      White Balance Calibration for Seamless Edge Blending

      BenQ LH820ST with exclusive white balance adjustments reduce white balance variables between images projected from different projectors to Delta E<2 that the most people cannot see any difference. This allows for seamless and accurate picture quality without disruptive discrepancies, saving the installation staff from repetitious fine-tuning.

      Short-Throw Design Shatters Space Constraints

      The LH820ST short-throw laser projector is best for indoor interactive entertainment, simulation training, and commercial space exhibitions. It’s easy to project images larger than 100” within 1.07m and short-distance projection prevents people or objects from getting in the way and casting a shadow on the projected image for the most immersive viewing experience possible.
