BenQ LK935:

The BenQ LK935 elevates premium golf simulator studios with true 4K UHD (3840×2160) clarity, 5500 ANSI lumens of punchy brightness, and BenQ’s Golf Picture Mode for lifelike fairways, greens, and skies. A 1.36–2.18 normal-throw lens with large H/V lens shift (±60% / ±23%) and 1.6× zoom makes ceiling-mounting behind the golfer simple—even in challenging rooms.

A BlueCore laser light source rated for 20,000 hours and IP5X DustGuard optical sealing deliver low-maintenance reliability. With 3D Keystone, 360° rotation, HDBaseT, dual HDMI 2.0b with HDCP 2.2, DisplayPort, and ARC/S/PDIF audio, the LK935 is a flexible, install-friendly 4K workhorse for serious sim players.

FAQ

Q: Can the LK935 be ceiling-mounted behind the golfer?
A: Yes. Its normal-throw 1.36–2.18 lens and large lens shift are designed for behind-golfer installs.

Q: Is 4K really helpful for golf sims?
A: Absolutely—4K UHD preserves fine course textures, pin flags, and ball edges for a more realistic image.

Q: Do I need to clean filters?
A: No. The IP5X DustGuard optical engine is filter-free and designed for low maintenance.

Q: Will it work with long cable runs to the projector?
A: Yes—use HDBaseT for reliable video/audio/control over long distances.

Q: What about latency for golf software?
A: Latency is about 33 ms at 1080p/60, suitable for simulator play.

Installation

Install Tips

• Target the middle of the throw range for easier focusing and more uniform brightness (example: 12 ft wide screen → ~21 ft throw).

• Use the ±60% vertical / ±23% horizontal lens shift for fine adjustments; keep keystone as a last resort.

• If using 21:9 aspect ratio, throw distances will be based on screen width in the same way (wider image, same formula).

• For long HDMI runs, use HDBaseT or an active/fiber HDMI cable to maintain 4K HDR signal quality.
