Hi, I was recently discussing the differences between EDTV and HDTV projectors. He has an old infocus EDTV projector with a native resolution of 852x480. He is contemplating upgrading to a 1280x720 full HDTV projector. He asked me a question about it and I did not have a good answer so I got curious about it. He was wondering how detectable the difference is, the thought being that seating distance and the size of the projected image would have a large impact on how sharp the image would look. At almost double the number of pixels making up the image, I have to believe that the difference would be signfigant for HDTV content. I do imagine that there is a cut-off at some screensize/seating distance combination where the difference is insignfigant, and other combos where it is very obvious. The particular's of my friends situation is to have the seating at about 12 feet from the screen and for the screen to be in the 80"-100" range. It is difficult to know when to upgrade sometimes, things can be so subjective in this industry that it is hard to seperate the hype from the real deals. As I said before I can't imagine the image not looking better on an HDTV projector...but will it go from "ok" to "spectacular" or will it go from "spectaular" to 'a-little-better-than-spectacular"? Anyone have any suggestions? I found a couple of articles talking about it refering to 42" plasma's but nothing really about large projected images. Thanks!
