You have - so I take your advice very seriously!!
Because I am really new to this - can you teach (explain) to me why screen cannot exceed 120" when using the LS5.
Also, is the LS3 as good a choice - I notice that the LS3 doesn't have horizontal lens shift but I don't even know what that means of it matters.
I assume that you believe that this so-called Rainbow effect will not be an issue on Chris's screen.
LS-3 and LS-5 are really the same machine with exception of a few features which horizontal lens shift is one. Len shift whether horizontal or vertical allow installation flexibility........if you are installing yourself, you need as much flexibility as possible. Proper placement of the projector can eliminate projection problems, but I for one would never own a projector without horizontal and vertical lens shift.
Don't worry about moire..............I'd worry more about why your sound stinks rather than the fear of moire! IMHO, audio is the most important aspect of movie watching............once again, my opinion and you have to decide for yourself.
120" wide 1.78 screen for the LS-5 is the max manufacture recommended screen size for a reason. Sure, your picture might look great at first, but after 200 hours the lumens degrade quite significantly. A dull image is due to a lack of lumen output............make sure whatever projector you decide upon, you have ample light output as the bulb dims. The biggest problem most posters run into is having too big a screen for their projector and are not happy with their image as the bulb ages............just check out the current JVC threads.
I find movies at the theater quite dim...........so I've chosen to go the 3 chip DLP route with CIH screen. I prefer 18-20 lumens for 2.37 (all lights off), and 30-40 lumens on a 1.78 screen (all lights on). Tough to find a projector to handle those parameters.............3 chip is the only way for me.
Another fact you might consider with screen and projector selection is contrast, ie. bright/dark scenes..........the LS-5 has great blacks for DLP! Once again...........visit store fronts and find out for yourself ie. don't listen to anybody, including me!
