I am about to finally mount a Benq W1070+ projector with ceiling mount to watch it on a 100" EliteScreens Saker screen.
Though, I am not sure if I understand the vertical offset data in the manual (attached picture).
It says, for a 100" screen, the min distance should be at least 2532mm, the average should be 2911mm, the max should be at 3291mm, while the vertical offset is 62mm.
What does the 62mm vertical offset mean? I understand I need to take the 1245mm height of the screen and add this 62mm to its top to get it, but what information does it give for mounting?
1. If the top of the screen is 80mm away from the ceiling, then should the projector be installed with the lens exactly at 18mm, or more than 18mm from the ceiling?
2. As the 62mm is exact distance, not percentage as in instructions of other brands, is it given for the average (2911mm) screen distance?
3. Using a popular calculator on the net (http://www.projectorcentral.com/BenQ...calculator.htm
), I created some screenshots for the above mentioned distances (min, avg, max). Why are the scales in the red zone? What does it mean?
Thanks for any help!
