I have a Denon 3910 and a Hitachi 57S715. Is it best to connect through the component input or HDMI? Also if I connect via HDMI should I set the Denon 3910 to 1080i or 720p (the Hitachi outputs either 1080i or 540p)? If I set the 3910 to 720p I would asume the Hitachi converts it to 1080i. Correct?
