0

The Redmi Smart TV X released today can also be said to come out. As Redmi ’s first smart TV, Redmi Smart TV X offers three versions of 50-inch, 55-inch, and 65-inch. There has also been an all-round improvement, not only focusing on the surface parameters such as resolution and size but also starting to focus on image quality and performance.

This time the Redmi Smart TV X55 has been upgraded in all aspects in terms of performance and picture quality. All departments are equipped with a new Novatek (Novatek) high-end TV chip, A73 * 2 + A53 * 2 CPU architecture plus Mali G51 MP3 GPU, support for 4K decoding while also adding real-time scene recognition and optimization functions On the improvement and improvement of the picture quality performance of the entire TV.

In addition, Redmi Smart TV X also supports the MEMC motion compensation function, through chip algorithm to enhance the insertion of the real picture, eliminate the low frame rate resource when the playback is stuck, can make the display screen more smooth, for movies, animation For sports events, it is a great tool to enhance the viewing experience.

In terms of sound quality, Redmi Smart TV X also continued its efforts this time, equipped with 4 12.5W full-range, high-frequency speakers plus 4 passive low-frequency speakers, combined with Dolby sound enhancement technology, this time the TV sound effect is also a big Highlights, the sound when watching the blockbuster is shocking enough.

Other aspects, such as the design of the full screen with narrow borders, the blessing of the metal frame, the larger body memory, storage, and interaction with the rich IoT ecosystem of Xiaomi and Mijia, are all Redmi intelligence. TV X has to pay attention to the highlights, then, let us slowly experience in the detailed evaluation.

Redmi Smart TV X Design

There are three sizes of Redmi Smart TV X this time. We received a 55-inch version, Redmi Smart TV X55. Take out the body and assemble it. The narrow-frame full-screen design of the Redmi Smart TV X55 is very eye-catching. With the increase in size, the screen ratio will be further improved. Under the largest 65-inch, it is presumed that this full-screen design will be more stunning.

Close-up of the corners, you can see the extremely narrow black borders and the design of the metal outer frame. The structure of the metal frame can be seen more clearly from the back. The splicing process is used. Considering its price, it is justifiable to not use a higher-cost integrated molding. Right below the middle part of the screen, Redmi’s LOGO, a signal receiver, indicator light, and physical buttons of the switch are concentrated here.

The side close-up and the curved back design make the Redmi Smart TV X55 visually thinner than ordinary TVs of the same grade, and at the same time leave enough space for the heat dissipation of the backlight module and the driver board, without worrying about stability.

On the back, the interfaces of the Redmi Smart TV X55 are all distributed on the left side (facing the screen), the power supply is on the right side, the power adapter is built-in, and the external only needs to be connected with wires. However, the interfaces are far away from the frame, and daily installation may cause trouble.

The orientation of the rear interface is divided into two types: portrait and landscape. The horizontal interface is three HDMI 2.0 interfaces, one USB 3.0 interface, and one USB 2.0 interface. Compared with the vertically placed interface, it is easier to complete operations such as insertion. Vertically placed are the network cable socket, AV interface, S / PDIF interface, and an Antenna interface.

Close-up of the power supply, the power consumption of the Redmi Smart TV X55 is 120W. Close-up of the bracket, Redmi Smart TV X55 supports two installation methods of wall hanging and bracket. The design of the metal bracket takes into account space occupation and beautiful appearance. The included Redmi Smart TV X55 Bluetooth remote control is driven by two No. 3 batteries and is equipped with a voice button to activate the voice assistant of Xiaomi at any time.

Three, screen quality and picture quality: 85% NTSC color gamut VA screen motion compensation frame effect is obvious

Before talking about the picture quality of the Redmi Smart TV X55, let’s talk about its chip. Although many often value the panels of TVs and monitors, the role of image quality chips in the entire system is often overlooked. It can be said that the quality of the panel is the baseline of a TV, and the optimization and improvement of brightness, color, contrast and even sharpness under the blessing of the chip, and even the support of additional functions like MEMC are its best performance.

The Redmi Smart TV X55 uses Novatek’s NT7621D on the chip. From the architecture, it uses a more advanced combination of dual-core A73 + dual-core A52. The image quality algorithm is quite worth looking forward to. From the price point of view, the same size products equipped with the chip often cost more than 3,000 yuan. It can be said that the Redmi Smart TV X55 has once again achieved a “superior” price/performance ratio in terms of hardware configuration.

At least in terms of chips, this time the NT7621D on the Redmi Smart TV X55 will no longer become a controversial bottleneck as before. Next, let’s take a look at the screen quality of the Redmi Smart TV X55.

The first is the color gamut. The screen of the Redmi Smart TV X55 can achieve 100% sRGB color gamut coverage, and AdobeRGB color gamut coverage reaches 81%.

In terms of brightness and contrast, the maximum brightness of the Redmi Smart TV X55 reached 361nits in the test. Based on the results of multiple tests, the standard brightness of the screen should be 350nit. The contrast ratio of the screen is very high, reaching more than 2000: 1. Such a high contrast ratio is supposed to be a VA panel.

The magnified observation further verifies the speculation. The Redmi Smart TV X55 uses a VA panel with graded sub-pixels. Compared with the IPS panel, it will have higher contrast and darkfield performance. Darker will also have more details.

The entire screen has no dead pixels. Thanks to the advantages of the VA panel, the light leakage under the pure black display is not serious. Grayscale transition, all color blocks can be displayed, and the transition is even and natural.

It is also a test for grayscale. The levels of the bright and dark parts can reach excellent standards, the transition is uniform, the layers are clear, and there is no situation of unification.

In terms of viewing angle, all directions on the front can meet the requirements of clearly observing all the contents of the screen. The color block diagram of the color system used in the test is clearly layered, and there is no merging phenomenon.

In the 4K resolution test, the Redmi Smart TV X55’s screen itself is a true 4K panel. In the test, the details of the small characters that meet the 4K requirements can be clearly displayed.

Redmi Smart TV X55 supports dynamic contrast, local contrast, dynamic color, and other image quality optimization functions. The effect is very obvious when testing 4K pictures. After taking effect, the picture will not have the gray feeling before, and the color saturation and clarity The degree has been improved.

4K HDR video

Redmi Smart TV X55 also supports the playback of 4K HDR resources, which can enhance the dynamic range of the light and dark of the playback video, while retaining many details. However, its panel’s performance for HDR is not good (in HDR mode, the maximum brightness is only 350nit, and there is no partition backlight), so HDR can only be used as an icing dessert on the Redmi Smart TV X55 instead of the main dish.

Motion compensation is undoubtedly the biggest highlight of this time. In the previous products, this function only appeared on the super-sized flagship products. This time, it was fully decentralized to the Redmi Smart TV X55, which is a cost-effective model.

With the help of the chip’s algorithm, the Redmi Smart TV X55 can insert frames for pictures below the target frame rate (60FPS) when playing video resources. By automatically identifying the picture content, when the picture changes are consistent with short-distance movement and regularity After this condition, frame insertion will begin. After processing, the picture will become smoother, which is equivalent to the improvement of dynamic vision in general, and the observation of high-speed moving objects will be more clear.

Comparison of supplementary and non-complementary frames

For example, the most common pan-and-shift lens image in film and television is the scene that most easily triggers MEMC frame insertion. This type of video is often limited to 30 frames or 24 frames, and playing on a 60 Hz screen will have a certain sense of lag. At this time, with the blessing of MEMC, the change of fluency is obvious.

Comparing the slow motion of the frame with and without the frame

Through slow playback, you can more clearly see the effect of motion compensation. The frame rate of the picture played on the Redmi Smart TV X55 is significantly higher, and the original video picture will have a significant pause because of the insufficient frame rate.

In addition, Redmi Smart TV X55 is also very outstanding in sound. Four 12.5W speakers plus four passive low-frequency speakers perform quite well in sound. Coupled with the Dolby sound settings that come with the Redmi Smart TV X55, you can set different settings for the virtual sound and vocals. With stunning sound quality, you can customize it according to your needs.

In general, from the hardware configuration point of view, the Redmi Smart TV X55 can be described as sincere this time. The best panels and chips at the same price point, as well as good picture quality and audio specifications, use it to view film and television resources is definitely not a problem.

HDR Mode For Games

Of course, the TV is at home. In addition to watching TV programs and movies on a daily basis, there is also a relatively small demand for using TV as a screen for games.

Since you want to use it as a screen for games, you have to mention the input delay of the TV. Generally, high-end TVs can control the delay to about 20ms, but some cheaper products have not mentioned this. It will not be found until it is used, and the horror with high delay cannot be used in the game at all.

Input delay of Redmi Smart TV X55 under the wireless projection screen

Using the same screen, simply test the input delay of the Redmi Smart TV X55. In the case of a wired connection, the input delay is about 90ms, and the delay is greater under wireless projection, reaching about 150ms.

In terms of results, the 90ms wired input delay is acceptable. Like connecting a game console or a computer to play games, some non-fighting and FPS games have less stringent input delay requirements, and playing games under 90ms will not feel obvious frustration.

However, the 150ms delay of the wireless projection screen has a slightly greater impact. Considering that the current mainstream mobile games are mostly online games, there will be a wireless delay of about 50ms. If the comprehensive delay is 200ms, it will inevitably affect the game experience. Therefore, it is not recommended to use wireless projection to play mobile games on the Redmi Smart TV X55. Use PS4 to connect to the Redmi Smart TV X55 to see how it supports the game console and the picture quality.

Redmi Smart TV X User experience

When it comes to user experience, the first thing to talk about is Redmi’s optimization of various interactions on TV. Unlike mobile phones and computers, the operation of the TV is often limited to the remote control, and the small space cannot carry more buttons. This requires manufacturers to design and play the value of all buttons.

Long press the button to call the familiar setting menu

So in terms of control, many controls of the Redmi Smart TV X55 follow simple and effective logic, that is, there is a difference in the operation of tapping and long pressing. For example, taking the menu key, the short press often calls out the setting window of the current playback content, while a long press will call out the complete setting interface. After being familiar with this set of operating procedures, even if you only use one remote control, your operation will be smooth to take off.

In the modern era where the smart home concept is so popular, the control method of the Redmi Smart TV X55 is definitely not limited to this form of remote control. Redmi Smart TV X55 is equipped with the voice assistant of Xiaomi, which is also equipped with a microphone to support voice recognition, search for videos, search functions, and just move the mouth, eliminating the trouble of turning pages, entering, and searching.

Voice control can also be used to control the interface directly instead of the remote control. When voice control is activated, the entire screen will be paused, and at the same time all options will appear digital signs, with the help of digital signs can be remotely controlled in the voice.

Redmi Smart TV X55 can even be used as a home control hub. Comes with the Mijia APP, you can view the connection status of all smart homes, and also display the message pushed by the connected device in the form of a pop-up window, and display the monitoring screen in the form of picture-in-picture.

Of course, the control of the smart home has also been communicated with Xiaomi, so through voice control commands, you can give simple instructions, such as how long to perform what operation, or turn off a smart device, even more than directly in the APP Control is also convenient.

In terms of advertising, Redmi Smart TV X55 has also changed a lot. On the one hand, excellent advertisements are also valuable video content, and will not cause user rejection. On the other hand, all the advertisements of the Redmi Smart TV X55 can be skipped at the moment. This is not a strong buy and sell. All it does is push excellent content to users.
