This remote control is a direct substitute for the BenQ 1051D-2566 projector remote. It provides full compatibility with BenQ projectors that use this model number, allowing you to control power, input selection, brightness, contrast, and other essential projector functions from a distance. The remote features a standard layout with clearly labeled buttons for intuitive operation. It operates via infrared transmission, requiring a direct line of sight to the projector's receiver. The ergonomic design fits comfortably in your hand for extended use. Compatible with BenQ projector models that accept the 1051D-2566 remote specification. Verify your projector model before purchase to ensure compatibility.
