I have a Macbook (2009) and an Epson EX7200 projector, which I use mostly for work presentations. However, since I have it I might as well use it to watch movies at home. I have a great Epson HD screen that I can set up. The projector comes with a USB 2.0 cable I can use to connect it to the Macbook, but in the manual it says the highest quality is obtained with an HDMI cable. I guess I'd need an HDMI to MiniDisplay adapter cable? Is this right? I understand that it won't pass audio through to the projector, but that's fine since I'm going to be attaching external speakers to my computer anyways.
