Our projector calculator estimates the brightness of the screen in fL (foot-Lamberts). For example, the Stewart FireHawk screen provides a maximum gain in brightness of 1.1, and the Da-lite High Power Screen of as much as 2.8. Screen gain: if you use a special material for your screen, it can increase or decrease the brightness of the projected image.It is expressed in ANSI lumens and describes how bright is the image projected by the device. Projector brightness: you can find it in the manufacturer's specifications of your projector model.First, you need to input the following values: The next step in setting up a perfect home cinema is choosing the proper projector to ensure correct brightness levels. Maximum viewing distance recommended by SMPTE: similarly, the SMPTE (Society of Motion Picture and Television Engineers) recommends a maximum viewing distance that should ensure optimal quality of watching movies in a home theater.They suggest that sitting at this (or closer) distance to the screen will result in optimal viewing conditions. Maximum viewing distance recommended by THX: apart from setting a maximum allowable viewing distance, THX also specifies the maximum recommended distance.You can also open the advanced mode to get more information on recommended viewing distances: Hence, if sitting at the optimal distance would mean you sit too close to the screen to get the whole picture in your field of view, you can decrease the image quality without any consequences for viewing quality. The higher the resolution, the closer to the screen you should sit. Optimal viewing distance (quality-wise): regardless of the field of view, this value specifies the distance between the audience and the screen that ensures you see all available detail.For the movie theater to obtain the THX certification, the audience must sit at this distance or closer to the screen. ![]()
