4K Ultra-HD Short Throw Simulator Projector: 4000 Lumens & Dual 16:9 / 4:3 Support

The 4K Optoma 4K400STX projector features 4000 lumens and a native 16:9 UHD 3840x2160 resolution, which is perfect for any 16:9 aspect golf bays. This amazing projector is also capable of 4:3 XGA resolution for XGA golf screens, giving you total flexibility for any enclosure shape!

This high-performance laser projector easily delivers bright, beautiful Full HD images in space-constrained environments. Ideal for golf simulation. A 16:9 aspect image will pair well with golf impact screens 12 feet wide or more. 4:3 is the best fit for screens from 12 feet wide or less. The 0.5:1 short-throw lens offers massive projection images in minimal spaces, ensuring your shadow stays off the screen even with a full driver swing. It includes horizontal and vertical keystone, along with four-corner adjustment for a flexible and professional setup.

Why it’s a Game-Changer for Golf Simulation:

  • True 4K UHD Visuals: Experience every contour of the green and every blade of grass in crisp 3840 x 2160 resolution.

  • Shadow-Free Swing: The 0.5:1 Short Throw ratio allows the projector to sit just feet from the screen, keeping you, and your shadow, completely out of the light path.

  • Hybrid Aspect Ratio Support: Seamlessly switch between 16:9 (Cinematic Widescreen) and 4:3 (Traditional Square) to perfectly fit your GuardianBay™ Wedge™ Bay, InstaBay™ and more dimensions.

  • Commercial Brightness: With 4,000 ANSI Lumens, this unit cuts through ambient light, ensuring a vibrant image even in rooms with the lights on.

TurnKey Pro Tip: Powering Your 4K Experience

To unlock the full potential of this True 4K UHD display, your "engine" must match your output. Standard computers will struggle to render 8.3 million pixels in real-time, causing choppy ball flight and lag.

  • GPU Requirement: We strongly recommend an NVIDIA RTX 3070, 3080, or any 40-Series GPU (4070/4080/4090).

  • Performance: These "pro-grade" cards ensure you maintain 60+ FPS, allowing the projector to utilize its ultra-low 4.2ms input lag for a perfectly smooth swing-to-screen transition.

  • The Bottom Line: A 4K projector is only as sharp as the graphics card driving it. Without a high-end GPU, your software will downscale, and you will lose the clarity you paid for.

Check your PC specs before you buy - ensure your hardware is "4K Ready" to get the tour-level realism you deserve!

1. What is Aspect Ratio, and why does it matter?

Aspect Ratio is the relationship between the width and height of your image.

  • 4:3 Ratio: Produces a more "square" image. Best for rooms with high ceilings but limited width. To find your width, multiply your screen height by 1.25.
  • 16:9 Ratio: The standard "Widescreen" look (HDTV). Best for wider enclosures like the Guardian Bay™ Commercial size. To find your width, multiply height by 1.78.
  • 16:10 Ratio: A professional compromise often used in high-end simulators. Multiply height by 1.60.

How far away from the screen should my projector be?

Each projector has a specific throw ratio, which is an expression of image width divided by distance from the screen. For example a projector with a 0.5 throw ratio can produce a 10ft wide image from 5 feet. For Golf simulation we recommend short throw projectors with a throw ratio of 0.5 to 0.7 as they place the projector close enough to the screen so that the golfer will not block the image.

Throw distance from the screen can be calculated for other projectors using online projector throw calculators for your projector model.

How can I protect my projector from golf balls, club strikes, or other hits?

The Projector Shield from Turnkey Pro Studio is designed to do just that! Projector Shield™ Cage Isolates and Protects Your Golf Simulator Projector from Getting Hit by Golf Balls or Clubs. Check it out here:

You can find it in Frameworks under Simulator Accesories menu.

Pro Tip: For the sharpest image, always match your PC software settings (GSPro, Uneekor, etc.) to your projector's native resolution.
