If you've been chasing that crisp, tour-broadcast-quality image on your simulator screen without blowing your entire simulator budget on one component, the BenQ LK935 5500 Lumens 4K Laser Projector β Refurbished, available at Grater Golf, is worth a serious look. This isn't a stripped-down "budget" projector dressed up to look premium β it's the real BenQ LK935, professionally refurbished, carrying the same 4K UHD laser engine that installers use in commercial simulator bays, golf entertainment lounges, and high-end home builds across the country.
For golfers building or upgrading a simulator room, the projector is often the piece that gets the least attention and causes the most regret. You can have the best golf launch monitor money can buy, a premium golf hitting mat, and a flawless impact screen β but if your image is dim, soft, or poorly placed, the whole experience falls flat. This guide walks through exactly what the BenQ LK935 offers, why the refurbished route makes sense, and how it fits into a complete simulator setup from Grater Golf.
Why the Projector Is the Heart of Your Golf Simulator Experience
Every golf simulator is really three systems working together: a launch monitor that reads your ball and club data, a hitting surface, and a display. Most golfers spend weeks comparing launch monitors golf shoppers care about most β Uneekor, Foresight, AccuGolf, GolfJoy β but treat the projector as an afterthought. That's a mistake, because the projector is what you actually look at for every single shot.
A weak projector washes out in ambient light, struggles with high-definition course graphics, and forces awkward mounting compromises in a garage or basement bay. The BenQ LK935 solves this with genuine laser brightness and true 4K resolution, so course graphics from platforms like E6 Connect or GSPro render the way they were designed to look β sharp fairways, real depth on the greens, and colors that don't fade out under overhead lighting.
What Makes the BenQ LK935 Different
The LK935 is built as a professional installation projector first, and a golf simulator projector second β which is exactly why it performs so well in a dedicated hitting bay.
5,500 ANSI Lumens of True Brightness
Brightness specs get thrown around loosely in the projector world, and "lumens" numbers from unbranded models are frequently inflated. The LK935's 5,500 ANSI lumens rating is independently measured and verified against BenQ's official U.S. specifications, so what you see on the box is what you get on the screen. That brightness matters most in rooms with windows, garage lighting, or an open basement layout where you can't fully control ambient light.
Native 4K UHD Resolution
At 3840 Γ 2160 native resolution, the LK935 renders simulator course textures, scorecards, and swing-analysis overlays with genuine clarity rather than upscaled softness. If you've ever squinted to read your carry distance or ball speed numbers on a lower-resolution setup, this is the fix.
Flexible Lens Placement for Real Rooms
Not every simulator bay has a perfect, symmetrical layout. The LK935's 1.6Γ optical zoom, combined with vertical lens shift of β60% to +60% and horizontal shift of β23% to +23%, gives you real flexibility to mount the projector off-center, on a side wall, or at an angle without distorting the image. Add BenQ's 3D keystone correction β vertical, horizontal, and rotational up to Β±30Β° β and most awkward garage or basement geometries become workable.
Built for Long-Term Simulator Use
The laser light source is rated for roughly 20,000 hours of normal operation, which for most home users translates into years of daily practice sessions without a bulb swap. Connectivity is equally practical for a simulator build: dual HDMI 2.0b inputs, DisplayPort, HDBaseT for long cable runs, LAN, USB-A, RS-232 for automation, and a 12V trigger for screen or lighting control.
Why Buy Refurbished from Grater Golf
A brand-new LK935 carries a premium price tag that puts it out of reach for a lot of home builders. Buying refurbished through Grater Golf changes that math without asking you to gamble on unknown sellers. Every refurbished unit listed is checked against official BenQ specifications, and Grater Golf clearly discloses the model's condition, so you know exactly what you're ordering before you commit.
This matters even more when a projector is going into a simulator setup, because it's not a standalone purchase β it has to work with your existing or planned golf simulator mats, impact screen, and enclosure. Buying refurbished from a specialist retailer that actually understands simulator geometry (rather than a general electronics marketplace) means you're getting sizing and placement guidance along with the hardware.
Planning Your Projector Placement Before You Buy
Throw ratio is the number that decides whether this projector will actually fit your room. It's calculated as the distance from the projector lens to your screen, divided by the visible image width. The LK935's throw ratio range of 1.36β2.18:1 gives you a solid working window for most home bays, garages, and basement conversions, but it's still worth confirming before you drill a single hole in the ceiling.
Before ordering, it helps to have these measurements ready:
-
Visible screen width and height
-
Desired aspect ratio (16:9 or the wider 21:9 display support the LK935 offers)
-
Room depth and ceiling height
-
Preferred mounting position relative to the hitting area
-
Clearance around your golf swing mat or golf hitting mats setup, so a mis-hit club never comes close to the lens
Grater Golf's team will check this starting geometry with you directly β you don't have to guess alone, and you don't have to be a low-voltage installer to get it right.
Building the Rest of Your Simulator Around the LK935
A great projector is only one piece of a simulator that actually performs like the real thing. Here's how the rest of the room typically comes together.
Choosing a Launch Monitor
Your launch monitor is what turns a swing into usable data β ball speed, spin, launch angle, and carry distance. Grater Golf carries a wide range of golf launch monitors for sale, including camera-based systems like the Uneekor launch monitor lineup, radar-based portable units, and overhead systems from AccuGolf and GolfJoy. If you're weighing overhead versus in-ground placement, the AccuGolf Hawkeye launch monitor is a popular dual-camera overhead option worth comparing against Uneekor's EYE series if you want a markerless, ceiling-mounted setup that keeps your floor space open around the hitting mat.
For golfers researching the best launch monitor for home use, the honest answer depends on your room size, budget, and whether you want full club-path data or just accurate ball flight β Grater Golf's team can walk you through that comparison directly rather than pushing a single brand.
Choosing Your Hitting Surface
The mat under your feet affects your swing feel just as much as your screen affects what you see. Whether you're after a true golf training mat for practice reps or a full golf mat built for daily simulator hitting, Grater Golf stocks options across multiple thickness and turf categories, including forgiving foam-backed mats designed to reduce joint impact on mis-hits.
For golfers who want the most realistic strike feedback, a bullseye hitting strip β sometimes listed as a bullseye 3d hitting strip β sits inside a larger mat system and gives a firmer, more ball-flight-accurate response than standard turf alone. It's a popular add-on for anyone serious about dialing in strike location, not just casual practice.
A golf ball tray for hitting mat or golf ball tray for simulator setups is a small but genuinely useful accessory too β it keeps your stance consistent shot after shot instead of reaching down or shifting position to reset the ball, which matters more than most golfers expect once you're hitting hundreds of balls a week.
Rounding Out the Room
A few finishing pieces make a simulator room feel complete rather than improvised:
-
Star Grip golf grips or other regripping options from Grater Golf's grip lineup, so the clubs you're actually swinging indoors match what's in your bag on the course
-
Mitsubishi golf shafts, for golfers building or reshafting clubs specifically for consistent indoor testing
-
A Cutwater golf bag or similar storage option to keep clubs organized bay-side instead of leaning against the wall
-
Community-driven gear from Pins and Aces, a brand Grater Golf carries for golfers who want their simulator setup to reflect their personality as much as their game
Optoma vs. BenQ: A Quick Note for Comparison Shoppers
Some golfers building a bay in the Blainville area or elsewhere search specifically for Optoma Blainville dealers when comparing brands, since Optoma is BenQ's most common head-to-head competitor in the simulator projector space. Grater Golf carries both brands, so you can compare an Optoma short-throw model against the BenQ LK935 side by side rather than relying on spec sheets alone. Generally, BenQ's laser lineup β including the LK935 β leans toward higher lumens output and finer lens-shift control, which tends to favor larger screens and rooms with imperfect ceiling geometry.
New Launch Monitors and What's Coming to Grater Golf
The simulator hardware market moves quickly, and Grater Golf regularly adds new launch monitors as manufacturers release updated models. If you're timing a purchase around a specific release, it's worth checking current golf monitors availability directly with the team before finalizing your room build, since pairing your projector purchase with your launch monitor order can sometimes simplify shipping and installation planning.
Why Buy This Projector Through Grater Golf
Ordering simulator hardware from a big-box electronics retailer means you're on your own for compatibility questions. Ordering through Grater Golf means you're working with a team that lives inside golf simulator builds every day β matching projectors to screens, mats to launch monitors, and rooms to realistic expectations. If a measurement doesn't add up or your ceiling height won't work with a given throw ratio, they'll tell you before you order, not after.
If you've already compared the specs, checked your room dimensions, and you're ready to move forward, you can buy the BenQ LK935 5500 Lumens 4K Laser Projector β Refurbished directly here on Grater Golf, with support available if you want a second set of eyes on your room layout before checkout.
Frequently Asked Questions
Is the BenQ LK935 bright enough for a room with windows or overhead lighting?
Β Yes. At 5,500 ANSI lumens, the LK935 is rated for well-lit installation environments, which makes it a strong fit for garages, basements with windows, and rooms without full blackout capability. Very bright direct sunlight will still reduce contrast, so some light control is still recommended for the best image.
What's the difference between a refurbished and a new BenQ LK935?Β
A refurbished unit has been previously used, inspected, and verified against BenQ's official specifications before resale. Grater Golf discloses cosmetic condition and included accessories directly on the listing, so buyers know exactly what they're getting at a lower price point than a new unit.
Does this projector work with any golf simulator software?Β
The LK935 is a standard 4K HDMI/HDBaseT projector, so it works with any simulator software running through a compatible PC, including E6 Connect, GSPro, and similar platforms. Compatibility depends on your computer's output, not the projector brand.
How do I know if the LK935's throw ratio will fit my room?Β
Multiply your visible screen width by the throw ratio range (1.36β2.18) to estimate the mounting distance window. For an exact answer, send Grater Golf your screen size, room depth, and ceiling height, and their team will confirm the placement before you order.
Can Grater Golf help me pair this projector with a launch monitor and hitting mat?Β
Yes. Grater Golf specializes in complete simulator builds, not just individual components. Share your room dimensions and preferred launch monitor and hitting mat, and the team can confirm the full setup works together before anything ships.
Are the projector mount and cables included with this listing?Β
No β only the items explicitly listed in the selected configuration are included. Mounts, long-run HDBaseT or HDMI cables, and simulator computers are typically ordered separately.
