A short-throw projector is the one piece of gear most first-time builders underestimate — plug in a regular projector and you'll spend your first session casting a shadow across your own screen mid-swing. A proper short-throw unit sits close to the impact screen and throws a big, sharp image without needing the long distance a normal projector wants, which is exactly what a garage or basement room doesn't have. Here's what actually matters when you buy one.
Get a true short-throw (or ultra-short-throw) 1080p projector rated for at least 3,000 lumens, mounted above and just behind the hitting area so your body never crosses the beam. Resolution matters less than brightness and correct placement — a dim or badly positioned projector ruins the experience faster than a lower-resolution one ever will.
BenQ LK936ST
A genuinely bright, sharp laser projector built for short-throw placement, which makes it a strong match for a garage or basement sim where you need a big image from a short distance. Handles both course play and data screens clearly.
Check today's price →Why short-throw specifically
Regular projectors are designed to sit several feet back from the screen, which in a home sim room means mounting it directly in your swing path or behind where you're standing — neither works. A short-throw model can sit close to the screen, usually mounted on the ceiling just behind and above the hitting area, throwing a large image from a short distance without your body ever crossing the beam mid-swing. It's not optional gear for a sim room; it's the specific spec that makes the room function.
What actually matters when buying one
- Brightness (lumens) — aim for 3,000+ lumens if your room has any ambient light; a dim image is the single biggest complaint from new builders. See our broader projector guide for a full breakdown.
- Throw ratio — the lower the number, the closer it can sit to the screen and still fill it. True short-throw units are what you want here, not just "compact" projectors.
- Resolution — 1080p is genuinely enough for most home sims; 4K looks nicer but costs meaningfully more for a marginal gain on a screen you're hitting balls at, not sitting close to.
- Input lag — lower is better for a responsive feel when the ball flies, though it matters far less here than it would for competitive gaming.
- Mounting flexibility — check keystone correction and lens shift range so you can get a square image even if your ceiling mount isn't perfectly centered.
Screen distance and image size
Before ordering, measure the actual distance you'll have between the projector's planned mounting point and the impact screen, then check that number against the specific model's throw-distance chart rather than trusting a general "short-throw" label. Two projectors marketed the same way can need meaningfully different distances to fill an equivalent screen size, and getting this wrong means either a smaller image than you wanted or a unit that can't reach the edges of the screen at all. If your room is unusually short front-to-back, lean toward the shortest throw ratio you can find rather than the brightest spec sheet.
Placement: where it actually goes
Mount the projector on the ceiling, above and slightly behind the hitting area, angled down at the impact screen. This keeps it clear of your swing path and your body while you're set up over the ball. Check your specific projector's throw distance chart against your room dimensions before buying — a unit that's a perfect short-throw for a 10-foot screen distance can be wrong for a smaller or larger room.
Short-throw vs. a regular projector: what you're really trading
It's tempting to save money by using a projector you already own, but the math rarely works out. A standard-throw projector needs several feet of distance to fill the same screen a short-throw unit covers from close range — distance most garages and basements simply don't have between the hitting area and the back wall. Force it, and you'll either mount the projector where your backswing can clip it, cast your own shadow across the image at the worst possible moment, or end up with an image too small to feel immersive. The short-throw premium isn't a luxury upgrade here; it's what makes a ceiling-mounted, out-of-the-way install possible in a normal-sized room at all.

Spec my build →Frequently asked questions
Do I really need a short-throw projector for a golf simulator?
Yes, in almost every home setup. A regular projector needs distance you don't have without mounting it in your swing path or standing area — a short-throw unit solves that by sitting close to the screen.
What's the difference between short-throw and ultra-short-throw?
Ultra-short-throw projectors can sit just inches from the screen, while short-throw units need a few feet. Both work for a sim room; ultra-short-throw gives you more flexibility in very tight spaces.
How bright a projector do I need for a golf simulator?
Aim for at least 3,000 lumens, more if your room has windows or overhead lighting you can't fully block. A dim image is one of the most common complaints from new builders.
Where should I mount a short-throw projector?
On the ceiling, above and slightly behind the hitting area, angled down at the impact screen. Check the exact throw distance chart for your model against your room's dimensions first.
Is 4K worth it for a golf simulator projector?
Not usually. 1080p is sharp enough for most home sims, and the extra cost of 4K is better spent on brightness or a better impact screen.
