Image Quality

Both the Optoma UHD35 and UHD38 support the latest in home theater technology. They can produce a true 4K resolution with 8.3 million on-screen pixels and have a high dynamic contrast ratio to further enhance that sharpness. Their color performance is strong, as well, supporting both the Rec. 709 and DCI-P3 color spectrums so you can count on the hues to be accurate and realistic.

While the image quality of the Optoma UHD35 is high, the UHD38 edges it out slightly thanks to its more powerful lamp. This gives it a more vibrant and saturated picture, even in lower light levels where the UHD35 still performs well.

As we’ve said a few times, the difference between these projectors is subtle. For most homes and viewers, the Optoma UHD35 will perform equally well to the UHD38 in both movie watching and gaming contexts. Since the UHD35 is typically priced a few hundred dollars lower than the UHD38, this makes it a better value, especially in homes where you don’t need a super-bright projector.

The Optoma UHD35 lives up to its reputation as a gaming projector. This starts with its high 240Hz refresh rate, which keeps the frame-by-frame action smooth for both games and movies. It also has an incredibly low input lag in Enhanced Gaming Mode, as low as 4.2ms at full HD and a still-low 16ms when you switch to 4K resolutions.

This is a great choice for watch TV and movies, too. The UHD35 has native true 4K resolution and a high dynamic contrast ratio for a sharp, detailed image with excellent depth and texture.

You can count on that image to be accurate to the source material thanks to the support for image technology like HDR10 and HLG. Its 8-segment color wheel produces more colors than other projectors, with UltraDetail enhancement to further optimize the image.

With a 3,600-lumen lamp, the Optoma UHD35 is relatively flexible in terms of the viewing space since you won’t need a completely dark room to use it. While it does have a long throw distance, you’ll get good installation flexibility, with both horizontal and vertical keystone correction along with manual focus and zoom controls. This makes it a great user-friendly option for multi-use spaces. For our more in-depth review of this projector click here.

The Optoma UHD38 is just as great for gaming as the UHD35 above, with the same super-low 4.2ms lag and high 240Hz refresh rate. You can play reflex-based games from the latest consoles or PC set-ups without any noticeable delay. The high contrast ratio is helpful here, too, giving more detail and depth in dark screen areas so you can see everything happening on-screen.

Since the Optoma UHD38 has a brighter lamp, it has even more placement flexibility than the UHD35. Its 4,000 lumens give a bright, saturated image even used in rooms with bright natural light, so you won’t need to worry about blackout curtains or other light control measures.
