That's the exact same behavior my laptop, running windows 7, has when connected to an HDTV (multiple monitors work fine, and it's never messed up my desktop, as well). There's no adapter needed, either, which seems to be what that point was getting at - my highschool, which had standardized on mac laptops, was constantly plagued by difficulties finding adapters when using computers to run projectors. They were constantly lost or misplaced, and using multiple generations of macs often meant that the adapter we first found wasn't the right type.
