How a black screen works is that it does not reflect any of the ambient light, but only the light falling on the screen from the projector in the perpendicular direction. This means that you can use a projector in a well lit room and there is no need to darken the room..
Accordingly, is a black projector screen better?
The most significant difference is probably obvious: a black screen is a lot better at reproducing the darker portions of the image. This visibly improves the contrast of the image. Black screens also don't reflect as much light as white screens and perform better in rooms with ambient lighting.
Beside above, how does a projector screen work? In an LCD TV projector, a very bright light shines through a small LCD screen into a lens, which throws a hugely magnified image of the screen onto the wall. The technology is sometimes called LCLV (liquid crystal light valve).
Similarly, how does a projector display black?
Projectors do not project the color black. When a projector sends a beam of light on to a wall or a projector screen so that an image is formed on the wall or screen, the parts of the image that look black are really a very dim white color (which we sometimes call gray).
What is the best color wall for projector?
Go gray. Depending on how many lumens your projector produces, you may want to grab a paint that's closer to gray than white. A general rule of thumb is that you should go gray if your projector's specs say it produces more than 3,500 lumens.
