Why Golfers Choose the AK800ST
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.
5,000 ANSI Lumens
Laser light source rated for 20,000 hours in Normal mode and 30,000 hours in Eco mode.
Motorized Zoom
0.69-0.83:1 throw with 1.2x motorized zoom you adjust from the remote, so the projector never has to move.
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.
IP5X Sealed Engine
The laser engine is sealed against dust. No filters to clean and no bulbs to replace.
AK800ST Throw Distance and Placement
Here is the math for a 4:3 impact screen 10 ft wide x 7 ft 6 in tall.
- The AK800ST'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: 0.69 x 13.33 ft = 9.2 ft, and 0.83 x 13.33 ft = 11.1 ft.
- Use the 1.2x zoom to land in that range, then set Screen Fill to 4:3.
Is the AK800ST Right for Your Build?
Six setups this projector fits best.
4K Sim Room Builder
You want a true 4K picture and a laser rated for 20,000 hours, with nothing to replace.
Rooms That Are Not Fully Dark
5,000 lumens, plus an Ambient Light Enhancer that adjusts color and saturation to room light.
Curved Screen Owners
Auto Screen Fit 2.0 aligns the picture first, then Smart Warping adds control points to calibrate a curved screen.
Stepping Up from the AK700ST
You want 1,000 more lumens without moving the mount. Both use a 0.69-0.83:1 lens.
Sim Room by Day, Theater by Night
Golf Scene Memory saves up to five display profiles, so switching from golf to a movie takes one button. Cinema, Game and Sports modes are built in.
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.
Paired with 3,000,000:1 contrast, so fairways, sand and sky keep their color and depth on a big screen.

Frequently Asked Questions
BenQ rates the AK800ST at 5,000 ANSI lumens, 1,000 more than the AK700ST. 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 AK800ST sits about 9 ft 2 in to 11 ft 1 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 0.69 to 0.83 x 13.33 ft gives that range.
Both are true 4K short throw laser projectors with the same 0.69-0.83:1 lens, so they mount in the same spot. The AK800ST ($3,999) adds 1,000 lumens (5,000 vs 4,000), three HDMI 2.1 inputs and Auto Screen Fit 2.0 with a built-in camera. The AK700ST ($2,899) costs $1,100 less.
The AK900ST is the step up: 6,000 lumens, a 0.81-0.89:1 lens with 1.1x zoom, and lens shift of plus or minus 60% vertical and 23% horizontal.
The AK800ST is smaller and lighter (15.3 in wide and 13.0 lb vs 20.5 in and 22.5 lb) and sits about 9 to 11 ft from a 4:3 screen 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 AK800ST 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 AK800ST. We also carry Carl's Place universal projector mounts, rated to 50 lb, with drop options for taller rooms.
