Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format 
each factors in the projected image size.
The native resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 aspect ratio 
(expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect ratio image, the 
projector can resize and scale a widescreen image to the projectors native aspect width. This 
will result in a...

How to determine the position of the projector for a given 
screen size
1. Select your screen size.
2. Refer to the table and find the closest match to your screen size in the left columns 
labelled 4:3 Screen Diagonal. Using this value, look across this row to the right to find 
the corresponding average distance from screen value in the column labelled Average. 
This is the projection distance.
3. On that same row, look across to the right column and make note of the...

There is 3% tolerance among these numbers due to optical component variations. BenQ 
recommends that if you intend to permanently install the projector, you should physically test 
the projection size and distance using the actual projector in situ before you permanently 
install it, so as to make allowance for this projectors optical characteristics. This will help you 
determine the exact mounting position so that it best suits your installation location.
