The idea of buying a TV has been around for a long time. As a digital enthusiast, he will definitely choose a smart TV, so the brand is between Xiaomi and LeEco. Originally, I prefer Xiaomi, but this year four hundred and fourteen On LeTV Hardware Free Day, LeTV launched the activity of buying TV to give away members. At the same time, the distribution scope of Xiaomi TV still did not cover Ningxia, so it bought LeTV's S50 Air 2D I have been using this version for two months now, so I can share my own experience.
One word for appearance: ordinary
I bought LeEco S50 Air 2D Version, the screen is fifty Inch 1080P Full HD screen, excluding the length and width of the base 111.74cm*65.27cm In fact, this TV has been released for more than two years, and it has been officially launched for more than one and a half years. Therefore, it also adopts the black design of the plastic body, which is also the design style of the traditional TV. At present, its appearance has fallen behind. If there is a high requirement for TV's appearance, then the following text will not be read, because the appearance will not pass.
S50 Has adopted a narrow border design. The narrowest border is 4.5mm , I feel a little borderless when I sit on the sofa. The screen and the frame are very solid. You can't see the gap between the screen and the frame when you press it with your hand.
S50 Frontal letv The indicator light will give off a faint light after power on, indicating that the TV has been powered on, and the light from turning on the TV will turn on as a whole. This design looks cool in the daytime, but if you turn off the light at night, it will distract you from watching videos.
S50 The thickness of the upper half is 1.94cm, The lower part is 4.3cm, The thickness of the upper part is only two keys wide.
There is a physical control button for the TV on the right side of the back of the fuselage, which should be used as a backup when the remote control cannot be found.
S50 The design and workmanship of the back are also relatively ordinary, including the interface one Optical fiber interface one One coaxial cable interface, one network cable interface one individual VGA Interface one Headphone connectors two individual USB2.0 Interface one individual USB3.0 Interface one individual SD Card slot, three individual HDMI1.3 Standard interface, where one individual HDMI The interface also supports MHL , enough for normal use.
I am right S50 The biggest dissatisfaction with the workmanship is that the screws are arranged outside without any regularity. I counted the number of screws on the TV frame thirty Screws on the back thirty-six These screws give people a rough feeling.
The two TV supports on the base are metal, and the bottom arc is plastic. When you buy this base, you can get it as a free gift. If you need a rack, you need to buy it separately.
The whole base is not very stable. If you gently shake it with your hand, it will have a very obvious shaking feeling, so try to place it against the wall at home.
summary : LeEco S50 Air 2D The appearance design and workmanship of the TV version is the same as that of the Internet TV two years ago when it was just launched. There is no problem in normal use, but it is obviously different from the current smart TV with all metal bodies.
One word on the screen: pleasing
S50 Using fifty inch 1080P Screen, LED Backlight source, 300cd/m2 Of the whole machine brightness, not supported 3D and 4K . When I bought it, I felt that fifty Inch selection 4K It doesn't work, but the screen can't reach 4K Resolution, the processor must be able to decode 4K The reason will be mentioned later.
S50 The color saturation of the screen display is relatively high, slightly cold overall, and the overall display effect is somewhat similar to Samsung AMOLED The effect of the screen will be more pleasing when watching the video.
These pictures fully illustrate S50 In the saturated color display mode, the color is more pleasing than the real color.
The layering of the screen is also pretty good two thousand and three hundred It is of high quality in price.
Summary: S50 The overall quality of this screen is very good, that is fifty Inches are still a little small. Smart TVs are now the same as smart phones. The large screen of the previous two years has now become a small screen. It is recommended that you buy a large size TV as much as possible.
One word of system: chaos
During these days of use, LeTV's system gave me the greatest feeling of chaos. The logic of the whole operation was not unified and there was no clear level.
LeEco's operating interface uses the top to subdivide columns. With signal source LIVE , sports, games, applications, search and other subdivisions can be switched left and right through the remote control. At first glance, such operation logic is clear, but because the content presented on each page is limited, the problem of logic confusion arises when you need to click for further details.
Notice that after clicking "Video Classification" to enter the secondary menu, the column breakdown has moved from the top of the primary menu to the bottom of the secondary menu. In the secondary menu, each content is classified by a box. "TV drama", "movie" and "LeEco children" are color blocks, and the rest are black and gray background color with white characters. However, "CSL", "variety art" and "education" have deepened the color of these three blocks. I don't know why they have deepened the color of these three blocks, I felt very confused.
If you haven't forgotten, you should remember that there are special Live Subdivision projects, now entering the second level, are simple and appear again Live Subdivided items are the same as the first level menu. And most of the content of the live broadcast is sports, so it is more appropriate to put it in the sports column.
What I don't understand most is that when returning from the secondary menu to the primary menu, instead of returning directly, the prompt "Exit LeEco Video?" appears. It feels like a LeEco video has been installed on the TV App , rather than using LeTV, the sense of separation is very strong.
After complaining about the logic, let's say a more intimate design. It has a time management function in LeTV's children's channel. It can set the cumulative broadcast time every day and the maximum broadcast time for a single time. The bear children at home can watch TV through this control.
LeTV Live The functions are divided into film, TV series, CSL, sports, children, variety show and other content segments, and each station is numbered. such as forty-seven Channel is car channel fifty Channel is an advertising channel, similar to watching TV through a set-top box five Channel is CCTV5 、 thirty-three Channel is the same feeling as Hunan Satellite TV, simulating the usage of a traditional TV. Mom is right about this Live The interface adapts quickly, probably because the simulation is more like the control of traditional TV.
Finally, a controversial function is introduced. If a video cannot be searched on LeTV, it will prompt you to go to the corresponding website. If you click it, you will jump to the corresponding video website through the browser. Although this practice is convenient for users, it seems that this method of jumping through the browser is prohibited by SARFT, and LeTV should be operating against the rules.
One word of live broadcast: clear
One of the important reasons why I choose LeTV is that LeTV has rich sports copyright, so the most important thing for live video is the definition of sports video. For example, for Premier League live broadcast, menu options include opening and closing bullet screen, video definition, and video size. Among the options of definition, non members can select "Ultra clear" mode at most VIP Members can choose 1080P Clarity of.
But the Premier League“ 1080P ”There is no obvious difference in appearance between live broadcast and CSL's "ultra clear" live broadcast. In fact, if we want to realize the real 1080P Live broadcast is a huge test for LeEco's server and bandwidth, and the cost will be very high. At present, it is difficult to really implement it.
In the aspect of online video broadcast, the variety show can choose the "ultra clear" mode at most. Its own color display is full of colors, which is more pleasing to the eye. However, under this blue screen, I feel that the overall feeling is too saturated, and it is not natural and comfortable to look at.
Pay attention to the blue-green transition on the left side of this photo. It can be seen that the color transition is not natural enough, which is the reason for the low bit rate of live online video.
Compared with variety shows, LeTV has the highest choice of movie resources 1080P , the actual appearance is online 1080P Although the video does not have the high bit rate that we download through the network 1080P Good effect, but there should be no dispute that the definition belongs to the first echelon in online video. On the issue of definition, I specifically checked on the Internet and found that there are many channels of LeTV, but the definition of video resources in LeTV is almost high.
In addition to online viewing, S50 It also supports the download of some videos. The broadband at home is low and you want to watch them 1080P The friend machine of clear online video can download and watch the video resources directly. However, whether it can be downloaded depends on the copyright. Not every movie or TV play can be downloaded.
Play local video: sorry
Actual test S50 Local video playback capability, high bit rate 720P Video and most formats 1080P All videos can be played perfectly.
For multi track video, multiple tracks can be identified smoothly, and the switching process is basically smooth.
Unfortunately, for high bit rate TS format 1080P Video, S50 Will not play smoothly. This video is downloaded by Phoenix Satellite TV sixty Anniversary National Day parade, size: 27G , on 1080P The video has a high bit rate, S50 Just stay in the circle interface, unable to play normally, but Xiaomi box three The enhanced version can play smoothly. I test and S50 Use the same one Mstar6A918 Millet TV with chips two , Xiaomi TV two Can play smoothly, including 4K All videos, including video, also support 3D . Since the same chip is used, S50 Its video decoding capability is not comparable to that of Xiaomi with the same chip three It can only be said that LeEco did not seriously optimize this chip for cost control.
When I bought this TV, I thought fifty Inch up 4K It is unnecessary, 1080P Resolution is enough. But I just paid attention to the screen. I didn't know whether I could decode it 4K I feel the problem of the video when I use it, even though 4K Video placement 1080P The resolution of the TV can also be felt to improve the definition. It is recommended that friends who buy TV in the future must choose support 4K Video decoding, even if the screen resolution is not 4K 。
Summary: LeEco S50 Air 2D During the use of the version, I was disappointed with the overall workmanship of the TV, but I was quite satisfied with the richness and clarity of LeTV video content in use. After all, the most important function of buying TV is watching video.
advantage : Rich video content and high definition.
Disadvantages:
one Average appearance and rough workmanship;
two , Operation UI Chaotic hierarchy, not supported 4K decode.
Purchase suggestions: Although LeTV's marketing method of buying TV sets from members has been criticized by friends, almost all Internet TVs that do not buy members now not only need to see advertisements, but also have limitations on definition. To have a good experience, you must buy members. During the period of experience, LeTV's membership experience was good. It is suggested that friends who buy LeTV TV should try to buy it when LeTV is doing activities, otherwise it will be a year four hundred and ninety The annual fee of RMB yuan for super film and television members is quite expensive. As for this S50 Air 2D For the version, if the budget is sufficient, try to buy LeTV's latest TV, and the design and workmanship will be greatly improved. Of course, if the budget is limited or you don't care much about the design, you can still consider buying the TV given by members.
