Video Quality Of Optoma UHD51A

Optoma UHD51A is an excellent 4K UHD home entertainment projector that handles the newest innovations and technology to provide a fantastic entertainment experience for an acceptable price point, a must-have for your smart house entertainment system. Projectors have countless benefits over TVs. For setting up a home theatre, a projector lets your display be as big as the wall.


The resulting film puts even giant TVs to pity. And dimension will help you view more detail. In spite of conventional 1080p resolution, you are not going to have the ability to capture every component of a framework whilst watching an ordinary TV having an ordinary viewing space.

The reason people still venture out to movie theaters is that giant displays are immersive, and you merely need to see them to comprehend why. Some films are created specifically to be observed in theater-like ailments.

And Optoma UHD51A enjoying these pictures since they were intended to be viewed is hard to do with a fantastic projector. On the flip side, TVs are getting better than ever before. A middle-of-the-road 4K TV is going to completely loaded with half a dozen contemporary distinct performance attributes.

Performance Of Optoma UHD51A

Projector technology was lagging behind for a certain time, also leaving several customers feeling like they needed to utilize last-generation technologies to bring the cinematic experience to their houses. The Optoma UHD51A is a totally updated projector with basically every characteristic you desire. What it brings to the table is basically all the most recent and greatest developments and engineering criteria to movie quality.


Plus it has the exact same voice assistant and streaming electricity that you would find on a modern smart TV. Combined with every benefit that you use a projector to get in the first position, the Optoma UHD51A has a lot to offer. Among the numerous benefits of projectors is they are easier on the eyes.

That is represented in the 2,400-lumen rating of this Optoma UHD51A bulb. The very first thing you will notice concerning the physical apparatus is its own unassuming, professional-looking body. The projector itself is developed to 5.1 x 15.4 x 11.1-inches and weighs only just short of 12 lbs. It’s things that may ordinary influence you into choosing a TV above a projector, such as high dynamic range (HDR), 4K UHD resolution, and a wide array of vivid colors.

UHD / HDR Content

This makes the Optoma UHD51A a lot simpler to mount and handle than equal TVs, and much less difficult to put in space than any similar device. The exterior is mainly an abysmal plastic substance, but the economical of holding.

the Optoma UHD51A is not reflected in the aesthetic of this gadget. And it is certainly not reflected in its own features. Just be ready with the understanding that the UHD51A is not supposed to be dropped from 10 ft, wrapped around in the rear of a car, or built to take abuse.


Under ordinary circumstances, it utilizes closer to half that wattage, and somewhat lower compared to the power used by labs that are similar. For power-conscientious men and women, Optoma included an eco-mode, significantly reducing energy consumption largely at the expense of brightness. The eco-mode additionally creates the already-quiet UHD51A fall down to 25db, making it almost impossible to listen while playing with.

On the rear of the projector, you will find a set of HDMI 2.0 inputs. Both inputs supporting HDCP 2.2 for a complete 18Gbps rate, making the Optoma UHD51A well outfitted for 4K throughput. You will also find wires more appropriate to get 1080p content, such as a VGA-in port. Standard 3.5millimeter audio jacks are found, in addition to SDPIF for high-resolution sound.

Full HD / SDR / 3D Content

Whenever you aren’t using a remote, you’ll find that the topside controls are easy to navigate. However, what makes the simplicity of usage within the top is complete integration using Alexa Smart Home. Using the Optoma is easy due to Alexa’s intuitive voice command, along with the broad assortment of commands which you can issue without ever having to physically get into the apparatus.


You can power off and on your house theatre with your voice, adjust the volume, change resources, and also alter settings in your media player. Taking control is simple as soon as you understand all of the voice controls, and you will not ever need to worry about losing distance. The Optoma UHD51A offers native 4K HDR movie playback. After playing, you will find that Optoma’s usage of PureMotion technology smooths out the picture to get stutter-free videos.

Optoma building around DCI-P3 is great for film fanatics. If you are unfamiliar with the conventional, it is the RGB color space chosen for projecting digital pictures by the US film industry. In other words, it permits you to observe things as artists intended you to view them and as they are supposed to look in theatres.

Color Coverage

The HDR works well, particularly when you’re playing matches. There are numerous competing standards to HDR10, most especially Dolby Vision. However, for the time being, HDR10 has much more information available than some of its rivals. Beyond this, you will find more cabling and equipment being constructed for HDR10.


Comparison on projectors is hard since they rely on the area being dark. A contemporary TV can be constructed using numerous individualized brightness zones. That is how you wind up with exaggeratedly big comparison ratios, not as the 50,000 contrast ratio boasted from the Optoma UHD51A.

However, to optimize picture quality, you need to realize you will need decent theater conditions for optimum viewing. The 2,400-lumen output of the bulb means you are not going to become excellent pictures in a well-lit room.

But when you’ve got it, then you can experience 3D in its fullest scope in your home. However, the way projectors produce 3D articles is a little different from how televisions and PC monitors create 3D content. Thus, the Optoma UHD51A gives a normal 60Hz refresh rate.
The lens enables a 15% vertical change after installation, so as long as it is pointed in roughly the ideal direction.

Installation Of Optoma UHD51A

it will not be difficult to become vertical alignment between the projection and the wall socket. But you won’t find similar flat adjustability. You have to carefully align with the middle of the display during installation or you are going to encounter picture quality conditions that require more than a couple of seconds to repair.


the thing you may find missing is zoom for picture correction. The Optoma UHD51A leaves one doing manual attention instead. And yet one thing you likely will not care about will be the onboard 5-watt speakers.

Like you would expect from such tiny speakers, the audio quality is minimalistic and akin to some top excellent phone. However, these speakers are definitely intended to be utilized as a last-minute backup, rather than the main kind of functionality.

Lamp life is rated for approximately 4,000 hours when worked on total power, or nearer to 15,000 on eco-mode. That is all in line with everything you would expect from comparable projectors, and beneficial for men and women that wind up using the eco-mode frequently. And Optoma includes a two-year guarantee, which will help shield what could be a substantial investment into your house theater.

Picture Quality

The Optoma UHD51A has lots going on for it. The picture quality is near everything you would get from the top televisions on the market. Projectors often have problems producing exactly the identical comparison ratios you will receive from TVs, but the UHD51A does quite well even in areas where projectors normally do badly. Between HDR10 support as well as also the DCI-P3 color gamut, it looks great if you are doing 1080p or even 4K content.


The input lag you will find with”gaming TVs” is about 25ms, while the input of this UHDA51A is all about 41ms. When you are playing 40FPS, that translates into approximately 1.5 frames of delay. Most people will find it barely perceptible, making it a fantastic selection for many instances of exploratory gaming. But exceptionally aggressive players playing aggressive games can disagree.

For watching your favorite shows and films, the Optoma UHD51A includes all of the crucial ease-of-use kind of attributes people need from their house theatre.

It is integrated with Alexa Smart Home along with the onboard controllers are simple to use. So long as you understand where you are going to put this up, and you just take your own time with installation to stop issues with horizontal orientation, it’s easy to advocate the Optoma UHD51A. It is easy on the eyes, looks excellent, and stops you from losing a chunk of your space into a mounted TV.

A third USB is supplied to get a Wi-Fi dongle (wireless service is not built-in). There is also Ethernet, also RS-232 for the system controller, and a 12V trigger to sync with the display and AV receiver. As you may expect with this kind of projector, there is also a fundamental 2 x 5W sound system onboard, which can be helpful if you are not opting for a permanent install.


It delivers premium quality, sharp graphics, and precise color by leveraging the DLP 4K UHD processor and XPR technology. As a result of innovative picture processing and the fast switching rate of the DLP chip which provides more than 8 million pixels to the display.

The Optoma UHD51A is enjoyable to drive. It sports a snazzy, graphical interface using colored tiles that is more intuitive compared to the recognizable projector-menu text box. The experience isn’t unlike using a TV. The supplied remote controller also makes a drama at streamlining operation, though it is not backlit, and it is a disappointment.

Black Levels / Contrast

Unlike more typical PJ remotes, this includes a very simple thumbwheel layout, augmented with a couple of keys, including House, Back, and quantity controller. This choice is mimicked in addition to the projector if it is more suitable to utilize on-body controls. Physical installation is simple, using an internal test pattern generator available to sharpen everything up, along with a moderate level of vertical lens shift (+10 percent ) to align with your own screen.


Given the comparatively low asking price of this Optoma UHD51A, you should not be amazed to find that the zoom and focus controls are all manual. Optoma might have a big screen projection pat, but community operation is as slick as gravel. To trigger the projector’s clever skillset, then you will want to register and set it on Optoma’s Device Cloud Document.

The consumer experience is dreadful, requiring one to jump between programs, with Optoma within an intermediary. Alexa voice command is restricted to electricity, input, volume, and USB media player controller. Google Home controller permits you to dig a bit deeper, like selecting screen mode and activating the Optoma UHD51A image interpolation. IFTTT is somewhat different, in that it enables more seamless integration via the use of applets.

4K capacity Of Optoma UHD51A

Nevertheless, you would have to be a severe smart house winner to wish to learn IFTTT protocols. With the dubious value of clever performance apart, the Optoma UHD51A picture quality instantly gets a thumbs up. Together with both HD and UHD resources, you will find admirable levels of detail on display.

Meanwhile, the eccentric Warcraft (Sky Cinema UHD) seems strikingly naturalistic. Orcs are very fetching in 2160p. Brightness is rated at 2,400 Lumens, using a 500,000:1 lively contrast ratio.


The projector is in its quietest using the lamp brightness in Eco mode. This robs pictures of summit white snap but is not too high of a cost to be paid in a dark-room atmosphere. The operating noise is rather high, though.

The projector is HDR harmonious, and really makes a fantastic fist of high dynamic array material (given that customer projectors really can not create spectral highlights such as a TV can). The best that you can hope for from any HDR projector is considerable punch, also this particular model.

The Optoma UHD51A is just one of those very few 4K UHD boosters which deliver 3D in 1080p, which makes it a powerful contender when you’ve got a library of 3D discs. It manages 3D well, without crosstalk in my evaluations and only the normal hint of 3D-related motion artifacts.


It is possible to fix image controls in 3D style, but with all the defaults it provides an extremely watchable picture. Just like any projector, 3D is not as smart as any of those 2D manners, but the brightness falls much less in 3D compared to projectors. Unlike many Optoma versions, the Optoma UHD51A supports DLP-Link eyeglasses only.

Instead, the Optoma UHD51A did not always comprehend 3D input from Verizon FiOS. When that occurs, you need to change the video return to 2D substance, place the projector to 3D, then change the origin back to the 3D substance that you need to see. Optoma says it’s looking into this situation.

The UHD51A’s FI provides three settings apart from Off. But, there is little-to-no digital video result, which leaves nothing to gain from turning off it. Contrary to the utmost setting in several projectors, High does not smooth movement entirely, but in addition, it adds just a minor digital movie result. You may prefer a more competitive model of FI for recorded and live video, but this subtle variant is better for movies.
