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.
