The Draper 40.25 x 53-5/8" Vortex Rear Projection Screen with Frame 200 - 67" Diagonal - Video Format (4:3 Aspect Ratio) (Black/Clear Anodized). A 0.5mm Fresnel lens gathers the light from the projector and directs it at a right angle through the screen. As the light exits the screen on the audience side, a diffusion medium redistributes the light evenly in all directions - up, down, left, right and center.
The superior resolution of this screen is complimented by its high-quality color contrast. The viewing cone is exceptionally wide in both axes - horizontal and vertical. The screen also provides uniform brightness from edge to edge, with no hot spots.
