ok here's my setup in my theater. mac mini 2012 hdmi out to a pioneer elite sc-35 which handles the hdmi switching to my jvc rs45 projector. if I do it this way the picture has dot crawl in red on the screen. also I loose audio from the hdmi output after a few seconds. if I switch inputs to say hdmi on the reciver to hdmi 3 which is the mini the sound will come one for about 5 seconds. if I hook the mini directly to the projector the picture is perfect with no dot crawl. I also tried display port to hdmi instead of just the hdmi. I am running osx 10.81 my net is down from storm so I haven't updated yet. any ideas? this is my third mini that has run my theater so i'm pretty familiar with them. I tried various hdmi inputs on my receiver and a different hdmi cable as well. thanks for any help!
