It sounds like you would like sticking with DLP 720P and need very low db's so the best deal is an Optoma h-78dc3....and yes it is better than the Pany/Sanyo lcd's with better contrast....and an overall punchier picture.It is in fact an H-79 with 100 less lumens.They are discontinuing this model because of near future cheaper 720p and more expensive 1080p pj's that are coming out.You can get one of these for around your budget with a free 400.00 extra bulb and a two year warranty.This is what I ...
Therefore, we may summarize the characteristics of each projector as follows: First, the Sanyo PLV-Z4 delivers a razor sharp, smooth, stable image that is comparatively low in noise. Color is rich and beautifully saturated. Black level is solid enough to produce an entirely satisfying image, but deep blacks, as in a starry black sky, are not as black as they are on the H79. Overall, the most noticeable shortcoming on the Z4 in comparison to the H79 is in the separation of shadow details in dark scenes.The Optoma H79 produces excellent contrast and dynamic range, with very deep black levels, brilliant whites, and good detail separation in dark scenes. Color performance rivals that of the Z4, with the Z4 maintaining a subtle edge. The H79's most notable shortcomings relative to the Z4 are a comparative softness in the image, and more noise and dithering that tend to impart a slightly grainy texture to the image.So--which projector would we buy? They are both great projectors, and both have their faults and limitations. Each will appeal to a certain type of user. Nevertheless, we can say this: the Sanyo PLV-Z4 really shines with bright films, animated films, and most HDTV. It outperforms the H79 with highly saturated, high contrast material like Shrek and Austin Powers, by rendering a sharper image with less digital graininess. The overall result is an image with a smooth, filmlike quality.
Apparently you can test for banding:"Vertical banding is an artifact that appears in some LCD projectors. When it is present, it is most apparent in smooth mid-tone scenes such as a gray sky. It appears as subtle vertical bands, typically about one inch thick, running through the entire image. One can test for its presence by using 50 IRE and 60 IRE mid-tone gray fields available on test/calibration discs." (from projector central)I know Avia has these screens, as I used them to set greyscale. I'm not sure what other disks have them.
Isn't that one pretty spendy?
The Sony VPL-VW100 and the Hitachi Cp-sx5600 are the ones I'm most familiar with, plus one by JVC. I don't know much about them, except that they're very very good but very expensive. Liquid Crystal on Silicon is a great technology, but way out of my price range.I'm not sure how soon I'll buy, but I'm leaning towards making the move from my SD/ED DLP to the Panasonic PT-AE900U. I've always preferred DLP to LCD, but the price to performance ratio of the new LCD models is compelling. My main desire is ...
