Frequently asked questions
Will the BenQ LH820ST fit in my room?
Paired with a SIG10 Golf Simulator Enclosure, the BenQ LH820ST needs at least 9' of ceiling height and 6'5" of room depth when the rest of the room is roomy. It fits 4 of 6 common simulator rooms we tested (3 of them tight). Open it in the BirdieBuild 3D planner with your exact room size, ceiling obstacles and golfer height to see a live verdict.
What ceiling height do I need for the BenQ LH820ST?
At least 9' for a 5'10" golfer. 10'6" or more clears it without any marginal warnings. For full driver swings, BirdieBuild's rulebook recommends 10' of effective ceiling regardless of equipment.
How far from the screen should the BenQ LH820ST be mounted?
For a 10'1"-wide image, mount the lens about 5' from the screen. Check that position against your swing — a projector too close to the hitting area is a club-strike risk.
How much does the BenQ LH820ST cost?
About $1,899. Prices are from our last catalog review and change often.
