First of all, international conventions, thanks to Zhang Aunt and the manufacturers, thank Xiaobian, let me once again after a year.
Since it is evaluation, nonsense will not say more, get on the train! set off! Welfare appears at random, my wife does not mind showing up, but also ask everyone to tap

I. Product introduction
Cool open, the domestic branded television company Skyworth's sub-brand, is currently operating independently. Its television products are mainly divided into 4 series: T series, A series, U series, K series
The four series are positioned as follows:
T Series : flagship series, take the art route, the top industrial design and high configuration
A series : The second flagship series, featuring the latest technology, reflecting the R&D capabilities of Kukai
U series : 4K TV, cost-effective, but higher than the K series
K Series : Mainly cost-effective, most of the series of products for the 1080P full HD screen, the new models have recently joined the 4K screen
This time the test product is the flagship A series, the latest 50-inch cool open 50A2 HiFi big content TV , the main selling points are as follows:
1. HiFi : The top TV speakers designed by Cooper and JBL
2. Big Content : Two years of love for the iQiyi TV version, worth a total of 598 yuan. In addition to music, education, travel, shopping, games, etc.
3, support 4K HDR video : HDR high dynamic range image, is a new concept of manufacturers in recent years, can allow the picture to show more details
This review will set aside the book data and focus on the above aspects from the perspective of daily use experience.

Second, out of the box
Here to add, there are only 2 rack screw holes behind Coocaa 50A2. If you want to hang a wall, most 4-hole racks will not be able to use them. You must use a 2-hole rack. 2 hole racks are not adjustable angle, we must pay attention to when buying!
Once the landlord was also a non-Dafa and Matsushita plasma not to buy people, but unfortunately they usually watch TV less, family members are accustomed to the millet box, so last year when the decoration began with a 55-inch millet TV 2, although overall it is good, but the appearance details In particular, the processing of joints is still not completely satisfactory. And this time the Cool Open 50A2 is indeed more in place.
The following is a comparison of Cool Open 50A2 (hereinafter referred to as Cool Open) and Millet TV 2 55 inch (hereinafter referred to as Xiaomi).
The thinnest 50A2 is actually measured at the thinnest point and is 1.07 mm thicker than the official one. However, this is already very thin. The advantage of the thin body is that the wall will cling to the wall and the visual effect is very good.

Conclusion: The design and process of Coocaa 50A2 gave me a big surprise. From the exterior design to the manufacturing process, they all reached a very high standard. Family members also liked it very much.
Here is the welfare time
========== I am split line ==========
Third, performance and operational fluency
As a new product, Coocaa 50A2 has a fairly high configuration
High configuration can be said to lay a hardware foundation for a good user experience. But good hardware also needs an excellent system to support the following test for the user experience
3.1, boot speed test
As a TV with its own intelligent system, the biggest difference from the traditional TV may be the boot time. Although the traditional TV-connected TV boxes still cannot solve this problem, the problem of the length of boot time will be amplified when accessing radio and television signals, affecting the user experience.
3.1.1, start the power off
Measured the cool open 50A2 boot with 17 seconds, millet TV 2 boot with 28 seconds. Taking into account that the Android system will be stuck for a long time, cool open time is still acceptable, and millet boot time longer.
3.2.2, start up in standby mode
Measured millet TV from the standby mode is basically seconds to open, and cool open 50A2 each boot takes 17 seconds, this is even better on the millet TV.
3.3, system fluency
When testing the fluency of the system, the landlord took a video, but the video did not reflect the problem, so the landlord dictated. The actual operation process, from the point of view of the movement of the cursor and the start of the application, the system of Coolopen and Xiaomi is basically the same, and the operation is very smooth.
For the TV remote control, the version I currently get is not very easy to use. It is said that the manufacturers are more sincere in the future to replace the Bluetooth remote control, thereby enhancing the user experience.
Conclusion: Cool Start 50A2 is faster at first boot, but lacks the function of seconds after standby. The operating system is smooth and doesn't get stuck, but the remote control doesn't work well and it's easy to lose the signal. System optimization and improvement are large.
Welfare can not be less

Fourth, quality comparison
Coolo 50A2 is a TV supporting 4K HDR. HDR TV is the concept of hot speculation in the past two years. The landlord did not understand it before. This time, he specifically made up for it. He felt that it was necessary to chat with everyone about this topic. There was something wrong to welcome everyone.
First of all, let's first understand what are the characteristics of HDR video? The following content is taken from Du Mother:
Compared to ordinary images, HDR (high dynamic range image) can provide more dynamic range and image details. According to LDR (Low-Dynamic Range) images with different exposure times, each exposure time corresponds to the best detail The LDR image is used to compose the final HDR image, which can better reflect the visual effect in the real environment. Under the influence of HDR, the colors presented by the TV are more vivid, the black is deeper, and the objects on the screen are clearer. At the same time, the hue of the picture is also enlarged, alternating between cool and warm colors. 4K HDR is a more advanced image processing technology than 4K. Under the HDR video and TV combination, the color presented by the TV is more vivid, the contrast between the brightest and darkest picture is more distinct, and the objects in the picture are more realistic. As a result, the gamut of the picture has also been expanded.
The landlord summarizes according to his own understanding: HDR video can show more details in the light and dark areas of the screen, and can make the colors of the screen more realistic.
for example:
We usually see the film, is not often encountered similar to the situation shown in the above figure? Looked particularly tired? Is the effect of HDR TV very impressive?
but. . . After all, this is an ideal result. The full HDR is a set of specifications from shooting to storage to decoding and playing.
The landlord made a simple schematic
In other words, many details are not retained when the ordinary film source is shot, so HDR TV can not restore these details.
So, support HDR, and the manufacturers did not mention the panel's cool open 50A2 picture quality in the end how?
4.1. Test using 4K TV special test chart
4.2 Play 4K HDR video
Here the landlord must spit first, 4K HDR video is really hard to find! ! Too hard to find! ! Too hard to find! ! Landlord found a long time to find a more standard video, the parameters are as follows
Resolution: 3840x2160
Size: 912 Mo
Length : 02min 50sec
Package: MP4
Coding: HEVC
Rate: 45 Mb/s
Color depth: 10 bits
Color Space: BT.2020
Sampling: 4:2:0
Number of frames: 59.940 fps
Others: HDR
4.3, playing ordinary 4K video
The first game of this European Cup, France's 4K video to Romania. Shooting is done during playback, so many screens are blurred and the actual viewing effect is clear
For ordinary 4K video, 50A2 has the same HDR bonus, better display
4.4 Play Blu-ray 1080P video
Cool open 50A2 HDR bonus effect for ordinary 4K video, so the landlord is looking forward to using her to play 1080P video, after all, now and for a long time to come, 1080P video is still the mainstream.
Cool open 50A2 also has bonus for 1080P video, really a big surprise! The same scene of the millet TV has been black can not see! The landlord strongly recommends that valued friends who have recently purchased the plan to consider HDR TV!
4.3, screen dynamics
The screen dynamics cannot be expressed in photo videos. The landlord continues to dictate.
Cool open 50A2 is equipped with MEMC motion compensation algorithm, the effect is very obvious. Take the headline of the great American drama “The Game of Powerâ€, there are a lot of fast-moving shots of the screen. Playing on the Coocaa 50A2 can be said to be silky and smooth, and no streaking is no frustration. When playing with the millet TV 2, the smear is not obvious, but the frustration is stronger.
Conclusion: As a new generation of products that support HDR, Coocaa TV 2 has won the 50A2's previous generation of video games with the same quality and dynamic performance.
Continued welfare

V. Operating System and Content
As a smart TV, the operating system and content are very important. Then the landlord analyzed the advantages and disadvantages of the system according to his own habits, not necessarily for everyone, only as a reference for everyone to buy.
5.1 Operating System
The layout of the entire system interface is horizontally tiled, the content on the front page highlights the content, and the UI design also meets the characteristics of “big content†TV. The “...†button on the left side of the screen means that pressing the left arrow key on the remote control will bring up the menu. The downloaded third-party applications will receive "My Applications" at the red circle.
The landlord felt that there was some lack of "my application" design. Although Coolcom provides a lot of content, users generally have several commonly used applications, such as live TV, system cleanup, and so on. Every time you want to enter from here, finding an application and running it can be cumbersome. It is advisable to leave an area on the homepage so that users can add frequently used applications to the homepage, which will be much easier to use.
The "..." button on the left side folds the common menu of smart TV, as shown below
5.2, content and update speed
Cool open 50A2 application center provides hundreds of applications and game downloads, as the system's own application center, this number is regarded as more
More than 600 games and software have been added together. This does not include the use of video and audio tools.
The purchase of the iQiyi member for 2 years and the amount of content that can be watched is guaranteed
The movie is relatively new, it was a film released some time ago
There are also many popular TV dramas, mainly domestic dramas.
5.3. Children's mode
The children's model is also one of the unique features of this cool new product. Child mode can be seen as a simplified version of the entire system. In addition to the official content provided is for children, applications downloaded by the user in the normal mode can be authorized for use in the child mode.
The content is specifically for children
↑ parents can authorize the application and set the viewing time, but the prerequisite is to do an arithmetic problem, exit the children's model also need to do math problems to prevent children from seeing what should not be seen, we all know
↑ Set up time and authorization applications
5.4, ​​read NAS, mobile hard disk playback test
The landlord copied all the previous test videos from the NAS to the mobile hard disk, and played them through the mobile hard disk. But also encountered a problem, subtitles and images are not synchronized, and the gap is getting bigger, more than 40 minutes of video, to the end of the subtitles have been slow for more than 2 minutes. The same subtitles and videos can be used normally on computers, mobile phones, and millet TVs. This issue should be optimized and resolved in future firmware versions.
Conclusion: After cooperating with iQIYI, Kukai has ensured rich content and resources are relatively new, and can be freely watched during the two-year membership period. Children's models are well-received. After setting the viewing time and permission, you can rest assured that your child can choose what he likes to watch. In contrast, there are still some problems in system design and compatibility. This should be the reason why traditional hardware manufacturers have accumulated less software.

Six, sound effects
As the saying goes, the sound quality is good or bad, mainly depends on writing. Although the landlord's writing style is very bad, but still want to express it, the cool sound of the 50A2 is beyond my expectations.
The landlord originally bought a millet TV 2 with a sound bar and a subwoofer suit. Before the test, for the sound quality, the landlord was biased toward the millet TV. However, the test results are exactly the opposite. The only advantage of the millet TV 2 package version is that the volume is lower and louder, but it can be said to be a complete defeat in the quality of midrange, treble, resolution, and bass.
When watching movies, the landlord will turn off the "Dolby Sound" option in the setting of the millet TV. The reason is that the resolution is too bad. The vocals and the background sound are mixed together. It is difficult to hear what the characters are saying without watching the subtitles. , and cool open does not have this problem completely.
In terms of bass, the cool low volume is not as good as Xiaomi TV, but it is very powerful. Millet's bass is relatively loose, cool open bass is more compact.
6.1, play music
6.2.1, playing online music in the system
Cool open itself does not provide music resources, but provides a variety of TV version of the music application download. The landlord usually uses NetEase cloud music on the mobile phone, but he doesn't provide it, so he chose QQ music to test it.
QQ Music provides a wealth of songs and MV resources, a variety of classification, ranking, playback is good, but can not adjust the sound is very regrettable. QQ Music does not provide sound adjustment options, and the sound settings in the Cool On system cannot be tuned out.
6.2.2, playing local music
The landlord used to collect some flac music for a while, saved it in foobar2000 to WAV format, and later abandoned it after using online music software. This time the evaluation was working.
The voice of my brother is well restored
There are 4 preset options in the sound mode. The "standard" model is relatively balanced, the "music" mode has a slightly more prominent vocal tone, the "news" mode has a more prominent vocalization, and the "4K" sound effects simulate a number of echo effects, somewhat akin to listening to live concerts.
Listen alone mode is to turn off the screen, you can save electricity
6.2.3, wireless connection mobile phone to play music
Turn on the audio mode, you can use Bluetooth to connect the phone and turn it into a Bluetooth wireless speaker. Turning on the audio mode later will automatically connect the paired phone.
After the connection is successful, you can use the music app on your phone to play it. There is no functional difference from the normal Bluetooth speaker.
However, there is one thing that must be given up. When the TV is turned off, the speakers are also turned off. Each time you use it, you must go through the process of “power on—turn on the audio mode—connect the phone—turn off the screenâ€, which is very tedious. The remote control signal problem mentioned above caused the landlord to dip in bed and listen to music for a long time.
In contrast, the external speakers of the millet TV 2 are more humane. After the TV is turned off, the bluetooth signal of the speaker can be directly searched. After connecting, the music can be played directly, and the user experience is better.
Conclusion: For the TV speakers, the cool open 50A2 speakers perform very well when playing music. Maybe it can't reach the 3,000 yuan sound effect mentioned in the publicity, but it must be above the thousand yuan level. The supporting software features are lacking, the operation flow is slightly complicated, and the experience is not as similar to competing products.

Seven, summary
The landlord first gave each indicator a point from his own point of view. The perfect score was 5 ☆ (using the same product as the criterion).
Performance: ☆☆☆☆
Quality:☆☆☆☆☆
System:☆☆
Content: ☆☆☆☆☆
Sound quality: ☆☆☆☆☆
Summary: As a new product introduced by the traditional hardware manufacturers, the hardware of Coocaa 50A2 has performed well. After cooperating with iQIYI, the content is rich, and the software is still a short board. (I don't know if I'll be chased honestly)
Purchase suggestion:
1, as a 50-inch TV, the official original price of 3499 looks higher than the price of competing products 2999. However, support for HDR, Bluetooth Speakers of more than a thousand dollars, motion compensation, and two years of iQIYI members are all extra points. If there are more concessions, you can pick them up.
2,50 inch personal feel too small
3, motion compensation is very necessary, look not so tired for a long time
4. HDR also has an increase for normal video. It is recommended to give priority to TVs supporting HDR within the budget.
5, 4K or 1080P individuals do not feel entangled. 1080P has been introduced for more than 10 years, and it is not yet fully popular. 4K is far away from the future and it is difficult to see the difference when you watch it from afar.
6, smart or non-smart TV to see personal preferences. Smart TVs are convenient and only need one remote control to handle it. The disadvantage is that the system will get more and more cards in the future. Fortunately, other TV boxes can be connected externally. Non-smart TVs boot fast, but it is inconvenient to hold two remote controls. The panel technology is updated quickly, and it is also facing the problem of elimination.
Finally, suggestions for choosing a TV (personal opinion): Budget> Size> Motion Compensation> HDR> Resolution> Smart
========== Complete Article End ==========
Really gone
What?
The 8-inch tablet will have a big impact on the 7-inch and 10-inch tablet market. Because the portability of an 8-inch tablet is stronger than that of a 10-inch tablet, and the usable area is larger than that of a 7-inch tablet. The most important thing is that the price is more moderate, which is much cheaper than a 10-inch tablet. It can be said that the 8-inch tablet computer has a good balance between portability and screen display area, and is more likely to be favored by the majority of users.
