Basically I have an Optoma GT1080E projector hooked up to an Onkyo 5.1 receiver. I have my Xbox one, 4K amazon fire tv and zgemma hooked up to this. Sound works through the receiver fine but for some reason the picture is either a mess or worm show at all, on any device. If I plug the device directly into the projector then they show fine but through the Onkyo receiver the picture can’t be displayed. But what’s stranger still is the projectors OSD menu displays fine if I call that up. I’ve attached an example of what’s being displayed.
