FAQ

Q: Is the LK830ST good for golf simulators?
A: Yes. The 0.5 ultra short throw ratio projects a large image from a short distance, ideal for simulator enclosures. Combined with true 4K UHD and 4000 lumens, it delivers sharp course detail and bright visuals even with ambient light.

Q: How large of a screen can it display?
A: Up to 300" depending on room layout and mounting distance. The ultra short throw design maximizes screen size in limited-depth spaces.

Q: Can it be ceiling mounted?
A: Yes. 360° installation supports ceiling, wall, floor, and portrait orientations. An optional universal ceiling mount (CM00G3) is available.

Q: Does it perform well with lights on?
A: With 4000 ANSI lumens, it performs well in moderate ambient light — suitable for commercial simulator bays, training facilities, and multi-use rooms.

Q: How long does the laser light source last?
A: Up to 20,000 hours — years of operation without lamp replacements.

Q: Is it suitable for high-dust environments?
A: Yes. The IP6X sealed optical engine prevents dust intrusion. An optional air filter provides added protection for demanding environments.

Q: Why does flickering appear in videos recorded of the projector?
A: All DLP projectors use color-sequential display technology. If a camera’s shooting frequency exceeds the projector’s color-switching frequency, flickering may appear in recordings. This does not affect normal viewing.

Q: How do I activate network control functions such as PJLink?
A: Connect the projector and computer to the same network, enter the projector’s IP address into a browser, and create administrator credentials through the web interface before first use.
