Optoma’s new 4K HDR projectors are aimed at gamers

Optoma UHD35/38 4K HDR projector

Optoma has unveiled two new 4K HDR home theater projectors, the $1,300 UHD35 and its slightly more powerful sibling, the $1,400 UHD38. They look like just about every other bulb-based projector on the market, but inside their plain white shells, Optoma has included some technology that will make these models a lot more appealing to gamers.

Home theater projectors do one thing really well: They provide the largest image size for the lowest price. A nice, big 150-inch image or larger is a real tempting way to play console or PC games, but the downside of these projectors is that their input lag and response times are usually too slow for serious gamers, who need things to be as fast as possible. That’s where the UHD35 and UHD38 come in.

Equipped with an Enhanced Gaming Mode, the two projectors boast an input lag as low as 4.2 milliseconds. That might not seem like a big deal when compared to dedicated gaming monitors, which can get as low as 0.7ms, but in the world of projectors, the UHD35 and UHD38 are speed demons — almost twice as quick as the previous fastest model, Optoma’s own HD39HDR .

Response times are equally impressive. If you set your game’s resolution and refresh rate at 1080p at 240Hz, the UHD3X models can turn in a blistering performance of 4.2ms. Even their slowest response rate of 16.7ms when using 4K at 60Hz is not too shabby as far as projectors go.

Those specs are going to please gamers for sure, but these projectors look to be every bit as capable for standard viewing. too. The difference between the two models as you’re no doubt wondering is brightness. The UHD35 kicks out 3,600 lumens, while the UHD38 can output 4,000 lumens. Their bulbs are rated for up to 15,000 hours of life before needing to be changed. They support both HLG and HDR10 formats of high dynamic range (HDR) material. There is also support for Rec.709 and DCI-P3 color spaces, though Optoma hasn’t said what percentage of each the projectors can display.

Optoma claims that, unlike other projectors that are labeled 4K UHD but actually have a lower native resolution, the UHD35 and 38 have a real native resolution of 3840 x 2160 — which has earned these two models a True 4K UHD certification from the Consumer Technology Association (CTA).

Image sizes can get as large as 300 inches depending on the distance from the screen. The back panel sports two HDMI 2.0 with HDCP 2.2 inputs in addition to a VGA port, a powered USB port, an optical output, an analog input and output for audio, and a 12-volt trigger port for use with motorized screens.

Though we can’t imagine anyone will want to use it, there’s also a built-in 10-watt speaker, just in case your need to game on a huge screen takes you away from your home theater setup.

What is 4K? Everything you need to know about 4K Ultra HD

High-definition content has been a TV mainstay for more than two decades now. From broadcasted cable stations to streamable movies and shows from streaming services such as Netflix and Disney+, 1080p HD is no longer the golden standard for modern TV models. It kind of feels like a no-brainer at this point, but what you want to invest in these days is a 4K TV, as most of the best TVs available are.   

4K media is also not as rare as it once was either. In fact, most new films, shows, and even video games are now engineered from the ground up with a 4K screen in mind. And not to worry if you don’t currently watch any 4K content, because most 4K TV sets do an excellent job at upscaling lower-res sources. So is it worth it to step away from your HD past in favor of a higher pixel count present and future? Let’s explore the world of 4K a little further to find the answers we seek.
What is 4K Ultra HD?
In a nutshell, 4K Ultra HD is the name assigned to a screen with a resolution that's four times that of a Full HD (1080p) TV. That translates to 8 million pixels being crammed into the same space in which a Full HD TV fits just 2 million -- achieved by making each pixel four times smaller. The result for the average viewer? A clearer image, more accurate color, and with most new TV sets, High Dynamic Range, or HDR (more on that in a bit).

The hidden costs of buying a 4K TV are way higher than you think

There’s never been a better time to buy a 4K TV. Prices have continued to drop even as screen sizes and smart TV features have continued to grow. But now that 4K TVs are priced within reach of almost anyone who wants one, are you actually going to be able to enjoy all of the extra detail and picture quality that 4K promises? The answer is, sadly, not as often as you expect, and not without some considerable extra investment over and above the cost of the TV.

Modern 4K TVs are packed with a lot of impressive technologies that can make picture quality look amazing, no matter what you’re watching. With upscaling driven by complex algorithms and often aided by AI, even watching an old DVD on a 4K TV will look way better than it did on an HDTV from 10 years ago. But to truly get the best possible results, you need access to native 4K content, preferably with some flavor of HDR, like Dolby Vision, HDR10, or HDR10+.
