It's a 1.78:1 Luxus ScreenWall with a 110" diagonal. It's the Ve-Lux frame.
I just found four L-shaped brackets in the bubble wrap that I didn't know were there. I almost threw them away. I suppose they will do the trick.
I didn't want to use molding at all, but I doubt that the dimensions of the aperture will be dead-on. I guess some flat black trim will be ok. Any other suggestions?
Thanks!
