The material I bought for the “roof” (black out type material to keep light in for the projection) I decided to hang from the top of the viewing slot, along the sight line string, to the top corners of the video wall. It means that when you look in, you can see the entire breadth of the video wall without cropping too much out. As for controlling the sight line for the top and gotten, I used bent black card. Although this crops out a line of videos at the top and the bottom, it works perfectly or controlling my audience’s sight line. Now I need to buy more material for the top to keep the light in.
