Came late back to this thread to read:
The price went down, and so did the technical knowlegde of recent buyers Most complaints are coming from people who either didn't know what they were buying or don't know how to use it.
Thanks for that, it's real constructive info. I re-read the thread from where some of the "less-glowing" comments were posted, and in each case the spirit of the post was to provide useful info or to share personal impressions of this display. Sounds like if we don't drink a gallon of the kool-aid our opinions don't matter. Marginalizing someone else's viewpoint is the tactic of a bully, usually on the internet and rarely face-to face.
Now, constructively, to the poster that asked about SD content on this set: I'd say that my DirecTV PQ for SD (HR22 to an SC-05 to the 6020) does seem to be OK, but there's quite a bit of variation depending on the programming. When the display is set for more "pop", I've seen SD look pretty funky. At "normal" settings (like the D-Nice cal.) there seems to be more accurate SD. Honestly, though, I think you'll find yourself seeking out HD content much more often because it looks SO good on this display.
