Hi all I recently bought a Optoma 4K projector and when hooked up to my Yamaha on a signal from Netflix that is 4K Ultra HD, I get the sound through the system but no video. If I toggle between powering items off and on the signal might come in but eventually gets an error at the bottom that signal lost. Whats weird is if I turn the receiver off, the 4K signal passes through the receiver to the projector and plays but no sound of course! I have checked the receiver to see that it is in Mode 1 for 4K but at a loss. There is a firmware update but it doesn't specify it's going to help with this issue.
