I have a Comcast HD DVR that I am looking to connect to two projectors. Neither projector will be on at the same time. The question is, how do I connect my Comcast box to two different projectors using HDMI? I figured I would use a splitter but have possibly run into a problem. One projector is 720 while the other is a 1080p 3D projector. I have been told that the splitter will only display the resolution of the lowest projector? Is that the case and if so is there a way for me to do this at all? If I am able to do this what splitter would you recommend? Thanks to anyone who can help.
