My Denon receiver is the X4400H. I have the 4k BenQ LK970 PJ. I am using the Sony X800 BD player. I cannot get my receiver to allow my 4k HDMI to work through it. If i go straight from my projector to the X800 it says 4k/30p with just video. But with the PJ 4k HDMI to the receiver, then to the BD player theres no video. With HDMI 2 on the PJ, blu ray movies say 4k/20p. But 4k movies say 1080p because HDMI 2 is not a 4k HDMI. Sorry if this is hard to understand can you give me an idea what might be wrong?
