Which one: 2.35 or 1.78?

[ImPulSive]

I am trying to decide if I should go with a 2.35 screen or a 1.78 (16x9). I am holding off on buying anything yet until the new series of PJs are released to see if there will be any sales or significant upgrades to consider. Right now I am 99% set on the Panny AE4000, but I am still confused by which screen to get. I would love to have the money to spend on a Black Diamond screen but I can not justify the cost, especially since the room will be dedicated and I should not have any ambient lighting issues. Leaning towards a Carada screen.

My biggest question has been whether to get a 2.35 or a 1.78 screen. If I got the 2.35 screen then I could use the zoom feature of the AE4000 to resize for other AR like 1.78 but the width of my picture would be shrinking too. If I got a 1.78 screen then I could maintain a constant width and maximize the big screen affect for all content. But there must be one or more reasons why people chose 2.35 CIH screens over 1.78.

So my question is, why get a 2.35 screen when I could get a 1.78 screen?

1. Is it a masking issue with black bars on the top and bottom for content with an AR greater 1.78 and these bars are noticeable and distracting on a 1.78 screen?
2. Or is it just cost since the same width screen will have more material for a 1.78 AR?
3. What am I missing and will I be happy with 2.35 content on a 1.78 screen?

I am looking at a total screen width (frame included) of 130 inches max. Thanks.
