The Optoma UHD55 projector ($1,799), which is intended for both gaming and home entertainment, boasts 4K resolution (3,840 by 2,160 pixels), stunning color fidelity, and the minimal input lag that gamers expect. A few extra capabilities, like an Android TV that is fully integrated, are available on the rival BenQ TK700STi. However, the UHD55 triumphs in terms of image quality. It receives the greater rating of the two, while coming close to earning an Editors’ Choice pick.

DO YOU NEED A LAG MEASURE THAT IS SHORT? With a 60Hz input at both 4K and 1080p resolutions, the UHD55 has an input lag of 16.9 milliseconds as measured with a Bodnar meter. That results in a faster 4K response than the majority of projectors can achieve, putting it within the range that a hardcore gamer would deem acceptable. Even better, for 1080p/120Hz input, the lag decreased by around half, to 8.6ms. Take note that the UHD55 and TK700STi were virtually equal for first place in all three tests. The outcomes are also in line with the 4.2ms for 1080p/240Hz input specifications of both projectors, which the most dedicated gamers could choose to use.

within the.) The UHD55 leverages TI’s fast-switch pixel shifting to produce 3,840 by 2,160 pixels on the screen, as is typical for 4K DLP models, using a 1,920 by 1,080 pixel DLP chip. The UHD55 has a more conventional method compared to many more recent projectors, which often use lasers or LEDs as light sources. It makes use of an eight-segment color wheel with two sets of red, green, blue, and white panels, along with a lamp. Because they increase brightness, the white segments are frequently seen in DLP projectors made for spaces with ambient light. Additionally, they can reduce color accuracy, though Optoma has done a decent job of bucking that trend. Only in the brightest mode does the loss of color accuracy become noticeable, and even then it is less pronounced than usual.

Netflix and Amazon Prime Video are available, which is wonderful news. Hulu and YouTube, among other well-known favorites, are not. Of course, you may always insert a streaming dongle into one of the HDMI ports. Support for IFTTT (If This Then That) applets, which can, for example, automatically mute the projector when someone rings your smart doorbell, is a last clever feature.

The built-in 10-watt chamber speaker produces useable sound at a volume that may fill a sizable family room. There are S/PDIF digital output and 3.5mm analog stereo output for connecting to an external sound system.

HIGH-END HDR IMAGE QUALITY High dynamic range (HDR) color is available with the UHD55, which also supports HDR10 and HLG HDR. Aside from the three ISF modes (Day, Night, and 3D), there are ten predetermined color settings. if you want to pay someone to calibrate your room and screen on a large scale. There are two HDR10 modes, two HLG HDR modes, and six SDR input modes out of the ten specified options.

I decided to watch SDR movies and videos in Cinema mode after performing some early testing. Better shadow detail was available in game mode, although gloomy areas were overly lightened as a result. That works well in video games for swiftly identifying objects in the shadows, but it’s bad for movies because it can reduce the visual impact. If you need the projector’s maximum brightness, for instance on a bright day in a family room, you should be aware that Bright mode (the brightest) was not as green-shifted as many projectors’ brightest modes.

The shadow depth, contrast, and sense of three-dimensionality worked together to provide a properly dramatic visual impression in a dark environment. Additionally, the image was easily bright enough to be seen well in a family room with lights on at night.

The UHD55 provided a noticeable improvement in image quality for my 4K HDR tests, which isn’t true for all projectors that support HDR. For my experiments, I opted for the HDR mode rather than the WCG HDR setting. (WCG, or wide color gamut, is an abbreviation. For HLG, there are two comparable options.) Additionally, I enabled frame interpolation (FI). The function makes motion more fluid, but it also has a tendency to make 1080p recorded content resemble live footage. Contrarily, with 4K HDR, it is possible to increase contrast and three-dimensionality without the use of the digital video effect, as it was with the UHD55. In the testing, the 4K versions of the discs for the same movies I watched at 1080p SDR gave more accurate and vibrant color, and the shadow quality was improved enough to give objects in gloomy situations a noticeably more three-dimensional appearance.

The UHD55 performed a good job of not revealing rainbow artifacts, as with most Optoma models (red-green-blue flashes). Although I could plainly notice them, I hardly ever met any when using 1080p input. With 4K input, they appeared a little more regularly, but still not as frequently as with the majority of DLP projectors. However, as always, if you’re worried about seeing these artifacts, purchase from a merchant who accepts simple returns so you can see for yourself.

It was easily bright enough to illuminate my 90-inch, 1.0-gain screen sufficiently enough to be watchable even in moderate ambient light during my tests utilizing the lower-brightness Cinema mode. On an 80-inch, 1.0 gain screen in a family room with lots of windows on a bright afternoon, it was likewise pretty watchable, if a little washed out.

GOOD FOR MOVIES AS WELL AS GAMING If you like to shop on a budget, you could want to take into account 1080p projectors like the Optoma GT1080HDR and the BenQ X1300i. However, the Optoma UHD55 and the BenQ TK700STi are top choices if you’re searching for a 4K projector for gaming, home entertainment, or both.

For serious gamers, the BenQ projector offers a variety of gaming modes that quickly and conveniently adjust display and sound settings for various game kinds. That alone might be sufficient to give it the advantage for some gamers. On the other side, for watching videos and movies, both projectors had top-notch picture quality for 1080p SDR, but the UHD55 performed better for 4K HDR. For those who find rainbow artifacts annoying, the UHD55 also exhibits fewer of them, which is a huge benefit. Both are worth considering if you want 4K resolution for gaming and home entertainment, but the UHD55 should be at the top of your list.

Full HD 3D HDR10 and HLG HDR compatibility for Optoma UHD55 Pros in 4K UHD resolution sufficiently bright to fill a room with ambient light excellent out-of-the-box color accuracy minimal input lag See More Negatives One of the two HDMI ports is the only one with the low input lag. only a few streaming apps are available the conclusion Thanks to a low input lag and a high-quality image, the 4K Optoma UHD55 projector is equally suitable for gaming and home entertainment.
