doesn't really have a fundamental resolution; it can more or less display as high a resolution as you can get -- which is limited by how accurately you can control the electron beam.
An LCD doesn't work anything like this at all. An LCD has a fixed grid of pixels that are basically like colored glass that can change color. They can change from opaque to transparent, and they handle in three colors so that you can come up with whatever color you want. Then you pass
white light through the grid and, just like a projector, you see the pixels that are transparent as light and the pixels that are opaque as dark.
BUT, the resolution of the grid is always the same. Think of it like a checkerboard. You can only put the pieces in the squares. There's nowhere else to put the pieces. And there are only so many squares.
You can *reduce* the resolution, as you do on your Powerbook, and it will attempt to simulate the lower resolution on your screen (so you can make 800x600 on a powerbook). The screen still has the same number of pixels, but it interpolates the image onto them.
But you can never go higher than the actual native resolution. This is no less true of the Powerbook than your Gateway or of any other LCD. Every single LCD works this way.
