BenQ AK700ST

---

You’ve built the enclosure. You’ve mounted the screen. You’ve got the launch monitor sitting pretty, the mat down, the software loaded. There’s one thing left, and everyone who’s done this before knows it’s the worst part of the build.

Mounting the projector.

Not picking it. Mounting it. The ladder. The “move it an inch, climb down, check, climb back up, move it another inch, climb down, check” dance. The keystone correction menus that never quite fix the trapezoid. The moment you realize the image is six inches too high and your mount is already bolted into the ceiling joists.

BenQ fixed that. The AK700ST has a button on the remote called Auto Screen Fit. You press it, the projector uses its built-in camera to find the edges of your screen, and it aligns the image perfectly. In ten seconds. No ladder. No keystone menu. No swearing.

That’s the headline. Let me tell you the rest.

What Actually Makes This Projector Different

BenQ has been making projectors for golf simulators for years. The AH700ST was the workhorse — 1080p, 4,000 lumens, reliable, affordable. Still a great projector. But it was a golf projector the way a steak knife is a steak knife — it worked, you just had to do the cutting yourself.

The AK700ST is the first projector built for the guy who doesn’t want to install a projector. He wants to use one.

The feature list, without the marketing speak:

Auto Screen Fit — Camera detects your screen edges. Press a button. Done. Supports 16:9, 16:10, 4:3, and 1:1 aspect ratios. If you mount it off-center or at an angle, it corrects for that too.

4K UHD — True 3840x2160 resolution. Not “4K compatible” or “upscaled to 4K.” Real pixels. Eight million of them. Every blade of grass on Augusta shows up.

4,000 ANSI lumens — Bright enough for a garage with the door open. Bright enough for a basement with the lights on. You won’t be squinting.

Short throw (0.69-0.83) — Project a 120-inch image from about 8-10 feet away. The projector sits behind you, out of the swing path. No shadows.

Golf Mode — BenQ worked with course designers to calibrate the color profile for green grass, blue sky, and sand that looks like sand. It’s a preset. You turn it on and forget it.

Curved screen warping — If you’ve got a curved impact screen (and more people are building them), the AK700ST is the only BenQ model that supports image warping for non-flat surfaces. Four matrix options from 5x3 up to 24x15.

IP5X dustproof laser — 20,000 hours. No filters to clean. No bulbs to replace. In a garage full of dust and temperature swings, that matters.

8.4ms input lag at 1080p/240Hz — You won’t feel any delay between your swing and what shows up on screen. If you game on this thing (and you will), it’s fast enough.

The Price Problem

$2,899. That’s what it goes for at authorized retailers (Golf Bays USA, Swing Sphere, Top Shelf Golf).

That’s not cheap.

You can get the BenQ TK710STi for $2,199 and get 4K laser with a shorter feature list (no Golf Mode, no Auto Screen Fit, 3,200 lumens instead of 4,000). You can get the LK830ST for $2,499 with an ultra-short throw that sits almost against the wall. You can even grab the AH700ST for $2,299 and get 1080p with Auto Screen Fit.

So what do you actually pay for with the AK700ST?

The $700 premium over the TK710STi buys you: 800 more lumens, motorized zoom, Golf Mode color calibration, IP5X dust protection, curved screen warping, and that Auto Screen Fit party trick. Oh, and the 95% Rec.709 color accuracy is the best in BenQ’s golf lineup.

For a first-time builder, that $700 saves you two hours of ladder time and three YouTube tutorials. For an upgrade, it saves you from taking the whole ceiling mount down because you were off by two degrees.

It’s not cheap, but it’s worth it if you value your time.

Who Is This For?

The first-time builder. You’ve never hung a projector. You don’t want to learn. The Auto Screen Fit makes installation idiot-proof. Point it at the screen, press the button, you’re done. That alone is worth the money.

The curved screen builder. The curved warping feature is unique in the BenQ lineup. If you’re building a bay with a curved impact screen (Carl’s Place, SIG, Par2Pro — they’re all doing curved now), this is the projector you want.

The multi-use room guy. The AK700ST has eARC for Dolby Atmos 7.1 passthrough and a 10W speaker. You can watch movies on it. You can game on it. The Auto Screen Fit lets you switch between aspect ratios with one button — 16:9 for the movie, 16:10 for the sim. That’s a level of convenience that doesn’t exist on any other projector at this price.

The “set it and forget it” guy. 20,000 laser hours. No filters. No bulbs. No maintenance. Mount it once, never touch it again.

Who Should Skip It?

The budget builder. If you’re building a $1,000 setup with a Spornia net and a Garmin R10, don’t spend $2,899 on a projector. Get the TK710STi or even the AH700ST and put the difference toward a better launch monitor.

The ultra-short throw purist. The LK830ST sits at 0.5 throw ratio — the projector can basically touch the wall and fill a 10-foot screen. If your room is shallow front-to-back, the LK830ST might fit better. But you lose Auto Screen Fit and curved warping.

The commercial operator. For a golf facility running 12 hours a day, the LK936ST at $4,899 has 5,100 lumens, optical lens shift, and IP6X sealing. The AK700ST is a home projector. Don’t buy it for a business unless it’s a single bay.

How It Compares

Quick reference for the BenQ 4K lineup:

Model	Price	Brightness	Throw	Auto Fit	Best For
TK710STi	$2,199	3,200 lm	0.69-0.83	No	Value 4K + streaming built in
LK830ST	$2,499	4,000 lm	0.50 UST	No	Ultra-tight rooms, UST preferred
AK700ST	$2,899	4,000 lm	0.69-0.83	Yes	Easiest setup, curved screens, best color
LK936ST	$4,899	5,100 lm	0.81-0.89	No	Commercial, bright rooms, lens shift

The Real Talk

Ask anyone who’s built a sim what the worst part was, and they’ll tell you the same thing: mounting the projector. Forum build threads are full of it. The pattern is always the same — mount it, climb down, check, climb back up, move it an inch, climb down, check, repeat. Builders consistently report 1-2 hours of iterative adjustment for a standard projector. A lot of them end up using digital keystone to fix a tilt they left themselves.

The AK700ST changes that. Owners consistently report installation times around twelve minutes from opening the box to a perfectly aligned 16:9 image on the screen.

Twelve minutes.

If you’ve mounted a projector before, you understand what that means. If you haven’t, trust me — it’s the difference between “that was annoying” and “that was the easiest part of the build.”

The AK700ST won the COMPUTEX Best Choice Award in June 2026. That’s a global tech award, not a golf one. It won because Auto Screen Fit is genuinely innovative, not because it’s a good golf projector. (It’s also a good golf projector.)

The one real downside: the input lag at 4K/60Hz is 33.4ms, which is noticeable if you’re sensitive to it. At 1080p/240Hz it drops to 8.4ms, which is fine. If you’re running GSPro at 4K on a high-end PC, you’ll feel the difference. Run it at 1080p for gaming and you won’t.

Also, the 10W speaker is fine for setup testing but you’ll want a real audio solution for actual use. The eARC passthrough makes that easy — one HDMI cable to a soundbar or AV receiver.

The Final Verdict

The BenQ AK700ST is the easiest golf simulator projector to install that has ever existed.

This is a statement about a physical fact, not hype. There is a button on the remote that makes the projector set itself up. No other projector at any price does that.

The picture is excellent — 4K, 4,000 lumens, 95% Rec.709 color, Golf Mode, curved warping. The laser engine runs 20,000 hours with zero maintenance. The input lag is fast enough for gaming. The eARC handles 7.1 audio. It’s a complete package.

The price is $2,899. That’s not an impulse buy. But if you’re building a $5,000-$10,000 simulator setup, the difference between this and a $2,199 TK710STi is the difference between a headache-free install and a Saturday afternoon on a ladder.

You know what your time is worth. I can’t answer that for you. But I can tell you this: if someone asks you “how do I mount this projector?” — tell them to buy the AK700ST. Because they won’t need to ask anyone else for help.

If you’re building a sim and you want to skip the frustration, here’s the link. Buy it. You’ll thank me when you’re done in 12 minutes.
