Which BenQ Golf Simulator Projector Fits Your Room: AK700ST, AH700ST, or LK936ST?

Published 26 September 2026 · Updated 12 October 2026

Choose the AK700ST for 4K at a 0.69-0.83 throw ratio, the AH700ST for 1080p at the same throw range, or the LK936ST for more brightness and lens shift if its 0.81-0.89 throw range fits. The first two are rated at 4,000 ANSI lumens; the LK936ST is rated at 5,100. Start with the lens position your screen and swing area allow.

Start with throw ratio

A projector can have a great picture and still be wrong for the room. The lens has to sit somewhere it won't end up in the swing, cast a big shadow, or fight an overhead launch monitor for space.

Throw distance equals throw ratio multiplied by projected image width. For a 12-foot-wide, native 16:9 image, the AK700ST and AH700ST give a lens-to-screen range of 8.28-9.96 feet; the LK936ST gives 9.72-10.68 feet. These are calculated optical distances, not safe mounting positions. The ranges overlap, so a longer throw ratio doesn't automatically rule the LK936ST out.

If you use Screen Fill, cropping, or digital correction for a different screen shape, confirm the distance with BenQ's calculator and the selected mode. The visible cropped width may differ from the full projected width used by the throw ratio. BenQ's placement guidance explains the room and mounting constraints.

AK700ST

The AK700ST is a laser model rated at 4K UHD and 4,000 ANSI lumens. Its 0.69-0.83 throw range, Quick Focus, and Screen Fill presets for 16:9, 16:10, 4:3, and 1:1 are listed in BenQ's AK700ST specifications.

Those presets help with a screen that isn't TV-shaped. They don't establish swing clearance or replace a ceiling plan.

AH700ST: same placement, 1080p

The AH700ST shares the 4,000-ANSI-lumen rating and 0.69-0.83 throw range, but its resolution is 1920x1080. BenQ also lists Quick Focus and the same Screen Fill presets in the AH700ST specifications.

If your computer runs simulator software at 1080p, paying for a 4K projector won't turn that source into native 4K detail. Compare the installed quotes and your intended rendering resolution before paying for the AK700ST's extra pixels.

LK936ST: brighter, with lens shift

The LK936ST is rated at 5,100 ANSI lumens and 4K UHD, with a 0.81-0.89 throw range. BenQ lists vertical lens shift of -60% to +60% and horizontal shift of -23% to +23% in the LK936ST specifications.

Lens shift helps move the image when a beam, light fixture, or ceiling-mounted launch monitor obstructs the preferred mounting line. It doesn't move the hardware out of the club path. Check the manual's combined shift limits rather than assuming maximum horizontal and vertical shift are available together.

How much brightness do you need?

The higher output rating gives the LK936ST more scope for a large image or some ambient light. It doesn't guarantee a specific brightness on your impact screen: image size, projector mode, screen material, and room lighting all affect the result.

The golfer still needs enough light to set up safely and meet the launch monitor's requirements. Keep that light off the screen where you can.

Pick the model from your screen width

Mark the possible lens positions on your ceiling plan, using the full projected width and the intended aspect mode. Check each position against the golfer, mount, ceiling hardware, and launch monitor.

If both shorter-throw models fit, the AH700ST versus AK700ST decision is mainly about resolution and the actual purchase quote. The LK936ST is a candidate when its mounting range fits and lens shift or extra output solves a room problem.
