Preface: On the Basic Cultivation of Television

First of all, "one piece of money, one piece of goods" is still applicable to TV, because the biggest cost of TV is the screen (70% or more), and the price of the screen roughly determines the level of TV, so it is no doubt that you should watch the "screen" before buying TV. At present, the 4K TV market is mixed, with a large number of ultra-low price 4Ks emerging, including a large number of low-end "fake 4K" WRGB panels. Of course, there are also differences between different televisions, so there is a cost performance ratio. Xiaomi TV 3S 55 inch, 3499 yuan, just look The price is really in the same size, which is cost-effective What's the truth? Let the old driver tell you slowly.

These are the points Messi thinks a reliable 4K TV needs. Let's compare it with the 55 inch Xiaomi 3S. Let's see which parameters of Xiaomi are eye-catching and which shortcomings are not mentioned by the authorities.

Obviously, through simple analysis, 55 "Xiaomi 3S ， It has met the requirements of the ideal midrange computer in many aspects , especially in Screen aspect However, there are also obvious shortcomings. For example, the 6A938 core emperor does not use the A72 architecture, Lack of MEMC function This may also be limited by the cost. Let's verify the effect of Xiaomi's choices.

Unpacking: Satisfied with workmanship, ordinary remote control

Millet TV is packed with wooden frames, which is praised for its firmness. However, the cross express logistics did not help to dismantle the frames and inspect the goods in person, which needs to be complained.

The foam packaging is firm, and there are wooden sticks inside for reinforcement. 　

Comes with 2 metal support feet and a slip resistant design.

Less accessories: 4 screws+1 (spare), infrared remote control (with battery). It is a pity that there is no standard Bluetooth remote control and no set-top box conversion cable.

Easy to fix: four screws, easy to install.

Front first glance: Thin, narrow 。

Measured thickness: 9mm above, 10mm at the side (iPhone6=7.5mm). By observing the nickel, you can directly see how thin the frame of the Xiaomi TV is. 　

The frame is made of frosted aluminum alloy patch, and the stitching can still be seen at the corners, but the gap is not obvious. Of course, you can also vaguely see the small black edges.

The bottom bar of Xiaomi TV has a narrow frame, and the infrared remote control receiver protrudes below the bottom, The MI standard has excellent texture.

Xiaomi's aluminum alloy frame is made of metal patches, not real metal frames, but aesthetic and cost considerations.

The herringbone support has good stability, and the bottom is equipped with anti-skid rubber pad, which has certain anti-skid and protection. 　

The back of Xiaomi TV 3S adopts the popular design of narrow top and wide bottom. The top metal brushed panel has a good texture, but no stiffeners. Maybe it is for the sake of thinness and beauty. The bending resistance will be tested by time. 　　

The metal patch strip is fixed by screws. The edge is well made and does not cut hands. 　

In the middle area, there are wall hanging holes on four sides, and Xiaomi uses plastic nuts for hidden decoration to achieve unified overall style. 　

Left side: Xiaomi's small flat plug is highly praised, which is also a point repeatedly mentioned by Xiaomi when focusing on the "craftsman spirit". The actual workmanship is really good, small in size, it can be inserted into a crowded socket without conflict, and the vertical design is not easy to break, and there is no problem with plugging.

There are two rows of interfaces on the right, and the lower row is antenna, network cable, audio, and traditional AV ports, which are not commonly used, so they are set in the rear.

Side: 2 HDMI, 1 ARC (audio interface), USB3.0 and 2.0, these common interfaces are placed on the side, convenient for plugging, reasonable design, and rich interfaces.

The top row of cooling grids is also ultra-thin at the bottom, so the cooling area is also compressed. Long time operation at high temperature in summer may be a big test.

Appearance summary:

Xiaomi 3S, which focuses on thin, is extremely thin. Although the frame is in the form of plastic+metal strip, it is not as exquisite as ID without frame or narrow frame, but it is beautiful and grand in details, HDMI2.0，USB3.0， All audio ports have ARC interfaces. The only pity is that there is no standard Bluetooth remote control, but infrared design. In terms of 55 inch appearance and workmanship, Xiaomi 3S can be praised.

Picture quality: surprise and disappointment

1、 True 4K (RGB verification)

Measured RGB, true 4K in three colors, WRGB and RGB are in the low-end panel, The advantages of RGB are obvious. The high-end four colors are not in the scope of discussion, so buy the low-end RGB panel. 　　

2、 Light leakage control: satisfactory

Due to its own material, the LCD panel cannot be lit. It needs backlighting to display the true color. Of course, light leakage is inevitable. High end LCD TVs often use hundreds of backlight partition panels to control light leakage. Low end TVs often do not have backlight partition technology. It is also a backlight zone. The number of backlight zones determines the black field and blackness purity.

Xiaomi 3S can use backlight zoning technology in entry-level TVs, which is better than no backlight effect, and is worth praising. However, due to the small number of backlight zoning, the light leakage control has not changed significantly, and the lower light leakage is more serious, which is the difference that high-end and low-end TVs pursue in backlight zoning.

3、 Brightness: highest brightness mainstream, average uniformity

Millet TV's full open backlight, the measured maximum brightness is 375nit, and the upper and lower brightness is about 280nit. The overall brightness is not very uniform, and the brightness data can only be calculated as the average level of entry level. The better backlight brightness can reach 400 nit, and the high-end top level can reach 800-1000 nit. The higher the brightness, the more detailed the brightness level of the picture.

4、 Resolution, color transition

4K resolution is up to standard, with clear text and visible gaps.

Color performance: the triangle in the yellow part is not completely overlapped with the green and red parts, but in terms of visual angle, the ball on the right is too natural.

5、 265 Excessive gray scale: general

Generally, 4+4 or 6+6 can't be seen clearly in the low end 4K, so can the Xiaomi TV 3S, and 6+6 can't be seen clearly in the upper left corner.

6： Color accuracy: (color gamut)

The common entry-level NTSC color gamut is only 75%, and the mid end can reach 85% - 90%, while the high-end top end can reach 100% or even 110%. The higher the color gamut, the more accurate the simple understanding of color display, and the more beautiful the color.

Display comparison of other brand NTSC color gamut 75% and Xiaomi NTSC color gamut 85% at the same price.

Comparison of blind test on real map

A bright red sports car. The front car is orange, and the rear car is bright red.

Color optimization mechanism: Pay attention to the car color

skin colour: It's easy to see which one.

Image optimization: dynamic live shooting

It can be seen that the color performance of the upper TV is more accurate in processing people's skin color.

Reveal the answer: Above: Xiaomi TV 3S, below: its brand TV, Xiaomi TV 3S has a higher color gamut , the displayed color will be more realistic and colorful.

Lack of MEMC: poor dynamic smoothness

You may think that the picture quality of Xiaomi TV is very good, but don't forget that before, most of the scenes were static effects, but the actual scenes were dynamic. Xiaomi TV's Amlogic processor does not support MEMC (dynamic compensation) to improve picture smoothness, Messi has seen similar situations on other low-end televisions, which should be considered in terms of cost.

Comparison of MEMC switch effects (measured by a television in messi)

Xiaomi TV does not have MEMC. At present, many other entry-level TVs also lack this function. In fact, this function is very important for improving the TV picture. Some TV pictures are "comfortable", in which fluency accounts for a large proportion, It is acceptable for Xiaomi TV to watch low dynamic TV dramas, but if you want to watch ball games or external games frequently, this Xiaomi TV may not be your dish when the dynamic picture output is high.

Image optimization: slightly sluggish, but optimized in place

Low end TVs often have a lag in image optimization rendering speed. When you open a photo, it will blur for a few seconds, and after a few seconds, the color will change. High end TVs basically have no delay, while low-end TVs can detect that Xiaomi TV 3S has a lag of about 1 second, which is not bad compared with the other TV's lag of about 4 seconds. There are few negative image optimization situations, But it is far from the high-end.

Other live photos:

Summary of picture quality: there is a good screen, but the dynamic appearance is ordinary

Messi almost thought Xiaomi TV was An entry-level TV with good picture quality , of course watching The color restoration is accurate in static and low-speed images , but Xiaomi TV 3S Chip reason does not support important MEMC (motion compensation), resulting in the smoothness of high-speed dynamic images. If you only watch ordinary TV programs, the color of Xiaomi TV 3S can meet your needs; But if you often use it to watch ball games or external games, it is not suitable.

Performance: enough decoding, average function

Xiaomi, which has always been famous for its hot hardware, has adopted the SoC Unusual Amlogic processor of A53 architecture (4 * 1.8GHz), there is a certain gap between the current hot A73 architecture of the 6A938 TV core, which is basically equal to the 6A928 (sub flagship) positioning.

This Amlogic chip supports backlight partition technology, HDR technology, but does not support MEMC (motion compensation) 。 Obviously, the function support of this chip is not as good as that of the more perfect Mstar 6A928. Perhaps cost considerations have made Xiaomi 55 inch all-in-one choose Amlogic.

In terms of running points, Amlogic's performance is mainstream and not outstanding.

Hard decoding: mainstream.

1、 [Paris Tower]: AAC/HEVC, 30 frames, low bit rate

Audio synchronization, perfect play, drag smoothly.

2、 [4K 123 four primary colors]: AVC/AAC, 30 frames, 80Mbps code rate

Audio synchronization, perfect play, drag smoothly.

3、 [Hokkaido and Tokyo]: Video AVC, audio AC-3, variable frame number, code rate 112Mbps

Audio synchronization, perfect play, drag smoothly.

4、 [AOA_Miniskirt]: HEVC/AAC, 60 frames, 26Mbps bit rate.

Play and drag smoothly and play normally.

5、 [4K girlhood 120fps]: video AVC, audio DTS, 120 frames, 101Mbps bit rate

Cannot play

6、 [Duck flew 2160P]: Video AVC, no audio, 30 frames, 243Mbps bit rate

Picture stuck

Performance summary: (about Amlogic chip)

Xiaomi may not use the mainstream Mstar6A938/6A928 to control the overall cost, Amlogic has no problem with its decoding ability. It can easily decode 60 frames of 4K. Backlight partition is selected between MEMC and backlight partition (at present, most low-end TVs do not have backlight partition). The original intention of Xiaomi TV's 3S design should be to emphasize the concept of good screen=good picture quality, but in terms of TV display technology, Messi believes that on low-end TV, The MEMC function is obviously more important than the backlight partition, which is also the reason why Messi is not satisfied with Xiaomi TV.

[messi view] Importance of the three: good screen>MEMC technology>backlight partition technology

Good screen or good picture quality technology is indispensable. Xiaomi TV's pursuit of screen is gratifying, but its choice of TV technology may be somewhat biased. Most low-end TVs in the market have poor screens and do not support backlight zoning, but support MEMC (motion compensation). Xiaomi prefers the first two, while some manufacturers choose the latter. The cost of low-end TVs is limited, and they cannot always take into account. Therefore, low-end TVs are still far from good picture quality.

UI&Resources: Highlights

Power on: slow, but no advertising

At present, many TVs can be turned on within 20 seconds. The 30 second time of Xiaomi TV 3S needs to be optimized. Fortunately, there are no annoying advertisements on the boot page.

Interface setting: intuitive tiling, but also more human

The UI of Xiaomi TV adopts the current mainstream tile browsing mode, which is very intuitive, but Xiaomi's home page does not have the access to quickly launch the app. Every time you open a third-party app, you need to find it in multiple steps, which is inconvenient for friends who prefer to watch it with third-party apps (non VIP).

Image settings:

Dynamic backlight/3D to 2D should be two highlights of Xiaomi TV, which is actually useful. However, due to low technical specifications and frequency of use, its practicability is not high.

Sound output: external speaker

Both local audio and external audio can be played through HDMI (ARC) interface.

[Highlight 1: Artificial intelligence puzzle wall]

The biggest feature of AI is intelligent push. If you watch a certain type of TV series, TV will push you similar types of TV and movies. For example, if you watch a martial arts film, it will push you other martial arts films. Xiaomi has accurately classified each TV set, which is an interesting design and very practical.

[Highlight 2: Combine the four giants to become a resource hegemon]

IQIYI, Tencent, Youku, Sohu: Highly integrated, with the most complete content of the whole network

First of all, in terms of resources, these four resources are indeed very powerful, and there are many free content. It is a great surprise for consumers that Xiaomi can integrate all these major copyright vendors into the UI. However, Xiaomi has only done simple integration of content (it can also be achieved by installing APP alone), and can also cooperate in depth in terms of video source definition.

TV series: basically covering the whole network, very powerful

Thanks to the rich free copyright content of the four major platforms, the free content of Xiaomi TV 3S basically covers the vast majority of popular dramas in the market, and more importantly, it also brings the independent dramas of each platform.

Film resources: no special advantages

Compared with TV series, the film update speed is relatively ordinary, VIP movies have no advantage over third parties.

[Highlight 3: Xiaomi VIP, annual package price is very affordable]

The four content providers mentioned above can also download third-party on-demand software if they only watch free resources. Each VIP is 20 yuan, and the average annual price of millet bags is 30 yuan per month, which is a very cost-effective price. This is the most attractive part of this Xiaomi TV, giving consumers a real late discount.

Built in application: general

From Xiaomi app store to Mijia's smart home TV, and then to projection software, while satisfying users to expand third-party applications, it has also opened up the Xiaomi home ecosystem. At present, the entire home ecosystem should only be Xiaomi. However, the practicability of the internal software is relatively general. Many resources cannot be found, and a third-party application store is still needed.

Third party APP: unlimited installation, convenient

Due to well-known policy reasons, all major TV manufacturers have blocked the conventional way of installing third-party APP, but there is no doubt that third-party live broadcasting and on-demand APP greatly meet the needs of viewers themselves. Xiaomi has a clear conscience in this respect. Instead of enabling third-party APK file identification through anti human engineering mode, it can directly allow "installing applications from unknown sources" in "settings", and then install third-party APPs.

Switching function: practical

Double click Home to switch or clean one or more backstages. This interaction is good, and it is more practical for Xiaomi.

Infrared remote control: average function, good sensitivity

First of all, infrared remote control is definitely not as convenient as Bluetooth remote control. There is no standard Bluetooth remote control, which is limited in the control range. In addition, there is no voice function, so the functionality is very general; However, the actual sensitivity is fairly good, quite handy.

Screen projection:

Xiaomi screen projection can be downloaded from the mobile phone, which can project photos and videos from the mobile phone to the TV. Game synchronization seems to be not good. Individuals still prefer third parties such as the Wukong remote control. In addition to screen projection, they can also install practical APP wirelessly, with rich resources.

UI&remote control summary:

Mi TV The UI integrates four mainstream media, with rich free content , and more importantly The annual package price of Xiaomi VIP is quite affordable It is quite tempting to spend one VIP price to enjoy four exclusive broadcast resources. However, the UI home page does not quickly start the third-party APP. The settings need to be improved, No standard Bluetooth remote control , relatively ordinary in function and control.

Summary of Xiaomi TV 3S

advantage:

Ultra thin shape, excellent workmanship

True RGB 4K screen, wide color gamut NTSC85%, accurate color

Static and low-speed picture color optimization in place

Abundant HDMI/ARC/USB3.0 interfaces

Exclusive ownership of four copyrights, high integration of free resources

Xiaomi VIP is affordable and has many contents

AI recommendation is practical

Outstanding cost performance of the same size

Disadvantages:

The remote control is not Bluetooth, and there are few accessories

Normal light leakage control (few partitions)

Average screen brightness and uniformity

Lack of MEMC, general dynamic performance

Slow startup speed, UI humanization needs to be improved

The 55 inch Xiaomi TV 3S has achieved the extreme price in some places, especially the LG RGB screen with NTSC color gamut of 85%, which is the most important screen of the TV. The color display is superior in the same level, but the Amlogic processor does not support the MEMC (motion compensation) function, resulting in a general dynamic appearance, so the overall image quality and image score are reduced. Messi personally believes that the most attractive thing about Xiaomi TV 3S is its super low price VIP content. It is very attractive to watch the independent dramas of four TV stations for a monthly fee of 30 yuan a year. If you are pursuing high cost performance, beauty or drama, Xiaomi TV 3S (55 inch integrated) can meet your needs; If you like the content and size of Xiaomi and have higher requirements for appearance, perhaps the 55 inch split is a better choice.

　 　 Recommended population:

Entry level budget, living room display requirements

Ultra thin control, beauty control

It is very suitable for chasing dramas

Not suitable for people:

Ball game stage
