BenQ LK830ST 4K Short Throw Laser Golf Simulator Projector

The BenQ LK830ST is a compact 4K laser projector designed for golf simulator rooms where space is limited but image quality still matters.

With 4,000 ANSI lumens, 4K UHD resolution, an ultra-short 0.496 throw ratio, and BenQ’s dedicated Golf Mode, the LK830ST can produce a large, bright, detailed image from a very short mounting distance. That makes it an excellent choice for smaller simulator rooms, garages, basements, and installations where projector depth is limited.

True 4K Detail in a Compact Space

The LK830ST delivers 3840 × 2160 4K UHD resolution, producing 8.3 million pixels of image detail across your impact screen.

That extra resolution helps bring out subtle course details such as grass texture, bunker edges, shadows, trees, and terrain changes, making modern golf simulator software look sharper and more immersive.

With 4,000 ANSI lumens and a rated 3,000,000:1 contrast ratio, the LK830ST also has enough output for large simulator screens while maintaining strong image depth and visibility in rooms with some ambient light.

Extremely Short Throw for 4K in Tight Spaces

The standout feature of the LK830ST is its 0.496 fixed throw ratio.

This allows the projector to create a large image while sitting much closer to the impact screen than models such as the AK700ST, AK800ST, or LK936ST.

That shorter mounting distance can be a major advantage in:

• Smaller golf simulator rooms

• Garages

• Basements

• Lower-ceiling installations

• Floor-mounted projector setups

• Rooms where ceiling depth is limited

BenQ specifically positions the LK830ST as a compact-space golf simulator projector, with support for both ceiling and floor mounting.

Designed for Golf Simulation

The LK830ST includes BenQ’s dedicated Golf Mode, which is tuned to reproduce the natural colors found throughout a golf course.

Fairways, greens, rough, bunkers, trees, and terrain appear more natural and balanced than they typically would using a general-purpose presentation projector.

The projector also covers 93% of the Rec.709 color gamut, providing strong color performance for golf simulation, movies, sports, and gaming.

Screen Fill for Custom Simulator Screens

Golf simulator impact screens do not always follow a standard 16:9 format.

The LK830ST includes BenQ’s Screen Fill feature with support for:

• 16:9

• 16:10

• 4:3

• 1:1

• 5:4

This gives you more flexibility when designing around custom simulator screen dimensions and helps make better use of the available impact-screen area.

Golf First, Entertainment Ready

The LK830ST is designed for golf simulation first, but it is also well suited for multi-purpose entertainment rooms.

Dedicated picture modes include Golf, Cinema, HDR10, HLG, Game/Entertainment, sRGB, Presentation, and more, making it easy to transition from simulator use to movies, sports, or gaming.

It also supports low-latency gaming with input lag as low as:

• 4.2ms at 1080p / 240Hz

• 8.3ms at 1080p / 120Hz

• 16.7ms at 1080p / 60Hz

• 16.7ms at 4K / 60Hz

Long-Life Laser Performance

The LK830ST uses a laser light source rated for approximately 20,000 hours in Normal mode and 30,000 hours in ECO mode.

It also features an IP6X sealed optical engine, helping protect internal components from dust and making it especially well suited for garages, commercial installations, and other environments where dust can be a concern.

Pixel Golf Recommendation

The LK830ST is one of the best BenQ options for customers who want 4K resolution but need an extremely short projector mounting distance.

Its 0.496 throw ratio is substantially shorter than the 0.69–0.83 range of the AK700ST and AK800ST, allowing the projector to sit much closer to the impact screen.

It also delivers the same 4,000-lumen brightness as the AK700ST while prioritizing compact placement over automated setup features. The AK700ST adds conveniences such as Auto Screen Fit and more installation automation, while the LK830ST focuses on maximizing usable room depth and providing true 4K performance in smaller spaces.

For customers building in a garage, basement, smaller simulator room, or any space where projector distance is a major constraint, the LK830ST offers a compelling combination of 4K resolution, laser brightness, compact placement, and golf-specific image quality.
