Efficiency Installation with BenQ Wall Mount Alignment System

Designed to help ensure a fail-proof projector installation, BenQ has implemented extra help into its wall mount design. This installer-friendly ultra short-throw projector wall mount features an installation chart and a measuring ruler to help you find the most suitable projector-screen alignment and image position for your classroom.
