While you might consider using a plain white wall to save the expense of a projector screen, projector screens provide several benefits to the cheaper counterpart. You might get an adequate image with use of a white wall, but a custom built screen has optical coatings that enhance the image by displaying highlights brilliantly, intensifying contrast and colour saturation, and increasing sharpness. Furthermore, the screen acts as a frame and is a critical element in the overall visual experience. A solid black frame around an image considerably boosts the quality of the image itself and often, this feature is over-looked. I have experience in techniques which maximize a quality image size and align the screen proportionately. My custom built screens maximize the viewing area in your media room and provide you with the perfect backdrop for your favourite films and videos.
