...connect through my computer? My camera (Canon SX1) has a yellow white red connection, a standard USB connection and a HDMI connection. Unfortunately, the only similar connections that the projector has is a HDMI but the cable costs a fortune because it is particular to that camera. Is there any software that I can use on my computer so that I can plug the camera into the computer and then stream full screen so that it appears full screen when I plug the computer into the projector?
