Real-World Pro-Tips for the C2 at Massive SizesWatch the Distance: If you actually want to hit the maximum 300-inch layout from behind the screen, you will need a massive space. Because of its throw ratio, the projector needs to sit 20 to 32.5 feet behind the screen to hit that 300" limit.Mind the Brightness Drop: While the C2 Ultra outputs an incredibly bright 3,000 ANSI lumens, pushing any projector to a 300-inch screen dilutes the light intensity heavily. For a punchy, cinema-quality rear projection setup, keeping the screen size between 120 to 180 inches will give you a much more vivid image.Use the Right Material: A standard wall or white projector screen will block the light. For rear projection, you must use a dedicated, semi-translucent rear projection fabric or mesh screen.
