I recently bought a Dynex Mini-DVI to Video cable and used a yellow composite cable to connect my 13" Macbook white to the TV. It wasn't working so I was messing around with some of the options and I think I moved the menu bar to the small display under Arrangement Now whenever I plug in the mini-dvi cable, I have no mouse or menu bar displaying on my Macbook. And the TV still shows nothing. Everything is normal when the mini-dvi is not attached, but when it is, I have no mouse arrow. I'll worry about displaying my computer on the TV later: How can I get the Display settings to default?
