Is This Right For You?
Installing a permanent setup and prioritizing image quality. The laser light source and short throw capability deliver exceptional brightness and clarity in a dedicated space.
Great fitOperating in a room that can't be fully darkened. The laser projector's exceptional brightness (4000+ lumens) handles ambient light far better than standard projectors.
Great fitLooking for the lowest entry price into sim golf. Premium laser technology comes at a premium cost. The BenQ MW560 at $499 or the TH575 at $749 are lamp projectors that still run a simulator well.
Worth knowingWanting portability to move between rooms or store away. The short throw projector design and laser mechanics are optimized for fixed installations. For a setup you move or store between sessions, look at the BenQ GV50 or GV32 portable projectors.
Worth knowingRoom Size Guide
Tip: The BenQ LH820ST's short-throw design projects a full 3m screen from just 1.5m away. Mount above and behind the hitting position for optimal ball flight tracking and unobstructed swing space.

HOW IT STACKS UP
BenQ LH820ST+ vs Optoma GT2000HDR
Both short-throw lasers for a sim bay. The BenQ is brighter and quieter; the Optoma is cheaper with higher rated contrast.
Brighter, quieter and rated for 30,000 hours — the LH820ST+ is the one for a room you cannot fully darken.
