However, the benefit of a gray screen is not just deeper blacks, but also increased contrast, as well as being able to resist reflected light from the environment. Gray screens are less affected by reflected light than white screens, making them ideal for home theater and living room theaters.
With the development of science and technology, there are ultra short throw screens on the market now, and this kind of anti-light projection screen will see different colors at different angles, but it is very good anti-light effect, matched with ultra-short-throw projector, it can present a clear projection effect even in the room with the lights on.
