Installation Ease and Flexibility

You can use both of these projectors in either ceiling-mounted or table-top installations. They have a similarly broad range of screen sizes, too, giving them the flexibility for a variety of spaces and uses.

The Optoma UHD30 has some options for adjusting the picture, including a 1.1x zoom and a 40° vertical keystone correction. The Optoma UHD50X expands on this with more zoom (1.3x) and a lens 5-15% lens shift, which can help speed up and simplify the installation.

Picture Quality

Brightness, resolution, color, and contrast ratio all have to be considered when you’re talking about a projector’s picture quality. These two projectors are evenly matched on many of the specs, with similarly bright lamps, vibrant colors, and high contrast.

While both these projectors have native 4K resolution, the image looks slightly sharper on the Optoma UHD50X. It uses tone mapping to optimize the colors on a frame by frame basis, giving it a slight edge when it comes to the realism and clarity of the picture.

Suitability for Gamers

Gaming projectors reduce the delay between the player’s input and what you see on the screen. A good rule of thumb is to look for an input lag under 30ms for smooth, delay-free gaming. Both of these projectors can get down to 16ms, so they’re in the recommended range.

The only caveat is you’ll need to switch to 1080p HD for that super-low input lag. If you want to game in 4K, the Optoma UHD50X is the better choice. Even when you switch to 4K resolution, the input lag measures around 25ms.

Best projector for gamers: Optoma UHD50X


Here’s the one place where the Optoma UHD30 is the better option. While both these projectors are in the mid-range price point but the UHD30 typically retails for a few hundred dollars less. The difference is relatively small in the grand scheme but can be a big factor for buyers with limited budgets.

Optoma UHD30

For a 4K gaming projector, the Optoma UHD30 is an excellent value. It has an input lag as low as 16ms, as well as a high 240Hz refresh rate. You won’t experience any annoying lag, stutters, or other image issues that can impede your gameplay. We also appreciate the high contrast ratio for gaming, giving you the same clarity and detail in dark areas of the screen that you get in the brighter spots.

That high contrast ratio is great for watching movies and TV, too. The picture quality on the Optoma UHD30 is cinema-quality with vivid colors thanks to the 8-segment color wheel. Since the lamp is nice at bright, the picture quality won’t change due to ambient light in the room, either. It stays as sharp at 300” as it is at smaller sizes, too, making it a good option for outdoor movies and other large-scale applications.

You’ll get some image adjustment options with the Optoma UHD30. It does have a 1.1x zoom and a 40° vertical keystone correction for ceiling-mounted installations. The long throw distance can be a hassle in smaller spaces, but for most homes it’s a user-friendly and flexible projector for all your entertainment needs.

  • Dynamic Black technology improves contrast ratio
  • Versatile design suitable for indoor or outdoor use


  • Not as easy to install

Optoma UHD50X

Optoma UHD50X

The Optoma UHD50X has the same strengths as the UHD30 above but exceeds its performance on a number of key points. It’s easier to install, first of all. The throw distance is shorter, and it also has a tighter zoom and a vertical lens shift. That’s helpful when you need to fine-tune the image and makes installing the projector faster and less frustrating.

The picture quality on the Optoma UHD50X is slightly better, too. It uses the same basic technology, including the Dynamic Black contrast enhancement and an 8-segment color wheel. The frame rate is higher, however, and it adds UltraDetail technology to the 4K resolution to enhance the sharpness of the image. Relevant comparison: Optoma UHD35 vs. UHD50X

This higher frame rate is also good for gamers. It has the same low 16ms input lag on lower resolution settings as the Optoma UHD30. The difference is that input lag stays low when you up the picture quality, measuring at around 25ms at 4K resolution. That’s still well within the acceptable range for high-speed competitive gaming.

  • Lower input lag at 4K resolution
  • Bright lamp for a great picture in all light levels
  • Improved clarity with UltraDetail technology
  • 8-segment color wheel for vivid, accurate colors
  • Easy to install with helpful image adjustment features


  • Higher cost

What’s the Verdict?

Looking strictly at performance, the Optoma UHD50X edges out the UHD30 (>>> Check price on ProjectorScreen). Having said that, the Optoma UHD30 sells for slightly less than the UHD50X and is one of the best values in 4K gaming projectors you’ll find. If cost is a factor, you’ll be happy with the versatility and performance from the UHD30.

We hope this comparison has helped you choose the perfect projector for your home! Honestly, you can’t go wrong with either of these models, whether you’re an avid gamer or a home theater enthusiast.
