This looks like a sweet TV; I used to have a 60" Panasonic rear projection lcd, but we had to get rid of it almost 3 years ago when we started remodeling our house. For about a year and a half I had to live with a 32" lcd 8-/, and for the last year or so the biggest tv in the house has been a 47" lcd. I'm *finally* almost ready to finish putting together the new media room we built during the remodel and was hoping to get at least a 65", this 70" sounds even better
From reading the manual, it looks like it supports 1-to-1 mapping for 1080p inputs with no annoying overscan hiding the edges, which is good; as well as separate calibration profiles for each input, also good.
The manual discusses using ARC on the HDMI 1 input to feed audio to an attached receiver, but it's not really clear on whether it will proxy the hdmi audio from a blueray player or htpc. Ideally, I'd like to attach things directly to the tv so each input device can have its own calibration settings (as opposed to hooking them all up through the receiver and then to the tv on the same input), but I also want the receiver to decode the surround tracks. Some TV's will only negotiate the audio track they can deal with and then feed that to an attached receiver, rather than negotiating one that the receiver can deal with.
So, for someone with tv in hand, if you attach an hdmi ARC compatible receiver to the hdmi1 input on the tv, and then a blueray player to hdmi2, does the receiver get the high quality surround track when playing a disc or does the tv feed it just the stereo track?
