BenQ AK900ST Review: Our Take
Buy the AK900ST if you want BenQ's brightest 4K golf projector, 6,000 ANSI lumens with lens shift and the same 4.8 ms input lag, for a large screen or a bay with a lot of light, for $5,999.
It fits commercial bays and bright rooms with a 10 ft wide 4:3 screen and 10.8 to 11.9 ft between the lens and the screen, and installs where the mount sits off-center and needs lens shift.
- 4K UHD (3840 x 2160) picture at 6,000 ANSI lumens, with a 3,000,000:1 contrast ratio.
- Lens shift of plus or minus 60% vertical and plus or minus 23% horizontal for off-center mounts.
- Laser light source rated 20,000 hours in Normal and SmartEco modes and 30,000 hours in ECO.
- Input lag of 4.8 ms at 1080p 240Hz, 9.7 ms at 1080p 120Hz and 18.1 ms at 4K 60Hz.
- Three HDMI inputs with HDCP 2.3, Bright Golf and HDR Golf picture modes, and a 10W chamber speaker with a woofer.
- Pre-order: ships as soon as the first BenQ stock arrives.
- The 0.81 to 0.89:1 lens, shared with the LK936ST, is the longest throw among BenQ's 4K golf projectors: about 10.8 to 11.9 ft for a 10 ft wide 4:3 screen.
- At 10.2 kg (22.5 lb) it is the heaviest of the four and needs a mount rated for it; the BenQ CM00G3 mount is sold separately.
- Costs $2,000 more than the AK800ST for 1,000 more lumens and lens shift.
- Only HDMI-1 and HDMI-2 carry the 4K 60Hz ALLM signal; HDMI-3 is the third input.
Key numbers: 6,000 ANSI lumens, 4K UHD, 0.81 to 0.89:1 throw ratio, lens shift V 60% / H 23%, 3,000,000:1 contrast, 20,000-hour laser, 3 x HDMI, 10.2 kg.
Why Golfers Choose the AK900ST
True 4K UHD
3840 x 2160 resolution with 8.3 million addressable pixels, per BenQ. Course detail and data overlays stay sharp across a full impact screen.
6,000 ANSI Lumens
Laser light source rated for 20,000 hours in Normal mode and 30,000 hours in Eco mode.
4-Way Lens Shift
Plus or minus 60% vertical and 23% horizontal shift lets you mount high, low or off-center and keep full optical 4K.
Auto Screen Fit 2.0
A built-in camera detects your screen shape and size and aligns the picture. Smart Warping adds control points for curved screens.
Golf Mode 2.0
Golf, Bright Golf and HDR Golf picture modes with 97% Rec. 709 color coverage and 3,000,000:1 contrast.
Built for 24/7 Use
BenQ engineers the dust-sealed IP5X laser engine for non-stop commercial use, with remote device management.
AK900ST Throw Distance and Placement
Here is the math for a 4:3 impact screen 10 ft wide x 7 ft 6 in tall.
- The AK900ST's 16:9 picture must be 7 ft 6 in tall to cover the screen.
- That makes the full picture 13 ft 4 in wide.
- Distance = throw ratio x width: 0.81 x 13.33 ft = 10.8 ft, and 0.89 x 13.33 ft = 11.9 ft.
- Use the motorized 1.1x zoom and lens shift to land in that range, then set Screen Fill to 4:3.
Is the AK900ST Right for Your Build?
Six setups this projector fits best.
Commercial Sim Bays
You run bays all day. BenQ builds the AK900ST for 24/7 commercial use with remote device management.
Rooms That Are Not Fully Dark
6,000 lumens, plus an Ambient Light Enhancer that adjusts color and saturation to room light.
Tricky Mounting Spots
Your ceiling height or joists do not line up with the screen center. Lens shift moves the picture without tilting the projector.
Curved Screen Owners
Auto Screen Fit 2.0 aligns the picture first, then Smart Warping adds control points to calibrate a curved screen.
Gamers
BenQ lists input lag of 4.8 ms at 1080p 240Hz, 9.7 ms at 1080p 120Hz, 18.6 ms at 1080p 60Hz and 18.1 ms at 4K 60Hz.
Sim Room by Day, Theater by Night
Golf Scene Memory saves up to five display profiles. Cinema, Game and Sports modes, a 10W chamber speaker and a 10W woofer are built in.
Paired with 3,000,000:1 contrast, so fairways, sand and sky keep their color and depth on a big screen.

Which One for Which Room
Shorter Room: AK800ST
The shortest throw of the three, 9.2 to 11.1 ft for a 10 ft x 7.5 ft 4:3 screen. It has no lens shift, so plan the mount centered 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 Between Rounds: AK800ST or AK900ST
BenQ lists 4.8 ms input lag at 1080p 240Hz, against 16.7 ms for the LK936ST.
Get the Most Out of Your AK900ST
Six tips for a sharp, full-screen picture from day one.
Center with Lens Shift
Use lens shift to move the picture onto the screen instead of tilting the projector, so you keep full optical 4K.
Run Auto Screen Fit 2.0
The camera finds the screen and aligns the picture, and one-touch motorized autofocus sharpens it.
Set Screen Fill to 4:3
Pick the 4:3 output for a 4:3 impact screen so the picture matches the screen edges.
Pick a Golf Mode
Golf, Bright Golf and HDR Golf are built in. Bright Golf is the one to try in a room with some light.
Curved Screen? Warp Last
After the first alignment, Smart Warping adds control points so you can fine-tune a curved screen.

Frequently Asked Questions
BenQ rates the AK900ST at 6,000 ANSI lumens with a laser light source. Its Ambient Light Enhancer uses the projector's camera to read room light and adjust color and saturation. For the best contrast, keep direct light off the impact screen.
On a 10 ft x 7 ft 6 in 4:3 impact screen, the AK900ST sits about 10 ft 10 in to 11 ft 10 in from the screen. Its 16:9 picture must be 7 ft 6 in tall, so the full picture is 13 ft 4 in wide, and 0.81 to 0.89 x 13.33 ft gives that range.
Yes. BenQ lists lens shift of plus or minus 60% vertical and plus or minus 23% horizontal, so you can mount it high, low or off-center and move the picture onto the screen without losing optical 4K quality.
The AK900ST adds 1,000 lumens (6,000 vs 5,000) and lens shift, and BenQ builds it for 24/7 commercial use. The AK800ST is smaller and lighter (15.3 in wide and 13.0 lb vs 20.5 in and 22.5 lb) and sits closer to a 4:3 screen, about 9 to 11 ft instead of about 11 to 12 ft.
Yes. Auto Screen Fit 2.0 aligns the picture, then Smart Warping adds control points step by step so you can calibrate a curved screen.
4K is the resolution we recommend for a new sim room. A 4K UHD picture has 3840 x 2160 pixels, four times the 1920 x 1080 of 1080p, so text, flags and course detail stay sharp on a 10 ft wide screen.
Yes. The AK900ST is a display: your simulator PC connects over HDMI. It works with GSPro, E6 Connect, TGC 2019 and Awesome Golf (each sold separately) and other PC simulator software.
BenQ lists the CM00G3 universal ceiling mount as the optional mount for the AK900ST. The projector weighs 22.5 lb, so check the rating of any other mount before you use it.
