At what angle should a screen and projector be set in relation to uncurtained windows?

The optimal angle for a screen and projector in relation to uncurtained windows is 180 degrees. This arrangement ensures that the projector is directed towards the screen, with the light and images projected in a straight line. By positioning the projector at a 180-degree angle in relation to any potential glare from the uncurtained windows, it minimizes the chances of light interference and enhances visibility on the screen. This is especially important in maintaining clarity and brightness of the projected image, as any other angle could introduce light scatter that diminishes the viewing experience.

In a classroom or presentation setting, ensuring that the projector and screen face away from windows helps in avoiding the natural light that can wash out the projected content, making it difficult for viewers to see the material being presented. This is why placing them at 180 degrees is key to achieving the best viewing conditions.
