I'll grab some pics of the mounting system tomorrow, as I actually need to remount it. Grrr. I'll go ahead and scan the manual as well if anyone wants to see it.
So the screen attaches to two metal mounting strips in four places-- two up top and two on the bottom. They're not the best pieces of metal in the world, but I suppose they'll work (I haven't heard a crash downstairs yet). There are pilot holes in various places on both strips for securing the strips to concrete or studs. The only problem is that the pilot holes don't extend the full length of the strips, so the outer 6 inches or so aren't physically bolted to the wall. The result is that one of the corners of my frame isn't flush with the center, and so the picture doesn't align perfectly in that corner. Each strip has a lip for hanging the screen's hooks, and the bottom piece has a ledge to further support the screen's weight. Truth be told, I think the mounting system is subpar. I don't think it's going to crash down off the wall on its own, but the armchair engineer in me would have made it wider and with more pilot holes.
I'm shocked just how large this fully assembled screen is. The frame is 10cm thick, which seriously adds some bulk to my screen wall. But I'm definitely not complaining there, as it looks great. I can't imagine attempting to mount the 120" version with fewer than three people. I swear this thing feels like it put on another two hundred pounds between building this afternoon and mounting this evening.
Still haven't thrown a real picture at it yet, other than a convergence grid for geometry adjustments. I will say that I didn't have to muck around with my brightness/contrast to compensate for the .8 gain in checking out the grid, so yay I guess.
Edit: So it's approaching midnight and I've watched some HD boxing on Showtime and half of Zombieland on Starz-HD and I'm really, REALLY liking the screen now. There are no hotspots or problems with uniformity. I think the gain rating might even be underrated, as it's nice and bright. My HCCV Perm-Wall rated in at 1.1 and I can't tell a difference. I'm VERY impressed (and relieved) so far.
