Common Questions
Frequently Asked Questions
How bright is the Optoma 4K400STx and will it handle ambient light?
The 4K400STx outputs 4,000 lumens. This is bright enough for most simulator environments including rooms with moderate ambient light. Combined with true 4K UHD resolution, the image remains sharp and vivid even when total light control is not possible.
What is the throw distance for the Optoma 4K400STx?
The 4K400STx has a fixed 0.5:1 throw ratio. For a 100-inch screen, the projector sits approximately 3.6 feet from the screen. For a 120-inch screen, approximately 4.4 feet. This short throw distance lets you mount the projector close to the screen and eliminate swing shadows.
Is the Optoma 4K400STx a laser or lamp projector?
The 4K400STx uses a traditional lamp light source (240W), not a laser. Lamp life is rated at 4,000 hours in Bright mode, 10,000 hours in Eco mode, and up to 15,000 hours in Dynamic mode. Replacement lamps are available when needed. This keeps the purchase price significantly lower than comparable laser 4K projectors.
What is the input lag on the Optoma 4K400STx?
The 4K400STx has an ultra-low input lag of just 4.0ms at 1080p/240Hz. This is one of the lowest input lag figures available in any projector, making it exceptionally responsive for golf simulation and gaming.
Does the 4K400STx support HDR content?
Yes. The 4K400STx supports both HDR10 and HLG (Hybrid Log Gamma). This delivers richer contrast, brighter highlights, and deeper blacks compared to standard dynamic range content. Combined with 4K resolution and 1,000,000:1 contrast ratio, the visual quality is exceptional.
Can I ceiling-mount the Optoma 4K400STx?
Yes. The Optoma ceiling mount is compatible with the 4K400STx. You can also use four-corner keystone correction (+/-40 degrees) to perfectly align the image even with angled or off-center mounting.
How does the 4K400STx compare to the BenQ TK710STi?
Both are 4K short-throw projectors at similar price points. The 4K400STx ($2,289) has a tighter 0.5:1 throw ratio and 4,000 lumens with 4.0ms input lag. The BenQ TK710STi ($2,199) offers 3,200 ANSI lumens with a 0.69-0.83:1 throw ratio and a 20,000-hour laser light source. Both offer HDR support. The 4K400STx is better for very tight spaces; the TK710STi offers more throw flexibility with its zoom lens.
What connections does the 4K400STx have?
The 4K400STx includes 2x HDMI 2.0 (HDCP 2.2), audio 3.5mm out, S/PDIF optical audio, USB-A (5V/1.5A power), RS232 for control integration, and a 12V trigger for automated screen or light control. It is one of the most connectivity-rich projectors in its class.
Can I use the 4K400STx with any golf simulator software?
Yes. The 4K400STx connects via HDMI 2.0 and works with any simulator software including GSPro, E6 Connect, TGC 2019, Creative Golf 3D, Awesome Golf, and more. It is simply a display device -- compatible with any PC-based or console-based simulator setup.
Does the 4K400STx have a built-in speaker?
Yes, it has a built-in 10W speaker. It also includes S/PDIF optical audio output for connecting to an external sound system. For most simulator setups, an external sound system delivers a better experience, but the built-in speaker works for basic use and testing.

Customer Reviews
Overall rating: 4.7 / 5 from 81 reviews.
The mount did not attach easily to the projector that you sold with it.
Also, it is very disappointing that it takes a week, just to get the screen/enclosure into the delivery system.
Store owner replied:
Brice, thank you for the order, and sorry the mount gave you a fight.
The OCM815W is Optoma's universal mount, and universal is exactly why it does not line up out of the box. The arms sit on the circular center plate and slide and rotate independently. You loosen them, balance them out against the ZW350ST's mounting holes, then tighten them down. Any hole pattern works, but no pattern comes preset. Give us a call at (888) 871-6110 and we will walk you through it in a couple of minutes.
On the enclosure, the Carl's Place Enclosure is built to order rather than pulled off a shelf, and that build normally runs about a week before it enters the delivery system. Yours fell across the Labor Day long weekend, which added a few days. It shipped and is still on track for Friday, September 11, the date we confirmed with you when we spoke.
Thanks for trusting us with the Garmin R50 build. Call us any time as you put the room together.
Top Shelf Golf is simply the best in the business. I enjoy doing business with Ivan who is extremely knowledgeable of the newest golf equipment and he gives the best customer service.
Adding the projector and the protective cover has taken my practice setup in my garage to new level. The projector brightness is great. I don't have to swing in a dark room to see the results on the screen.
The Optoma GT2000HDR Short Throw Golf Simulator Projector does exactly as advertised! It's easy to set up and delivers more than enough light during a room-lighted golf simulator swing session. I use it daily with my iPad Pro and an HDMI to USB-C adapter. The quality is great and there is no noticeable lag! This is hands-down a no-brainer!
Working well have the project offsite from swing path keystone and corner adjustments are great. I have my in a protective cage and picture in perfect. We even watch movies and sports.
Highly recommend!!!
Plenty bright for my 8ft high 16/10 screen. Note: it was easy to set my Nvidia desktop gpu (I imagine amd and intel desktop gpu cards have this as well), through the “control panel”, to the exact 16/10 resolution of 3456x2160 then my apps, like gspro, had that as a selectable resolution.
It has great tools to adjust the shape and size of the image to perfectly adjust to fit the screen borders. I didn’t notice much (any?) impact to image quality using those image adjust features features. I tried to mount the projector perfectly so I didn’t have to use any image adjustments but decided as a short throw projector I would not be able to do that as tiny mounting changes had major image impacts.
My garage sim leaks a lot of daylight. Originally I had picked up a 3000 lumen 1080p Optoma but it just didn’t cut it. So happy I upgraded. The graphics are outstanding and the extra brightness means I can use it during the day and get a great picture. The unit does run hot, especially with the protective cover, so I added a floor fan nearby to keep the air moving. 10/10 would buy again.
Store owner replied:
Hi Stacy -
Please check out our floor mount cover for the projector, it has a built in fan. If you want to get our ProGuard cover, you won't have to use an external fan to cool down the projector.

The staff at Top Shelf Golf were great to work with they were very patient and very helpful in buying the right projector and mount to go with what i was building thank you Blake
Great experience. I had some questions about the various resolution options for this 4k projector in different image formats (primarily 4:3), and an actual human answered the phone and told me everything I needed to know. I ordered the projector and it shipped ASAP. Could not be happier with the upgrade. I went from the Optoma EH200ST to the 4k400stx. In 4:3, its about 3 times the pixel density and 30% brighter. My sim is now at 2880:2160 at 60 frames on Ultra settings in GSPRO. The difference coming from 1600:1200 is very noticeable. The throw ratios were the same, so I was able to use the current projector mount with no issues. It does take quite a gaming rig to run this. I am using a GTX 3080TI, and it works flawlessly. Guessing you could go to a slightly lower card, but not much, if you want a 4k gaming experience with a stable framerate. Would certainly by from them again.
The ZH406STx works great and is easy to setup. Support was great when I had questions and were very fast with a response. I used the side shift availability to maximize the space and it works great.
The shipping was fast.
Does the job. Wish to screen came out any more square picture. Whether on the ground or mounted to the ceiling, the edges taper down or up. Would prefer aWish the screen came out in a more square picture. Whether on the ground or mounted to the ceiling, the edges taper, down or up. Would prefer a nice square picture to fit the screen perfectly.
Store owner replied:
Hi Peter, you can either move the projector to about 5' away from the screen to cover the horizontal screen area at 4:3 aspect ratio with a smaller picture size or if you want to keep the projector where it is now, you can go to NVidia control panel and create a custom display resolution with reduced width so that the projected image doesn't violate the borders of the screen on left and right.
Great projection and works both for golf and can be hooked up to another source for movie night or sports on a giant screen! I have it hooked into an amplifier and speakers which enhances the golf and the movie capabilities! Highly recommended👍!
This is a great piece of equipment but ultimately we went with a floor protective case due to lack of ceiling height.
Thank you to everyone at Top Shelf Golf,
James Snyder
I ordered the Skytrak Perfect Bay golf simulator package, everything showed up within about a week and we couldn’t be any happier with it. The entire family enjoys playing on the system and it has really made the extra garage a new addition to the home. I’m very hopeful that this equipment can slowly help improve my game which is in serious need for improvement.
Thank you to everyone at Top Shelf Golf,
James Snyder
