When projecting images onto a completely flat screen, the distance light has to travel from its point of origin (i.e., the projector) increases the farther away the destination point is from the screen's center. This variance in the distance traveled results in a distortion phenomenon known as the

The optimal position of viewing a screen is directly along the central axis of the TV with the central point of the screen at eye level. Other viewing positions or angles may cause degradations in picture quality ranging anywhere from minor to severe, the most notable being trapezoidal distortion.

monitors were developed in order to display the maximum amount of information on a single screen. However, the extreme wideness of the screen created severe distortions on the left and right edges of the screen. Curved 21:9 monitors were then developed to address this issue and provide a
