I just picked up my HD1000 yesterday. After playing around with it for 8 hours, here are my observations compared to my Panasonic AE700:
Much better real-world contrast. Scenes now have great depth, a 3D look -- something that was sorely lacking on the AE700.
Sharper. I was never a big fan of Panny's smoothscreen technology.
Much brighter in "best" mode. While the AE700 could be made bright, the blown-out colours in such a mode made it unwatchable. The HD1000 can be both bright and have high colour fidelity. Of course this comparison was not a side-by-side, as my AE700 has 2000 hours on it, but from memory. FWIW.
No vertical banding!!!
I see some RBE. It's infrequent, and it's just a small nuisance (so far). I didn't feel fatigued after watching for 8 hours yesterday.
I don't remember reading anyone posting about the "vertical location" feature of this projector. While it may not be a physical vertical lens shift, it definitely works that way! I tried this feature while projecting a Windows desktop, and didn't notice any deterioration in picture quality. I think this is a nice bonus feature. I can move my 80" diagonal image about 6" up or 6" down.
Note regarding sharpness:
If you have this proj hooked up to an HTPC via HDMI, and want no interference from the proj in terms of sharpness/edge enhancement, then you must set the sharpness setting to -2. Yes, the range goes down to -5, but that only adds to the confusion. I did a test by viewing very fine text on a Windows desktop and confirmed that the "purest" look came at sharpness -2, which seems to turn off any edge enhancement. When changing the sharpness to -3 or lower, I can definitely see edge artifacts creep back in, giving the text a false sense of sharpness.
Note to Canadians:
I bought this proj from a brick-and-mortar dealer in Toronto, and he says the warranty on it is 2 years...a Canadian thing he said. There was no warranty information in the box itself (nor taped to the side).
