Optoma UHD38 4K Projector Review

One minute review

The Optoma UHD38 is a slightly more compact DLP4K projector that is more suitable for all-time use at home but has special features for gaming. The UHD38 is equipped with 4,000 ANSI lumens that can be used during the day as it is capable of pumping very bright reflections.

However, its real effect is the ‘enhanced game mode’, which reduces input latency and has a response time of 16.7ms, which can be played with console and computer games 4K / 60Hz, and even faster than 1080 / 120Hz if you bother. Mm. A drop in detail.

Yes, you can find even faster specifications on LCD monitors, but not on really high-end models of most projectors or TVs. Unable to compete with smaller monitors, the UHD38 offers super-sized images with crisp, vibrant HDR color and often great contrast. It also offers the 32: 9 ‘ultraviolet’ aspect ratio that some sports now offer.

Following in the footsteps of the Optoma UHD30, the UHD38 is a superior omnipresent projector, but not for everyone. why not? It will be its long throw lens. It has the ability to create a 300-inch image, requiring it to be used for a very high-end gaming game if it has a large blank wall. If you put 3 meters of UHD38 at the put, know that this long throw lens will reduce the size of the image to about 100 inches somewhere.

Optoma UHD38 Bright, True 4K UHD Gaming Projector


Optoma UHD38 is at the forefront of Optoma’s powerful DLP projector series for 2021. The key difference between Optoma UHD 38 and Optoma UHD 35 steps, the successor to Optoma UHD 30 from 2020, is brightness. The first manages 4,000 ANSI lumens and the second ANSI collects 3,600 lumens. Both include a very important ‘enhanced game system’ that makes it faster than most TVs, and (theoretically) gives the user a slightly more competitive gaming advantage.

  • Designs and features
  • The 10x speaker features 2x
  • Long throw rate
  • The airflow grill leaks light

UHD38 is reasonably compact and measures 315 x 270 x 118 mm. (12.4 x 10.63 x 4.65 inches) and weighs 3.98 kg (8.77 lb). Easy to access and position, the round white plastic chassis is nice with a few light-leaking airflow grills. If you are sitting in front of an UHD38 that you can do most of the time, you will not see it – even in a dark room, if there is a glowing blue light in your eye line as a result, it will distract you.

Setting is simple if there is no flexibility. There is a manual focusing ring around the lens and a rear lever that offers 1.1x magnification. Critically, since the UHD38 has a throw ratio of 1.5: 1, you should place it about 100 meters from a 100-inch screen. It also does not have the manual lens switching lever that should be included in all projectors at all times; Providing some basic digital key correction controls is not a substitute.

The back has an HDMI 2.0 input bracket. However, UHD38 buyers may be interested in its ‘enhanced game system’, but its lack of HDMI 2.1 suggests that it may not support 4K / 120Hz. There are many more interiors; A trigger for connecting a screen with VGA, 3.5mm audio and beyond, optical audio, USB-A and a 12V prototype motor.

Its other main feature is that it has brighter than ever. At 4,000 ANSI lumens, UHD38 is significantly brighter than its bearing UHD30, delivering 3,400 ANSI lumens. That means it can work during the day, but if you have enough screen or wall, you can push those images over 100 inches.

That extra brightness does not seem to diminish the life of the extracted lamp, and Optoma promised 15,000 hours of brightness for UHD 30 as well as 4,000 hours and 10,000 eco-friendly.

The UHD38 is also equipped with a 10W speaker, which gives it considerable quality in its small size. It can be slightly noisy but it reaches high volumes without distortion. The box also has a small, slightly remote control, however the blue light is useful when in use. Sometimes it takes multiple printers to get commands to work, but it is not as responsive as possible.


  • The enhanced gaming system works well
  • The film manages to entertain as well as inform
  • Not as flexible as some projectors

Here is a projector that has been optimized for gaming but is still generally impressive. The UHD38’s flagship feature – enhanced gaming mode – impresses with its latency, but not the maximum with 4K. In fact, if you play a 4K / 60Hz game domestically, UHD38 offers only 16ms response time (still faster than most TVs) and does not support 4K / 120Hz. At 1080p / 120Hz it manages 8.9ms and at 1080p / 240Hz another 4.2mm. These features use any presets such as gaming, reference and brightness from the movie.

This is a description of many things that do not get the attention of most people; A low UHD38 of less than 40ms is enough to attract attention.

Most importantly, the fast-paced action sequence of games and movies is not adequately invisible, the camera jars do not suffer from decency and there is no trace of that old DLP – the ‘rainbow effect’. In fact, UHD38 gives the desired image regardless of source and resolution.

When it shows 4K, you see an image less than 8.3 megapixels. The pictures are crisp, subtly detailed and sink in too much. The eight-part DLP color wheel on the UHD38 is color-coded and well-saturated – albeit large enough to actually generate colorful games – and we’ve seen more powerful HDR and better black levels. The gaming mode adds extra brilliance to the game and will convince you to watch 4K Blu-ray movies in movie mode.

If you want it to be very bright, its bright NSI Lumen 4,000 is ideal for use in summer afternoons, hosting projection as long as there is no sunlight on the screen. However, the bright mode adds a significant amount of green.

The UHD38 is not the most flexible projector for the home – for its high quality in all respects – save for the average black levels. The charge is square with its long-throw lens, its 1.5: 1 throw ratio and the small size of 1.1 magnification means that you are trying to project an image smaller than 100 inches.

For all its quality, be aware that the UHD38 native 4K projector does not speak strictly. The DMD DLP chip, built around 0.47 Texas devices, is optimized for 1080p, but uses pixel switching technology to create an image of multitasking flash, which always looks like an important 3840×2160 pixel-4K resolution. However, you will struggle to tell the difference.

If so, buy it …

All you need is a day and night epic game

Like the day or night gaming game, UHD38 can produce a massive image size as large as 300 inches, thanks to its 4,000 luminous output of 4,000 lumens.

You want to get the best out of your next generation console

All enhanced gaming modes that work with 4K / 60Hz, 1080p / 120Hz and 1080p / 240Hz consoles or computers and ensure that input delays are not a problem.
