How to install BenQ LS2ST1

• Power off the projector and unplug from the power source to prevent any electrical shock or damage during installation.
• Detach the current lens (if applicable) following the projector’s lens-release procedure. This usually involves a release button or screw mechanism on the lens mount. Keep any mounting hardware in a safe place for reuse with the LS2ST1.
• Align the LS2ST1 with the projector’s lens mount. Ensure the alignment pins or notches match up with the corresponding receptacles on the projector to avoid cross-threading or misalignment.
• Insert the LS2ST1 into the mount and rotate or secure it as required by the projector model. Ensure the lens is seated firmly and lock it in place with any mounting screws or locking ring specified by the manufacturer.
• Power on the projector and allow it to boot. Use the projector’s manual focus and zoom controls to bring the image into focus and adjust the frame to the desired boundaries. If the projector provides lens shift or keystone controls, fine-tune these to achieve a rectangular, distortion-free image.
• Check color accuracy and brightness across the screen. If necessary, adjust gamma, contrast, brightness, and color balance through the projector’s image settings to optimize image quality with the LS2ST1 installed.
• Test a variety of content at different throw distances to confirm consistent sharpness and brightness. Recheck mounting security after extended use and periodically verify lens alignment as part of routine maintenance.
