I was really worried about getting a PJ, as it would be my MAIN tv and obviously a theater.
What would it look like in ambient light?
Of course it is washed out, but not nearly as bad as I expected.
I don't know a thing about projectors, will I be able to figure it out?
All I had to do was throw a mount on the rear wall and i was good to go!
Do I really NEED that big of a screen?
Heck Yes, My PJ setup never fails to get compliments
What will it look like for non-hd images?
Of course you can see some of the pixels, but it doesn't bother me anymore than the artifacts on my RPTV. (Note: My PJ throws a 106' image, which is the max it can display at the distance i have it set at it, so if i zoom in there would be less)
I also live in an apartment and I am really happy I replaced my 55' Sony RPTV(Rear Projection, Typical 'new' big screen) with a Sanyo Z5. So I encourage you wholeheartedly to get a PJ
Hope this helped, once the bug bites, your hooked
