The 45-inch LeTV Super TV (above 4 X55 Curved), which is expected to be sold only in the 517, took nearly a week from order to receipt, probably because it was an evaluation experience machine (it is said to have been produced in volume. There is no difference in the machine.) It shows shipments from Shenzhen warehouse, and SF Express. This is such a big embarrassment. If you go from Shenzhen to Beijing, will it be a long journey?
1, orders to the receiving package, open the box installation experience
After receiving the goods finally assured, music as the super 4 X55 Curved was shipped so large, as shown below. There are also four plastic snaps at the bottom of the inner box. Shunfeng brother told me to find music as the manufacturers to the door to install, they are completely responsible, this advice is also seen at the top of the box, but this little job can not help myself, all their own handle, unpacking, installation, DIY . 
At first glance, it was hard to believe that this was a 55-inch curved TV, an ultra-narrow frame, and a slim body. The outer set of protective foams had withstood the thousands of kilometers of transport trials. At this point, it was still worthwhile. Relieved. 
Bracket installation is the use of manual knob screws, let me think of the current trend of DIY PC chassis design, so that the benefits are obvious, do not need to find a screwdriver everywhere. Details are considered more thoughtful. 
LeTV 4 X55 Curved all the interfaces are arranged in the back and down the left side of the fuselage, I deliberately carefully read, like some often need to plug the interface, such as HDMI, USB, etc. are designed in the side of the fuselage , Even if the TV is fixed on the wall, there is also a certain amount of space into which you can insert and remove USB flash drives and other devices. The bottom-facing interface is generally an interface that normally requires a fixed state, such as RJ45 network port, optical fiber, and so on. I also found that the aircraft also supports MHL and ARC, like some devices that have a digital back-to-back HD audio signal, such as a Philips Sound Bar that I used before, and do not need an additional SPDIF fiber. . 
Actually there was an analog antenna terminal adapter. At first I didn't understand what it was useful for until I plug it in to discover the need for this gadget. Like me because of renting and living, but the landlord did not give a set-top box, usually see live satellite channels (such as Hunan Taiwan and Zhejiang Satellite TV, etc.) will need to use that kind of old coaxial analog antenna, that thing because the transmission is a simulation The signal, so the outer layer of a very hard and thick shielded wire, and can not be bent too much, the adapter in the above figure is very good to avoid the interface is inserted in the bottom of the TV and makes the simulated antenna excessive bending. 
In addition, for old-fashioned set-top boxes or DVDs and other equipment, the TV has to set aside AV analog input ports, equipped with a one-to-two line, such as I bought a bully game machine for nostalgia, so that the analog line can not Inserting a cup on a new TV is still necessary. 
Summary: Music as the super 4 X55 Curved Although the manufacturer proposed to make an appointment to install the door, but if you just use the base bracket, according to the instructions to assemble it is not difficult, because the body is light and heavy, so the body is installed after the base is very stable Don't worry about shaking and tipping. In addition, the fuselage is heavy. To be safe, at least two people should assemble and carry it. Otherwise, it is easy to injure the relatively fragile curved screen.
2, boot the basic operating experience
Connect the power cord and insert the battery into the remote control to turn it on. Here to talk about feelings, the first feeling is "big", I used a 32-inch TV, this time directly up to 55 inches, and instantly feel that I was "small" a lot. The second is “Qingâ€, and the 4K screen is indeed shocking, because this TV description contains a “Contains Startup Advertisementâ€. After the startup, the display of the advertisement screen is very clear, and it can be said to be complete. There is a more important feeling, that is, "not too bent", just when I switched on the station position is relatively close to the screen, this thought for the first time with a curved screen in the heart will not be bent or look at the screen dizzy This feeling is actually a lot of concern, although the screen looks curved, but the display is very balanced, and there is no sense of discomfort. In more professional terms, the curvature of 4000R means that the degree of screen bending is not too “outrageousâ€, like the general living room of about 20 square meters at home, and the viewing distance of 3.5 to 4 meters is the best experience distance. 
This TV directly presented me with a one-year membership, because I already have music as a mobile phone, so the membership period can be superimposed, so that the membership time can be extended to nearly two years. 
After the first power-on, a simple configuration of the LeTV is performed according to the system prompts. This includes registering the LeTV account (entering the mobile phone number and verification code) and the other service deadlines (if any) to which the account is bound. Here comes the remote control experience. Le Super 4 X55 Curved equipped with a "super remote" really is not simple, at first I saw a window on the top of the remote control, that this is just a very simple infrared remote control, the system can actually prompt but also upgrade the remote control! And the remote control uses infrared + Bluetooth dual control. When you start up, you need to use infrared red energy. Turn on the TV, I think this design may be to save power to the remote control. When the TV is in standby, the Bluetooth module of the remote control may be in deep sleep, which can increase the battery life. 
Using the remote control for mouse mode manipulation
When watching TV with analog signals, I was a bit distressed. There are no number buttons on the remote control. For example, Hunan Satellite TV is 4 sets, and Zhejiang Satellite TV is 10 sets. Switching is a little troublesome. Fortunately, manufacturers have thought of this problem, in the upper left corner of the remote control designed a virtual number keys, the operating speed quickly increased, can see LeTV for this remote control is actually a certain amount of effort. Of course, it can also be switched to mouse mode. The remote control has a 3-axis gyroscope that can be turned into an empty mouse to move the mouse pointer with a slight shake of the wrist.
LeTV 4 X55Curved TV users can refer to the tutorial: LeTV 4 X55Curved installation method to install a sofa housekeeper to achieve third-party application extensions. 
Summary: Due to loading the smart system, LeTV 4 X55 Curved boot process is longer than the average TV, and because there are boot ads, about ten seconds, this can not be canceled (the official website purchase page does Clear text descriptions, so you must be a little patient. In addition, the remote control feels more comfortable, the layout is more ergonomic, five-dimensional direction keys can perform most of the operation, and blindness can also be more relaxed. At the bottom of the TV, there is a physical mechanism at the bottom. This is not even true for many brands of smart TVs. In addition, the TV's audio system is also worth mentioning, in the back of the fuselage on both sides have a large-size speaker, a stereo effect, it is said that ultra 4 X55 Curved sound system after a Harman Caton certified three-way design, Support Dolby, DTS advanced audio technology, very rich layered and shocking.
3, network video access speed and program number experience 
For LeTV, the core is the resources and content. Imagine if LeEco is only a manufacturer of hardware, it will not be able to connect with its strategic slogan “ecologyâ€. Therefore, the core content of LeTV is video resources. For those who bought LeTV Super TV or LeTV Super Mobile Phone, one of the benefits to enjoy is LeTV. You can even purchase LeTV members for many years to achieve the effect of “zero dollar purchaseâ€. This is very meaningful today when intellectual property awareness has not become mainstream ideology.
It is believed that many people have this kind of entangling mentality. Because we used to use the free stuff before, just like I used to download Thunderbolt and other download software to download all kinds of big movies, episodes, and even download the classic movies, series collections, dials, but in fact most I haven't seen it ever since, especially with the hard disk space and CDs. Nowadays more and more people are accustomed to, and they like to watch videos and movies online. For online movies, the free videos of video websites are not very old, they need to endure ads for several minutes and encounter the Internet. In a bad situation, you have to re-appreciate the annoying ads once again, and some video sites cost you money to buy members. The video resolution is not enough, the graininess is serious, and even online video is not smooth, excluding home network speed. Problems, as well as server speed issues. More often than not, when you bought a member of the A-Video site, the video that you wanted to watch was only visible on the C site because of copyright issues, which seriously hampered the enthusiasm.
From this point of view, after my comparison found that LeTV online resources are absolutely the most abundant, and also the smoothest clarity I have ever used. For example, the hottest film mermaids and Oscars wilderness hunters of the previous days can be directly watched on Letv TV (if you are logged in), the episode is new, and the number is large. In addition, music is the best resource for sports programs, and various online live sports events, victory over CCTV5, look and know. 
Summary: LeTV 4 X55 Curved equipped with music video resources really is a surprise, both from the video loading speed or video quality point of view, are superior, especially the recent increasingly strict radio and television policy, making LeTV's legitimate massive video resources to People have eaten a reassuring pill so that they will not be able to use all the videos and applications after the TV has been bought for a few months. (I bought a HD box before, and I promised to watch videos for many years or even lifetimes before I bought it.) It will be finished in a few weeks...). Another advantage is that movies are updated quickly. For example, mermaids and wilderness hunters can watch for free in the offline process. Even some movies that LeTV has invested in copyright can watch the movie simultaneously. (I remember the previous nine. The layer demon tower is), plus last year at the end of last year, LeTV signed an exclusive contract with the Premier League and recently won the copyright of the Super League. It seems that the gold content of LeTV members is really attractive.
4, EUI's ease of use experience
From LeEr Super Mobile Phone to LeTV Super TV, EUI, as the core of LeSco Ecology, acts as a bridge and an infrastructure, and a mobile phone or a smart TV can make people love and spread their reputation, even to a certain extent. Dependency is not the key, so the fluency and ease of use of the operating system are very important. 
The LeTV 4 X55 Curved operating system uses an Android-based EUI5.8 operating system. The homepage integrates the synchronized cinematic desktop and LIVE desktop to form the effect of multiple TV walls. At the same time, children's desktops and game desktops are classified more scientifically. It is easy to understand and use. For example, on the homepage, all icons use a relatively large box-like style to facilitate remote control operation. The main menu at the top of the screen, you can directly through the remote control left and right buttons to quickly move screen operation, the left side is the signal source, you can quickly and easily call-out set-top boxes and other live TV programs. The second setting becomes a search button to facilitate retrieval of video resources.
In addition, the search box for the virtual keyboard settings, EUI is not rigid in accordance with the traditional virtual keyboard style design, but on the left side of the screen through the A~Z nine-square grid arrangement for input, I think this input is more efficient, For example, I enter ZPW, which is an abbreviation for House of Cards. The right side of the screen directly gives the most qualified search results, and the speed is very fast. The quicker way is to search by voice. Press the voice recognition button on the remote control directly. Originally I thought that the voice recognition was a TV search. Every time it was a loud "make the TV hear", and later I found the original remote control itself. There is a microphone, directly to the remote control for voice input just fine, there is a very convenient feeling of wood?
Press the "Le" button on the remote control, you can press a shortcut menu, such as a key to watch TV, movies, games, screenshots, off the screen and other operations, you can also customize the commonly used program here, removed again To go the traditional way: the main menu - the program - to find procedures such as the tedious way, it seems that EUI engineers have carried out a very large number of user-centered thinking and design. 
5, local video, gaming experience
LeTV 4 X55 Curved gives the powerful features of domestic smart TVs in the local video. The basic video format takes all, except for several wmv formats, such as avi, mp4, flv, rmvb, mkv, etc. Can take all, and 4K video decoding is a second open, drag free pressure, once again reflects the good decoding capabilities. On the hardware, the TV has a new 64-bit TV processor: the Mstar 6A938. Its A72 architecture CPU performance increased by 86%, the flagship GPU Mali T820 performance by 50%, even 4K games can easily deal with, because the Core Turbo true multi-core drive engine for two A72 and two A53 quad core.LITTLE architecture processing Faster and more efficient. The new flagship GPU - Mali T820 up to 650Mhz, triangle fill rate is 400MTri / s, pixel fill rate is 2.6G pix / s, support for Open GL ES 3.1, through the large screen to watch high-definition video does not get stuck, play 4K games Smoother interaction.
In terms of games, because there are many games that require the use of dedicated gaming devices, such as LeTV King and LeTV, but I have a chicken game controller at my fingertips, and I just enjoy watching TV with Bluetooth. After the drive-free connection can be successful. Revisit the childhood game Snowman Brothers and have fun without any delay. 
6, curved screen viewing experience
It is not important not to say that it is not important to put the sensation of the curved screen in the end, because it is the first time I have used a curved screen TV/display. As the commentary said at the beginning, before lighting up the screen, I was even worried that the curved screen would not look dizzy or the screen would be distorted when it was too long. In fact, I was worried about it. After a week of experience, I even thought that when I looked straight at the screen, I felt that the corner was too straight. I was not ergonomic and I was not used to it. Curved screens, especially curved screen televisions with large curvature, may have a little “ring curtain†cinematic feeling if they are watched in a suitable location (I call it “the emperor bitâ€). In a stylish word, It's very immersive, especially with the super 4 X55 Curved sound system to see the wilderness hunters, there really is a theater-level effect, shocking feeling. More feelings are not suitable to describe in more languages. If you really go to watch it, you may understand. 
The room space is relatively small, the actual viewing distance does not reach the official recommendations of 4 meters, although the screen can still feel the feeling of a curved screen, but from the pure viewing experience is basically no different, can be said Whether it is the exquisiteness of the picture or the sensation of sound effects, it is truly a perfect experience. To say that the only downside is that the real 4k source is relatively small. At present, if you want to experience a pure 4k high bit rate movie movie, you still have to download it from a professional forum. The highest quality of online video is 1080p. For LeTV 4 X55 Curved, it seems to be a little overkill. However, it is believed that in the future, the construction of resources and the acceleration of network bandwidth will continue to progress. It should not be difficult to watch high-rate 4K video directly online in the near future. 
7. Summary
First of all, thanks to the micro-blog activity of LeTV Mall, so that I can experience this legendary "artifact" in advance. This music as Super 4 X55 Curved from the receipt of the goods, before and after also spent a week, and still some I feel like I was too small in a small rental house. The TV is too big, but it is still curved. Will it look like halo deformation? In fact, it is this feeling: After you have used the large-screen, high-definition 4k effect, Going to see other TVs is completely gone. At the same time, LeTV's EUI with humanized remote control design, whether it is games or video, can give people a very comfortable feeling, I feel that some operations on the remote control, there is a "If you press this button will do the kind The operation is good, and the result is that the feeling of designing such as the exhalation design of the menu key and the operation of moving the left and right keys across the screen of the main menu is more efficient than the television box I have used before. In addition, the benefits of LeTV membership are also found to be very cool, such as movies synchronized with the cinema (maybe most of the time after the downline, but also very soon), as well as a very fast update of the US drama, and Smooth high-definition online resources, no longer need to change the dozens of channel remotes in exchange for what you do not know. However, since it is a summary, to say that fly in the ointment, it may also be the problem of boot advertising mentioned in the previous article, which lasted more than ten seconds, and sometimes it was quite maddening.
The shock of the surface, music as super 4 X55 Curved evaluation
Do you know the world of Tyrant? As the fastest-growing Internet company in China (at least I think so), LeTV in less than a year, from 0 to close to 6 million, which is Lexus mobile phone sales from the creation of the brand until now. Even the original Wukesong Sports Center was regarded as a music and sports ecology center by LeTV, and not only mobile phones, like television, film and television, VR, bicycles, and even super cars, Leshi as all involved, but also do a good job, you must not Do not say, this is really a super super tyrant, a promising company! At the same time, with the increasing influence of LeTV's influence and product popularity, I now buy mobile phones and even TVs, and the leading brands have taken music into consideration. The landlord has also recently been fortunate to receive an experience machine provided by LeTV as part of LeTV's official Weibo event (@LeTV).
