One of the most important feature of the projector screen is contrast. The most effective and most flexible type of screen to use for theater environments and multi-purpose projection would be a high-contrast screen. What a high-contrast screen does is to make the darker colors easier to see because it lowers the light levels coming from the projector. Because of this, the viewer can also experience sharper color separation. Some of the more common problems like blurring and pixelation are eliminated. Screens that are low-contrast can be used for still images where the transition of images is not fast or sudden, but remains in view for a long time. Usually, images projected this way can be viewed by a wider audience. It is good to note that this type of projector screens can sharply reflect images on static display without encountering contrast distortions. If you have a whiteboard, it can also function as a projector screen. Whiteboards are now commonly used in presentations. There are many whiteboards on the market that have the ability to interact with a computer with the user issuing commands through the whiteboard itself.
