I have Yamaha dgx 505 receiver with HDMI capability. I connect my HDTV and Xbox360 with the Yamaha receiver via HTML. But I am having a problem when I connect Xbox360 through the receiver. I am receiving low video quality than going direct into the HDTV, I donât know why? Is it better to connect video direct into the TV, and then audio only to receiver? I will appreciate any feedback, your experience can get me out of the problem.
