The truth appears to be this: when ceiling mounting, the top of the projected image isĪlways below the lens. The closer you can get it to the optimal position of 6" from the center of the lens above You can do the same thing for any 16:9 screen size (95" screen is * 0.95). The OPTIMAL / no lens shift position (using none) = 5" * 1.2 = 6" above The maximum for 120" screen is 7.5" * 1.2 = 9" above the screen So the minimum for 120" screen is 2.5" * 1.2 = 3" above the screen Whatever your screen size is, simply multiple it by the diagonal offset. I prefer speaking in diagonal offsets because it makes it simpler, let me show you. How much lens shift it has is based on the VSHIFT UP and VSHIFT DOWN in my calc. MyĬalculator in that field is telling you the default diagonal offset, not how much lens shift The W1070 needs to be 3.3" above the top of my screen (height of screen 66" X 5% = 3.3").Ģ.5" to 7.5" per 100 inch diagonal screen (with 5" being the default no shift position). To the ideal brightness of about 16 fl, based on the calculator at set the distance from the projector to the screen to 14 feet, 4 inches to get close made sure screen was level, in all directions: top, sides, and front to back My eye level is just above 1/3 of the way up Although anywhere from 1/3 to 1/2 way up the Is generally considered a good screen height. having your eyes level with approximately 1/3rd of the way up from the bottom of your screen from eye level to the top of your screen should not exceed 15 degrees (THX). Went with about a 34ĭegree angle for my primary seating position.
