BenQ WBA for Seamless Multi-Projector White Calibration BenQ’s factory white balance adjustment (WBA) reduce variables between images projected from different projectors, significantly reducing manual calibration effort. It can save up to a full day of setup time in large-scale installations while ensuring seamless multi-projector alignment for edge blending. IP6X Sealed Engine Design for Dust-Prone Environments Shields the projector’s optical engine from dust intrusion, ensuring long-term stability and reliable performance in harsh, dust-prone environments such as exhibition halls, factory spaces, and training centers. Optional Filter for Extra Protection Provides added protection in dusty environments and helps extend projector life. Auto Reset Mechanism with Built-in Timer Automatically tracks filter usage and resets the timer when a new filter is installed, without any manual setup.
