# Problems with image contrast.

Check the surface of the screen. If dirt and impurities are accumulated, those could reduce the reflectiveness of the projector screen. You can have a wet cloth and a mild soap to wipe down the dirt. Make sure not to wipe aggressively. Immediately clean any dirt so it won't stain the projector screen.
