BenQ AK800ST and AK900ST First Look: New 4K Golf Simulator Projectors

The full guide: Best golf simulator projectors

BenQ has two new 4K laser projectors built for golf simulators: the AK800ST at $3,999 and the AK900ST at $5,999. BenQ announced them on October 1, 2026 and says both go on sale later in October. Jay Lasco, host of Golf Simulator Videos, saw them at BenQ's launch event, where an AK800ST was running on a curved impact screen with the room lights on. This is a first look at what BenQ has published and where each one fits in a room. It is not a review: GSV will test both and publish a full review of each.

Specs are from BenQ's specification pages for each model, read on October 3, 2026. Prices and the on-sale timing are from BenQ's announcement. None of these figures has been measured by GSV yet.

The features BenQ highlights

• Auto Screen Fit 2.0. BenQ says the projector detects the shape and size of the screen, flat or curved, and fits the picture to it.
• Golf Mode 2.0. BenQ's picture mode for course colors. The spec sheets also list Bright Golf and HDR Golf modes.
• Screen Fill in six shapes. 16:9, 16:10, 3:2, 4:3, 5:4 and 1:1, so the picture shape can match a 4:3 or square screen.
• Scene memory. Five saved display profiles, switched with one button.
• Curved screens. BenQ lists corner fit and pixel mapping for screens that are not flat.
• Faster modes for games. 4K runs at 60 Hz. The 120 Hz and 240 Hz modes run at 1080p.

Throw distance: where each one hangs

Throw ratio is the distance from the lens to the screen divided by the width of the picture. Multiply the ratio by the picture width and you have the distance. These are the distances for a 16:9 picture:

Picture width	AK800ST, lens to screen	AK900ST, lens to screen
10 ft	6 ft 11 in to 8 ft 4 in	8 ft 1 in to 8 ft 11 in
12 ft	8 ft 3 in to 10 ft 0 in	9 ft 9 in to 10 ft 8 in
14 ft	9 ft 8 in to 11 ft 7 in	11 ft 4 in to 12 ft 6 in
16 ft	11 ft 0 in to 13 ft 3 in	13 ft 0 in to 14 ft 3 in

A 4:3 enclosure changes the numbers. To fill the height of a 4:3 screen, a 16:9 projector throws a picture wider than the screen, so it hangs further back than the table says. Two rooms from the GSV Sim Builder:

• 14 x 18 ft room, 10 ft ceiling, SIG12 enclosure: the AK800ST fills the screen from 10 ft 6 in to 12 ft 8 in. The builder hangs it 11 ft 7 in from the screen, 19 in behind the tee.
• 16 x 22 ft room, 10 ft 6 in ceiling, Carl's Place Pro 10 x 13: the AK900ST fills the screen from 13 ft 2 in to 14 ft 6 in. The builder hangs it 13 ft 10 in from the screen, 3 ft 10 in behind the tee.

Check either projector in your room

Same throw as the BenQ models you know

On BenQ's spec sheets the AK800ST has the same 0.69 to 0.83 throw range as the AK700ST, and the AK900ST has the same 0.81 to 0.89 range as the LK936ST, which also has lens shift. A mount position that works for the older model works for the new one. What changes is the brightness and the setup features: the AK700ST is 4,000 lumens against 5,000 for the AK800ST, and the LK936ST is 5,100 lumens against 6,000 for the AK900ST.

Which one for which room

These are reasons from the spec sheets. Which one looks better on a screen is a question for the reviews.

What we do not know yet

• Measured numbers. Brightness, input lag and color are BenQ's figures. GSV has not measured either projector.
• Lens shift on the AK800ST. Settled in GSV's AK800ST review: it has no lens shift, as its spec sheet says. The lens shift on its product page belongs to the AK900ST.
• The on-sale date. BenQ said later in October 2026. On November 7, 2026, Shop Indoor Golf sold the AK800ST and did not list the AK900ST yet.

Both reviews are out, with the install and setup in a simulator room: the AK900ST review and the AK800ST review.

Price and how to buy

The AK800ST is $3,999 and the AK900ST is $5,999. Shop Indoor Golf sells the AK800ST. For current pricing on the AK900ST, email GSV.
