Mi TV has taken a lot of actions this year, and the most important is the launch of the high-end product line "Master" series.
In June, Xiaomi released the first Xiaomi Mi TV "Master" 65-inch OLED, and in August it launched the second "Master" series of Xiaomi transparent TVs. After only one month, the Mi TV Master series has made another move. This time it brought two 82-inch LCD TVs, one of which was also called the Supreme Commemorative Edition, and was obviously another "Super Big Cup". "product.
Three ultra-high-end models have been released in a single quarter, and with different characteristics. This continuous bombing strategy is like a run-up jump into the swimming pool. The flagship TV pool suddenly ushered in spoilers.
The tasting meeting arranged by Xiaomi was quite a hermit style of "wine fragrance is not afraid of deep alleys", and the tasting meeting was arranged in a villa area near the suburbs.
In this four-story villa that requires elevator access, we saw two new 82-inch Mi TVs from the Mi TV Master series.
This is the strongest specification of Mi TV so far
The first thing to note is that whether it is screen shot or live video, it can never truly reflect the expressiveness of the TV picture, especially when there are two TVs in comparison, it will be more inaccurate, so I don’t recommend everyone to watch the video only. Or draw a conclusion with just a few pictures. Whether it is a good conclusion or a negative conclusion, it is most likely to be inaccurate.
This time, Xiaomi TV "Master" 82" released two versions (the following is divided into standard version and supreme commemorative version), of which the standard version is weaker and the price is cheaper, at 9,999 yuan, while the supreme commemorative version has specifications Very strong, including Mini-LED and other technologies are exclusive to the Supreme Commemorative Edition, and the price has naturally risen, reaching 49,999 yuan.
Since the specifications of the Supreme Commemorative Edition are very "top", I don't want to talk nonsense, and just start looking at the specifications and personal subjective experience.
The panel specifications of this Mi TV Extreme Edition are quite powerful. This LCD panel comes from Samsung, with a resolution of 7680×4320, a true 8K resolution, and supports native 10bit color, 120Hz refresh rate, and DCI-P3 color gamut coverage. 98%, using Mini-LED backlight technology, which Xiaomi calls "Star Screen Sharp Shadow Backlight System Premium Edition", with 960 light control zones.
About what Mini-LED technology is all about and what obvious benefits it can bring, we will talk about it later.
From the perspective of image quality, I personally feel that there is nothing to be fuss about at the home level. The brightness will be too high when 100% backlight is used. It is recommended to adjust it to 70% or lower. But OLED TVs need to be adjusted to 100% to get the best results.
Watching the first episode of "The Silent Truth", which is currently in the limelight, some scenes are darker, and here will be a test of the TV algorithm's adjustment of the partition light control. In fact, Xiaomi's algorithm is quite clever and did not appear. For some situations where the details of the dark parts are not clear, if you think the overall picture is too dark, you can increase the backlight brightness (actually, in order to shoot at the scene, the backlight brightness is far from 70).
In the image settings, in addition to the advanced settings and expert modes that have already appeared on the OLED, there is also an option for "fine light control". This is the option to start the local dimming strategy, so that the partition light control can work under the Xiaomi algorithm.
After turning on the option, you can find that the brightness in the middle has increased significantly. The light control strategy has increased the brightness of the displayed content and white characters in the screen, but the dark parts around it still maintain a very pure dark field performance.
As for the display of brighter scenes, it is the strength of this TV. It can present clear, sharp and beautiful pictures at very high brightness. Some 8K display sources are attached to the scene, which is really enjoyable visually.
However, there are some minor problems. For example, because the resolution has reached 8K, the interface resolution of the Xiaomi TV system (beta) on site has not kept up, so if you look closer, you will find that the system interface display is a bit fuzzy, but this is not For the official version of the system, Xiaomi said that it will optimize related issues in the future.
In addition to the picture quality, let’s talk about the design of this TV. On the whole, it is still a full-screen design that Xiaomi is good at. The frame is quite narrow as a whole, and the screen-to-body ratio is as high as 98%. The base is made of sufficient materials for overall stability, and it is very interesting to make a slightly rotating design. Both sides can be rotated within a range of 15°, and a total of 30° viewing angle can be adjusted.
The audio part has a more "high-end sense" and adopts an automatic retractable design, which Xiaomi calls "Sound Wings". It's a bit like erecting two Soundbars and hanging them on the left and right sides of the TV. A similar design is basically only seen on flagship TVs.
There are a total of 8 built-in sound units, bi-amp electronic crossover, bass 20Wx2, medium and high frequency 10Wx2, and a large cavity design of 2×2.5L. This sound system also supports Dolby Atmos 2.0 and is compatible with Dolby 5.1 and 7.1 video sources.
The sound field of this sound system is relatively large. Compared with the large sound cavity sound underneath, the design on both sides will have a better sense of stereo and surround sound, but it will not be very exaggerated in the volume of the automatic retractable design. .
Turning to the interface on the back, the Mi TV Extreme Edition has 1 HDMI 2.1 interface and 2 HDMI 2.0. It will have good support for next-generation game consoles such as PS5 and Xbox Series X, but if you have both A bit robbed.
More importantly, there are two USB 3.0 ports, which make up for the regret of the OLED version. Others like Gigabit Ethernet port, AV interface, etc. are also complete.
It is worth mentioning that there is a very small interface in the arrangement of these interfaces. To be precise, this is not an interface but a SIM card slot. That's right, this Mi TV Extreme Edition supports 5G mobile networks, and it is an NSA/SA dual-mode network.
The SIM card supports hot swap. The network icon will not change when connected to Wi-Fi. After disconnecting Wi-Fi, mobile data will be used. The original Wi-Fi signal position will also become a 5G signal.
From a practical point of view, TV as a home appliance product should always be covered under the Wi-Fi network. Supporting mobile networks does not seem to make much sense. The product manager told me that 5G is a future-oriented reserve of this TV. Technology, if 5G is applied to TV within a few years, this TV can also keep up with the trend. Other aspects include 4GB+256GB storage.
If the greater role of the Supreme Edition is to "show muscles", another 82-inch TV in the Xiaomi Master series released at the same time is very "practical". We will call it the standard version for the time being (in fact, there is no suffix).
The biggest difference between the two is on the panel. The standard version is a 4K TV with a resolution of 3840×2160 and supports 10bit color depth, but it is achieved by 8 shakes 10, and it also has a 120Hz refresh rate and 93% P3 color. Domain, slightly lower than 98% of the Supreme Commemorative Edition.
Although mini-LED technology is not used, this TV still has as many as 240 light control zones, each with two lamp beads, a total of 480. Although the backlight control is not as delicate as the Supreme Edition, it is comparable to or even surpassing most flagship TV products, and the contrast ratio has reached a very high 140,000:1.
The peak brightness is 1000nits, which is close to the Master OLED version, so it also supports mainstream HDR formats such as HDR10+ and Dolby Vision, so there is no need to worry about the display effect of this TV will be different from other high-end TVs.
The difference from the Supreme Commemorative Edition is that the standard version does not carry a cool auto-retracting speaker, but uses a 6-unit, 2x15W sound unit combination, 2 low-frequency units, and 4 mid-to-high frequency units. Compared with the extreme version, the sound field and thickness are a bit weaker, but it is also in line with the performance of this price range.
What's interesting is that although it does not support 5G networks, this standard version of the interface is equipped with 3 HDMI 2.1 interfaces. Compared with the Supreme Commemorative Edition, the storage space has been reduced from 256GB to 64GB.
What Mini-LED brings to Xiaomi TV
As far as I know, the Mi TV "Master" 82" Extreme Commemorative Edition may be the third mass-produced TV on the market that uses Mini-LED technology.
If you don't have any more familiar knowledge about Mini-LED technology, then I will mention another product that uses Mini-LED technology-Apple's Pro Display XDR monitor.
After so much preparation, where are the advantages of Mini-LED? In fact, it can be summarized into two points:
1. The high number and small volume of lamp beads bring more partitions to control light, which can significantly enhance the contrast of the picture
2. Because more LED light sources are put in, the brightness of the screen can be higher
We all know that picture contrast refers to the measurement of different brightness levels between the brightest white part and the darkest black part of the picture. If you want to improve the contrast, you need to make the dark part darker and the bright part brighter, so that the picture can present a larger dynamic range and provide a better picture effect.
If you want to control the light and dark changes in every part of the picture, the ideal situation is that each pixel can be controlled separately, such as OLED and micro-LEDs whose backlight modules will be pixel-level in the future.
However, OLED itself is limited by material life, burn-in and other issues. At present, the peak brightness is extremely limited. The peak brightness for displaying the HDR effect is about 1000nits. The micro-LED technology is still being reserved for the future, and there is no actual mass production.
Mini-LED can be said to be an intermediate technology from ordinary LED backlight module to micro-LED backlight. Its backlight bead volume is smaller than the current backlight module, so it can achieve more precise control and also has more Multi-zone control light.
Here is a little talk about what is zoned light control, which means that the screen of the TV is divided into several areas on the backlight control. The backlight intensity of each area can be controlled independently, so that the highlight part of the picture can increase the backlight intensity display More pure white, while the dark field part reduces the backlight intensity to display purer black, the purpose is to improve the contrast between the light and dark of the picture. The more the number of zone control lights, the finer the control in theory.
At present, TVs with partitioned light control are relatively high-priced mid-to-high-end TVs, and the number of partitions ranges from dozens to hundreds. A typical example is Huawei Smart Screen V75 with 32 light control partitions, and Sony 65-inch X9500G There are 60 zones to control the light. TCL and Toshiba like to do more partitions, with 120 or even as many as 240 partitions.
Remember how many zones control the light in the Mi TV Extreme Edition using Mini-LED? The answer is 960. Through 60 independent chip control, each chip controls 16 zones, each zone has 16 lamp beads, a total of 15,360, and each zone can achieve 4096-level brightness changes.
The fine light control ability has brought about a significant increase in contrast. According to official data, the Mi TV Extreme Edition can achieve a contrast ratio of 400,000:1, which is no less than OLED products that can turn off pixels. Of course, this is only a theoretical figure, and it is naturally impossible to achieve this high in actual viewing, especially when displaying SDR content.
Another amazing improvement data brought by Mini-LED is brightness. In our cognition, the peak brightness that can generally reach 1000nits is already at the top level. If the backlight intensity is increased, it is limited by the limited number of light control partitions, which can easily cause the overall picture to appear white, and the afterglow effect will also very obvious.
The super-multi-zone light control and the number of lamp beads brought by Mini-LED also enable it to support higher brightness. According to the official data, the peak brightness of the Mi TV Extreme Edition can reach more than 2000nits (10% window brightness). The product manager told me that this is still a conservative number, and the actual limit is around 2500nits.
Is such a high brightness useful? Because someone will say that this kind of brightness is not necessary at ordinary times, but will "bright blind."
Here is a little talk. Although the current reference materials cannot determine the human eye's recognition limit for brightness, the outdoor brightness under the scorching sun can reach 100,000 nits, so even a 2000 nits TV is for real outdoor brightness, even some Indoor lighting is still impossible to restore.
Since Mini-LED has brought so many display enhancements, are there any side effects?
In the communication with the product manager, I learned that one of the problems encountered when making this Mi TV Extreme Edition was heat dissipation. Since there are tens of thousands of lamp beads in the backlight module, the peak brightness has reached 2000nits+, and light and heat are inseparable brothers. High brightness will inevitably bring more heat.
Therefore, a very huge heat dissipation design is actually used on the back of the TV. There are cooling vents in most parts of the entire back, not like the master OLED TV, where the upper part is a very thin panel.
Including Apple's Pro Display XDR monitor is the same. Why are there so many gaps on the back? Many people say that intensive phobia is a crime. In fact, using Mini-LED technology in a small size will cause more heat.
But compared to this side effect, Mini-LED is undoubtedly the most anticipated change in the field of screens before micro-LED matures.
Only when there is pressure, there is motivation, and when there is motivation, there is progress.
The launch of the Master series and the launch of products with different prices and features within a short period of time all show that Xiaomi TV really feels the pressure.
Although from the perspective of product definition and research and development time, it cannot be said that these pressures gave birth to the high-end series of "Masters", but this pressure should indeed accelerate Xiaomi’s determination to sprint to the high-end, and finally it does bring consumers time and time again. The surprise came, and it was also a powerful counterattack to the market's increasingly "unthinking" remarks about Xiaomi TV.
For the first 65-inch OLED TV in the Master series, my opinion at the time was "very outstanding". For the second transparent OLED TV in the Master series, my evaluation was "very amazing". Then I will see this one. In the Mi TV Extreme Edition, the inner evaluation has been changed to "very good X".
If I said last month that I still had some doubts about the "Master" series, I was worried that the "Master" series, which had already established a preliminary reputation, would gradually become a show concept series after the launch of the transparent electric OLED TV, then this Xiaomi TV The supreme version has dispelled my doubts, this high-end is really standing.
