•  The dimensions are based on the BenQ wall mount (P/N: 5J.J4R10.001).
•  All measurements are approximate and may vary from the actual sizes. 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.
•  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.
