The only three projectors worth buying for a golf simulator

The projector is the part of a home simulator people overthink the most, chasing 4K numbers and contrast ratios that vanish the moment the room isn't a blacked-out cave. Here's the honest shortcut: for a golf sim, only two things really decide it — how much light your room fights, and how much you'll spend — and the answer lands on one of three projectors. Everything else is detail.

First, the one spec that isn't optional: short throw. In a sim you stand between the projector and the screen, so a normal projector throws your own shadow across the ball. A short-throw unit (roughly a 0.5 throw ratio) mounts on the ceiling near the screen and fills it from a few feet away, keeping the light over your head instead of behind it. Every pick here is short-throw; if a projector isn't, it's wrong for a sim no matter how good the image.

If you can dim the room: BenQ TK700STi

For most builds this is the answer and the search can stop here. The BenQ TK700STi gives you true 4K, genuinely low input lag so the ball flight feels connected to your swing, and a short throw made for ceiling mounting — for around a grand. Its one limit is brightness: at 3,000 lumens it wants the lights down or a room without big uncovered windows. If your sim lives in a garage, basement or a room you can dim, that limit never bites and you've spent your money exactly right.

If the room has real ambient light: Optoma GT2100HDR

Brightness, not resolution, is what actually breaks most sim pictures — a sharp 4K image looks washed-out and grey the second daylight hits the screen. If your room has windows you can't fully cover or lights that stay on, the Optoma GT2100HDR is the fix: a 4,200-lumen laser that punches through ambient light and holds a watchable, contrasty image where the TK700STi fades. It's natively 1080p rather than true 4K, which sounds like a downgrade and isn't — on an impact screen at swing distance, a brighter 1080p image beats a dim 4K one every time. The laser also means no lamp to replace.

If it's a dream room and the picture is the point: BenQ AK700ST

When the sim is a dedicated, designed room rather than a corner of the garage, the BenQ AK700ST is the projector built for exactly that. It's the rare unit tuned for golf first — true 4K, a bright 4,000-lumen laser, golf-specific picture modes, and fast corner-fit keystone that makes the install less of a wrestle. It's a premium spend at around three grand and it's sold through golf specialists rather than Amazon, so it's overkill for a starter bay — but in a room where the image is part of the experience, nothing else here matches it.

The mistakes that waste the money

Three, in order of how often they bite. Chasing 4K over lumens: in a room with any ambient light, brightness wins, so buy the laser before the extra resolution. Ignoring input lag: a projector with sluggish response makes the ball leave the screen a beat after you swing, and once you feel it you can't unfeel it — all three picks here keep lag low. And forgetting the screen: a projector is only as good as the surface it hits, so pair it with a proper impact screen inside an enclosure, not a bedsheet — the standoff and the screen material do half the work of the image you see.

The honest decision

Dim room, sensible budget: the TK700STi, and don't look back. Bright room: the Optoma laser, and enjoy not fighting your curtains. Dedicated dream room: the AK700ST. That's the whole decision — match it to your light and your budget, not to the longest spec sheet. If you're not sure which tier your whole build should sit in, our Sim Room Architect fits the projector to your room and budget alongside every other component, and the complete home simulator setup shows where the projector sits in the wider build.
