I've had the CX-A5200 and MX-A5200 combo for a couple months audio-only while I was building out my theater. Very happy with the sound quality, and had no gripes - until today, when I received my Optoma 6050 projector. I attempted to hook up my NVidia SHIELD to my CX-A5200 and display through the projector... and thus far haven't gotten it to work.\n\nI can see the NVidia logo when the device boots up, but then no picture once it's done with booting. I can hear the "click" of menus when I use the controller, but no video.\n\nI've connected the projector HDMI cable directly to the SHIELD, and got a picture. I also connected the SHIELD's HDMI cable to the projector and got a picture, so I don't think it's either cable. \n\nI've tried HDMI 1 and 2 outputs on the CX-A5200, and neither has shown a picture. I have also tried connecting the SHIELD to several different AV-IN ports with no luck. I also swapped out my SHIELD for another one attached to my TV that I know works, and no joy there either.\n\nHave I got a defective CX-A5200, or is there some hidden setting I haven't had to deal with being audio-only all this time?
