Hey all, I have an Apple TV2, an Onkyo SR508 amp and a Optoma HD65 projector. Now when I connect ATV to my projector using HDMI it outputs 720p no prob. However when I connect my ATV to my AMP and my AMP with my projector, both also with HDMI, I can only get 480p. One last strange thing is that when ATV is booting, the first apple logo is in 720p. Seems like something in my amp is maken my ATV output a lower resolution. Amp works fine with my XBOX360 and digital TV box. Anybody know about a way to fix this?
