preface

As the leading brand of Internet TV, LeTV Super TV has always been the focus of market attention and one of the first choices for users to buy TV. Three years since the establishment of LeTV brand many High cost performance comprehensive strength powerful Our TV products have gained good sales and good reputation.

exceed As the fourth generation of LeTV Super TV, the 4 X55 Super TV has achieved all-round upgrading and upgrading. Compared with the previous generation of products, it has achieved comprehensive evolution and upgrading. It has brought users unparalleled hardware configuration and seamless viewing experience in the same gear. TV, music, movies, games and learning are all proficient, and all aspects are perfect, According to the official propaganda, it is not a TV station but a complete set of large screen Internet ecosystem. Then whether the product is really as advertised, let me experience it~

Unpacking

Before receiving the goods, I was still considering whether there would be any problems with the distribution and installation of a 55 inch giant. Therefore, I consulted LeEco customer service several times, and the customer service staff of LeEco patiently answered my doubts.

The TV was ordered in the official LeEco Mall. Shunfeng will be responsible for the delivery. Before delivery, the express will call in advance to agree the delivery time, but Shunfeng will not be responsible for installation and commissioning. Therefore, after receiving the goods, the first thing to do is to check whether the outer packaging of the product is in good condition, and sign for it after checking.

According to the regulations of LeEco, users are not allowed to unpack and install without permission. After receiving the goods, users can call LeEco's customer service phone or make an online appointment for door-to-door installation. Within one year of purchase, users can install the base and the rack for free. LeEco is solely responsible for replacing any problem found during the installation process, However, LeEco is not responsible for any problems found during the user's private installation.

According to LeTV's explanation, the waiting time for delivery is long due to the high sales volume. The author has had a hard time waiting from placing an order to receiving the goods. In addition, according to LeTV's regulations, once the delivery address of the TV is determined, no further changes can be made. Therefore, if you want to change the address, you can only negotiate with the express, so remind everyone to pay attention before purchasing.

There are two packing boxes in total. One is the TV package and the other is the base. Both boxes are very large, which is one circle larger than the 50 inch TV I bought before. The packing box is also very strong and well protected during express transportation. This should be praised for Shunfeng! The author and the express brother moved the giant to the home to check it and signed for it. The express brother sighed: Fortunately, it's the second floor. Ha ha, I think so too (lower floor, you know)~

Remote control and other major accessories.

Game controller set.

In addition to the base, there are two accessory boxes. The white box is used to hold the remote control, instructions, adapter cable and power cable. The other kraft paper box is used to hold the standard game controller, which is very enjoyable to play games. It will be shown later. In addition, optional accessories include a somatosensory camera, a LeEco wireless speaker and a LeEco somatosensory pistol, which are not included in the standard configuration (cloud base is also an optional accessory, which is not included in the standard configuration, so this is a bit problematic).

Appearance: ultimate design

TV Metal The frame is pasted with protective film when leaving the factory. To prevent the frame from being knocked, it can be torn off later. After tearing off the protective film, the TV shows its true color The overall body of the super TV is silver white, which is very grand and eye-catching. At the same time, the screen occupies a very high proportion. There is no unnecessary decoration on the front. The 55 inch 4K LCD screen has great visual impact!

LeTV Super 4 X55 Super TV adopts silver and white to form aviation grade aluminum alloy ultra narrow frame, which is very exquisite. It adopts seamless bending technology and diamond cutting process, which can not only make the ultra thin body more solid, but also greatly improve the beauty of the product. The visual effect is very amazing, similar to the frame manufacturing process of smart phones such as Xiaomi Note, It can be said that it is extremely beautiful when used on TV.

The logo designed by LeEco is in the center of the lower frame of the fuselage, which has a sense of technology and is much taller than the previous logo; Below the brand logo is the signal receiving area. When the TV is turned on, the signal light turns red. When the remote control is turned on, the signal light turns green.

The LeEco Super 4X55 has an ultra-thin body, with the thinnest part of the upper part only 9.9mm, which is comparable to the thickness of current mainstream smart phones. The appearance is excellent. The above picture is very impressive.

The USB3.0 interface of the somatosensory camera is located in the center of the top of the fuselage. With the somatosensory camera, you can play experience games in the game zone. But the standard configuration is not equipped with a somatosensory camera, so unfortunately, the author cannot show it to you. Users who want to experience it can buy it at LeMall.

At the lower right corner of the fuselage, there is the logo of Haman Katon, the emperor of the sound box world. The super 4X55 sound box is certified by Haman. I don't think many people don't know about Haman. What? You don't know. Well, I'll introduce it in detail later. In short, it's full of challenges~

Let's introduce the cloud base in detail. It adopts asymmetric streamline design and aluminum alloy integrated molding process. It is very beautiful, grand and light, but it is stable and safe to put on the TV. The disadvantage is that when taking photos, I feel that how to shoot the TV is crooked. At the beginning, I was worried about this for a long time, However, it is still good after getting used to it. It highlights the characteristics of LeTV Super TV in the same base design~

The upper part of the ultra 4X55 fuselage backplane also uses a large area of aluminum alloy material, shining silver light. It is not only very beautiful and solid, but also can enhance the heat dissipation capacity of the TV. The lower part of the back is a black injection molding board, and the middle is equipped with LeEco's new logo, which is full of technology!

The left side of the back is a common L-shaped interface design, with a total of 1 USB2.0 interface, 2 USB3.0 interfaces, 3 HDMI interfaces, 1 audio and AV input, network VGA interface, optical fiber audio output and antenna interface are relatively rich, which can well meet the diversified use needs of a variety of different users. I have many large capacity hard disks to place high-definition movies, plug and play. There is a great demand for USB interface.

On the right side of the rear panel is the detailed product information of Super TV, including model, voltage, power, Dolby Sound DTS Sound Effect Certification logo, MHL (mobile terminal HD AV standard interface ）And serial number.

There are large stereo speakers on both sides of the lower back of the TV. Harman Carton certification supports Dolby and DTS sound effects!

In addition to the screw holes on the wall, the screw holes for the anti tipping chain are also added below the TV back panel. The anti tipping chain is included in the accessories. To ensure the safety of the TV, it can be installed. This design is more user-friendly.

The heat dissipation part of the TV is made into a row of grooves, which can effectively prevent dust from falling into the TV.

Screen: Ultra HD

The above five pictures are 4K video live shots without any post-processing.

4K HD photo

LeEco 4X55 Super TV adopts 55 inch RGB true 4K (3840x2160) LCD panel, which supports HDR and motion compensation technology, has a higher dynamic range of brightness. The brightness of the whole machine is greater than 250ni, the response time is 8ms, and it has a 178 degree super large viewing angle. No matter where you sit in the living room, you can enjoy the same wonderful effect. With it, you don't have to compete for gold with your family anymore~Now let's test the basic quality of this screen through the screen master test.

First is the color test. The display color is bright and transparent, which is a high-quality screen. The color transition is smooth, which is a high-quality screen. According to the test picture, the screen display color is bright and transparent, which obviously meets the quality standard~

Next is the bad spot test, which is to observe whether there are bad spots by highlighting the solid background on the screen. After careful observation, the author did not find any bright spots and dark spots.

Then comes the advanced mode, where the geometric figure does not deform, the switching image does not have obvious jitter, and each line on the edge can be distinguished as a high-quality screen. After careful observation, it can be seen that the brightness adjustment color block can be clearly seen, and the text and eye change lines at various positions can also be clearly seen, provided, of course, that under the large screen, To sum up, this screen basically meets the standard of high-quality screen. Next, compare the 4K high-definition original picture with the actual picture.

The above is the 4K HD picture test: the sequence of picture changes is: 4K original picture, screen shot, and live shot.

Through the comparison of multiple 4K samples and 4K video live shooting, LeEco Super 4 X55 performs very well, with exquisite picture quality, high contrast, rich color, relatively bright picture levels, rich details display, and natural light and dark transitions. It can still display details in strong light and dark backgrounds, The actual display effect is more beautiful and bright than the picture (the live picture may not fully and accurately represent the effect of the screen due to the influence of light, and the human eye experience is the most accurate).

Sound effect: extremely shocking

Live shot of 1080p Terminator 5

As a movie controller, the author is keen on pursuing the ultimate audio and video effects. The shocking sound effect is crucial in the movie viewing process. The LeTV Super 4 X55 Super TV dubbing box has passed the strict standard certification of Harman Carton, and its recognition by Harman is the greatest affirmation of a speaker's sound effect! Now let's briefly introduce Haman, Harman/kardon Harman Carton Sound is a very famous top audio brand, headquartered in New York, USA. it It's BMW , Mercedes Benz 、 Waiting for luxury car brands Main points of Car audio supplier. The Group's brands include JBL Becker、AKG Wait a series Famous audio brand JBL alone is very powerful ！

The high standard hardware of LeTV Super 4, plus Dolby and DTS sound effects processing, enables all kinds of sounds to be restored with high fidelity. No matter watching blockbusters or playing games, you can get a pleasant and impressive hearing experience, which is completely enough for ordinary users! However, we should not expect it to be comparable to the professional integrated sound system. If we are very picky about the sound quality effect, we still need a set of integrated sound system. The author has long been optimistic about a set of JBL, but is shy of money~

Configuration: extremely strong

The LeTV Super 4 X55 Super TV has a very powerful configuration. The 4K ultra clear screen has been highlighted before. In addition, the CPU uses the MSTAR 6A938 model 1.7 Ghz 64 bit super processor and MaliT820GPU. The CPU consists of two A72 large cores and two A53 small cores, with a run score of more than 60000. It is rare to see such a powerful CPU configuration on TV; Moreover, it is also equipped with 3+32G super large memory, which not only enables the product to have excellent decoding capability, but also guarantees the smoothness of multitask processing and the response speed of the system. The author compared and tested that a large number of 4K ultra-high definition video plays very smoothly, and fast forward and fast backward do not have any jam. In addition, the TV system is also running smoothly, but in terms of the characteristics of Android system, the smoothness will definitely decrease after a long time of use, which can be solved through the upgrade of the system.

The configuration comparable to that of the mid end mobile phone is rare in the TV. While ensuring the smooth operation of the system, it also ensures that the super 4 X55 will not fall behind in a few years. Comparing the upgrade speed of the TV configuration with that of the mobile phone is different. Users can also install a large number of games, applications and other APPs to expand TV functions. The author installed two 300M games after booting up, with 22G of memory left, which is enough to install multiple large games and dozens of other applications. After a long time, the memory can also be cleaned up, because Android generates garbage very quickly.

System: extremely smooth

LeTV Super 4 X55 Super TV has a built-in Android 5.0 based EUI5.5 operating system, which can be upgraded to Android 6.0 based EUI5.8 after boot. Since 5.8 is not much different from 5.5, EUI5.5 is the main focus of detailed introduction.

EUI5.5 System Operation video

The super TV equipped with the EUI5.5 operating system runs smoothly. The system's operating interface is very simple. The first level menu basically contains all the videos you want to watch and the functions you need. You can switch through the left and right buttons. At the same time, the system's interactive interface is smooth and beautiful. It has a very accurate grasp of user needs. As an Internet based TV manufacturer, There are too many advantages and learning points for convenience compared with other hardware manufacturers.

LeTV Super 4 X55 Super TV Switch Test

The system boot up speed is also very fast, but every boot up there will be a forced 15 second advertisement, which should be the waiting time for the system to start up and run. Although it is not very long, the actual feedback will be different. I personally think that the advertisement screen that the boot up is to wait for is always better than the brand logo, However, some users may be disgusted with this practice~

letv Super 4 X55 randomly presents 16 month super members. When you start up for the first time, you will be prompted to activate members. After activation, you can enjoy a large number of free resources. The free LeEco members can also be used in TV, mobile phones PC、 Flat plate VR、 It can be used on seven platforms, such as cinemas and cars, to get through all the large and small screens. With the large content and massive resources of LeTV videos, videos can be played without advertising. You can enjoy yourself at home this summer. This is the advantage of LeTV!

Search: When the system is powered on, it defaults to the live interface. Press the left button to enter the search, which is divided into hot search, movie list, TV series list, animation list and guess what you like.

Live broadcast: Thanks to the powerful hardware configuration, the LeTV Super 4 X55 is equipped with LeTV's original nine channel live broadcast interface, and the nine channel images are still played smoothly at the same time; LeTV connects live broadcast and on-demand content. The channel classification is extremely diverse. All kinds of video resources are broadcast 24 hours a day. Audiences of any taste can easily find the content you want here. It's really a good news for lazy people. However, due to national policies (you know) and other reasons, there is no real live broadcast on TV, and the boxes are also dead, I'm here to complain about the three networks integration policy. It's really time to push it forward.

Synchronous cinema line: It is a long cherished wish of many fans to watch blockbusters at home without going to the cinema. For the author, it is worth experiencing as long as it is not more expensive than the cinema. LeTV system has opened a special area for synchronized cinemas to watch movies synchronized with cinemas without leaving home, but there are many problems. First of all, the films are not very well-known and the attention is not very high. What you really want to see is still not visible. Online on-demand is a new development trend in the film and television industry around the world, but there are still many problems. The disappeared killer is a good example, Before the release, the online broadcast agreement signed with LeTV was boycotted by several major cinemas. Not only was the domestic Crouching Tiger, Hidden Dragon 2 also boycotted in the US Netflix synchronous cinema. So the synchronous cinema is not a smooth road. But LeTV's innovation is still very worthy of praise. Come on.

Sports: LeTV has provided relevant content resources such as the Chinese Super League, the Olympic Games and the NBA. These days, the Olympic Games have just opened. It is also a good choice to watch the Olympic Games on the 55 inch screen.

shopping: I think everyone will instinctively repel when they see this. I have watched so many unscrupulous TV shopping advertisements. Do you want me to watch advertisements when I buy a new TV? So LeEco still has a long way to go to get through the whole ecosystem. Audiences have been poisoned by TV shopping. It is not easy to change their minds.

Children: This section is very good. I like it very much, but it's not I like to watch it, but I think this part of the content is really very practical for families with children, because it is just a stack of cartoons, and it also provides high-quality resources for children of all ages to learn and play. The most important thing is that it can be customized, which is good news for children and parents.

In addition, LeTV system also provides a super list function, which is rich in content, detailed and comprehensive in classification, and more user-friendly.

EUI5.8 System Operation

EUI5.8 is the latest version of Android 6.0 based system. It adds some new functions and improves some bugs of the old version. The system has a cleaner interface and more beautiful icons. The main difference is that LeEco Video has changed its name to LeSee to provide more comprehensive video content aggregation and intelligent recommendation.

I'm glad that it is not on the home page of the desktop by default. It needs to be adjusted to the first level menu of the desktop through managing the desktop.

Application: extremely rich

In addition to the main interface functions of the system, a large number of other tool applications belong to the application partition, which is very rich and complete. It mainly includes a series of utility tools such as app stores, system updates, music, browsers, file management, TV butlers, calendars, photo albums, cloud disks, etc. Users can use these software to better manage TV and enjoy various conveniences brought by intelligent Internet TV.

browser: The homepage of the web browser has the navigation of JD, Sohu and other common websites. The web page opens quickly. The mouse mode with the remote control should be good, but the cursor is very floating, but it is convenient to use it occasionally.

TV Housekeeper: TV butler provides functions such as garbage cleaning, system acceleration, application management, authority management, parental lock, etc., which are very practical; In particular, the parental lock can set the power on password, application lock and desktop lock to manage children's TV use in an all-round way, so that children can no longer worry about watching TV secretly affecting their learning~

In addition, application management, cloud disk, weather, calendar and other functions are also very practical. EUI5.5 encountered a problem when using file management to take screenshots everywhere. When copying a folder, the progress was stuck. After upgrading 5.8, this problem was solved.

Control: extremely convenient

The remote control of the super TV is very beautiful. The ergonomic design feels good. Although there are few buttons, the functions are very rich.

There is a microphone on the top of the remote control and a voice control key in the middle. Press the voice control key to say what you want to see, and the system will automatically search and locate. The search results are very rich. In addition, LeTV Super TV also carries an innovative voiceprint recognition system, which innovates and develops the interactive experience of the product. The other is the cursor mode, which is the air mouse. As mentioned earlier, the starting point is very good, but in the experience, the cursor floats violently and is difficult to locate accurately. The experience is not very good. I hope LeEco can improve its products in the future.

Pleased to see: ultimate content

As the most important part of the LeTV cloud ecosystem, LeTV video is a killer for LeTV. Compared with other TV brands, LeTV really stands out in the fierce red sea of TV competition because of its rich content ecology, LeTV video's excellent experience and massive resources.

LeEco Video 4K source playback

LeTV video provides massive resources, including film, TV series, variety show, music, sports, live broadcast and other channels; In addition, it also provides 4K, 1080P, Dolby and other high-quality content areas, which are exclusive to members. All users who buy TV can enjoy these high-quality resources for free within one and a half years. What the author likes most is the 4K resource zone. The 4K ultra HD blockbuster with the 4K ultra HD large screen is the ultimate experience. Only in this way can the ultra-high configuration of the super TV be brought into play, and the 4K configuration will no longer be worried about becoming idle chicken ribs.

Games: ultimate experience

exceed 4 X55 Super TV, as a large screen TV of the main game, has very rich game resources. It supports many types of games, including action adventure, sports competition, leisure puzzle, family parent-child, flight shooting, online games, etc; The home page is divided into the handle area, the Army Day area, and the chess and card area. The experience of massive game resources with the game handle is also very good. The author has selected a number of games for actual testing. Here are two classic games to fight against landlords and boxers!

Game Test: Boya vs Landlord

Game Test Boxing 97

The attached handle is very good, and the connection mode is very simple. Similar to the Bluetooth mouse, you can install the signal receiver to the U port. During the game experience, the handle connection is stable and the control is smooth; The music key in the middle is not designed reasonably, and it is easy to misoperate during operation. Several times, it is accidentally pressed during playing, resulting in direct shutdown.

The somatosensory game is a major feature of the game zone. It must be fun to match the somatosensory camera and the somatosensory game gun. Unfortunately, the standard configuration is not equipped, so it is impossible to test and display. As a game TV that is claimed to be comparable to the game console, it is also a great pity.

Highlights

one 55 inch 4K ultra clear large screen, supporting HDR display MEMC motion compensation technology; 2、 Harman Carton speaker, ultimate auditory enjoyment; 3、 Mstar top processor, 3G running memory, 32G memory, and smooth operation; 4、 Unique LeEco cloud ecosystem, 16 month super Class members, with all kinds of contents. 5. The game experience is good with the handle and massive game resources.

Insufficient

one . The standard configuration has no base and body sensor camera;   2、 15 second advertising is mandatory after startup;   three . The mouse mode of the remote control is not flexible and perfect enough;   4、 There is a vulnerability in the EUI5.5 system version. The file export cannot be clicked. Occasionally, the system is stuck. The problem disappears after upgrading to 5.8.

letv exceed The 4 X55 super TV, as a 4K 55 inch large screen TV with a list price of 3599, is fashionable and modern in appearance, has an ultra-thin frame, excellent workmanship, strong processor performance, and the ultimate hardware configuration is invincible in TVs at the same price; On the basis of large content, LeTV has built a LeTV cloud ecosystem with rich resources, interconnected content, and the combination of software and hardware. It has also achieved the ultimate in software. Although many aspects are still not perfect and mature, it has been able to ensure that LeTV Super TV stands out in the competition with other hardware manufacturers and captures the hearts of viewers.
