Choosing the right golf simulator projector is about more than resolution, brightness, or price. You also need a projector that can create the right image size from the exact location where you can safely mount it.
In an ideal home golf simulator, I like the projector centered with the impact screen and ceiling-mounted roughly 2 to 3 feet behind the hitting position. But garages and home simulator rooms aren’t always ideal. Garage door tracks, ceiling height, attic access, launch monitors, lights, and other obstacles can force you to put the projector somewhere else.
That’s where specifications such as throw ratio, horizontal keystone correction, lens shift, zoom, and image offset become important.
In this guide, I’ll explain how golf simulator projector placement works, why throw ratio matters, and what to consider when comparing projectors such as the BenQ LK830ST and BenQ AK700ST.

What Is the Best Golf Simulator Projector Placement?
For many golf simulator rooms, my preferred projector location is:
- Ceiling mounted
- Centered horizontally with the impact screen
- Approximately 2 to 3 feet behind the ball position
- High enough to stay safely outside the swing path
There are several reasons this works so well.
1. The projector stays out of your swing
With the projector mounted above and slightly behind you, it’s unlikely that your club will come anywhere close to it during a normal swing.
That’s especially important when you’re installing an expensive 4K laser projector.
2. You’re less likely to cast a shadow
Move the projector too far behind the golfer and the projection beam may intersect with the golfer’s head or body.
The exact point where this becomes a problem depends on your room dimensions, mounting height, projector, and golfer height. But in general, keeping the projector relatively close behind the hitting area can help prevent shadows on the screen.
3. The projector is protected from most golf shots
A ceiling-mounted projector behind the golfer is also relatively well protected from direct shots.
A wild ricochet is always possible in a golf simulator, but this location generally keeps the projector away from the most likely ball paths.
4. Centering makes image setup easier
When the projector lens is properly positioned relative to the center of the screen, you’ll usually need less digital image correction.
That’s a good thing.
Features such as keystone and corner correction are useful, but getting the physical placement right first is generally preferable to relying heavily on digital corrections.
What If You Can’t Use the Ideal Projector Location?
This is where real-world golf simulator builds get interesting.
You might have:
- Garage door tracks above the hitting area
- An overhead garage door
- An attic access door
- An overhead launch monitor
- Lights or ceiling obstructions
- An unusually short room
- An offset hitting position
Any of these can prevent you from putting your golf simulator projector in the ideal spot.
Fortunately, you have several options. The first is changing how far the projector sits from the impact screen.
And to understand that, you need to understand throw ratio.
Golf Simulator Projector Throw Ratio Explained
Think about using a flashlight against a wall.
Move closer to the wall and the circle of light gets smaller. Move farther away and the light spreads across a larger area.
Projectors work on a similar basic principle, but different projector lenses produce different image sizes at the same distance.
The specification that helps you determine this is called throw ratio.
In simplified terms:
Throw Ratio = Projector Distance ÷ Image Width
A lower throw ratio generally means the projector can create a wider image from a shorter distance.
For example, if a projector you’re considering has a throw ratio of 0.65 but your room requires the projector to sit closer to the screen, you would generally look for a projector with a throw ratio below 0.65.
This is one of the most important specifications to check before buying a golf simulator projector.
Use a Projector Throw Calculator Before Buying
Don’t guess where your projector needs to go.
A projector calculator lets you enter your screen dimensions and projector model to estimate the required installation distance and other relevant measurements.
One useful resource is ProjectorCentral’s projection calculator.
If you’re specifically considering a BenQ golf simulator projector, BenQ also provides golf sim planning tools that can help visualize a simulator installation.
The important measurement is your actual projected image area, not necessarily the total outside dimensions of your enclosure.
Enter your screen dimensions, choose the projector, and see where it needs to be installed.
If that location conflicts with your hitting area, garage door, launch monitor, or another part of your room, you know you need a different throw ratio or a projector with more placement flexibility.
BenQ LK830ST: A 4K Laser Golf Simulator Projector for Tight Spaces
The BenQ LK830ST is particularly interesting for golf simulator installations where projector distance is limited.
It’s a 4K laser projector rated at 4,000 lumens with a 0.5 throw ratio.
That relatively short throw ratio means it can produce a large image while sitting closer to the screen than a projector requiring a longer throw distance.
Why laser matters in a golf simulator
One advantage of the LK830ST is its laser light source.
Traditional lamp projectors typically require more consideration around lamp life and brightness degradation. The LK830ST’s laser light source is rated for up to 20,000 hours under specified operating conditions.
For a permanent home golf simulator, that can be a significant benefit.

4,000 lumens is a useful brightness level
Brightness becomes particularly important in garages and multipurpose rooms where you don’t have complete control over ambient light.
The LK830ST is rated at 4,000 lumens.
In my simulator environment, I’ve found that this level provides a bright, usable image even when the room isn’t completely dark. Ambient light will still affect the perceived image, of course, so controlling unnecessary light around the screen can improve your results.
Contrast and dust protection
The LK830ST also offers a rated 3,000,000:1 contrast ratio and IP6X dust resistance.
Dust resistance is particularly relevant for garage golf simulators, where conditions aren’t always as clean as a dedicated indoor theater or simulator room.
BenQ LK830ST vs. BenQ AK700ST
The BenQ AK700ST is another compelling 4K laser golf simulator projector and is the model I’ve had permanently installed in my simulator.
The biggest difference isn’t simply image quality. It’s installation flexibility and convenience.
The AK700ST includes features such as:
- Auto screen fit
- Remote-controlled focus
- Zoom
- Additional installation flexibility
The LK830ST takes a more streamlined approach while offering a shorter 0.5 throw ratio that can make it particularly useful in space-constrained installations.
Why zoom matters
Zoom gives you more flexibility when determining exactly how far the projector needs to be from the screen.
Instead of having essentially one required distance for a particular image size, optical zoom can provide a range of workable mounting positions.
That can be extremely useful when you’re trying to avoid a ceiling joist, garage door track, launch monitor, light fixture, or another obstruction.
Which one should you choose?
The BenQ LK830ST makes sense if your installation requires a shorter throw and you don’t mind doing more of the initial setup manually.
The BenQ AK700ST may be worth the additional cost if you value easier setup and greater placement flexibility.
Neither is automatically the “best” golf simulator projector for every room.
The best choice is the projector that works with your specific screen dimensions, hitting position, ceiling height, mounting options, and budget.

Can You Mount a Golf Simulator Projector to the Enclosure?
Yes, depending on the enclosure.
For my test of the LK830ST, I mounted the projector directly to a Carl’s Place Pro Enclosure rather than the ceiling.
The enclosure uses 2-inch EMT pipe, making it possible to attach compatible accessories to its crossbars. I used a projector mount designed for the Pro Enclosure to hang the projector from the crossbar.
This can be useful when ceiling mounting isn’t practical, but you still need to calculate your projector position carefully.
In my test installation, for example, the LK830ST ended up slightly too close to the screen to completely fill the available image area.
That wasn’t a flaw with the projector. The setup was intentionally temporary and used to demonstrate what happens when your mounting position and throw requirements don’t perfectly match.
It’s a good example of why you should calculate projector placement before choosing your projector or enclosure dimensions.
What If the Projector Can’t Be Centered?
Sometimes moving the projector left or right is unavoidable.
Maybe you have an overhead launch monitor occupying the center position. Or perhaps your hitting strip itself needs to be offset because your room isn’t wide enough to hit comfortably from the center.
In those situations, pay close attention to horizontal keystone correction and lens shift.
Horizontal vs. vertical keystone
Vertical keystone correction compensates for image distortion when the projector is angled vertically.
Horizontal keystone correction helps when the projector is positioned or aimed off-center horizontally.
Not every projector offers both.
If you know you’ll need an offset installation, don’t assume a projector can correct for it. Check the specifications first.
The Hidden Downside of Keystone Correction
Keystone correction can solve placement problems, but it comes with a tradeoff.
It’s a digital correction.
When I initially mounted the LK830ST off-center and aimed it back toward the middle of the impact screen, the image was heavily skewed. Horizontal keystone correction could straighten it, but the usable image became significantly smaller as more correction was applied.
That’s important if you’re already trying to maximize image size.
If the projector is barely producing a large enough image before correction, aggressive keystone adjustment may prevent you from filling your screen.
Whenever possible, optimize the physical projector placement first and use digital correction for smaller adjustments.
Lens Shift Can Be Better for Offset Installations
If you expect to install your golf simulator projector away from its ideal position, lens shift is another feature worth considering.
Unlike digital keystone correction, lens shift physically changes the optical position of the projected image.
That can provide more placement flexibility without relying on the same type of digital image manipulation.
Lens shift is more commonly found on higher-end projectors, so it may increase the cost of your setup. But for a complicated simulator room, it can be valuable.
Don’t Forget Projector Image Offset
Throw ratio isn’t the only measurement you need to understand.
You also need to consider image offset.
A projector doesn’t necessarily send its image perfectly straight ahead from the center of its lens.
With the LK830ST mounted overhead in my setup, for example, the projected image begins below the level of the projector rather than directly in line with the lens.
If the natural image position doesn’t line up with your screen, you may have to tilt the projector. Tilting can then require vertical keystone correction.
This is another reason projector planning tools are so useful. They can help you understand both throw distance and image positioning before drilling holes or buying mounting hardware.
Should You Put a Golf Simulator Projector on the Floor?
Floor mounting is another option, and you’ll see golf simulator packages that use a projector enclosure placed in front of the hitting area.
Personally, this would be my least-preferred placement.
There are a few reasons.
First, you’ll probably need a very short throw distance, which limits your projector choices.
Second, you’ll have a projector enclosure sitting on the floor in front of the hitting area. Even with a protective ramp-style cover, some golfers may feel uncomfortable swinging directly over it.
You also need to deal with cables.
At minimum, you’re likely to have power and video connections running from the projector. You may be able to route those underneath putting turf, but cable management needs to be part of your plan.
Finally, a floor-mounted projector is easier to bump.
If someone kicks or moves the enclosure, even slightly, your carefully aligned image may need to be corrected again.
That’s particularly relevant if children, friends, or multiple golfers regularly use the simulator.
A ceiling-mounted projector, once properly installed, is generally much easier to leave alone.
How to Choose the Best Golf Simulator Projector for Your Room
Before buying a projector, work through these factors:
- Screen dimensions: Measure the actual visible projection area.
- Throw distance: Determine exactly where the projector can physically be installed.
- Throw ratio: Choose a projector capable of filling your screen from that distance.
- Brightness: Consider how much ambient light is present.
- Resolution: Decide whether 1080p or 4K makes sense for your budget and simulator PC.
- Light source: Laser projectors can provide long operating life and low maintenance.
- Zoom: Useful when you need flexibility in mounting distance.
- Horizontal and vertical keystone: Important when perfect alignment isn’t possible.
- Lens shift: Valuable for more demanding offset installations.
- Image offset: Make sure the natural projected image height works with your screen.
- Dust protection: Particularly useful for garage simulator installations.
- Mounting method: Decide between ceiling, enclosure, or floor mounting before purchasing.
BenQ LK830ST or AK700ST: Which Is Better for Your Simulator?
If you’re building in a tighter space, the BenQ LK830ST is a strong 4K option because its 0.5 throw ratio can produce a large image from a relatively short distance.
The BenQ AK700ST, meanwhile, offers additional setup conveniences and placement flexibility that may justify its higher price for some installations.
The decision should start with your room, not the projector.
Measure your screen. Determine where the projector can safely go. Check the throw distance and image offset. Then decide which projectors can actually work within those constraints.
That’s far better than buying an expensive golf simulator projector first and discovering later that you can’t mount it where you planned.
Final Thoughts
The biggest lesson from installing multiple golf simulator projectors is simple: projector placement and projector selection have to be planned together.
My preferred position is ceiling-mounted, centered on the impact screen, and roughly 2 to 3 feet behind the hitting position. It keeps the projector out of the swing path, minimizes shadow problems, and generally makes image alignment easier.
But that setup isn’t possible in every room.
When you need to move closer to the screen, look carefully at throw ratio. If you need to move left or right, consider horizontal keystone correction or lens shift. If mounting distance is uncertain, zoom can provide valuable flexibility.
And before buying anything, put your measurements into a projector calculator.
Whether you choose the BenQ LK830ST, BenQ AK700ST, or another golf simulator projector entirely, matching the projector to your room is ultimately what will give you the cleanest installation and best experience.
