If you’re setting up a home theater room there are a number of things to consider. For example, the optimal distance from the screen for viewing a video image is dependent on the resolution of the video image. Also, different people have different preferences for how far the video image extends into their peripheral vision – where people like to sit in a commercial movie theater is a good indication of their preference. CTA/CEDIA-CEB23-B describes how to determine a recommended screen size based on the primary seating position. It also discusses how to mask portions of the screen when the shape of the video image doesn’t perfectly match the shape of the screen. It covers recommended room lighting, and coloring for walls, ceilings and carpets, as well as a number of other factors that should be considered when setting up a home theater.
