I'm seriously thinking of going from my current 88" framed canvas screen (1.85:1) to a painted screen. My wish is for the new projected area to have about the same height as my current screen but to expand the width to get a 2.35 or 2.4:1 ratio.

What I'm primarily wondering is how to best devise a framing system that will allow me to adjust the side borders, so that when I'm watching a HDTV signal at 1.78:1, or a movie at 1.85:1, I won't have white screen on the sides. I know that my projector (Panasonic AE900) will output black letterboxing, but it's not the same as a black felt frame.

I was thinking of an affixed 2.4:1 felted frame of some sort on which I could attach and remove a solid structure of some sort as needed. My wife was imagining some sort of adjustable curtain like at a movie theater.

Anybody done this or have ideas? Thanks!
