I have a ipad 2, and recently did a presentation with keynote, using a projector. It worked very well. I have a co-worker who has an ipad 1, he also has keynote. We tried hooking up my hdmi cable and apple adaptor onto our projector, and also a flat screen t.v., and cannot get an image from keynote from his ipad 1. We switched over to my ipad 2, and it worked o.k. Please let me know how to get this to work on his ipad 1. Thank you.
