I don't know much about it, but watch out as an increasing number of laptops are now coming with Displayport connectors rather than HDMI.
HDMI is slowly dying as far as computers are concerned - make sure your projector can handle both, or else you have a way of converting the outputs from the laptop to DVI (assuming the projector has an DVI input....)
One thing I have found while helping a friend with his film shows is that using HDMI to output video to a projector while using analogue sound output to an audio mixing desk can cause serious synch problems with the sound. You need to rehearse the show beforehand to make sure you don't get the same problem
