In many people's impressions, curved TVs are still high-end playthings, and the price of 230,000 to 30,000 yuan is simply “bearableâ€. Moreover, the real imaging effect of the curved TV, whether the system is in perfect match with the hardware, etc., have yet to be questioned. Then is the surface TV really "only a long-term view, not to play?"
Do not ask me the price, because now they have not said!
The bracket is tucked into the bottom and fixed with two screws. Although it looks slender, it is actually very stable. By the way, after installing the base, the weight of the whole machine is a little more than 32Kg.
Hisense K720U is 1.45m long and 0.9m high (including a pedestal). You can get both ends with almost full stretch of your arms. Intuitive comparison, this TV can cover the area of ​​4 40-inch TVs.
Of course, the biggest selling point of this TV is the curved screen, which adopts the 4000R gold curvature of the mainstream of the industry. R in 4000R refers to the radius of curvature, and 4000 refers to 4000mm. In other words, the curvature of Hisense's TV is the same as the arc on the 4 meter radius.
The larger the size means that the thickness of the fuselage is more difficult to control. The top of the Hisense K720U is more than 7cm thick at the center, but the edge of the metal frame is very narrow, only about 1.6cm, the whole machine naturally presents a "first month" shape.
It is worth mentioning that the Hisense K720U not only has a very narrow side frame, but also has a frontal panel frame that is very awesome, and it can hardly see the inner frame, which is much better than some 40-inch smart TVs.
Come to a side face, because the four speakers are at the bottom, so they are thicker.
In terms of details, Hisense K720U uses an alloy frame, which looks like a kind of brushed metal, but it is very smooth when touched.
The base is a one-piece design consisting of two different textures of metal, the two feet are very smooth, and the front crossbar is finely matte.
The lower left corner of the TV is the indicator light and remote control code identification. It is necessary to place the remote control within 10cm and long press for 3 seconds to match. In the lower right corner, there is a physical switch button just below the corresponding mark.
The entire back has a large number of heat-dissipation holes, the power cord is detachable from the TV (the interface is on the left), and a large number of interfaces are centrally located.
Hisense K720U provides HDMI 2.0x1, HDMI 1.4x2, a set of AV interfaces, USB 3.0x1, USB 2.0x2, as well as network port, cable TV interface (provided adapter). In addition, Micro SD card slots and PCMCIA card slots are also available.
It should be noted that the TV's power supply interface is relatively tight, and it requires a large amount of force to insert it when it is inserted, otherwise it is easy to make contact with the surface.
With regard to this TV, what people are most concerned about is the quality of the display quality. How much is the surface quality of the curved screen improved? Will it be deformed? We will look at the actual picture in the next chapter.
When we talk about curved television, we all have a scene in our minds that is “full-wrapped,†that is, no matter how you turn your head, you can feel a full picture that hits the eyeball. Because according to the general understanding, the curved screen will form an angle of envelopment towards the viewer, and better viewing effects can be obtained from both edges of the screen. This means that the curved TV can further enhance the viewing angle and provide a wider image.
The shooting position is about 4 meters from the TV. From the above figure, the curved screen can really bring more depth to the screen. When used to watch 4K ultra-high-definition pictures and videos, it has more visual impact than ordinary flat-screen TVs.
However, everything has limitations. The above is when watching at a close distance. If the distance reaches 5 or 6 meters (exceeding the radius of curvature), then the difference between actual viewing and flat-screen TV will be minimal.
On the other hand, the resolution of the picture has more influence on the viewing effect. If you look at the 1080P picture on the curved TV, it is obviously not as good as watching the 4K picture on the flat TV.
In addition, many people have heard that curved television has an “emperorâ€, which is the center of TV, and only the place can be seen most clearly. This can be sure, certain and sure to tell everyone: Do not worry about it!
As mentioned earlier, curved TV has a better viewing angle, and there is no obvious difference between several tens of degrees on the side. Of course, the middle position is still decisively left to his wife and adults.
The following is the effect under the fluorescent lamp at night. When the ambient light is weakened (compared with daylight), the display effect of the picture is better:
Overall, Hisense K720U's screen saturation is very good, with a color gamut of 140%. This is mainly due to its own "bright color enhancement technology." A separate color matching parametric model can be established for different products and adaptive color Processing, the display of the color will be more delicate.
Actually, this is indeed the case. When a picture with a very dark background is displayed, it is almost completely dark, and the subject is “flight†and above the picture.
The first appearance is "4K TV resolution test chart"
This picture can be accurately identified for 1080P Full HD and 4K HD display, 4K display is easy to see the scale indicated by the red arrow, and 1080P as long as you can see the blue scale even if basically qualified.
The second is a 4K TV color performance and visual angle test chart
As the name suggests, this picture can directly see the monitor's color is not significantly shifted, the viewing angle is not a small problem.
Color performance
The third picture is 4K TV tone level restoration test chart
Finally, to compare it with the iPhone 6 (color gamut 72%), it is clear that the use of the two is very different, TV wins in the color gamut.
Hisense K720U is not only a curved TV, but also a smart TV, while watching live cable broadcast, but also supports watching online video, playing games and mobile phone interconnection and so on.
It is equipped with the latest VIDAA 3.0 system (based on Android 4.4.3), this system was just released yesterday, claiming that the speed has been greatly improved compared to the previous generation, such as the most common switching action takes only 0.1 seconds. Of course, whether or not the system works well depends on whether the overall interaction is smooth, whether the interface is beautiful, and so on. Let's take a look.
From a performance point of view, the individual modules like "Game Center" and "Application Center" all require a certain start-up time of 1 or 2 seconds when they are turned on. However, if it has been started once, it will be very fast when it is switched again. The official 0.1 seconds of switching is not unreasonable.
For smart TVs, the “video†section is the one most commonly used by people. The Hisense K720U uses the video resources of China TV, which can be searched based on type, time, and region, and supports direct search.
Regarding the number of resources of China, we have seen many times on Ali's Lynx box, and the richness of film sources is still OK, but copyright consciousness seems to have been greatly strengthened recently. Many films can only look for 5 minutes. If you want to see the whole film, you need to pay 3-5 yuan. This includes many films that have been released for a long time, including speed and passion 5 speed and passion 6 interplanetary moving through the maze and so on.
Although Alipay Express Payment is accessed, it only takes a sweep to make payments, but it is acceptable once or twice. If you watch a movie, it will be a big spending. If you can open a monthly subscription service, you will be able to watch all the resources 15 and 20 in a month. I believe it will be more popular with users.
Hisense K720U also has its own application market, if you exclude some special games, the total number of applications currently is about 44 models, rich in general, there are no third-party video applications.
It should be noted that Hisense's TV does not recognize the apk file in the U disk, which means that it is impossible to install a third-party APP through a USB flash drive. For the time being, we can only hope that the official launch of more TV applications, or you can only watch the resources of China.
In addition, the management application does not long press the Home button, but instead has an "i" message key on the remote control. With this key, the user uninstalls the application and can also add frequently used applications to the desktop.
Unlike many smart TVs, the Hisense K720U can adjust image and sound parameters directly during playback, and is updated in real time, which makes it easier to get the most satisfying display results.
In the U disk identification, it directly displays the preview of the selected resource on the right side, and gives more detailed information such as video size and time.
On the remote control, there are four colors of red, orange, and blue, which correspond to the four modules of “liveâ€, “videoâ€, “game†and “applicationâ€, and can be switched to the corresponding block at any time. For example, if you are watching a movie and stop playing it for a while, clicking the “video†button on the way will go directly to the movie playback interface.
2, a key collection
In the bottom right corner of any online video, you can see four small horizontal stripes: red, yellow, green and blue. At the same time, there are also four horizontal stripes at the bottom of the remote control. Click the corresponding color to achieve a key collection. Features.
The game also supports the double mode, just download "Hello with remote control" on the line, the right side gives the application download address.
In addition, Hisense TV also supports playing some QQ mobile games, such as Tencent's early days of cool running, TV also supports two QQ and WeChat account login, and the data is exactly the same as the mobile phone. At this point, the connected mobile phone becomes a remote control, and the effect of the large screen is very good. The actual trial found that this method is not suitable for racing games, because it is slightly slower than playing directly on the phone, and it is easy to misunderstand the bad rhythm.
4, TV shopping
TV shopping is still tepid, but the experience of Tmall Box in this area has made us shine. With the popularity of smart TVs and the abundance of TV shopping apps, TV shopping will be a basic function in the future. Hisense has also joined the online shopping function and cooperates with Suning e-commerce to purchase directly. The official said the future will also be on-line TV Taobao applications and Jingdong applications.
5. Interconnection with mobile phones
The APP also supports the transmission of local pictures, music and video to mobile phones. The proper principle is DLNA. There are many video APP support.
However, “Tango†can only send favorite videos and local videos to TVs, but it needs a more powerful “Hisense Sharing 3.0†to push online videos.
This APP also comes from Hisense, not only can push the local audio view, but also integrates the "good-looking" and "live broadcast" functions, because the mobile phone search is more convenient and can become a very powerful TV assistant.
From the above series of experience tests can be seen, Hisense K720U as a curved TV, 65-inch sensory experience is far less than the ordinary flat-screen TV 50-inch comparable, will be placed in the living room will be alive "The sense. 4K resolution with dynamic image quality enhancement processing technology, especially dark field image detail enhancement technology, the display screen color is more delicate.
This TV is also rich in functionality, not only supports live TV picture-in-picture, sound back, but also supports remote control one-touch direct, push the video through the mobile phone APP and other features, which is also not common in many ordinary 4K TV .
System, the card switching speed is fast enough, it is very smooth to use, although some of the interface there are traces of native Android, but does not affect the normal use, but like the screen parameter adjustment is more convenient.
This TV will be launched on the e-commerce platform on May 1. The price has not yet been announced. Generally, the price of a 65-inch curved TV will approach 20,000 yuan. No matter what the final pricing of this TV, it is destined to be a "local tyrant" user. Playthings.
When the whole machine is playing normally, the power consumption is stable at about 230W
The maximum temperature of the fuselage is near the heat dissipation hole, and the maximum temperature does not exceed 34°C (room temperature 20°C).
Recently, Hisense introduced two new series of 4K curved TV XT910 and K720U, of which K720U has 4000R golden curvature, supports dynamic backlight control technology and HIVIEW environment engine, also equipped with the latest VIDAA 3.0 system, also provides "one-touch direct" "Feeding picture-in-picture" "sound back" and other features, we come here to see what this is a television.
Do not ask me the price, because now they have not said!
When the TV was delivered, it was also reinforced with wooden shelves, but it was really hard to go upstairs and was removed directly at the entrance. If a 50-inch TV can be run with a box, the 65-inch can only move forward one step at a time.
Open the box, fill the foam with the top and bottom, squeeze the box full, and put a whole piece of foam on the side of the screen. The protection of the TV is very good.
The bracket is tucked into the bottom and fixed with two screws. Although it looks slender, it is actually very stable. By the way, after installing the base, the weight of the whole machine is a little more than 32Kg.
Hisense K720U is 1.45m long and 0.9m high (including a pedestal). You can get both ends with almost full stretch of your arms. Intuitive comparison, this TV can cover the area of ​​4 40-inch TVs.
Of course, the biggest selling point of this TV is the curved screen, which adopts the 4000R gold curvature of the mainstream of the industry.

Come to a side face, because the four speakers are at the bottom, so they are thicker.
In terms of details, Hisense K720U uses an alloy frame, which looks like a kind of brushed metal, but it is very smooth when touched.
The base is a one-piece design consisting of two different textures of metal, the two feet are very smooth, and the front crossbar is finely matte.
The lower left corner of the TV is the indicator light and remote control code identification. It is necessary to place the remote control within 10cm and long press for 3 seconds to match. In the lower right corner, there is a physical switch button just below the corresponding mark.

The following is the effect under the fluorescent lamp at night. When the ambient light is weakened (compared with daylight), the display effect of the picture is better:
Overall, Hisense K720U's screen saturation is very good, with a color gamut of 140%. This is mainly due to its own "bright color enhancement technology." A separate color matching parametric model can be established for different products and adaptive color Processing, the display of the color will be more delicate.
Hisense K720U is excellent in terms of dark field details. Officially stated that the ULED black field is 20 times darker than the ordinary TV black field, which can better represent the dark field details that ordinary TVs cannot express.
Actually, this is indeed the case. When a picture with a very dark background is displayed, it is almost completely dark, and the subject is “flight†and above the picture.
From the perspective of the screen shot above, the display performance of the Hisense K720U is very good, then the actual real strength of this 4K resolution display, we test it with a few professional test charts:
The first appearance is "4K TV resolution test chart"

Of course, whether or not the system works well depends on whether the overall interaction is smooth, whether the interface is beautiful, and so on. Let's take a look.
The main interface of the Hisense system is divided into two parts, the lower part is the module selection, including video, application and notification; the first part is playing the video just watched, so that occasionally returning to the main interface will not cause "slice" The seamless experience is excellent.
From a performance point of view, the individual modules like "Game Center" and "Application Center" all require a certain start-up time of 1 or 2 seconds when they are turned on. However, if it has been started once, it will be very fast when it is switched again. The official 0.1 seconds of switching is not unreasonable.

After installing the official "Tango" application, when a video is selected on the TV side, the mobile terminal will automatically update the video information, basically achieving zero delay. It also supports collection and sharing, provides support for TV screenshots, and facilitates sharing of high-resolution images.
The APP also supports the transmission of local pictures, music and video to mobile phones. The proper principle is DLNA. There are many video APP support.

6, sound return
Many people have the need to watch TV late at night, but what about television sounds that affect their families' sleep? Hisense has specifically developed a "sound return" function. After it is turned on, the TV will transmit the sound to the mobile phone. After the mobile phone is plugged in, the TV can be used to listen to the TV.
