You’re not alone if you’re already comparing the new Optoma ZK521ST-B to the well-established BenQ AK700ST. These are two really great golf simulator projectors - and they’re only separated by $200. So which is the better fit for your space?

The Optoma ZK521ST-B is brighter and faster. It has a longer lifespan and a better warranty. It’s the more affordable option, too. On the other hand, the BenQ AK700ST has a shorter throw ratio with 1.2x zoom capability. It has an incredible contrast ratio as well.

Both are great, and you can find either here at Indoor Golf Outlet for the best deal online backed by exceptional customer service. Compare the Optoma ZK521ST-B vs BenQ AK700ST in depth below, or reach out for a personal consultation!

Optoma ZK521ST-B vs BenQ AK700ST (Quick Comparison)

Overview of the BenQ AK700ST

The BenQ AK700ST was purpose-built for golf simulator installations. It’s actually one of the original BenQ projectors designed from the ground up for the sim market. That shows in the impressive set of features it has. 

Why We Love It

• The deepest blacks and most vivid course detail with a 3,000,000:1 contrast ratio
• Precise image sizing thanks to 1.2x motorized optical zoom
• Works in tighter confines with its 0.69-0.83:1 throw ratio
• Supports 1080p at 240Hz with 8.4ms input lag
• Golf Mode with auto screen fit adjusts to 16:9, 16:10, 4:3, and 1:1 aspect ratios
• Single-cable connectivity from compatible PCs (USB-C input with DisplayPort Alt Mode)
• 30-bit color depth (1.07 billion colors)

Considerations

• More expensive than comparable projectors at $2,899
• Only backed by a three-year warranty
• 33.4ms input lag at native 4K/60Hz (slow compared to Optoma)
• 20,000-hour laser lifespan is underwhelming
• Pulls more power at 212W

Overview of the Optoma ZK521ST-B

We just got the Optoma ZK521ST-B added to our catalog this summer, and we’re already blown away by what it can do - and we’ve found ourselves recommending it to more and more customers lately. It’s easy to see why. 

Why We Love It

• 5,000 lumens for a super-bright display in rooms with ambient light
• 16.7ms input lag at 4K/60Hz (ultra-responsive)
• IP6X dust-sealed optical engine for peace of mind
• 15W built-in speaker
• GSPro color calibration aligns with popular golf simulator software
• 30,000-hour laser lifespan
• 5-year manufacturer warranty
• A little more affordable at only $2,699

Considerations

• 300,000:1 contrast ratio is lackluster next to BenQ’s 3,000,000:1 contrast ratio
• Fixed 0.79:1 throw ratio with no optical zoom (screen size all depends on distance)
• Doesn’t support 1080p at 240Hz
• Less of a track record since it’s only been out a few months

BenQ AK700ST vs Optoma ZK521ST-B: Side-by-Side Comparison

We don’t think there’s a bad choice between the Optoma ZK521ST-B vs BenQ AK700ST. We’ve sold countless projectors from these manufacturers and rarely encounter problems. These particular models honestly line up really closely. So, you have to look even closer if you want to spot the differences and narrow it down to the perfect pick.

Lumens and Lifespan

5,000 lumens vs 4,000 lumens - that’s the Optoma ZK521ST-B vs BenQ AK700ST brightness comparison. 1,000 lumens definitely makes a difference in rooms that aren’t completely blacked out, which is pretty hard to achieve in most home simulator setups. 

There’s also a pretty big gap in terms of lifespan - 30,000 hours vs 20,000 hours. Given the fact the Optoma ZK521ST-B is already the more affordable projector, this just tips the scale even further as far as value for the money goes.

So, advantage Optoma.

Responsiveness

The Optoma ZK521ST-B responds in 16ms at native 4K/60Hz, while the BenQ AK700ST takes twice as long. Is this a dramatic difference in practice? Not really. But it’s a difference nonetheless. 

That being said, the BenQ projector does support 240Hz at 8.4ms, while the Optoma caps at 120Hz at the same 8.4ms. In this sense, how you plan on running your projector can help you decide which is “better.”

Throw Distances

Pretty similar here. Both are perfectly viable short-throw projectors for golf simulators. But you get more margin to work with in the BenQ AK700ST. It offers a 0.69-0.83:1 throw ratio with 1.2x motorized optical zoom. 

By comparison, the Optoma ZK521ST-B locks in at a fixed 0.79:1.

So you’re getting more flexibility with BenQ. You can fine-tune the projected image without having to actually reposition the projector. Believe us, that’s a huge advantage when you’re dialing in the final image after building the enclosure. 

Golf-Specific Features

There’s a dedicated “golf mode” in each projector. 

BenQ’s version includes auto screen fit. This technology detects and adjusts to different screen aspect ratios without manual configuration. But really, the benefit for golf simulator users is the 3,000,000:1 contrast ratio. This leads to more vivid shadows, fairway contours, bunker granules, and green undulation. It really elevates the golf simulation experience. 

On the other hand, the Optoma ZK521ST-B is equipped with a GSPro calibration mode for direct color integration with probably the most popular platform for golf simulation these days. The Optoma also has IP6X protection so mat and turf particles don’t degrade performance over the years. 

Footprint and Weight

The Optoma ZK521ST-B is smaller at only 10.8 x 8.5 x 4.3 inches and 6.6 lbs. In contrast, the BenQ AK700ST is 11.94 x 9.23 x 4.43 inches at 7.48 lbs. Both fit comfortably on standard enclosure shelves, so this isn’t a make-or-break detail, really. 

Brand Support

Both sides of the Optoma ZK521ST-B vs BenQ AK700ST debate are available here at Indoor Golf Outlet, where you’ll get world-class customer service and a full manufacturer warranty:

• BenQ: 3 years
• Optoma: 5 years

The stronger coverage for Optoma reflects the longer lifespan it is rated for. But believe us when we say these are two great brands, neither of which will leave you hanging if you need help.

Price

The Optoma ZK521ST-B is $2,699. The BenQ AK700ST is $2,899. We’re only talking about a $200 price difference - but golf simulators aren’t cheap, so saving that money could be the deciding factor to some people. 

The Optoma packs tons of performance into its lower price tag, too. So it’s a compelling option. Just know that you’ll miss out on zoom, contrast, and 240Hz support. But you DO get more lumens, faster 4K response, better warranty coverage, and a longer life. 

Those are the trade-offs. Only YOU can decide which matters more.
