The Da-Lite 24523 110 x 176" UTB Contour Fixed Frame Screen has an ultra-thin bezel and acid etched black aluminum frame for keeping the audience's focus on projected content. The HD Progressive 0.9 surface has a 0.9 gain and 170° viewing angle, with black backing to prevent bleed-through and retain brightness. Its low-profile flat-panel design allows it to sit 1.38" off the wall. The front lip of the bezel is .25" wide all around the viewing surface, which sits .13" off of the inner frame component.
