I remember when I bought my first projector about six years ago. It was a Sanyo Z2, which was a 2003 model so I felt I was getting a good deal on it. The day it arrived, I had already created my DIY screen goo screen, which was around 115". I took it out of the box, connected everything, and then fired it up. I'll never forget how I felt when I saw that the image was literally taking up the entire wall in size, much MUCH larger than the dimensions of the screen I had created. On the one hand I was not happy that I hadn't been more careful learning about throw distance and all that, but on the other hand seeing an image that size blew my mind! The movie 50 first Dates was on, and to have Drew Barrymore and Adam Sandler life size in my room was pretty cool.
Anyway, since that time I've had a few variations of screen type and size, over the course of living with two projectors (I upgraded to a Mitsu 4900 in 2007). I've definitely observed the improvements in PQ from a screen that is slightly smaller in size, but I think when it all comes down to it, I'd rather have a screen that is maxed out in size vs having the absolute best PQ.
I have always found videophiles amazing. On the one hand I understand them, because I am just as detail oriented and picky about audio. I'm an audiophile. On the other hand, they tend to focus on things that, quite often, I just don't seem to observe as easily as they do. I remember when I posted some screenshots from my 4900 when I first got it. To me,they looked great! But I'll never forget how at least half the comments seemed to pick up on deficiencies that I just didn't see at all.
So what I'm curious about is how many of you guys would rather have a bigger screen, even if at the expense of image quality just a bit? I'm not talking about putting up a 200" screen and having a completely washed out image...I'm talking about maybe going 20" more than what you probably should in terms of size, just because the idea of a larger screen appeals to you more than preserving every last bit of PQ?
