Evaluation of image quality with "one knife without cutting" flagship Xiaomi TV 6 Extreme Edition

Speaking of the main force of big-screen TV products now, it must be LCD. Mature technology and affordable prices have become the first choice for most consumers to buy big-screen smart TVs. However, it is also a LCD screen, but the picture quality performance is very different. Among them, the introduction of backlight partition technology has made a new breakthrough in the picture performance of LCD TV. Now the number of backlight partitions has become a hard index to distinguish the picture quality. The more partitions, the stronger the light control ability and the better the picture performance.

In order to challenge the peak of LCD image quality, Xiaomi officially released Xiaomi TV 6 Extreme Edition and Xiaomi TV ES 2022 on June 28th. As a high-end all-around flagship, Xiaomi TV 6 Extreme Edition has performed well in the picture quality details of multiple test film sources through QLED and 100 beam splitting system. The new TV digital series released by Xiaomi this time, whether it is hardware, configuration or image quality, is fully benchmarked against international first-line brands. After two high-end flagship markets, organic light-emitting diodes and 8K, Xiaomi TV began to turn its attention to the LCD TV with the most intense competition in technology and experience.

The designed metal material highlights the texture of the whole machine.

Xiaomi TV 6 Extreme Edition is the first millet TV with all-metal integrated body. Excellent materials and technology provide excellent overall texture for the whole machine.

The front screen accounts for a high proportion, and the outer side is wrapped with an overall curved metal frame, which plays a good role in protecting the edge of the screen. There are no borders on the front screen, which minimizes the interference of design elements and brings an immersive viewing experience. Coupled with the "star screen sharp shadow" 100-level partition backlight system, this screen has achieved breakthroughs in brightness, contrast and light and dark level details.

The base is suspended and located in the center of the TV. Metal materials provide very reliable support. Compared with the design of the brackets on both sides, even the small-sized TV cabinets are placed without pressure. The thickness of 4mm gives consideration to stability and provides excellent light and thin texture.

There is also a lift camera above the screen. Xiaomi TV 6 Extreme Edition is the first TV with dual AI cameras in the industry. The camera adopts super wide-angle design and has a wider field of vision. Through setting, the camera can be lifted and controlled, and it can be turned off when it is not needed to protect the privacy of users.

Dual cameras also support AI gesture control. Even if you don't have a remote control in your hand, your fingers can complete functions such as playing pause and multi-scene video call.

Because of the full array backlight and luxurious audio configuration, the side of this product looks slightly thicker, and the material of the metal body makes the overall weight higher.

The back design of Xiaomi TV 6 Extreme Edition is also very distinctive. There is an acoustic outcrop in the middle and lower position, and you can clearly see the bass sounding unit that rhythms with the sound. The left and right sides of the back are also equipped with full-range speakers, which is more in line with the principle of sound divergence and can effectively improve the directivity of sound. The metal back plate is stamped by 1 1, and the color of space ash also gives people a calm feeling.

As the flagship product, Xiaomi TV 6 Extreme Edition certainly meets all the needs of users in terms of interface. Faster USB3.0, HDMI2. 1, network cable interface and some common interfaces are all equipped, whether it is an external USB flash drive to play photos and videos or a home host to play games.

The remote controller inherits the consistent style of Xiaomi TV, and the simple and clear design greatly reduces the learning cost of users compared with a lot of cumbersome buttons. The addition of voice buttons makes the use of interaction easier, and unsatisfied operations can be completed directly by voice commands, which is more convenient for the elderly and children at home.

Display effect: QLED+ backlight partition improves the look and feel of the picture.

First of all, let's take a look at the picture performance of Xiaomi TV 6 Extreme Edition. Xiaomi TV 6 Extreme Edition adopts 4K QLED quantum dot screen, 97% DCI-P3 wide color gamut, 103% NTSC, and 6-speed color temperature adjustment, covering various daily scenes such as sports and watching movies. 3D LUT film-level color correction technology makes the Delta E value reach 1.5, even if it is used as a display, there is no problem at all.

In terms of hardware, the screen of this product also adopts the "Star Screen Sharp Shadow" 100 level partition backlight system, which provides 1200nits brightness and 255 light control partitions, each partition can present 4096 levels of light and shade changes, giving more changes and details to the display light from the hardware level. The whole screen also supports dynamic Alpha value optimization, which improves the scene black control ability compared with ordinary LCD screens.

At present, LCD TVs equipped with QLED quantum dot display technology are not uncommon in the market, mainly high-end/flagship products. However, the number of backlight partitions used in Xiaomi TV 6 Extreme Edition is in the forefront of the industry, including 55-inch backlight partition 100 and 65/75-inch backlight partition 224/255. Take our 55-inch products as an example. At present, there are very few products on the market that can reach the number of 3-digit backlight partitions, and they are all concentrated on large-size products such as 65/75 inches.

Seeing this, many friends may have such questions. What is the impact of the number of backlight partitions? Here, I can give you a brief explanation. Backlight partition is equivalent to cutting grids with the same size in the whole picture. The brightness of these grids can be controlled independently. We can adjust the brightness to the height we need to display and turn it off completely when we don't need to display the content. In this way, the region operation can make the parts with high brightness stand out, and the places with low brightness can also achieve the effect of approaching darkness. The more grids are separated, the more natural the over-connection between regions is, and the stronger the change and contrast between light and shade are.

Specific to the scene, we can see the picture of this alternating light and dark scene, except the reflection of the middle moon and the surface texture, the rest are all black, and we can see that the surroundings of the picture are in a pure black state at this time. At the same time, the ultra-high peak brightness makes the picture information of HDR high dynamic range not lost at all, and the display of highlighted parts still has rich details, which was only available in self-luminous organic light-emitting diode products before. Now it can also be realized in LCD products through fine partition backlight adjustment.

In addition to excellent hardware support, Xiaomi TV 6 Extreme Edition also has strong technical support in image quality algorithm. The application of hardware-level AI-SR super-resolution technology can deeply analyze the picture content, match the huge image database, and optimize the low bit rate/low resolution film source to ultra-high definition level. The processed picture is not only clear, but also natural in color transition.

Xiaomi TV 6 Extreme Edition is also the first TV product in China to pass Dolby Vision IQ test. Through the dynamic metadata of Dolby Vision, we can make full use of the intelligent functions of TV, and always present better picture effects without remote control operation under different ambient light, thus achieving an experience beyond HDR.

In addition to Dolby Vision IQ, Xiaomi TV 6 Extreme Edition also supports Dolby Vision, HDR 10+, HDR 10 and HLG, achieving the current grand slam of HDR certification. In addition, Xiaomi TV 6 Extreme Edition has also obtained IMAX enhanced audio and video certification. Playing the standard film source can make the whole picture more restored and provide a better viewing experience. Xiaomi TV 6 Extreme Edition also supports Dolby panoramic sound, bringing users a more comprehensive and real audio-visual experience through Dolby Vision.

Audio experience: Support Missurround and experience the cinema viewing effect.

Xiaomi TV 6 Extreme Edition 55 inch supports Dolby Panoramic Sound 4. 1.2(65/75 inch supports 4.2.2). 55-inch built-in 13 sound generating unit, with total power of 90W, 65-inch and 75-inch built-in 16 sound generating unit, with total power of 100W, realizing super luxury sound quality experience.

Xiaomi TV 6 Extreme Edition is also Xiaomi's first TV to support Misround. Users can connect two small love speakers at the same time. The surround sound algorithm independently developed by Xiaomi can extract the "ambient sound field" from the film source and play it on the small love speaker. For example, if you put the little love speaker in the left and right directions behind the viewer, you can experience the effect of cinema viewing at home.

hardware configuration

In terms of configuration, Xiaomi TV 6 Extreme Edition is equipped with HDMI 2. 1 standard protocol interface, which supports variable refresh rate (VRR), automatic low delay mode (ALLM) and enhanced audio backhaul channel (eARC), and can provide high-standard audio and video content output. In addition, Xiaomi TV 6 Extreme Edition is the first TV in China to pass the FreeSync Premium game intelligent display certification. FreeSync Premium can make 120Hz display device realize the characteristics of no tearing, low flicker and low delay, which further ensures the experience of PC players using TV as display device. At the same time, Xiaomi TV 6 Extreme Edition is very suitable for the next generation console, and it is also the game display device officially recommended by XBOX.

Xiaomi TV 6 Extreme Edition adopts MTK 9950 image quality enhancement chip, which can decode 8K streaming video at most, and is equipped with 4.5GB storage and 64GB storage space, which supports the latest Wi-Fi 6 wireless fidelity and realizes higher speed and stable network access.

Xiaomi TV ES 2022: Lightweight flagship, quality at the same price.

Xiaomi TV ES 2022 is a lightweight flagship designed for young users. It is also equipped with a "Starscreen Sharp Shadow" partition backlight system, which supports Dolby Vision and HDR 10+ high-end HDR standards. With 4K HDR ultra-high definition panel, the peak brightness can reach 700nit, with professional display-level color standard of △E≈2, supporting10.07 billion colors, wide DCI-P3 color gamut, AI-SR super-resolution and MEMEC motion compensation algorithm, which can be called the same price for image quality.

The sound system of Xiaomi TV ES 2022 is composed of 12.5W dual-channel four-unit sound, which supports stereo playback. Each channel is equipped with low-frequency and high-frequency speakers respectively, which separates the high-frequency human voice from the low-frequency background sound and makes the sound sound more layered.

abstract

This time, the picture quality index of Xiaomi TV 6 Extreme Edition really reached the level of "slam". With the addition of QLED and 100 backlight partition, the picture display effect is greatly improved. On this basis, the hardware-level algorithm adjustment is added, and the black control effect, dark field details, character skin color, high-speed dynamic, low-bit-rate film source and other aspects are optimized. The overall performance can definitely be called a million yuan TV quality ceiling.

The dual flagship of Xiaomi TV quality officially pushed the partitioned backlight technology to the mass consumer market, and raised the TV quality to a new height. Xiaomi TV 6 Extreme Edition challenges the industry's 10,000 yuan high-end TV, bringing the first-class quality of LCD to more users; Xiaomi TV ES 2022 has improved the quality threshold of mid-to high-end TVs, and further promoted the popularization of partitioned backlight technology in mainstream price segments.
