What is the most popular TV industry in 2016? Then you have to know these keywords: HDR, surface, processor, content, free! On March 30, LeTV's "Assembly" new product conference in Beijing, based on the globally-opened closed-loop LeTV ecosystem, TCL launched the world's first Internet HDR surface 4K eco-TV 4th generation Super TV Super 4 X55 Curved almost all of the above content, once again staged a "subversion never-ending" story. Here we will bring LeTV 4 X55 Curved experience text for everyone.
The surface is very different
Exterior
In the purchase of television, many people like the bigger the better, always feel that the bigger the screen is, the better the perception is. Actually, there is data that the 90% of the commercial housing living room width is between 3.5 meters to 3.8 meters. If you choose The 70-inch TV was watched at this distance and the experience was very poor. Maybe it's because I'm not quite comfortable with this range. It's still a matter of opinion to choose size. (I personally believe that the 55-inch TV is the best size for the viewing experience)
The popularity of Qu Ping is said to be market demand. It is better to say that manufacturers have guided market demand, because there is no difference between the screen's actual effect and technical content and the non-curved screen. From the perspective of perception, Qu Ping does bring about improvement. , But how much pleasure is increased depends on personal preference. I believe that for most people, this increase will not exceed 20%. The difference between the price difference from Pingping to Quping and the perception is consistent with the purchase. The actual needs of the people.
HDR:
Using HDR technology in TVs, popularly speaking, it can achieve two functions. First, it allows you to see the details of the shadows. The second is to show more real shocking effects in high-light scenes. For example, the character is lying on the beach by the sea, When the sun shines into the eye with an eye open, or when the character is standing on the ground of a desolate dark planet and watching the scene where the searchlight lands directly on him when the aircraft carrier lands, HDR can make that feeling even more shocking.
To realize the above two functions of HDR, let's not mention the source of the film. Currently, it is mainly achieved through three technologies:
The first is that TV software supports HDR functions and can also be understood as supporting HDR decoding;
The second is meticulous division of light control, which is to divide the entire television into several regions on average and realize the function of different brightness in different regions;
Third, the peak brightness is high enough. The brightness of commercially available non-HDR ordinary LCD TVs will not exceed 150 nits. However, in order to realize the sensation of lighting and shock, the peak brightness needs to be at least doubled to provide sufficient results. The 4 X55 Curved Curved Screen offers a brightness of 250 nits.
Summary: This 55-inch curved screen is the reason why I chose LeTV. Moreover, LeTV 4 X55 Curved has added HDR effect. In the case that the price is not much higher, I believe that choosing LeTV 4 X55 Curved is the best.
The most amazing place on the screen
The most important and basic aspect of a TV is the accuracy of color. For this purpose, computers and color correction instruments are used to obtain data, but color correction is not performed. The LeTV Ultra 4 X55 Curved surface is only a monitor for external playback devices. When an external storage device or video is played over a network cable, the LeTV Ultra 4 X55 Curved surfaces will use the built-in playback module, which means that the software adjustment differences It will only be reflected on the computer. The playback of video and picture effects will be inconsistent with the TV's built-in software.
Will HDR be effective for video and pictures? How much is the effect improved? Is HDR really chicken or practical? Can HDR only support built-in playback software or external video signals? In order to solve these doubts, I use the computer to connect music as super 4 X55 Curved, mobile hard disk access to X55 two ways, TV screen standard mode, respectively, to play pictures (JPG format 4K resolution), US drama (Song of Ice and Fire S06E07 MKV format 3.3G), 1080P HD movie (terminator 5MKV format 8.74G), 4K HDR video (HDR demo slice TS format 762M), for confirmation.
When I looked at the color data, I said that the color temperature of the LeTV 4 X55 Curved screen is high. It looks particularly noticeable in this picture. From the screen shot, I can only see the 51st frame, but I can actually see it with the naked eye. 34 cells.
Aside from the color temperature, brightness and dark layers are quite clear
This picture forgets the text on the right side of P, and everyone will click on it. The sequence is the same.
Color side view this, you can see TV than the computer in the color performance of some brighter, such as the nine balls in the upper right corner of the brown ball, the TV is obviously a bit lighter, in fact, the TV is slightly too bright.
The problem with the leaves of this picture TV has not changed. It is still a little over the brightness. The color of the computer is also more concentrated. Pay attention to the shiny leaves on the upper right corner. The brightness of the TV is over, but fortunately the details are still identifiable.
The castle can be seen in this picture, the TV is very well controlled, the upper right corner of the bright place does not appear excessive brightness, and the lower right corner of the stone and leaves are clearly visible on the TV side, the computer has not seen the details of the stones and leaves .
In this traditional drama figure, highlights such as the crown of a person's head worn on the local television lost details and the computer retained them. Apart from that, the colors were quite the same, but the TV in the far left corner of the house was more clear.
Woman and dog This picture, the face of the face of the person's face The details of the computer side to lose some, but the dog's hair texture, but also the TV is more clear.
The arm of the wedding woman's figure will be the contrast point of the two kinds of play ends, as well as the texture details of the model hair, and the specific performance is the same as the previous ones.
Contrast picture summary: It is impossible to judge whether the internal software and external player can use the HDR function in picture viewing, because the difference is only a slight difference in the overall brightness. Friends who like rich and solemn colors will prefer the effects of the computer, like bright and clear. The friends of color will prefer the effects of the TV, but the accuracy of the two colors is almost the same. The difference can only be said to have nothing to do with HDR.
To be honest, I was a bit disappointed when I was testing here. Did HDR really just a PPT effect? ​​Then I went to a video test.
At present, video resources are almost 100% non-HDR resources. How effective the HDR function can play on these resources determines whether the HDR function is a chicken or chicken leg.
Because TV-based playback pauses cannot keep the picture pure, you can only see pictures with a pause effect, but it does not affect the effect of contrast.
First measured is the Song of Ice and Fire S06E07 MKV format 3.3G
The first picture can surprise people. First of all, it is clear that HDR only supports in-camera software playback and does not support external player input video. Secondly, the HDR effect is very obvious. Note the right-most soldier, the middle bear. The door below the paintings, the effect of the winter sun, and the bright and dark parts of the front two clothes, the HDR function is very good to brighten the highlights, and should not be bright Some darkness.
The next test is Terminator 5MKV format 8.74G
The middle of the sniper slamming the texture around the muzzle is very clear.
Lee Byung-soo's forehead's bean pit is clearly visible, and the layering is obvious...
In this picture, the sun is 45 degrees ahead, close to the backlight effect, HDR achieves a sense of backlighting, but the water surface details are lost ~
Next is the 4K DHRHD R demo TS format 762M video test.
Everybody, please fasten the seat belts~
summary:
In terms of pictures, the HDR function basically does not provide any improvement effect; however, in the ordinary video, this HDR function can bring about a large improvement in picture quality, especially in the details and level of darkness, and there are also good improvements in color. The effect, but on a bright screen, there may be situations where the light is too bright and the details are lost, and a slight color cast will appear as a whole.
It is worth mentioning that the changes that HDR encoded video brings after HDR decoding are enormous, even if there are problems with the picture being too bright, but the visual impact shock will make you think that those are not problems. What I did was wait for more HDR video screens to appear.
The best system experience
The LeTV 4 X55 Curved screen is based on Aurora's flagship Mstar6A938. The Ann TV version can reach 46,000 points. The performance is good, and it is fast enough to use. Although the Super 4 MAX70 uses 810 chips to score close to 83,000 points, LeTV 4 X55 Curved curved screen does not make much difference with Super 4 MAX70, perhaps to the level of the chip, but also affect the speed of the read network data two or three seconds delay, rather than system performance.
There are good hardware and display effects, of course, with a rich content resources, the combination of software and hardware can play the greatest value of a TV. In terms of content, it is recommended to install a sofa butler - the sofa butler is a third-party app store designed specifically for smart TVs, Android box users, carefully providing television, box users with high-quality television exclusive version of the application, including with live Or on-demand video and audio and video software, various types of recreational competitive video game software and daily office entertainment management system management tools. LeTV Super 4 series installation method
Before touching LeSport's resource system, I had access to two other online TV branding systems, one of which was familiar with coarse grains. After installing some apps to make up for resource acquisition channels, I felt that it was still quite good. Later, I contacted them. After seeing the system as music, only know what the resources like the sea.
The LeTV system has a total of 8 sections. Apart from the impractical sections such as shopping, other sections are more practical and have targeted audiences, such as sports and children. In the settings, the system can set the content is very simple, perhaps this is LeTV's confidence, right? Fortunately, the color settings provide four basic options for brightness, color, sharpness, and dynamics. Although they are still not rich enough, they can already meet basic adjustments.
Some of the functions of different sections need to be installed by App. Fortunately, the applications directly recommended by the section are excellent. For example, if the sports section has a thin icon that is a lightning bolt, you will find that you can choose to install the Keep TV version first. It's not a good idea to do HIIT on a big screen.
LIVE is a major feature of LeTV's resource system. There are a total of 268 stations. The system classification is very detailed. Even the badminton broadcasts that are rarely seen in other resource platforms are available. Although it is in English, the richness of resources can be seen. In the live broadcast, you can also use the PIP function to watch two stations at the same time. It basically meets the needs of most people in terms of resources. The only regret is that there is no live broadcast by the CCTV. Of course, this is not a problem with LeTV, but it is to blame the General Administration of Light.
Voice buttons on the remote control, long read the title can be used to search the film source platform, voice recognition rate is high, you should also use the signal fly voice system, this advantage is that you no longer need to enter the way to find It is very convenient. In addition, LeTV's resource library can be described as horror. Various popular resources are basically available.
The LeTV video of the application section is similar to the video portals of other manufacturers. The resources provided therein are the same as the searched out resources. Because of the convenience of searching, LeTV also does not provide the function of setting the default startup music video, and the direct voice search can be started. Satisfy most people.
Music play is a function of unexpected accidents. First, there is an accident specifically this function, and second, accidental layout is done well. Unfortunately, music as the super 4 X55 Curved curved screen does not come standard with music as the external audio, in addition Le Le actually built a reader , but also normal Internet access, I seem to remember that the requirements of the Bureau of Lightning can not be installed ...
In addition, in use, found LeTV system has many very detailed humane places, such as allowing to set the default layout of the boot; insert the U disk window automatically pop up to see if the new device is immediately viewed; after copying things in the TV memory, it will automatically pop up external The memory stick gives the user the option to paste; most of the interface can directly press the voice key to search and jump. The optimization of these details, after using the Levision system after having contacted other systems, will have a deep feeling. Even the coarse grain of UI is not as comfortable as the LeTV system on the TV system.
Resources:
LeTV's resources can be described in terms of horror. In addition to CCTV's TV station, you can see almost all videos that can be seen on the entire domestic network, plus more than 200 live channels. Dramas and exclusive TV shows have all opened several levels of friendship. Before using other manufacturers' systems, each time they bothered to install various apps to increase resource coverage, and it was totally unnecessary for LeTV to find them. Of course, if you have special app preferences, you can also install them freely. The system did not do it. Any restrictions.
Summary: The understanding of the Android system, from the beginning of the pursuit of hardware to the human nature of the software, the pursuit of comfort, music system in this regard can be said to come from behind, and slowly to the extreme, I vaguely remember music as the first The system that was used to replace the product really made people think of TVs. The current LeTV system has surpassed other friendly companies in ease of use and comfort. On the first day of the TV installation, I discovered that my 3-year-old daughter could actually turn on the TV and find the cartoon. At the end of the day, I was amazed. Later, I discovered that the LeTV system has been used for 35 minutes. Afterwards, you can realize the fine-tuning of the festival. The thrill of reaching out for a drink, hungry, and the pleasure of reaching out to bread are deep in my heart. When testing other TVs before, all kinds of tests need to keep pressing the remote controller. The total feeling is that the remote controller must be hung up. LeTV is very simple. A voice key implements a large number of human-machine interaction functions and can realize voice. Searching for tablets, next episodes, sharpness options, screenshots, weather checking, etc. If you are bored to hold down the voice key to shut down, it can also be done with ease and ease.
to sum up
As mentioned before, even if you did not experience the product, the curved surface screen of LeTV 4 X55 Curved has attracted me deeply, coupled with the use of my personal favorite TV size, which made me more firmly believe in the purchase. After experiencing the product, I experienced the test. Although there are some flaws, most of them feel amazing to me. In 2016, this "curved" battlefield, LeTV took its first steps, and this The "first step" performed very well. We have reason to believe that in time, domestically produced TV will reach the front of the world.
The surface is very different

HDR:
The picture above shows the HDR comparison
In terms of photography, HDR technology can enhance the contrast of the screen, allowing the original dark, lacking layered images to be displayed in front of you more vividly, purely and truly. Using HDR technology in TVs, popularly speaking, it can achieve two functions. First, it allows you to see the details of the shadows. The second is to show more real shocking effects in high-light scenes. For example, the character is lying on the beach by the sea, When the sun shines into the eye with an eye open, or when the character is standing on the ground of a desolate dark planet and watching the scene where the searchlight lands directly on him when the aircraft carrier lands, HDR can make that feeling even more shocking.

The shocking effects of HDR-encoded video really frightened me. HDR-encoded video played without the kind of color cast and highlight detail that HDR optimizes for normal video, even if the HDR encoded video is too bright. The problem, but when you compare the computer with no HDR decoding, I believe that few people can resist the temptation of HDR.
summary:
In terms of pictures, the HDR function basically does not provide any improvement effect; however, in the ordinary video, this HDR function can bring about a large improvement in picture quality, especially in the details and level of darkness, and there are also good improvements in color.

to sum up
The handheld addresser is used to program the address of the monitoring module offline. When in use, connect the two output wires of the handheld encoder to the communication bus terminal (terminal label 1, 2) of the monitoring module, turn on the black power switch on the right side upwards, and press "ten Add", [Subtract ten", [Add one place" and [Subtract one place" to program the address.
