BenQ LK936ST 4K Short-Throw Blue Core Laser Simulation Projector
True 4K Golf + Cinema.
In One Projector.
You're building a sim bay that's also a home theater. Or a media room that needs to handle 4K movies on Tuesday and a 200-inch golf simulation on Saturday. Or a classroom, a corporate showcase, a high-end residential install where the room serves more than one purpose. The BenQ LK936ST is the dual-purpose 4K laser projector — 5,100 BlueCore laser lumens, true 4K UHD resolution, motorized lens shift, BenQ's exclusive Golf Mode color calibration, eARC Dolby Atmos passthrough, and HDBaseT connectivity for clean cable runs. The most fully featured projector in BenQ's golf simulator lineup, equally capable as a reference 4K home theater projector.
Built by BenQ — the world's #1 projector brand for four years running, trusted in homes, classrooms, boardrooms, simulation bays, and commercial installations worldwide. Dedicated golf-simulator projector line since 2021.
Three Things The LK936ST 4K Laser Projector Does Better Than The Competition.
What separates BenQ's flagship 4K short throw golf simulator projector from the rest of the lineup — and from any single-purpose 4K laser projector in this category.
True 4K UHD + Exclusive Golf Mode
3,840×2,160 native resolution, 8.3 million pixels per frame, with 4K upscaling for any input. Golf Mode picture preset corrects the purple fringing that affects other laser projectors on greens and blues.
Motorized Lens Shift, From The Floor
±60% vertical and ±23% horizontal motorized lens shift means you align it remotely after mounting — no ladder, no second person, no physical repositioning. Critical for ceiling-mount sim rooms.
Home Theater Built In
eARC Dolby Atmos passthrough, S/PDIF 5.1 surround output, HDBaseT for one-cable runs to 100 meters, 16.7ms input lag at 4K/60Hz. The sim room becomes a theater the moment the bay is closed.
You Probably Recognize Yourself In One Of These.
Three buyers we see for the LK936ST — and what makes the dual-purpose 4K laser the right fit for each.
You Want A Sim Bay That's Also A Home Theater
Dual-purpose dedicated room
- You don't want to dedicate a room to ONLY golf simulation
- You want the same room to play 4K HDR movies with cinema-grade color
- You want premium audio — Dolby Atmos, surround, the whole package
Why this fits: Golf Mode for sim, FILMMAKER-grade picture modes for cinema, eARC Dolby Atmos for surround sound — switched from the remote in seconds.
You're Installing In A Permanent Ceiling Mount
Premium home bay or commercial install
- You're mounting it high and tight to the ceiling — alignment after install matters
- You want zero-maintenance laser life — 20,000 hours, no lamp swaps
- You want HDBaseT for a single clean cable run to your AV rack
Why this fits: motorized lens shift, IP5X-sealed BlueCore laser, HDBaseT to 100m, 3-year warranty. Built to install once and run for years.
You Need 4K, And You Need Brightness
Larger screens, lit rooms, or 4K gaming
- You're projecting on a 150"+ screen and need the lumens to fill it cleanly
- Your room can't be fully darkened during sim use (ambient light is a factor)
- You game on a 4K console or PC and want 16.7ms input lag at 4K/60Hz
Why this fits: 5,100 ANSI lumens at true 4K — bright enough for large screens and lit rooms, fast enough for console and PC gaming.

What You're Actually Getting.
True 4K UHD + 4K Image Upscaling
True 4K UHD (3,840 × 2,160) via BenQ's 0.47" single-DMD DLP — 8.3 million distinct pixels per frame, four times the detail of Full HD. Every fairway texture, bunker edge, and green contour renders with definition 1080p can't approach at large screen sizes. 4K Image Upscaling Technology automatically enhances any non-native 4K source to 4K quality. Input lag holds at 16.7ms at both 1080p/60Hz and 4K/60Hz.
Exclusive Golf Mode — Corrects Purple Fringing
BlueCore laser technology produces exceptional color saturation — but laser projection can introduce unwanted purple fringing on the greens and blues that dominate golf simulation software. BenQ worked with color experts to develop an exclusive Golf Mode that corrects this fringing using the blue and green color profiles of popular golf software, delivering naturally accurate sky blues and fairway greens. 92% Rec.709 color via dual color wheels keeps cinema, gaming, and presentation modes cinematic-grade.
Motorized Lens Shift, From The Remote
Manual lens shift means adjusting a knob on the projector itself while someone watches the screen. Motorized lens shift means you do it from the floor, with the remote, in seconds. The LK936ST has ±60% vertical and ±23% horizontal motorized lens shift. For ceiling-mount sim rooms, this is the difference between a one-person install and a two-person ladder job. 3D keystone correction (±40° V & H) and Corner Fit handle remaining alignment from any installation position.
BlueCore Laser + HDBaseT + eARC Dolby Atmos
BenQ's BlueCore laser technology uses dual color wheels with an additive yellow segment for RGBY spectra that single-wheel laser projectors can't match. 20,000 hours of laser life — no lamp swaps, no scheduled downtime, IP5X dustproof sealed. HDBaseT delivers video, audio, RS-232, and LAN over a single RJ-45 cable up to 100 meters. eARC enables Dolby Atmos passthrough via HDMI. S/PDIF 5.1 surround output. Extron, Crestron, AMX, and PJ-Link compatible.
What Ships With The LK936ST
Projector body, remote, install hardware, and the cables you need to get up and running. Lens is built-in — no separate lens purchase required (unlike the BR9708).
- BenQ LK936ST 4K laser projector
- Remote control with battery (RCA011)
- Power cord (1.8m)
- HDMI cable (1.8m)
- Installation guide + warranty card
- Built-in 10W speaker
Important: Power draw is 440W typical — worth factoring into circuit planning for a dedicated sim room. In Eco mode (33dB), it's quieter and more efficient than Normal mode (40dB) with no meaningful image-quality difference for most installs.
The LK936ST is a 15.4-pound ceiling-install or floor-mount projector with a 0.81–0.89 short throw ratio. Confirm your throw distance and mount before purchasing — call (833) 796-4777 and we'll walk through your room with you.
BenQ LK936ST Throw Distance By Screen Size.
Throw distance ranges for the LK936ST short throw 4K projector. Use this to verify your installation distance before ordering — and remember the motorized lens shift adds flexibility within these ranges.
| Screen size | Min. distance | Max. distance | Notes |
|---|---|---|---|
| 120" | 7.1 ft (2.2m) | 7.8 ft (2.4m) | Standard simulator bay |
| 130" | 7.7 ft (2.3m) | 8.4 ft (2.6m) | Larger bay setup |
| 150" | 8.9 ft (2.7m) | 9.8 ft (3.0m) | Where 5,100 lumens starts to shine |
| 170" | 10.1 ft (3.1m) | 11.1 ft (3.4m) | Ideal for this brightness level |
| 200" | 11.9 ft (3.6m) | 13.0 ft (4.0m) | Large-format bay or commercial |
Based on 0.81–0.89 throw ratio × screen width (16:9). The 1.1× zoom and motorized lens shift allow fine-tuning within these ranges without physically repositioning the projector. Call (833) 796-4777 with your room dimensions and we'll confirm the install.

Picking between LK936ST, LU935ST, and LK830ST?
The LK936ST is the right choice if you want true 4K, motorized lens shift, and eARC Dolby Atmos for a dual-purpose sim+theater room. The LU935ST ($3,999) trades 4K for WUXGA 1920×1200, adds 400 lumens, and is the brightest projector in the lineup — better for very large screens or rooms that can't be darkened. The LK830ST ($2,499) is the budget 4K option with fixed lens and no HDBaseT — solid value for a dedicated home sim where AV integration is simpler. Call (833) 796-4777 and we'll talk through what your room actually needs.
