Ecology is the word most mentioned by Internet TV brands in recent years. However, not all Internet TVs are playing ecology. Cool open is a typical example. On May 24, at the strategic launch conference of the “New Big Non-Ecological Content†Big Value Platform, Cool Open officially announced a smart TV that features HIFI and “big content†- Coolo 50A2. Next, we will unveil the mystery of this TV and see how it counters the "eco-pattern."
We are fortunate to be able to get cool new TV prototypes in advance, and we can't wait to see what this HIFI content TV is. This time we got the cool open 50A2 with a screen size of 50 baht.
As a TV editor, one of the benefits is that, as a porter, the 50-inch TV can now be handled by one person, from unpacking to lifting the TV and accessories.
The Coocaa 50A2 TV stand needs to be installed on its own, with screws and tools required for installation. All-metal tripod design is to make the TV more stable and optimal protection, while the bottom of the tripod has a non-slip mat, in a special environment to prevent the sliding of the TV.
Appearance: All-metal temptation
With the continuous advancement of technology, television manufacturers have become more and more skilled in the use of metal materials. At the same time, the metal material has a good performance in terms of visual perception and stability, and it is popular among consumers. This is also applicable to smart phones.
Cool open 50A2 front gives a very simple feeling, the overall relatively tough, atmosphere, the bottom of the TV screen temperature is quite high, the continued heat will make the screen itself metal deformation, using a metal front face perforation is not only conducive to heat but also reinforce the bottom It is not easily deformed, but it also prevents dust from entering and can also block moisture vapors and extend the life of the TV.
As one of the most important characters in the living room, TV has always been one of the most important criteria for consumers to purchase. The metal body and the foot stand only ensure the stability, and the ultra-thin features have become more and more the current design trends in TV appearance. Cool open 50A2 has 9.9mm ultra-thin body, using hot stamping process to make the frame more full of metal texture.
In the frontal details, the most eye-catching of course is the metal grid at the bottom. Not only does it play a decorative role, it is very forcible, and it has a good heat dissipation effect. It also has an effect of prolonging the service life of the TV. The Bluetooth logo on the left has a small indicator that lights up when the Bluetooth device is connected. By the way, Coolo 50A2 supports Bluetooth 4.0. On the bottom right side, there are acoustic logos for Coolo and JBL. As for acoustics, it will be mentioned later.
The back rib design is exactly the same as the ribs on the Samsonite travel case. Under the premise of ensuring the slimness and lightness of the metal back plate, the reinforcing ribs made him extremely strong. The whole piece of metal is easily bent under the protection of a non-reinforced rib, and the rib design combines both design and practicality. The two sounds are very bright, and it is said that the bass radiators of the JBL above a thousand yuan are creatively used on televisions and are jointly designed by Kukai and Harman. The bass effect is enhanced by the air movement, and the four bass radiators enhance the bass in the front and rear.
In terms of interfaces, TV interfaces have become more and more abundant with the increasing range of applications and functions of smart TVs. Cool open 50A2 shows enough sincerity on the interface, HMMI2, 0, USB3.0, network interface, etc. are almost always equipped with the best standards. In addition, in terms of storage expansion, the general SD card has also been replaced with a TF card similar to that of a smartphone, which is convenient for consumers to use. At the same time, rubber dust caps have been added and consideration is very considerate.
In fact, there is not much to say about the remote control, from the previous white style to the current black tone, it has maintained this style. The shape is more rounded, the button layout is more reasonable, and it's very comfortable to hold it in your hand. For television, the niche button battery was no longer used, and it was replaced with a standard two-section 7 battery.
Summary: Cool open 50A2 has demonstrated enough sincerity in terms of price, design, or interface configuration, and it has also achieved enough closeness to the people. Tough metal front face, full metal tripod gives a very solid sense of security. The back reinforced backplane and rich interface configuration let you freely choose the use of multiple TVs. As a Ferrari Queen Audio, JBL has been honored for 70 years worldwide. A2's audio is jointly designed by Coolo and JBL, and even obtained JBL A-level certification, matching 2800 yuan professional audio, providing guarantee for VIP-class audio-visual enjoyment.
Screen: excellent color
The quality of the screen determines the quality of the smart TV to a large extent, Cool open 50A2 is located in a smart TV TV which focuses on HIFI, the screen can not be ignored, the price is only 3499 yuan (two years also added iQiyi members, value 598 yuan), as a rational consumer should understand that the price of 3,000 yuan to buy a screen quality of million yuan TV that is impossible. After our evaluation room test, this screen was comprehensively evaluated. The screen quality was in the upper middle level, and the color was excellent, but it was also slightly insufficient.
The five-dimensional performance chart, based on the evaluation results, makes a comprehensive evaluation of the performance, brightness, contrast, application, and power consumption of the genius, and finally obtains an average score. Cool open 50A2 final score 8.5, in the current television level in the upper and middle.
Color performance test
In the color saturation test, cool open 50A2 TV performance quite satisfactory, careful observation can be found, the test image shows that the edge of the color is not normal, and part of the color is not too natural. However, the final test NTSC color gamut is as high as 79.28%, and the performance is still good.
Compared with the NTSC standard color gamut range, Cool Open 50A2 can reach 79.28% of the color gamut is still a little small accident, as the author said before the 3,000 yuan will inevitably buy less than 10,000 yuan level of cash, but it is enough. In the brightness test, Cool Open 50A2 is very good, all parts can reach higher brightness, and the gap between them is not too large, and the uniformity is good.
The color performance of this picture is more complicated, and it fully tests the color reproduction of the screen and the ability of the color transition. From the point of view of each color yarn ball, cool open 50A2 has a good performance in color reproduction. However, when you look closely, you will find that there are color fusions between the yarns with different colors that are close to each other, and the transition details are general.
Unlike the previous one, on this side view, the Cool Open 50A2 performed well, and both the color reproduction and the detailed performance had a good result. The sheen of the silk thread was vividly presented.
Light control performance test
Before the brightness test, I turned off the TV's screen dynamic adjustment function and adjusted the screen to the maximum brightness. Cool open 50A2 maximum brightness reached 310cd / O, the average brightness reached 266.78cd / O, the results are quite good. It can be seen from the screen that the light and dark details in the picture are clearly displayed.
Grayscale performance, from the screen really making proofs can also be clearly seen between the 0 to 15 steps are clearly distinguished, 16 gray-clear and legible, proved cool open 50A2 in light control performance has a very good performance.
By the time of the proof test, the overall picture in the above picture was dark, Cool Open 50A2 can show the details of the dark part of the picture (tree lines) clearly, but at the edge of the screen, you can see a slight obvious light leakage, but this is also the LCD The common problem of the screen will be a bit more. In the overall dark picture, television will take the initiative to improve the overall brightness of the picture to show more details.
The result of this result is obviously improved. Left and right sides, the restoration of black and white is very good, and there is no obvious light leakage at the edges. People's clothes are also very well separated from the surrounding environment, the beauty of the skin has also been a very good restore, the overall performance is very good.
Dynamic performance test
In view of the fact that more and more people tend to watch live sports broadcasts on large-screen televisions, the dynamic performance requirements of televisions are also increasing.
The picture taken by the fast moving train can clearly see the other side of the eaves through the window of the train, proving that the Cool Open 50A2 performs well in the dynamic performance, and the general situation will not be a case of streaking. This is for watching sports. Live broadcast is crucial.
As for the actual performance, we can look at the following proofs, Kuo Kai 50A2 this screen response time is 9ms, in the daily viewing should not have any effect.
Coocaa 50A2 supports MEMC motion compensation algorithm to watch exciting sports events to eliminate jitter tailing, while reducing children's eyes fatigue, greatly reducing the TV's impact on children's eyes.
Power performance test
The first test is the TV's power consumption performance. By playing different color photos, the power consumption value of the TV is recorded. From the above table, it can be seen that the performance of Coolo 50A2 is still quite good.
Summary: Cool open 50A2 on the screen performance can be said that the advantages and disadvantages are obvious, the disadvantage is that all the LCD TV commonalities - different levels of light leakage, a little performance is in a higher color gamut, good color reproduction and light control performance . At the same time, MEMC motion compensation also provides a reliable guarantee for good dynamic performance.
System UI: smooth and simple, resource-rich, send 2 years love Qiyi members
Intelligent system can be said to be the soul of smart TV, cool open 50A2 uses Cool open 5.0 system, simple UI style, rich audio and video resources, in the Mstar 6A938 flagship TV chip and "2GB +8 GB + 128 G expansion space" powerful configuration escort The fluency is excellent and the experience is excellent. Another point worthy of praise is that the two-year TV version of iQIYI members worth 598 yuan on television purchases can enjoy a large amount of high-definition video resources, free from advertisement troubles.
The card style has become the mainstream style of domestic smart TVs, and it is even more concise. There are several main function modules on the main interface that provide a panoramic view. It is very intuitive and naturally reduces the cost of learning.
Cool open 5.0 has the support of ICNTV, Tencent and iQiyi in terms of resources. Coverage of movies, TV dramas, variety shows, etc. is very comprehensive. The cinema hot films can be watched synchronously on TV. The movie no longer has to worry about no tickets for cinemas. Now. In addition to TV hits on TV channels, Korean TV dramas, American TV dramas, and Hong Kong and Taiwan dramas, TV dramas are a great gospel for otaku men and women.
Given that major video sites are paying more and more attention to the copyright of video resources, most popular resources and ultra-high definition (4K) resources need to be charged or purchased by members to watch, or only for a few minutes. Coocaa 50A2 comes with a TV version of iQiyi for two years. At least you will not need to purchase video members to directly enjoy the massive charging resources in more than two years. There are more than 6,000 movies, 1300 TV dramas, 1,100 variety shows, and 1,700 animations.
As the protagonist of entertainment in the living room, TV manufacturers began to notice the functions of TV game applications. Ultra-high-definition large screen is the best choice for refreshing gaming experience. With smart systems and increasingly powerful hardware support, game applications are also becoming more and more abundant. Although not comparable to XBOX game consoles, it is still a good choice for daily entertainment. Cool open 50A2 supports external game controllers, body grabs and other devices to provide a rich gaming experience.
Also forgotten that after that update, Coolopen 5.0 added smart home modules, centered on smart TVs, and controlled other smart devices in the home, including air conditioners, lights, cameras, and so on. This is in line with the current situation. With the development direction of smart homes nowadays, various control of air conditioners can be performed on TVs, which is very convenient.
In addition to audio and video, games, smart home and other modules, Coolopen 5.0 also contains educational modules, coolstores, and travel and many other application modules. For kids and students of different school years, there are different types of teaching videos. This is better than asking a tutor. More affordable, and combined with video and audio experience can better enhance children's interest in learning. The Cool Open Mall is for housewives and offers a variety of shopping channels to discover real-time information on essential products at home.
Summary: Powerful hardware configuration is the basic guarantee for system fluency, plus optimization after Coolopen 5.0 is continuously updated, whether it is to open applications, load videos, or switch programs is very smooth. Cool open system built-in film, education, shopping malls, games, music, application circle, travel, brand eight sections, covering all aspects of your family life, fully allow you to feel the level of changes in daily life brought by smart TV.
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. click to download
Features introduced: top built-in HIFI audio, HDR optimization, etc.
Perfect sound quality: In addition to the screen requirements, the JBL Ferrari Queen's sound is very important for the best viewing experience. The Coocaa 50A2 uses the acoustics jointly designed by JBL and Coocaa, and has also obtained A-level certification. It is said that there is a strict rating system within the Harman JBL. Level A is the highest level of television audio certification, the ratio does not exceed 1%.
Coocaa 50A2 uses a balanced dual-bass radiator, and a bass radiator that is only available in the JBL thousand or more audio is creatively used on TV. It is jointly designed by Kukai and Harman. The bass effect is enhanced by the air movement, and the four bass radiators enhance the bass in the front and rear.
Nowadays, due to the continuous improvement of the chip, smart TVs directly play various video and audio formats on the TV. There are almost no problems. In order to try out the audio effects of the Cool 50A2, the author plays the FLAC audio directly on the TV. As soon as it came out, it was felt to be attracted, the sound was very clear, and the bass part was very comfortable to listen to. I was not a professional audio editor and did not know how to describe it. Cool open 50A2 uses the latest HIFI amplifier chip TAS5766, pure sound, no noise, while supporting DTS2.0, surround sound effect is a sense of presence.
HDR quality optimization
HDR has become the hottest technical word for the TV industry in 2016 and has gradually become the standard for flagship TV brands. However, due to the hardware cost and the reasons for the scarcity of HDR video resources, Coolopen 50A2 does not support HDR technology in hardware, but in order to provide a better picture perception, we have added a unique HDR quality optimization technology.
Coocaa 50A2 automatically raises the brightness of the bright areas of the screen by means of an algorithm. The dark areas reduce the brightness and the screen is more realistic. Just like iPhones, it's better to open HDR photos. From the above test sample, the overall brightness of the picture has been improved, while the details in the light and dark areas are very detailed.
Child mode
I remember that in the past, Cool TV had several remote controls, including a standard remote control and a child-specific remote control. The purpose was to reduce children’s control of the TV or allow only children to see specific content. This is obviously not a good measure. So now it is a major feature of the system that the new kid mode has been added to cool TV.
In the children mode, the interfaces, icons, and resources all have targeted changes, tending to cartoon styles, and all the resources that are seen in the audio and video resources are animation resources. The educational modes are also teaching videos for children. The entire system is like It is customized for the majority of children, very human. Nowadays, some movies and television dramas may have a negative impact on the growth of children. If there are concerns in this regard, the Cool Kids 50A2 model is the best choice.
Interestingly, in order to prevent children from accidentally exiting the child mode, a question is counted up after the user clicks to exit. It is only interesting that they can only exit the child mode if they answer correctly.
to sum up
Coocaa 50A2 is a smart TV with a main sound effect. It has made a lot of effort on the sound. The actual experience of finding a sound experience is really good, and for an Internet TV with a price of only 3,499 yuan, it also has a very high price/performance ratio. And JBL A-class sound, really very rare. When this TV is purchased, it will also be presented with a two-year TV version of Iqiyi Video. Can freely enjoy the massive HD resources, and there is no advertising troubles. Needless to say, the system configuration, Mstar 6A938 flagship chip, "2GB + 8GB + 128G to expand the space" to ensure adequate use of fluency. The child model can be one of the highlights of the Cool Open system. It is only because the video and audio resources on the Internet are not all positively affecting children's growth, or whether they should be differentiated.
We are fortunate to be able to get cool new TV prototypes in advance, and we can't wait to see what this HIFI content TV is. This time we got the cool open 50A2 with a screen size of 50 baht.
