As the fourth generation of Xiaomi TV, Xiaomi TV 4 seems to be late. As early as five years ago, its prototype was already made by Xiaomi. From the debut of the CES at the beginning of the year to the official launch in May in China, Xiaomi spent nearly half a year to solve the problem of yield, which eventually enabled it to formally enter the consumer market. For such a "late" product, its performance seems more worth the wait.
The basic parameters: 3840 × 2160 resolution / NTSC 85% / 178 ° viewing angle / Amlogic T966 quad-core / 3GB RAM / 32GB ROM / 29.2kg (with base)
Reference price: 9999 yuan (65 inches)
advantage
4.9mm slim body, beautiful appearance
Shortcomings
Dolby Panorama audio and video resources less
Edit rating: 9 points
Thickness is nearly 30% thinner than iPhone7 Plus
The back of the TV uses a whole piece of brushed metal back plate, which greatly improves the texture of the machine.
There is no doubt that the first impression Xiaomi TV 4 gives is thin. 4.9mm thickness of the fuselage, so that you can almost use "a" or "a" of such quantifiers to describe it. Because its body is so slim, we have to be very careful when assembling TVs, for fear that the TV will be deformed due to uneven force during the move. Even if the body of the millet TV 4 has been so thin, but millet seems to think it is not enough to the extreme, still in the TV frame position using a large angle of the trimming process, the thickness of the fuselage frame by both sides of the trimming contraction to 2mm ! You know that this thickness is almost as much as a dollar coin. In this way, the "visual thickness" of Xiaomi TV 4 is further reduced, and the border color of the Xiaomi TV is also designed to be a distinctive blue color that contrasts with the body, which further enhances the visual sense of the TV. It can be said that in order to achieve the ultimate slimness, Xiaomi can be said to be extremely useful.

For a TV with a price of nearly 10,000 yuan, it is definitely not enough to achieve thinness, and it should also be pursued with enough sense of refinement. Millet TV 4's frame and backplane are made of metal materials, especially a whole brushed metal back panel behind the TV, which greatly enhances the texture of the TV. However, I have some doubts about the design of the glass frame's perception of its borders, after all, the original metal texture may be more sense of grade. It is worth noting that the screws on the back of the TV and the position of the frame are a small part of the body design. If you can hide it, the whole unit will feel stronger. At the same time, I noticed that: Xiaomi TV 4 was equipped with a transparent crystal base at the CES show at the beginning of the year. Its advantage is that it can make the entire TV “floating†in the air and has a strong sense of design. However, on the official launch of Xiaomi TV 4, Xiaomi replaced the firmer metal base for stability and safety. Although it is helpless, it is somewhat regrettable.
The main speaker of this millet TV 4 has been upgraded to a larger size and has more cells
Millet TV 4 in the appearance of another bright spot is its ultra-narrow frame design, the border width is less than 5mm, to be in such a narrow frame to support a 65-inch LCD panel, the test for the process is also very high. It is worth mentioning that this time, Xiaomi made a little essay on the border design: Unlike the wraparound design used in most TV frames, Xiaomi TV 4 has a small groove between its frame and the panel. From the side, the border is even slightly behind the screen panel. The advantage of this is that, in the state of the information screen, the line of sight of the person will naturally extend from the screen to the frame, forming a visual effect of a “borderless†screen. After the bright screen, you will find that the dark side of the screen of Xiaomi TV 4 is also very well controlled, while the advantage of high screen ratio in the display is naturally also needless to say.

Millet TV 4 interface configuration is fairly rich, but the configuration of the two USB interfaces is slightly insufficient
Performance improvement is not the focus of new generation
No matter how cool the appearance is, the most important thing for the TV is still the screen, which is the quality that everyone cares most about. Millet TV 4 is equipped with a 4K panel provided by Samsung, supporting up to NTSC 85%, viewing angle of 178 degrees. Judging from the parameters, the overall quality of this panel is in line with the current flagship TV positioning. There is nothing worthy of saying more. In terms of chip performance, Xiaomi, who has always emphasized performance fever, did not make major upgrades this time. The combination of the Amlogic T966 processor and the Mali-T830 MP2 GPU is presumably familiar to many old users. In fact, this is the 65-inch version of the millet TV 3S chipset. However, Millet TV 4 has undergone a major upgrade of storage this time, and the 3GB+32GB memory configuration can meet users' needs for applications and storage.
In the backlight module, the TV can only use the edge-type backlight because it needs to maintain a slim body. Its LED light bulb is located on the edge of the screen, and the light is evenly scattered through the light guide plate onto the LCD panel. However, unlike most TV plastic light guides, Xiaomi TV 4 uses a glass light guide plate this time. Not only the light transmission effect is better, but the glass light guide plate also saves the inner frame that is the same as the fixed light guide plate, so that the thickness of the entire screen can be greatly reduced, which is also the main reason why the millet TV 4 can achieve 4.9 mm.
The performance of the color transition needs to be improved. A slight ring-shaped stain appears in the test sample.
I still test the screen quality of the Xiaomi TV 4 with a standard 4K test chart. Resolving power, this TV screen of Xiaomi TV 4 performed well. For text borders and curved lines, it was able to achieve more accurate reduction. In terms of color performance, the color of the screen is more intense and vivid. Especially in the pure black and white background, the light at the edge and center of the screen is sufficiently uniform and no light leakage occurs. However, in some scenes of color transition, the performance of this screen is slightly lacking, and the transition between the colors is not natural enough, and a slight ring-shaped stain appears. In terms of grayscale performance, this screen performed well and there was no big problem.
It can be seen that the overall picture of Xiaomi's TV 4 screen is excellent, and the details in the dark have been retained to a greater degree.
Judging from the picture quality, Xiaomi TV 4 still maintains a high level of color gamut and precise detail restoration level. The screen's layering and color performance are very appealing to the eye. However, since Xiaomi TV 4 is not equipped with a dynamic compensation algorithm, smearing may occasionally occur when demonstrating some high frame rate pictures. Taking into account that the previous generation of millet TV 3 comes standard with an independent image processing chip and dynamic compensation algorithm, it can be predicted that Xiaomi TV 4S should also join these two functions. As for the HDR function, Xiaomi TV 4 is not absent and can automatically identify the HDR source. However, it can only support manual adjustment of dynamic contrast. In the default state of “high†dynamics, sometimes the brightness is greatly increased, resulting in high light. Part of the details and colors are lost, there is a kind of overexposed look and feel. At this point you need to manually adjust the dynamic contrast in the setting options, which is troublesome. It is hoped that in the subsequent upgraded version, the TV can support automatic and real-time adjustment of the picture dynamic range.
This high color gamut screen from Xiaomi TV 4 has an advantage in displaying the richness of color
Shocking Dolby panorama sound effects
If we say that the picture quality and performance of the millet TV 4 and previous generation products to open a big gap. In terms of sound quality, Xiaomi TV 4 was regained. As an important part of the audio and video function, the sound quality of TV has always been ignored. This is mainly because the current smart TVs are getting thinner and thinner, and the TV's built-in speaker units have to be compromised. However, the split design of Xiaomi TV 4 solved this problem. The host of the Xiaomi TV 4 includes an independent acoustic system consisting of 10 units of panoramic sound channels, plus two wireless surround speakers and a subwoofer, which together form a 5.1.2 Dolby Surround home theater system.
Built-in Dolby Surround sound zone, but the current video resources are still relatively small
In terms of actual sense of hearing, the main audio unit of Xiaomi TV's 4 high-powered audio amplifiers is far better in terms of sound quality and level than the TV with built-in speakers. The best place to reflect this unique sound system is its panoramic sound performance. When you play the built-in Dolby audio movie on the TV, you can clearly feel the roar of the engine flying over the head of the engine. The bird in the forest flies over the wings and can even feel the leaves in front of it. The rustling sounds when falling down... The emergence of panoramic sound not only allows us to feel more details of the sound, but also to obtain a more three-dimensional, real sound experience. This kind of immersive experience is that you can only go to the cinema before you can feel it. The only downside is that there are still relatively few resources in the Dolby Panasonic area, and most of them are demos. There are only a few video resources. However, because Xiaomi's film and television members are cooperating with iQiyi, it also supports Dolby's audio and video resources on iQiyi's website, which can also be regarded as a remedy for resources.
In particular, the installation experience of the audio system of the Xiaomi TV 4 is very friendly. Since the main speaker has built-in power and a larger number of sounding units, it needs an independent power supply. The surround speakers are connected to the TV via a wireless connection. There is no complicated wiring and it is very convenient. It should be noted that the surround speakers need to be inserted into a receiver behind the host, occupying a USB interface, and the remaining USB interface may not be sufficient in some scenarios. However, in general, the sound quality and installation experience of this sound system are suitable for ordinary home environments.
When we were evaluating the 4T TV, we were impressed with the artificial intelligence system it was carrying. This time, Mi TV 4 also transplanted this voice system. In addition to voice recognition, Xiaomi TV 4 emphasized the interactivity of television. It can connect all the smart devices in the home. The TV plays the role of the home data hub. The core of this interactive control system is actually the artificial intelligence voice system that Xiaomi TV 4 carries. For example, you can use the remote commander to command the sweeping robot to sweep the ground, view the monitor screens of other rooms on the TV, and so on. In this way, your home has formed an IoT smart home system centered on Xiaomi TV 4. And its interaction through the voice as the core, and Google Home, Amazon Echo, Apple HomePod happens to coincide. With the huge user community advantage of the Mijia Ecological Chain, we think it has more possibilities in the future.
Summary: 55-inch version may be more cost-effective
In my opinion, like Xiaomi MIX and other products, Xiaomi TV 4 is also a product with strong concept attributes. Whether it is the appearance of the beginning or the final production, it has objectively assumed the mission of designing the “millet designâ€. It should be regarded as another great design and craftsmanship of millet in recent years. It stands behind the technical and R&D capabilities that Xiaomi has accumulated over the years.
It is also because of the "great leap forward" of millet TV 4 in terms of technology and design that it has also limited its image quality and performance. From an optional perspective, Xiaomi TV 4 should be the thinnest smart TV you can currently buy. Based on this alone, it is also enough to attract a large number of appearance association users. And if you want to consider the cost performance, in the picture quality performance is quite
