Thanks so much for this thread, MM. It's because of your threads that I've decided to simplify my home theatre and get it to a usable state more quickly. I'd previously had a recess (fully wired up with ethernet, HDMI USB etc.) built into the wall for a 60" TV and was going to get a 120" retractable screen to drop in front of it. However, I've decided to wait until both TVs and tab tensioned screens drop in price. Therefore I'm going with a temporary solution for now.
Thus, we've now covered the recess with a horizontally hung (screwed in) piece of drywall with 120" diagonal of 16:9 proportions. This will be painted exterior grey (or silverfire if I can get all the stuff) for my Epson 8350. I want to make a velvet trim for this, but heres the problem; there's only 1.5" or so between the edge of my drywall screen and the frames of the in-wall speakers to be (currently only the holes have been cut out and the wiring done).
Is it worth doing a 1.5" trim and what's the best way to do so, if so? Just use 1.5" mdf molding?
Thanks for any help you can offer. We were going to cover 2" of the drywall edges in velvet, but I just realised that not only may this create a slight shadow, but it'll also result in the visible area of the screen no longer being exactly 16:9; this could be a big deal for HTPC use, where you don't want much overscan at all.
