Coworker has an iBook G4 (A1134) that is not lighting the screen when it boots. I want to check if it's the screen (or part thereof) or the GPU chip on the logicboard by plugging the Mac into a monitor. However, I didn't realize it has a mini-port yesterday. So, I brought my mini-DVI to DVI adapter from home assuming it would work. It's the one they give you for the 12" PowerBook G4. But the "mini" end is seriously way too large to fit into the port on this iBook. Is there a difference between a mini-VGA to VGA adapter and a mini-DVI to DVI adapter? The mini-VGA adapters seem to be cheap on eBay but I don't want to buy one of these only to find out it won't work. Anyone know anything about this?
