I am a teacher and am considering purchasing an ipad. I would like to be able to project what I am doing on the ipad onto the screen at the front of the room, however, the projector doesn't have wireless capabilities. I can connect my pc at the front of the room to the projector, and was wondering if there was any way in which I could use that as a type of relay, so that my pc pick up the signal from the ipad and send it directly to the projector through the wired connection. Thanks.
