BenQ LK936ST - 4K UHD Short-Throw Golf Simulator Projector | 5,100 Lumens
The Premium Dual-Purpose Golf Simulator and Home Theater Projector.
The BenQ LK936ST is BenQ's flagship golf simulator projector — brighter, more flexible, and more capable than any projector in the lineup below it. With 5,100 ANSI lumens of laser brightness, a 0.81–0.89 short throw ratio, and an industry-leading ±60% vertical / ±23% horizontal lens shift, it's the projector that fits where others can't, performs where others fade, and doubles as a stunning home theater when the round is over.
Where the LK830ST is built for tight spaces and floor mounting, the LK936ST is engineered for ceiling-mount and overhead installations — the most common configuration in dedicated simulator rooms, custom builds, and commercial bays. From 14 to 15 feet away, it fills a screen nearly 10 feet tall. And because the lens shift is optical rather than digital, shifting the image to compensate for an off-center mount introduces zero distortion and zero resolution loss — something keystone correction alone can't deliver.
BenQ calls it a "sim-theater" projector, and the description is earned. The LK936ST is the projector you buy when you want the golf simulator to run in the morning and a 4K HDR movie theater to take over at night — without touching a setting, moving a piece of equipment, or making any compromises on either experience.

Screen Compatibility & Pairing Notes
The LK936ST is fully compatible with all Golf Sim Depot impact screens and SIG Studio enclosures. Because of its 0.81–0.89 throw ratio, it requires more room depth than the LK830ST. Recommended pairings:
| Enclosure / Screen | Screen Width | Recommended Throw Distance |
|---|---|---|
| SIG10 Studio (10'1" screen) | 10'1" | ~8–9 feet |
| SIG12 Studio (11'5" screen) | 11'5" | ~9–10 feet |
The SIG8's 7'7" screen can be paired with the LK936ST but requires confirming room depth allows sufficient throw distance. Contact our team for a free setup consultation.

Frequently Asked Questions
What's the key difference between the LK936ST and the LK830ST?
The LK830ST has a 0.5 ultra-short throw ratio — designed for floor mounting in tight spaces with as little as 4–5 feet of throw distance. The LK936ST has a 0.81–0.89 throw ratio, meaning it needs more room depth (10–16 feet typically) but delivers 1,100 more lumens, a large optical lens shift for off-center mounting, zoom capability, HDBaseT, and full home theater audio support. The LK830ST is for tight spaces and floor mounts; the LK936ST is for ceiling mounts in dedicated rooms.
Why does optical lens shift matter more than keystone correction?
Keystone correction is digital — it compensates for an angled image by cropping and stretching pixels, which reduces effective resolution and can soften the image. Optical lens shift physically moves the lens to shift the image, maintaining full 4K resolution with zero distortion. When mounting a projector off-center from your screen, always use lens shift first, then apply minimal keystone if any additional correction is needed.
Can I use the LK936ST in my garage simulator?
Yes, if your garage is deep enough. Most two-car garages are 20+ feet deep, which gives plenty of room for the LK936ST's throw ratio. Measure from your planned ceiling mount position to the screen and confirm throw distance using BenQ's planner before purchasing. The IP5X sealed engine handles garage humidity and dust.
Does Golf Mode make a real difference?
Yes — especially on impact screens. Golf simulator screens are designed to stop a ball, not optimize image color. BenQ's Golf Mode compensates for the way impact screen material absorbs and diffuses light by boosting the blue and green channels and correcting the purple fringing that laser projectors can exhibit. The result is noticeably more natural-looking fairways, sky, and rough compared to using a generic picture mode.
How does the home theater performance compare to a dedicated home theater projector?
At 5,100 lumens, the LK936ST is significantly brighter than typical home theater projectors (which usually target 1,500–2,500 lumens). In a dark room, that extra brightness means you'll need to turn the lamp power down. In any room with ambient light, it's a major advantage. The 92% Rec.709 color accuracy, HDR10, HLG, eARC, and 3,000,000:1 contrast ratio all deliver a genuinely excellent home theater experience — just calibrate your picture mode for the room conditions.
What does HDBaseT do and do I need it?
HDBaseT lets you run 4K video, audio, RS-232 control, and LAN signals from your simulator PC to the projector over a single Cat5e/Cat6 ethernet cable — up to 100 meters (328 feet). For clean permanent installations where you want the PC in a closet or adjacent room with no visible cables running to the projector, HDBaseT is the professional's choice. You'll need a compatible HDBaseT transmitter (sold separately) at the PC end.
What's the warranty?
The BenQ LK936ST carries a 3-year manufacturer warranty. Contact Golf Sim Depot support for any warranty claims and we'll coordinate with BenQ on your behalf.
Choose options
BenQ's flagship. More lumens. More flexibility. No compromises.
1,100 lumens brighter than any other BenQ golf simulator projector. If your bay has windows, overhead lights you can't fully kill, or you're building a commercial space where the lights stay on — this is the projector that handles it without washing out the image.
The LK936ST shifts the image up to 60% vertically and 23% horizontally without touching the projector. If ceiling obstructions, beams, or room geometry prevent a perfectly centered mount, lens shift moves the image to fill your screen without digital keystone softening. A feature no other BenQ golf projector offers.
3840×2160 with 8.3 million pixels and 92% Rec.709 color accuracy. Golf Mode corrects color fringing specifically for course simulation — accurate greens, true-to-life blues, no purple fringing that cheaper projectors show in golf software.
Run 4K video, audio, RS-232, and LAN control through a single RJ-45 cable up to 328 feet. For permanent installs in garages, basements, or commercial bays where running multiple cables is impractical, HDBaseT makes the wiring clean and simple.
Connect a compatible soundbar or AV receiver via eARC for immersive surround sound — one cable handles video and audio together. When you're done golfing, it doubles as a premium home theater projector.
IP5X dustproof sealed engine runs reliably from 32–104°F with no filter replacements. The laser light source is rated for 20,000 hours — years of daily use with no maintenance, no bulb costs, no degradation in brightness or color.

FAQ
Let customers speak for us
I’ve tested multiple overhead launch monitors looking for the best mix of accuracy, reliability, and price. Nothing has come close to the ProTee. It simply works every time. The tracking is fast, consistent, and doesn’t require constant tweaking or recalibration like others I’ve owned. The software is a standout too: intuitive, polished, and far more advanced than I expected at this price point.
For anyone building a home simulator and wanting overhead performance without spending 20k, this is the new standard. ProTee absolutely nailed it.
Have had the ProTeeVX set up for a little over a week and it's been amazing so far. Wasn't totally clear on the dimension requirements and Golf Sim Depot was super helpful through their chat feature and answered all my questions. Bundling this, the protective cover, GSPro AND getting two free swing cams is an incredible deal for a top quality product.
The best company to work with Kyle is very responsive and very easy to work with!!
I had questions about the Protee VX so I called Golf Sim Depot. Kyle answered the phone right away and answered all my questions. I am working on revamping my simulator so he also spent some time talking to me about it and some of the choices I have for the revamp. I bought the Protee VX from Golf Sim Depot and couldn't be happier.
Great company with quick delivery, prompt answers to my questions! Will highly recommend them!
I've been a business owner since I was 12 years old; customer service is the blood that flows for the success of any business. Kyle and his team at Golf Sim Depot have met those standards, from choosing the right sim for my space to following through when an issue arose with my screen. Thank you, Kyle; you have a customer for life.
ProTee vx is the new king of indoor launch monitors. If you want to know every detail of your golf swing then this is the one to purchase..
Couldn't be happier with the ProTee vx.
It is my second Softy. It is worth my health. I am 65. I have hit my share of fat shots. No one had any issue with smacking the club. The last straw was my friend hitting the raised back edge. The first is a little warn in the center - still usable but needs repair gluing the corners and edges after forcing it into a cut out in my mat. This new one fits like a well fitted golf glove. I could not be happier with the product. Regarding Golf Sim Depot: I have had several great experiences with Kylie upgrading from Skytrak to Uneekor EML and then Uneekor's Optix package. This Softy was derived quickly like all the other purchases.
Kyle knows sims. He worked with me and gave me insights that really helped me move my business in the right direction. My launch monitors arrived in less than a week, would highly recommend doing business with Golf Sim Depot.
Needed garmin r50 by certain date. Kyle made it happen even with holiday weekend. Would recommend to anyone looking to purchase.
I received my unit very quickly. Golf sim depot was very flexible and easy to deal with.
They will be the first place I go for any additional needs.
Respond well and fast to questions.
Great customer service. Worked with us very well.
Outstanding customer service and communication. Bought most of my setup here and they got everything to me on time or ahead of schedule.
These guys are great! Called on a Saturday and he went straight to UPS so I had the product on Monday. Very good pricing too. Highly recommend!
