This is my first experience with "DisplayPort." I'm used to DVI and HDMI, but not this puny port on the side of my new Macbook Pro. So, what is it? Is this a standard DisplayPort, or a "Mini" DisplayPort, on the unibody Macbook Pro? I need to hook up a projector to the Macbook Pro. I don't think the projector has DisplayPort, in fact I don't know any peripherals that do. So, do I need to buy an adapter to go from my DisplayPort to DVI? Do I lose anything when going from DisplayPort -> DVI, i.e. a signal or quality downgrade? Finally, if an adapter is necessary to use external displays, why didn't it come with my laptop? Annoying if every lappy purchaser needs to by a damn adapter to use the external display port. I appreciate Apple moving the envelope (e.g. Firewire, DisplayPort, new buttonless trackpad, unibody construction), but the purpose is defeated if I need to make another visit to the Apple Store to buy yet another piece to use something as basic as the external display function. Any other information or advice you have is appreciated.
