Now, Xiaomi has brought two brand new 82-inch Master Edition large-screen TVs-Mi TV Master 82-inch and Xiaomi TV Master 82-inch Supreme Commemorative Edition. The latter is equipped with an 8K resolution Mini LED screen, which is also Xiaomi’s first 8K TV.
It took Xiaomi seven years to walk through the exploration process of LCD TVs, quantum dot TVs, OLED TVs, transparent TVs, and Mini LED TVs. It can also be seen that Xiaomi TVs have been continuously climbing on the display technology ladder. To the ceiling of display technology.
It is worth mentioning that the 82-inch Supreme Commemorative Edition of Mi TV Master supports 5G communication. After all, under the premise of rapid commercial use of 5G networks, 8K TV has ushered in a hot year. At the same time, 5G+8K is hailed as the benchmark flagship configuration of current color TVs. In 2020, it has become the main battlefield for 8K TVs.
It just so happened that Kuai Technology received an invitation letter from Xiaomi TV not long ago, and opened the fire seal. The invitation letter said “What kind of TV do we need in the next five years? All the answers are in the one you are about to see. Among the products.” “Integrating many cross-age black technologies in one, coming from the imagination of the next generation, Xiaomi TV Master Extreme Commemorative Edition, we sincerely invite you to witness together. Such a high positioning is quite attractive, so we immediately rushed to the tasting, and then we will experience the two new 82-inch master TVs from Xiaomi.
Mi TV Master DesignThe Mi TV Master 82-inch is a relatively traditional LCD screen TV. It uses an 82-inch 4K screen with a resolution of 3840*2160, a 178° viewing angle, a DCI-P3 93% wide color gamut coverage, and 120Hz. Refresh rate, 10bit panel, can display 1.07 billion colors.
Since it uses LCD material screen (it is reported that the screen supplier is LG Display), it naturally has a backlight system, with 240 light control zones, 1000nits brightness, 140000:1 contrast ratio, brightness uniformity of 90%, and each zone can be displayed 4096 levels of light and dark changes.
How big is an 82-inch TV? We sent a colleague who was more than 180cm tall to hug the TV screen. His arms span couldn’t touch the sides of the TV at all, so we could get a glimpse of the size of the TV.
The physical front frame obstructing area on the four sides of the TV is not too large. It is worth noting that the all-metal wire drawing process appears on the edge, which creates a sense of quality.
Due to the existence of the backlight module, the 82-inch Mi TV Master is naturally not thin and light. A simple comparison shows that the width of the TV is almost the same as the width of the TV remote control. For the pursuit of a thin and light appearance, the 65-inch version of the Mi TV Master, which has previously adopted an OLED screen, is recommended. This is the Mi TV with the strongest sense of unity on the back that I have ever seen.
Unlike the glass base of the 65-inch version of the Xiaomi Mi TV Master, the Mi TV Master 82-inch has returned to the traditional TV base, obviously emphasizing more practical meaning. Looking at the interface configuration, 3 HDMI 2.1 ports + 1 AV port + 1 ATV/DTMB port + 2 USB 2.0 ports + 1 Ethernet port, which is exactly the same as the previous Mi TV Master 65-inch version. And the HDMI 2.1 standard protocol interface supports 4K 120Hz image quality input. This is a Bluetooth voice remote control, returning to the traditional plastic material, the overall button layout and the interaction logic used have not changed.
Mi TV Master Appearance
The appearance of the Mi TV Master 82-inch Supreme Commemorative Edition is compared with the 82-inch Mi TV Master just seen. Apart from the same size, it is almost different in other aspects. The most obvious is the 8K physical resolution of 7680*4320, which is four times that of 4K and 16 times that of 2K. It is extremely clear even when viewed at close range.
It supports up to 8K 120Hz MEMC ultra-high-speed motion compensation, intelligent restoration of low frame rate video to 120Hz per second, the backlight system has 15,360 Mini LED lamp beads, 960 light control zones, controlled by 60 independent light control chips, each The partition can show 4096 levels of light and dark changes.
This is also an exploratory exploration. The Mi TV Master 82-inch Supreme Commemorative Edition brings one of the most advanced displays technologies-Mini LED. Mini LED display has better color rendering and high contrast effect comparable to OLED self-luminous.
In principle, the thickness of the Mini LED display can be close to that of the OLED display, and it also has special-shaped cutting characteristics. With a flexible substrate, it can even achieve a high-curved backlight. However, due to various factors such as the existence of the backlight module and its large size, the thickness of the Mi TV Master 82-inch Supreme Commemorative Edition is still not as amazing as the 65-inch Mi TV Master, but it is better than many quantum dot screen TVs we have experienced before.
The processing of the edges of the Mi TV Master 82-inch Supreme Commemorative Edition is similar to the 82-inch Mi TV Master just seen. It uses the all-metal wire drawing process. The difference is that the former has a one-piece bending process, and the sense of borderlessness is stronger.
The two gray areas of “dominant side leakage” that extend beyond the two sides of the TV screen are actually the “Sound Wings” automatic telescopic sound system. In simple terms, it can be understood as two independent soundbars with 8 units. Three-way frequency inverted bass enhancement system, bi-amp electronic crossover, 20 watts bass*2, mid-to-high frequency 10 watts*2 hardware configuration.
The reason why it is designed like this is not to gain eyeballs. According to Xiaomi’s official statement, the overall audio and video center can be achieved in the center of the screen, achieving the effect of “audio and video on the same screen”. The base of the Mi TV Master 82-inch Extreme Commemorative Edition supports rotation, and with the viewing angle of 178°, it realizes a more flexible viewing mode under the condition that large-size TVs are not easy to move.
As the highest specification Xiaomi TV today, the interface of the Mi TV Master 82-inch Extreme Commemorative Edition is very generous-1 HDMI2.1 interface + 2 HDMI 2.0 interfaces + 1 AV port + 1 ATV/DTMB interface + 2 One USB 3.0 interface + 1 Gigabit Ethernet port + 1 S/PDIF.
The HDMI 2.1 standard protocol interface supports up to 8K 60Hz image quality input and ALLM automatic low-latency mode, which is in line with the next generation of game console standards. Standard metal NFC remote control, support one-touch screen projection
178° viewing angle
We first conduct the “4K resolution test chart” test. This test tool is based on the principle of TV image quality display and is customized for 4K TVs in all directions. It is made by experts in the field-a member of the Chinese Photographers Association and National Photographic Machinery Standardization Produced by Mr. Qian Yuankai, a member of the Technical Committee.
The above is the overall test tool. The three pictures test the TV picture from the three aspects of clarity, color accuracy, and wide viewing angle. The test picture has red and blue arrows, blue is 1080P, red is 4K. Next, we can ignore the blue arrow in our test process to see if the Mi TV Master 82 inches meets the test requirements for image text annotation.
We follow the process to test the clarity first. Looking at the screenshot, you can see that all the four lines of Chinese characters and letters in the picture can be clearly identified and displayed, and the effect is also clearly visible. Generally, display devices with poor performance will lose the text details in the small Chinese characters/letters in this test. The Mi TV Master 82 inches passed the test.
This is a color image test. Observing the color distribution chart and chromosphere chart on the screen, you can find that the color block saturation of the test result is better, and there is no step or parallel that is easy to occur in some devices before, which can display the level. Rich colors.
In the color distribution diagram, the 82-inch display effect of the Mi TV Master meets the text labeling requirements, and the color distribution areas such as R, G, B, Y, C, and M accurately present the ideal shape. The color sphere diagram is also better, which shows the overall color Even and soft transition.
Look at the viewing angle test. In this test project, the Mi TV Master’s 82-inch 178° viewing angle meets the needs of users. For multi-family members or large-sized households, viewing from various angles is not observable. The shadow experience has a significant impact. We also conducted a grayscale test on the 82-inch Mi TV Master. Looking at the details, each level of grayscale can be distinguished without stepping.
Hardware & Performance
Same as the 65-inch Xiaomi Mi TV Master, the Mi TV Master 82-inch is also equipped with the MTK 9650 high-end TV chip. This core has not been released by MediaTek before, and it should be a new core customized by MediaTek for Xiaomi.
According to the official information provided by Xiaomi, we can know that MTK 9650 adopts a 22nm process, quad-core A73 CPU architecture + Mali G52 MC1 GPU architecture + 1T computing power APU. For detailed analysis, please refer to our previous evaluation of the 65-inch Mi TV Master.
During the live experience, we found that based on the MTK 9650 platform, 4K 120Hz video can be decoded and played smoothly, but there is nothing for 8K video.
The Xiaomi Mi TV Master uses an 82-inch 4K Ultra HD screen with a resolution of 3840*2160, a 178° viewing angle, a DCI-P3 93% wide color gamut coverage, a 120Hz refresh rate, a 10bit panel, 1.07 billion colors, and The integrated backlight system has 240 light control zones.
According to the official statement, the Xiaomi Mi TV Master 82-inch has 1000nits brightness, a 140000:1 contrast ratio, and brightness uniformity of 90%. It supports Dolby Vision, HDR10+, HDR10, and HLG. We use the Starscream color calibration instrument to test the brightness, contrast, and color gamut.
Due to multiple reasons such as engineering prototype, instrument accuracy, software version, etc., the test results will have a certain range of errors with the real parameters.
Mi TV Master Experience
“OLED TVs will be withdrawn within ten years.” “Like plasma TVs that were a smash hit back then, they still withdrew from the market. Because OLED panels do not conform to optical principles, they may also be withdrawn within 10 years, especially for OLED TVs with such medium and large-size OLED panels. , Will bear the brunt.”-Innolux Ding Jinglong
Mini LED pump manufacturers such as Innolux have made the sound of “bad” OLED as early as last year. Most of these opinions think that mobile phone OLED panels are currently hot and there is not much pressure to exit in a short period of time, but The price of OLED TV panels is inflated, and it is expected to be replaced by Mini LED panels with lower cost and similar or better picture quality.
Of course, we don’t have to care too much about these “crazy words” of the pioneer manufacturers of Mini LED panels. From another point of view, OLED panel technology currently falls among a few manufacturers, and it is even more difficult to intervene. Mini LED may also be an attempt by some manufacturers to open up new areas and reorganize new orders.
What’s more, there are many new panel technologies emerging in an endless stream. OLED and QLEDMicroLEDMini LED each claim that they are the future and they are the masters. The situation is still unclear. We don’t need to get involved in this kind of debate for the time being.
Its significance is no less than transparent TV
Mini LED itself is not mysterious, as the name suggests is a miniaturized LED system, it also has a backlight module, which is an upgrade of the LED backlight. The usual LED light bar is one, which mainly uses the light guide plate to spread the brightness, while the Mini LED backlight achieves a large number of ultra-small LED light groups to achieve the backlight effect. Take the Mi TV Master 82-inch Extreme Commemorative Edition as an example, its backlight system uses a total of 15,360 Mini LED lamp beads.
In this way, although the Mini LED backlight system still belongs to the principle structure of LCD, compared with traditional LED TVs, the number of dimming partitions can be made more detailed to achieve high dynamic range (HDR) and high contrast effects. The improvement also has a greater effect, especially better dimming can effectively improve the color gamut performance, and can also shorten the optical distance to reduce the thickness of the whole machine to achieve thinner requirements.
Of course, Mini LED TVs are not perfect. More ultra-small LED lamp beads will inevitably consume more energy, and the power consumption of the same peak brightness may be higher; more detailed partitions will affect the backlight driver board and software of the TV. The light control algorithm requirements are relatively high.
As a result, certain thresholds have caused no other manufacturer to test Mini LED TVs and launch corresponding products except TCL. At this level, the exploratory significance of the 82-inch Supreme Commemorative Edition of Mi TV Masters for the industry is not inferior to that of the previous transparent TVs-opening up the road for latecomers and educating the market.
The Mi TV Master 82-inch Supreme Commemorative Edition uses a 10bit panel, supports 1.07 billion primary colors, and achieves a wide color gamut coverage, with DCI-P3 reaching 98%. The customized independent APU neural network computing unit can intelligently analyze, identify, and optimize the picture.
Xiaomi is worth mentioning that HDR dynamic reshaping will show the ideal value of depth, detail, brightness, contrast, and wide color gamut for every scene and every frame of the video.
About Novatek72685 8K TV chi
Many people are relatively unfamiliar with the Novatek 72685 8K TV chip in the Mi TV Master 82-inch Supreme Commemorative Edition and the manufacturer behind it.
Let’s talk about Novatek. This is a very low-key manufacturer in the industry. Regardless of the Internet in Chinese and English, there is little information about it. At the beginning of its establishment, it mainly focused on computer peripheral chips, and then its focus turned to LCD driver ICs and system single chips.
Xiaomi was once the top ten IC design company in the world in terms of revenue in 2015. The market share of the display driver IC field was once the world’s largest at that time, and the launch of TV chips was also easy.
The information about Novatek 72685 8K TV chip is as mysterious as this manufacturer. At present, it can only be known that it uses dual-core A73+ dual-core A53 high-performance CPU, Mali G51 MP4 quad-core GPU, and even supports 5G communication. It is a more typical flagship chip.
This makes the Xiaomi Mi TV Master 82-inch Supreme Commemorative Edition the world’s first 5G mass-produced TV that has passed the CTA network access certification test. It supports 5G SA and NSA dual networking, covering the three major domestic operators, and the SA network theoretical download speed is as high as 2.1Gbps.
Let’s first use a computer to try the video’s stress on the hardware. AMD Ryzen 7 1700X 8-core 16-thread soft solution, some overwhelming, the CPU occupancy rate is 40-100%, which is relatively slow. Although hard decoding is not stuck, the GPU occupancy rate has reached 60-80%, and the CPU occupancy rate is still 40-90%.
AMD Ryzen 7 1700X 8-core 16-thread soft solution, CPU occupancy rate 40-100%, slightly card. Even for the PC host platform, the load pressure is very high when facing 8K video, and the pressure on the TV chip is even more predictable. Next, we will use this video to play on the Novatek72685 platform of the Mi TV Master 82-inch Supreme Commemorative Edition. It can play 8K videos for a long time without any pressure and is quite smooth.
About sound and picture
In the hands-on experience part, we saw that the Xiaomi Mi TV Master 82-inch Extreme Commemorative Edition is equipped with 2 independent soundbars, an 8-unit three-way inverted bass enhancement system, bi-amp electronic crossover, 20 watts of bass* 2. Hardware configuration of medium and high-frequency 10W*2.
Specifically, the 8-unit full-band speakers are divided into high frequency*2, mid frequency*2, and low frequency*4. The three types of speakers cooperate with each other to complete the high, middle, and low-frequency bands. Among them, the 2*2.5L super-large cavity brings powerful dynamic low-frequency effects, but it should be noted that do not place the TV in areas such as hollow wooden cabinets. After resonance, it is easy to produce broken sound and affect the experience.
It is worth mentioning that the Xiaomi Mi TV Master 82-inch Extreme Edition also supports Dolby Vision and Dolby Atmos 2.0, compatible with all Dolby formats (including 5.1, 7.1), and supports Dolby DigitalPlus & DTS-HD audio decoding.
Content and boot ads
Let me talk about 8K content first. At present, Samsung, LG, TCL, Skyworth, Hisense, Changhong, Konka, Haier, etc. have all launched 8K TV products, but at the same time, the 8K ecology is extremely lacking. Xiaomi, which is known for its content, is expected to bring something different. Variety.
According to Xiaomi’s official statement, its in-depth cooperation with iQiyi to launch 8K channels supports 50 8K ultra-high-definition blockbusters for online viewing. At the same time, it is equipped with SR image enhancement technology, which can present low-resolution content with high-quality, realizing the full 8K content in the true sense. However, the channel has not yet been launched when we experienced it, and we look forward to officially opening it soon.
Regarding the boot advertisement, because of the early engineering machine system used in the Mi TV Master 82-inch Extreme Commemorative Edition we have experienced, there is indeed a boot advertisement. Whether the official version still has a boot advertisement is currently unclear.
About the system
MIUI on Xiaomi mobile phones has become the leader of the domestic OS, and MIUI for TV, which has been running for seven years, is also excellent, leading the growth of Internet TV operating systems. The homepage structure of the previous generation of MIUI for TV was a mixed layout: input source + tools + application + recommendation, and the layout was exquisite, which satisfies the user’s habit of watching “TV stations” at that time.
But for users who basically only watch online videos, it still seems too complicated, so this generation has obviously thought about it and made adjustments. It adjusts all asymmetric elements to be centered and symmetrical, which makes it easier visually, and the structure is clear at a glance. The symmetrical layout also brings another advantage, that is, good scalability.
MIUI for TV 3.0 will also be concise to the extreme. No poster is needed. The background of the entire page is the poster. This realizes a new feature, an immersive and unbounded desktop. After the interface is open, the TV size is almost larger. The details page can help users make the final movie watching decision, so next, MIUI for TV 3.0 redesigned the details page.
At present, mainstream film and television applications on the market are full of information that is not related to movies. Users need to find information related to movies in dozens of information. MIUI for TV 3.0 deletes the complex and makes it simple so that the details page only gives the most core information of the movie and the 3 most relevant extension recommendations.
From the details page to the playback, there is usually a page jump, but as long as there is a jump, it will distract the audience. In order to continue the sense of immersion, MIUI for TV 3.0 simply let this process disappear and start playing from the details page. The exquisite details page is almost a part of the feature film.
The animation design system for mobile phones and computers is already mature, but compared to mobile phones and computers, TV has different interaction methods, viewing distances, and screen sizes. Therefore, MIUI for TV 3.0 has made a set of animation systems that meet the interactive habits of large screens.
The interactive features of the TV determine that there must be a focus on the page. Based on the focus, the remote control is used to control its up, down, left, and right. Xiaomi has redesigned a new focus animation, so that the focus to the focus moves like the center of the ripples, so that the animation occurs immediately, ensuring rapid response; the farther away from the focus, the longer the animation time lag, which is gradually completed, weakening the large area of the page The dazzling feeling brought by the change.
It can be said that MIUI for TV 3.0 is the first product to systematically optimize animation on the big screen. At present, the 82-inch series of Mi TV Master has been launched, and users can experience it first.
Mi TV Master Verdict
Let me talk about the 82-inch Supreme Commemorative Edition of Mi TV Master, its significance is no less than transparent TV. This is because in the TV field, although Mini LED has the ambition to eliminate OLED, there are currently very few responders. Xiaomi entered as a member of the first echelon and used it for its top flagship TV, which undoubtedly gave followers confidence.
Mini LED material has its natural advantages. Although the essence still belongs to the principle structure of LCD, compared with traditional LED TVs, the number of dimming divisions can be made more detailed, achieving high dynamic range (HDR) and high contrast effects. The improvement of the camera also has a greater effect, especially better dimming can effectively improve the color gamut performance, and can also shorten the optical distance to reduce the thickness of the whole machine to achieve thinner requirements. Compared with the OLED screen, because it is not organic, it can avoid the burn-in problem of the OLED screen and prolong the service life while achieving a similar ideal effect.
Of course, Mini LED TVs are not perfect. More detailed partitions have higher requirements for the TV’s backlight driver board and the local light control algorithm on the software, and it will take more time to experience and verify in the future. For Xiaomi, after exploring LCDs and quantum dots, the launch of Mini LED TVs this time also means to continue to raise the overall brand image of Xiaomi TVs.
Going back to the 82-inch commemorative version of the Xiaomi Mi TV Master, it will never lack stacking materials while exploring new material screens: it uses an 82-inch 8K ultra-high-definition screen with a resolution of up to 7680×4320, which is four times 4K and 2K. 16 times, 178° viewing angle, 120Hz flow rate screen, supports up to 8K 120Hz MEMC ultra-high speed motion compensation.
In terms of performance, it is equipped with a Novatek72685 8K TV chip, and it can play 8K 60Hz extreme video which makes desktop CPU and graphics card run hard for a long time.
And this is a real 8K TV. Not only the chip realizes 8K decoding, but the entire 8K process from the screen, algorithm, interface to content achieves full channel 8K decoding—that is, in 5G, USB 3.0, HDMI 2.1, Gigabit wired Ethernet All channels such as network ports can decode and transmit 8K content.
Of course, not every family can afford a huge screen TV such as the Mi TV Master 82-inch Extreme Commemorative Edition, which costs 49,999 yuan. This has the meaning of the 82-inch Mi TV-with a relatively low threshold. Into a high-quality 82-inch giant screen TV.
The overall quality of the 82-inch Mi TV for 9999 yuan is quite good at this price. It uses an 82-inch 4K ultra-high-definition screen with a resolution of 3840*2160, a 178° viewing angle, a DCI-P3 93% wide color gamut coverage, and 120Hz. Refresh rate, 10bit panel, 1.07 billion colors, the screen quality is among the LCD material screen TVs of the Xiaomi brand and maybe second only to the 82-inch Supreme Commemorative Edition of the Big Brother Master.
The MTK 9650 high-end TV core, which is the same as the 65-inch Mi TV Master, has been analyzed in-depth before. This is a typical high-end platform that can support 4K 120Hz decoding. With 4+64G storage, it meets the normal performance of this price.
On the premise of sufficient budget, the Xiaomi Mi TV Master 82-inch Extreme Edition may be the only 82-inch 8K resolution Mini LED giant screen TV on the market. Regardless of specifications, appearance craftsmanship, and actual experience, it has reached the Xiaomi brand’s The most luxurious, in the author’s opinion, it is even more meaningful than the previous transparent version, don’t miss it!
If you are only looking for a high-end giant screen TV that is good enough for home use, it is obvious that the 82-inch Mi TV can benefit more families and is also a pretty good choice.
