I have a optoma H31 projector, that according to spec can display high definition. It has DVI and component inputs. I have it currently hooked up using component from my Onkyo receiver. I would like to connect HDMI sources such as Chromecast or Apple TV to the receiver so I can use the projector. The receiver only takes component or composite input. Is there a converter that would work in this situation? Are there anythings I need to watch out for?
