I could not get it to auto. Focus on an 8 / 8 screen. I didn't know if it was my garmin R50 or the projector but I manually\n Got it to work on a 8 / 8.

Who It's For
Is the LK936ST Right for Your Build?
The "No Compromises" Builder
You are building the best sim room money can buy. GCQuad, full enclosure, dedicated room. The LK936ST pairs 5,100 ANSI lumens with 4K resolution for a premium build.

Which One for Which Room
Shorter Room: AK800ST
The shortest throw of the three, 9 ft 2 in to 11 ft 1 in for a 10 ft x 7 ft 6 in 4:3 screen. It has no lens shift, so center the mount left to right on the screen.
Bright Room: AK900ST
6,000 ANSI lumens, the brightest of the three: 20% more than the AK800ST and 18% more than the LK936ST.
Off-Center Mount: LK936ST or AK900ST
Both have optical lens shift, vertical +/-60% and horizontal +/-23%, so the picture moves without moving the projector.
Curved Screen: AK800ST or AK900ST
Auto Screen Fit 2.0 uses a built-in camera to fit the picture to your screen, and Smart Warping adds control points for a curved screen.
Long Cable Run: LK936ST
The only one of the three with an HDBaseT input, which carries 4K from the PC over one cable.
Gaming: AK800ST or AK900ST
4.8 ms input lag at 1080p 240Hz, against 16.7 ms for the LK936ST.
Setup Guide
Get the Most Out of Your LK936ST
Six tips to get a perfect image from day one.
Ceiling Mount It
The BenQ ceiling mount ($99) is the optional ceiling mount BenQ lists for this projector. Overhead mounting eliminates swing interference and keeps cables clean.
Use the Lens Shift
The LK936ST's V +/-60% and H +/-23% lens shift is set with knobs on the projector. Mount it off-center or at a non-ideal height and line up the image without moving the projector.
Use HDBaseT for Long Runs
For a long run from your PC, use the HDBaseT port with an HDBaseT transmitter at the PC and one Ethernet cable. BenQ rates 4K up to 50 m (about 164 ft).
Enable Golf Mode
In picture settings, select Golf mode. BenQ designed it for golf simulators to optimize blue sky and green grass colors.
Pair with Quality Enclosure
On a 15 ft deep 10 x 15.5 ft Carl's Pro, the LK936ST hangs from the front top bar on Carl's Projector Frame Mount, no ceiling mount needed. See our golf simulator enclosures to build the bay.
Connect External Audio
The LK936ST supports eARC with Dolby Atmos passthrough and S/PDIF output. Connect a soundbar or surround system for an immersive golf and home theater experience.
Watch Before You Mount
How to Ceiling Mount the LK936ST
BenQ walks through finding the mounting spot on an LK936ST: test the throw on the floor, size the picture an inch larger than the screen, then mark the ceiling from the lens center.
Lens shift versus keystone on the LK936ST: 60% vertical and 23% horizontal optical shift, and why to use it before any digital correction.

Common Questions
Frequently Asked Questions
How bright is the BenQ LK936ST and will it handle ambient light?
The LK936ST outputs 5,100 ANSI lumens from a laser light source; of the 4K BenQ projectors we carry, only the AK900ST (6,000) is brighter. BenQ rates it for bright images in daytime rooms with the lights on. For dedicated sim rooms with controlled lighting, the image quality is exceptional.
What is the throw distance for the BenQ LK936ST?
The LK936ST has a 0.81-0.89:1 throw ratio with 1.1x optical zoom. For a 100-inch screen, the projector sits approximately 5.9 to 6.5 feet from the screen. For a 120-inch screen, approximately 7.1 to 7.8 feet. For a 150-inch screen, approximately 8.8 to 9.7 feet. For a 200-inch screen, approximately 11.8 to 12.9 feet. If you need the projector closer to the screen, consider the AK700ST (0.69-0.83:1) or the LK830ST (0.496:1 short throw).
Can I ceiling-mount the BenQ LK936ST?
Yes. BenQ lists its CM00G3 ceiling mount ($99) as an optional accessory for the LK936ST. The mount allows you to install the projector above and behind the hitting area. The LK936ST's lens shift (V +/-60%, H +/-23%, set with knobs on the projector) gives you flexibility in ceiling-mount positioning, so you do not need the mount to be perfectly centered or at an exact height.
What is HDBaseT and why does it matter?
HDBaseT sends video, audio, and RS-232/IR control over one Ethernet cable from an HDBaseT transmitter at your PC to the projector's HDBaseT port. BenQ's manual rates 4K signals up to 50 meters (about 164 feet) and 1080p or 1920x1200 signals up to 100 meters (328 feet) on Cat5e/Cat6A cable. If your sim PC is in a different room, closet, or equipment rack, HDBaseT replaces a long HDMI run.
What is the BenQ LK936ST laser life?
The LK936ST uses a laser light source rated at 20,000 hours in normal mode. There is no lamp to replace, and the sealed engine needs no filter changes. At 4 hours of daily use, 20,000 hours is about 13.7 years.
How does the LK936ST compare to the BenQ AK700ST?
Both are 4K laser golf simulator projectors from BenQ. The LK936ST ($4,899) adds 5,100 lumens, HDBaseT, DisplayPort, lens shift (V +/-60%, H +/-23%; the AK700ST has none), and pro-grade connectivity. The AK700ST ($2,899) delivers 4,000 lumens with a shorter throw ratio (0.69-0.83:1 vs 0.81-0.89:1), making it better for very tight rooms. Choose the LK936ST for maximum brightness, installation flexibility, and commercial-grade setups. Choose the AK700ST for compact spaces and a lower price point.
Is 4K resolution necessary for a golf simulator?
4K resolution (3840x2160) provides four times the pixel density of 1080p. On large screens (100 inches and up), the difference is clearly visible in course graphics, green reading, and club data overlays. If you are investing in a premium launch monitor and software, consider a 4K projector for the sharpest picture. The LK936ST's 5,100 lumens also mean you are not sacrificing brightness for resolution.
What screen size should I use with the LK936ST?
For most home simulators, a 100-150 inch impact screen delivers the best combination of immersion and image quality. Choose the final screen size around room dimensions, screen gain, and ambient-light control.
Can I use the LK936ST with any golf simulator software?
Yes. The LK936ST connects via HDMI 2.0b, DisplayPort, or HDBaseT and works with any simulator software including GSPro, E6 Connect, TGC 2019, Creative Golf 3D, Awesome Golf, and more. It is simply a display device -- compatible with any PC-based or console-based simulator setup.
How does Top Shelf Golf ship the LK936ST?
Top Shelf Golf offers free shipping on most orders within the contiguous 48 states. The projector weighs 15.4 lbs (7 kg).
Does the LK936ST have a built-in speaker?
Yes, it has a built-in 10W speaker. It also supports eARC with Dolby Atmos passthrough and includes S/PDIF output for connecting external surround sound systems. For most simulator setups, an external sound system delivers a better audio experience, but the built-in speaker works for basic use during setup and testing.
Does Top Shelf Golf offer financing for the BenQ LK936ST 5100-Lumen 4K Laser Short Throw Golf Simulator Projector?
Yes. Top Shelf Golf offers financing through Affirm with flexible monthly payment options. Select Affirm at checkout to check your rate -- it takes seconds and won't affect your credit score. 0% APR options may be available depending on eligibility.
Does BenQ offer a warranty on the LK936ST?
Yes. BenQ America provides a 3-year limited warranty on parts and labor from the original purchase date. Top Shelf Golf is an authorized BenQ dealer, so your warranty is fully backed. See our return policy for additional details.
