Image Quality

You get 4K resolution with both projectors. With 8.3 million pixels per frame, images are amazingly crisp and clear. HDR and HGL support produce bright whites and deep blacks.

You will get a brighter picture with the UHD38, compared to the 3,400 lumens output from the UHD50X. A 4,000 lumens rating may not seem like a big difference until you watch a movie during the day. Images are brighter and crisper with the UHD38.

A home theater projector with a fast input lag and refresh rate is something every gamer needs. Either of these projectors will make gamers ecstatic, whether they’re playing GTA or Fortnite. A 240Hz ensures smooth frame-by-frame action in fast-paced games. You also get Enhanced Gaming mode with either model.

The UHD38 is the best choice for serious gamers. In gaming mode, latency speeds drop to 4.2ms. If you want to keep a 4K resolution, input lag is a fast 16ms. The UHD50X is a little slower, even when you’re in gaming mode.

Ease of Installation

You won’t have any trouble installing these projectors. Both 4K projectors are lightweight and compact. You’ll appreciate this if you are mounting the projector on the ceiling. The UHD50X is a little lighter at 8.6lbs. Throw distance is also similar. These are standard-throw projectors. If you live in a small space it will be difficult to find enough room to cast 100” pictures. You need at least 9 feet.

Digital keystone correction is standard on both components, but you’ll have an easier time installing the UHD50X. Along with a 15% vertical lens shift, you can also focus and zoom in on the images.

The UHD38 produces immersive onscreen pictures. The colors are vivid and accurate. 4K resolution, combined with a 100,000,000:1 dynamic contrast produces crisp images with sharp details. UltraDetail technology optimizes the picture, along with HDR10 and HLG support. An 8-segmented color wheel ensures colors are accurate. A 4,000 lumens light source means you don’t have to worry about ambient light.

It is a standard throw projector, and it limits where you can use it. You need around 9’ for 100” images. Horizontal and vertical keystone correction gives you a little flexibility with installation, but you are limited. Without lens shift, it takes longer to install the projector.

Gamers have everything they want in a 4K home theater projector. A fast refresh rate and low input lag ensure smooth gameplay. If you don’t want to lose image clarity in Enhanced Gaming Mode, input lag is still a low 16ms. Latency speed is fast enough to keep up with most high-action games. Add in the onboard 10-watt speakers, and you get an immersive gaming experience. For our more detailed review of the Optoma UHD38 click here.

DCI-P3 color spectrum support, UltraDetail technology, and HDR tone mapping produce stunningly realistic colors. A 3,600 lumens lamp ensures images aren’t washed out in ambient light. The light source is bright enough to handle most light, but rooms with several windows may be a problem.

Lightweight and compact, the UHD50X is also easy to install. It’s a standard throw projector, so you may want to think about a ceiling mount. With digital keystone correction, 1.3x zoom, and a 15% vertical lens shift, fining tuning images is a breeze.
