My wife tried to use a LCD projector with her 4100 for a Powerpoint presentation at a meeting but couldn't get the projector to work. I wasn't present, but my son was along and he thought that the projector was hooked up properly. I don't have much information but I was wondering if any of you had any thoughts as to what may be the problem. I intend to take it to work on Tues. and try it with our projector at work. In the meantime, do any of you have any suggestions? Appreciate any help. Thanks.
