I'm a recent HT guy, having bought a setup last winter consisting of an HD CRT 47" RPTV and surround sound system. Here for anyone who is curious: www.geocities.com/jason_flynn
Anyhow, I've done pretty much everything possible to tweak it out except Duvetyne and a full greyscale job and as a result of razor-sharp focus I have a very slight moire issue. What's this have to do with LCD? Well, I'm moving into a new home perhaps as soon as a year, and want to take the FPTV plunge. My budget will likely put me into an AE100 and the screendoor issue is interesting.
With a high def CRT setup you will eventually get moire when the clarity and focus gets to 100% perfect and you display 480p or higher. Funny thing is that the fix is the same as for 480 line LCD screendoor: slight defocus.
Anyway, for those of you grappling with a budget LCD unit understand that you are not alone. Furthermore, as much as I enjoy the crystal clarity of my CRTs I am really wishing for a true "big screen" experience, hence the desire to move up to FPTV. FWIW, be thankful that digital FPTV is a more forgiving animal than CRT, as I can attest that tweaking this thing and keeping it at 100% can be a chore at times, although I do find the technical aspects fascinating and enjoyable ... kind of akin to keeping a high performance car in top tune.
