• The dimensions are based on the BenQ wall mount (P/N: 5J.J4R10.001).
• 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 projector's optical characteristics. This will help you determine the
exact mounting position so that it best suits your installation location.
• The dimensions supplied are offered as a guide only and may differ depending on several factors
relating to any specific installation.
• The dimensions are based on the projector being configured with zero keystone correction.
• The dimensions assume that the wall mount arm is positioned 90° from the bottom case of
projector and screen surface.
