Auto Screen Fit
THE PROJECTOR THAT ALMOST INSTALLS ITSELF
BenQ's auto-adjust Screen Fill feature corrects the image geometry with a single button press. Mount the projector, press the auto-adjust button, and it sizes and squares the image to your screen. No climbing a ladder to nudge corners, no taping off alignment marks. The single biggest install time-saver in the projector category.
True 4K + Laser In One Unit
4K UHD LASER PROJECTION UNDER $2,500
True 4K UHD resolution (3840 x 2160) from a laser light source. Most 4K projectors at this price still use lamp engines with 5,000-hour bulb replacements. The LK830ST runs a laser rated for 20,000+ hours, zero bulb swaps for the practical life of your sim. 4K + laser + auto-keystone at this price tier did not exist in the golf sim projector market until this model.
0.5:1 Ultra-Short Throw
100-INCH IMAGE FROM 3.6 FEET AWAY
Fixed 0.5:1 throw ratio projects a 100-inch image from just 3.6 feet away. Tighter than any other 4K projector in the BenQ golf sim lineup. Low ceilings, compact garages, tight enclosures, this is the 4K projector that fits where standard short-throws cannot.
4,000 Lumens For Ambient Light
BRIGHT ENOUGH FOR ROOMS THAT AREN'T CAVES
4,000 ANSI lumens at 4K resolution means you can run this projector in a room with stair light, overhead fluorescents, or windows without partial blinds. Most 4K projectors under $3,000 top out at 3,200 lumens. The LK830ST gives you the brightness tier that handles multi-purpose sim rooms.
Easier Install Than You Think
MOUNT, PLUG, AND HIT IN UNDER AN HOUR
Most home sim owners install this projector themselves in 30-60 minutes. Mount it, run one HDMI cable to your gaming PC, plug in power, press the auto-adjust button, that's it. If you've installed a ceiling fan or a TV mount before, this is easier. If you'd rather not DIY, our SimSquad team walks you through the whole install on a call.
From Our SimSquad
WHO THE LK830ST IS FOR
The LK830ST fills a gap we've been waiting for: a 4K laser projector with ultra-short throw at a price that makes sense for home sim builds. If your room is tight and you want 4K without compromising on throw distance, this is the one. The laser engine means no lamp replacements for the life of the projector. If your room has enough depth for a 0.69-0.83 throw ratio and you want to save, the AK700ST does the job at $400 less.
What is the BenQ LK830ST?
The BenQ LK830ST is a true 4K UHD laser short-throw projector built for golf simulator rooms. 4,000 ANSI lumens, a fixed 0.5:1 ultra-short throw ratio, laser light source rated for 20,000+ hours, and BenQ's auto Screen Fill for fast alignment. The only 4K laser projector in the BenQ golf sim lineup at this price tier.
Why Choose the BenQ LK830ST?
Honest framing: the LK830ST combines the three specs most sim builders want and usually have to compromise on: 4K resolution, laser longevity, and ultra-short throw. If 4K resolution matters but your room is too tight for a 0.69-0.83 throw ratio, this is the projector that fits. If you have the room depth and want to save, the AK700ST 4K is $400 less with a lamp engine. If you need commercial-grade lens shift and 5,100 lumens, jump to the LK936ST 4K.

Frequently Asked Questions
Yes. The BenQ LK830ST includes BenQ's auto Screen Fill feature. Mount the projector, press one button, and the unit auto-corrects the image to fit your screen geometry. Critical install advantage over most competing projectors at this tier.
Most home sim owners install the BenQ LK830ST themselves in 30 to 60 minutes. Mount the projector to your ceiling or floor mount, run one HDMI cable to your gaming PC, plug in power, press the auto-adjust button, that's it. Our SimSquad team walks through any step on a call if you'd rather not DIY.
The BenQ LK830ST has a fixed 0.5:1 ultra-short throw ratio, which means a 100-inch image from just 3.6 feet away. This fits the tightest sim rooms, low ceilings, and compact enclosures. SimSquad will spec the right projector based on your specific room dimensions before you buy.
The BenQ LK830ST delivers 4,000 ANSI lumens. For most controlled indoor sim rooms with managed lighting, this is plenty. If your room has significant ambient light, daylight windows, or you're running a 150+ inch screen, talk to SimSquad about a higher-lumen option like the BenQ LK936ST.
Yes. The BenQ LK830ST has standard HDMI inputs and works with every simulator software platform we ship, including GSPro, E6 Connect, and TGC 2019. Software compatibility is handled by your gaming PC, not the projector. The BenQ LK830ST renders whatever the PC outputs.
The BenQ LK830ST works with standard universal projector mounts including our RoS Ceiling Projector Mount. For low-ceiling rooms where ceiling mounting isn't practical, our SwingShield Floor Enclosure is sized for projectors of this footprint.
