What is the suggested limit value of keystone adjustment when the projector is connected to PointWrite-PW02?
If you overly calibrate the distorted image, it may impact the interactive performance. In order to ensure the optimal writing accuracy, please limit the keystone range within ±2 steps.
Which type of color wheel sensor is projector equipped with?
It is equipped with convex color wheel sensor, which can prolong optimal performance of color wheel.
(1) Convex curvature is better for IR signal emitting and receiving.
(2) Convex curvature rejects dust which can accumulate on concave sensors to block the IR signal.

Which types of BenQ projectors require a power cycling process?
For BenQ projectors designed for general home entertainment and business use, we recommend powering off the projector for 2-3 minutes after every 12 hours of constant use for longer lasting reliability and maximized projector lifespan.
BenQ professional projectors designed with corresponding industrial standards can be used continuously for more than 12 hours and do not require a power cycling process as our home and general-use business projectors do.
If you have any questions, please contact your local BenQ customer care team for further assistance. Thank you.
