This Better Not Be Snowbound Again

Anyone tin see the cleverness in Winston Churchill's observation that, "Golf is a game whose aim is to hit a very small ball into an ever smaller hole, with weapons singularly ill-designed for the purpose." But only the almost dedicated golfers—the ones who wish they could play even on days when they're snowbound—tin can fully appreciate the truth in information technology. Or the obsession to keep working at it. If you fall in that group, you may be 1 of many readers who take asked the states what projector to get for your in-abode golf simulator. Nosotros get the question often enough that we decided information technology was fourth dimension to provide a skilful reply.

What Counts as a Simulator?

For those who oasis't looked into simulators all the same, it volition be helpful to touch lightly on what you need for one. The offset potential surprise is that you lot don't necessarily need a projector. Carl Markestad, President of Carl's Place (www.carlofet.com)—which has focused on DIY golf game simulators for years, and has developed several bear on projection screen materials, enclosure systems, and DIY designs—points out that, although he doesn't recommend information technology, yous can display your results on a phone, tablet, or calculator monitor instead.

Of class, having to turn afterward your swing to await at a monitor off to the side is less convenient, and less natural, than looking straight ahead at an image on an touch screen—a projector screen that's likewise designed to terminate the brawl with minimal harm to the screen. For purposes of this article, I'll assume you lot've already decided to use a projector.

Edifice your ain golf game simulator means figuring out where to mount the projector and selecting the right model, but there are several important factors to consider in this decision. Shown hither is the DIY simulator installed past a customer of Carl's Identify (carlofet.com), an online resource for simulator screens, enclosures, and other components.

In addition, you lot'll demand a sensor to monitor the ball and mayhap the club, a computer to run the software that comes with the sensor and send an epitome to the projector, and some combination of an enclosure and nets to supplement the impact screen'due south job of keeping the ball from bouncing effectually the room. Details for these are outside the scope of this article, though y'all'll notice a lot of resources online. Merely it's worth mentioning that sensors are likewise known every bit analyzers or monitors, and they can employ dissimilar technologies.

At that place are lots of accessories you tin can add, from a hitting mat that volition give you the aforementioned experience as hitting a ball on an actual golf course to third-political party software that will let you lot simulate play on famous courses. But a disquisitional factor affecting your best choice of projector and where to position it will be the dimensions of the simulator space.

Where Does the Projector Go...

Markestad says the optimum size for a golf game simulator is x anxiety high, xviii-to-twenty feet deep, and either 12 feet broad for a single golfer, or xv-anxiety wide for both righties and lefties. The minimum he recommends is a 9-foot ceiling and 10-foot width and depth, although the depth will depend in office on what you're using to catch the ball. Smaller spaces are also possible, he says, but limiting. Depending on how tall you are, for instance, a lower ceiling height might non let you use your longer clubs.

Brian Gluck, President of ProjectorScreen.com—which sells both screens and projectors—mentioned another consideration for planning the space, suggesting you can use the aforementioned projector for the golf game simulator and for dwelling theater. He likewise adds that including habitation theater can be a selling bespeak for a spouse who doesn't share your passion for golf.

However, impact screens don't accept the same quality surfaces as standard projector screens even when new, and volition inevitably evidence habiliment. So for the projector to serve double duty, you'll need either a standard screen positioned to drop down in front end of the affect screen, or the standard screen on a dissimilar wall, in which example you'll demand to mountain the projector so you tin can rotate it to bespeak at the right screen.

Flooring enclosures, such as the Allsport Systems TerraShield, eliminate the demand to run signal cables and power to a ceiling mount, but their central location in front of the golfer may put them in the ball path.

Either arrangement will need a seating expanse, which can also add to the overall space yous demand. And note that Markestad takes the opposite position on a dual-purpose space, cautioning against it in part because "in practice, it's hard to make work."

...And How Does it Go In that location?

Search online for projector enclosure for golf simulators, and y'all'll find versions for both floor-mounted and ceiling mounted projectors. All the dealers I spoke to said the floor mount position in front of the hitting area is best avoided, because it tends to be in the path of the ball.

1 mentioned that some people put the projector to the side on a cart. However, another pointed out that you'll usually demand a curt throw projector (for reasons we'll embrace below), and few short throw models offer sufficient horizontal lens shift or keystone aligning to square off the picture when the projector is sufficiently far off to the side. Another choice is to mount the projector on a shelf congenital into a raised hitting expanse, merely that requires a higher ceiling for the space.

In whatever case, all the vendors I spoke to agree that the best position, and the most popular, is just behind and to a higher place the hit area. The play a joke on is to mountain information technology far enough back so you don't have to worry about hitting information technology with your golf game club, but not so far back that yous'll cast a shadow at the top of your swing.

At that place was also agreement that there'southward no real need for an enclosure when mounting the projector in that position, since the brawl is unlikely to bounce in that direction. One vendor mentioned that the only times he's ever heard of a damaged projector is when his commercial golf game simulator customers reported that someone—usually intoxicated—swung wildly and hit the projector with the club. That said, y'all may nonetheless want to consider a projector enclosure as a kind of insurance.

Beyond that, depending on how far the simulator netting and enclosure for catching the ball extends, you may be able to use a standard ceiling mountain or may need one with a special attachment that lets it connect to part of the simulator enclosure structure.

Properly placed ceiling-mounted projectors aren't likely to exist damaged by a ball or club, merely a protective enclosure like the Peerless PE1120 can provide some peace of listen.

Choosing a Projector: Throw Ratio First

The key gene for choosing a projector is finding one with the right throw ratio. The hard part is that finding the throw ratio you need is more than complicated for nigh golf simulators than for conference rooms or home theaters. By definition, the throw ratio is the distance from projector to screen divided by the width of the image. Only the throw ratio spec for whatsoever projector assumes y'all're using the full width of the native resolution, which isn't truthful for many, if not about, home golf simulators.

For a simulator, the best position for the projector will usually be roughly 4 feet behind the tee location according to Markestad, which makes the distance easy plenty to figure out. Merely the width of the simulator is a limiting factor, and the reason why you lot probably won't be using the projector'southward full prototype width.

Figuring the Throw Ratio

For the bear on screen to be high enough to accommodate the path of the ball and however fit in the typical width for a home golf simulator, it will typically air current upwards existence a four:iii aspect ratio or close plenty to it to need a iv:3 image. However a native 4:3 aspect ratio goes hand-in-hand with lower resolution than anyone would desire for a golf simulator. And so as a practical matter, you'll generally want to use a projector resolution that has a native 16:9 or 16:10 attribute ratio, and adjust the image to give yous a iv:iii aspect ratio plus letterboxing. Depending on the computer and the golf simulator software, there are a diverseness of means to brand the adjustment.

The complication is that a throw ratio based on the 4:iii letterboxed image width of a native sixteen:9 or 16:10 projector is different from the projector's spec, which is based on the native attribute ratio. So to effigy out the throw ratio you demand, you take to modify the formula for throw ratio to use the screen height instead of the width. Fortunately, that's pretty like shooting fish in a barrel.

Aspect ratio is written as width:height, which is to say,

Attribute Ratio = Width / Summit

or

Aspect Ratio X Height = Width

Substitute Aspect Ratio X Height for Width in the usual formula for throw ratio, and y'all get:

Throw Ratio = Distance / (Aspect ratio 10 Acme)

which works out to a slightly unlike formula for each aspect ratio, namely:

For xvi:ix
Throw Ratio = 0.5625 10 Distance / Pinnacle

For sixteen:ten
Throw Ratio = 0.625 X Distance / Height

With these formulas in paw, y'all tin can mensurate the distance to the impact screen and the height of the screen, and then calculate the throw ratio you lot need. Co-ordinate to Markestad, the upshot is most likely to come out in the brusque throw range or close to it, at the low terminate of the standard throw range. So while some standard throw models are potential candidates, almost aren't. Annotation that once you know the throw ratio you need, you can search for projectors by throw ratio using ProjectorCentral's Notice a Projector tool.

This DIY simulator, created by a member on golfsimulatorforum.com, is cleverly fitted to a functional garage and rolls upwards when not in utilise. (Note: image washout is due to open garage door for photography). The photo below shows the location of the three,000-lumen BenQ short throw projector on the ceiling, viii.7 anxiety dorsum from the screen and directly in a higher place the golfer where information technology does not interfere with his swing. (Run across https://golfsimulatorforum.com/forum/build-your-own/enclosures/124803-fold-upward-garage-simulator-uk for details.)

More Complications

At first glance, ultra curt throw (UST) models may seem platonic, just think again. Chris Byrne is Internet Sales Director at PSSAV (pssav.com), which has a webpage on its site specifically for golf simulator projectors. He points out that UST projectors won't piece of work with touch on screens, both because the screens lack the perfect flatness you need to avoid distortion, and because they distort further at the moment of impact. In addition, the projector would need to be so close to the screen that it volition be in the way.

Another issue is that UST models tend to be limited in how large an image—or in this instance how alpine an image—they can throw without distortion. Non so incidentally, this limitation is as well truthful for some short throw projectors, then be sure to cheque the largest image size the lens is rated for.

Billy Harrison, Production Managing director for Mainstream Video Projectors at Optoma, adds a circumspection nearly image width. Because the projector has to be mounted high enough to avoid shadows, and because most short throw projectors don't have lens shift, the projector will often need to be tilted to betoken at the screen. That means you'll need to employ keystone correction, which will narrow the paradigm.

Details on how much the image will narrow for a given degree of tilt varies with the projector. However, Harrison says that most vendors who specialize in golf game simulators are both well versed in this issue and tend to recommend merely those models that they are most familiar with, and so they know how to compensate for it. If yous're going the DIY route, be sure to enquire for advice about how to deal with this when you're picking a screen size.

Resolution

Native resolution and native attribute ratio patently go together, and the image resolution doesn't change just because you'll be using merely function of the projector's image. Just that doesn't mean a higher native resolution is always the ameliorate selection. The general consensus is that 1080p and WUXGA (1920x1200) are most popular, and near cost effective. Either one will deliver noticeably better paradigm detail than projectors with lower native resolutions. And while 4K will ameliorate image resolution further, the difference won't be as obvious as in a home theater, because the surface on affect screens isn't designed for 4K—especially afterward getting beat up by enough golf balls.

That said, I ran into a variety of views on this subject. Markestad says that 4K is not a bad idea, only not a great value for the budget witting. He also says he almost always recommends spending extra money for a laser light engine before spending for 4K. Chris Byrne adds that there are very few 4K projectors that work for golf simulators right at present in any example, since in that location aren't many that offer an appropriate throw.

Brian Gluck sees the benefit for 4K a little differently. He says the percentage difference in cost between WUXGA and 4K isn't that significant among the higher finish models. He also says that many of his customers buy a single projector for both a golf simulator and home theater. If that's true in your case, the extra cost for 4K may well be worth information technology.

Dual-purpose simulator/domicile theaters require a dedicated theater screen that typically drops into identify for movie watching or a projector on a swivel mountain that can be moved to face a second screen. This basement play space assembled by a member of golfsimulatorforum.com has a golf sim screen that hangs on hooks, and a retractable in-ceiling theater screen, assuasive both the simulator and theater to exist hidden when not in use. (See https://golfsimulatorforum.com/forum/build-your-own/enclosures/70930-creating-a-dual-dwelling-theater-golf-sim-setup for details.)

Low-cal Source

As already suggested, a laser is the preferred light source, for all the usual arguments. Most last the life of the projector, are essentially maintenance free, and offer a (slightly optimistically named) instant-on adequacy. Many likewise have a constant-brightness characteristic that adjusts automatically for the deadening aging of the low-cal source, and fifty-fifty those that don't have 1 stay brighter longer than lamps, both because of their longer life and because they lose brightness in something closer to a straight-line fashion. Lamps generally dim a lot in the get-go 500 hours, and then more slowly after that.

Of form, lamp-based projectors are perfectly acceptable choices. They nonetheless have the reward of being less expensive, and most are smaller than equivalent laser-based models, which makes them easier to handle during setup. Ultimately more than of import, most current models that are otherwise suitable for golf simulators are lamp-based.

LED projectors offering notwithstanding benefits as lasers, but no ane I spoke to knows of any current LED projectors that they can recommend for golf simulators.

Brightness

Regardless of the type of light source, effulgence requirements are essentially the same as for using any projector in ambient calorie-free. Keep in mind, however, that if y'all're using just part of a 16:9 or sixteen:x image for the golf simulator, you're using but a portion of the total lumen output. So after determining the lumen output you demand for the screen size and ambient low-cal level, you'll demand to utilise a slight correction before knowing how bright the projector needs to exist.

For a native xvi:9 projector, a 4:3 image will use 75% of the full area of a 16:9 image, reducing the low-cal output by 25%. So you lot need to multiply the brightness requirement past 1.33 to know how vivid the projector should be.

For a native sixteen:ten projector, a four:three prototype will use 83% of the projector'south area, reducing the light output by 17%, which means you lot'll need to multiply the effulgence requirement by ane.ii.

Recommended Golf Simulator Projectors

In addition to having this overview of how to choose a projector, it can be helpful to take some specific models as a kind of starter list. In keeping with Billy Harrison'due south ascertainment that most vendors who specialize in golf game simulators tend to recommend just those models that they are near familiar with, each of the sources I spoke to has their own favorites. Here's the listing of what they recommended with key specs for each. Models in the listing that don't include a lens shift spec, take no lens shift.

Lamp-Based Projectors, sixteen:9 Attribute Ratio

• BenQ TH671ST: 0.69 - 0.83 throw ratio: 1920x1080 (HD); 3,000 Lumens
• BenQ HT2150ST: 0.69 - 0.83 throw ratio; 1920x1080 (Hard disk drive); two,200 Lumens
• Epson Dwelling Cinema 1080: i.02:1 - 1.23:i Throw Ratio; 1920x1080 (HD); 3,400 Lumens

  

  Lamp-based projectors take the benefit of beingness the virtually cost-constructive option for a golf game simulator. The Epson Home Movie theater HC1080 is a 1080p projector that features 3,400 lumens of effulgence and a i.02-1.23:1 throw ratio.

• Epson Habitation Cinema 1060: 1.02:1 - 1.23:i Throw Ratio; 1920x1080; 3,100 Lumens
• Optoma EH200ST: 0.fifty:1 Throw Ratio; 1920x1080 (HD); 3,000 ANSI Lumens
• Optoma EH412ST: 0.fifty:i Throw Ratio; 1920x1080 (Hd); 4,000 Lumens
• Optoma GT1080HDR: 0.fifty:i Throw Ratio; 1920x1080 (HD); three,800 Lumens
• Optoma EH460ST: 0.50:1 Throw Ratio; 1920x1080 (HD); 4,200 Lumens
• Optoma UHD60: 1.39:1 - ii.22:ane Throw Ratio; 3840x2160 (4K UHD); 3,000 Lumens; Vertical +/-xv% Lens Shift

Laser-Based Projectors, 16:9 Aspect Ratio

• BenQ LH710: 1.13:1 - one.46:1 throw ratio; 1920x1080 (HD); 4,000 lumens

  

  Light amplification by stimulated emission of radiation projectors are preferred for golf sims for the usual reason: their long-life, maintenance free low-cal source. BenQ'south 1080p-resolution LH710 offers four,000 lumens and a i.thirteen-1.46 throw.

• BenQ LK953ST: 0.81:one - 0.88:ane Throw Ratio; 3840x2160 (4K UHD); v,000 Lumen; Horizontal +/-23% & Vertical +/-60% lens shift
• Optoma GT1090HDR: 0.50:1 Throw Ratio; 1920x1080 (HD); 4,200 Lumens
• Optoma ZH406ST: 0.50:ane Throw Ratio; 1920x1080 (HD); 4,200 ANSI Lumens

Light amplification by stimulated emission of radiation-Based projectors, sixteen:10 Aspect Ratio

• BenQ LU710: 1.xiii:1 - 1.46:1 Throw Ratio; 1920x1200 (WUXGA); 4,000 Lumens
• BenQ LU951ST: 0.81:ane - 0.88:ane Throw Ratio; 1920x1200 (WUXGA); v,000 lumens; Horizontal +/-23% & Vertical +/-threescore% Lens Shift
• Optoma ZU606TST-W: 0.79:one Throw Ratio; 1920x1200 (WUXGA); vi,000 Lumens; Vertical +21% Lens Shift

  

  Since almost golf simulators end up using only a 4:3 image, a projector with 1920x1200 (WUXGA) resolution and a xvi:10 aspect ratio has the effect of preserving a bit more than of the projector'south rated brightness for the on-screen paradigm. The Optoma ZU606ST is a 6,000-lumen, short-throw laser projector with a 0.79:one lens and adjustable vertical lens shift.

• Panasonic PT-VMZ50U: 1.09:1 - 1.77:1 Throw Ratio; 1920x1200 (WUXGA); 5,000 Lumens; Horizontal +/-20% & Vertical +44% Lens Shift

Finally, here's a list of the vendors I spoke to who recommended the projectors on the higher up list. All are skillful sources to check out for data and products when you lot're assembling the pieces for a golf simulator:

• Carl'southward Identify (carlofet.com) is a screen vendor with a special focus on DIY golf simulators. The company sells their own impact project screen materials and enclosure systems to accommodate home or commercial simulators, and offers informational resource. Carl Markestad is President of Carl's Place.
• PSSAV (pssav.com) offers a defended webpage listing a selection of projectors specifically recommended for golf simulators. Chris Byrne is Internet Sales Manager at PSSAV.
• ProjectorScreen.com, which focuses on college end projectors, offers several that it recommends for golf game simulators. Brian Gluck is President of ProjectorScreen.com.
