Thanks.

It's not a Mac, Jack...

I'd tried right-clicking on the desktop, and that gives me a menu with "Personalize", and that gives me "Display Settings" - but the slide for adjusting that only goes up to1440 by 900 pixels, which makes it a bit bigger, but still nowhere near full screen. If you can find a way to get those numbers bigger, Joe,I imagine that would do the trick. Or perhaps there's something I can do with the TV itself.
