Foreword

First of all, I would like to thank Zhang Da Ma for casting a wink at me and letting me get a big color TV. This sudden surprise made me a little flattered. Although the Aunt 630 was four years old, I actually had three red tests in this way, but it was a small prize in everyone's eyes. However, due to the personality of Virgo, even the small prizes must be self-explanatory. The greatest effort was made to make the evaluation the best. Therefore, in order to write a good review, I made a lot of efforts. The last three reviews were all recognized by Zhang Aunt as the essence. This has also increased my confidence and I believe that only by paying will have a return, and of course it will also strengthen my mind to take root in Zhang's mother's home.

Speaking of the reason for applying for this cool open U55 TV, it is really because the family just needs it. After all, for so many years, the home has been using the TCL 29-inch Otsuka CRT TV that was purchased for about 01 years. Do not look at this CRT TV is out of date, but then the quality of the TV is really good, so more than 10 years have passed, almost no major problems, to replace the 2nd and 3rd order capacitor. I usually don't watch TV very much at home and I spend time on the Internet. Most of the time, TV is still watching grandmother, mom and dad. I would have thought that this TV was outdated a few years ago and I always wanted to A new, big one at home is now so cheap. Even though it is poor, it is not affordable. My dad used to be used to spending time in the holidays, and she has been persuaded me that this TV can be used again. When it is completely broken, it will be replaced by a new one. This TV is also very competitive and it has been a long time. All of them are good, but there are no signs of bad, so they have been dragged to the present. Just in the test, we can see that this red test product can be applied, so we seriously wrote a large evaluation plan, hoping that they can be in the middle of the subsidy. I did not expect that in the end I was really, and when the TV came home, the mother actually did not believe that this was my prize, and thought that I had cheated her. I just regretted not having bought a new TV for my family earlier because my beloved grandmother could not see this new TV because she left me forever in August of this year and remembered her favorite television programs. It is the local "630 News" and CCTV3 Bi Bi Ye's "Avenue of Stars"...

Okay, thank you very much. Let me hear something nonsense and talk about feelings. You don’t talk about feelings about digital products this year. Of course, if you do not like this, please jump directly to the body of the evaluation. Thank you.

Just a few days ago, I took advantage of the Kindle specials into a copy of "Black and White Memories in Shanghai in the 1980s (Chinese Stories)" http://B00JL5ZJCE?psc=1&ref_=oh_aui_d_detailpage_o07_. This is a story book, although I didn't live in Shanghai. But I have experienced many of the things I talked about, so I've been particularly touched. Of course there is also a record of TV, please allow me to extract one of them:

"Every New Year's Eve passed. The New Year's Eve of the Lunar New Year in 1983 made it hard for me to forget. I opened my Diary of the 1983 Lunar New Year's Eve. "Today, I have a lot of guests in my family. Many relatives from Wuxi Deyi and Zhiming Nephew have come to my house. After dinner, there was a good night at home, and I had eaten more than six o'clock in the morning and I almost finished eating at less than seven o'clock. I sat in front of the TV and waited for the broadcast of the CCTV Spring Festival Gala. More than three weeks ago, the news informed CCTV. The news of the first Spring Festival Gala will be held. The family unanimously decided to purchase a nine-inch black-and-white TV set to enrich the family culture life of the New Year. 'I still remember that the whole family was surrounded by friends and family in front of the TV. Excited and excited, because I lived in the desert of culture for too long, I suddenly encountered a gushing stream of springs, eager to enjoy the refreshing nectar of that refreshing nectar. During this period, Zhu Mingqi's song "Our Life is full of sunshine": "Happiness" The hearts of the flowers are open, the songs of love are floating in the wind, our hearts are flying far away, and the beautiful revolutionary ideals are cherished. Ah, dear people, go hand in hand and work together. Into it! I just sang my mood at that time. At that time, the thrill of having a black-and-white TV was absolutely no less than the feeling of having a BMW and other high-end RVs today, because we experienced nothing for so long. Even when a peasant friend in Chuansha, a suburb of Shanghai, bought a small black-and-white TV set, the unforgettable expression he had displayed (see head shot).

Of course, this is just the memory of the author of this book. I believe that each of us has our own memories of television. Especially after the 70's and 80's, we can say that television is one of our only entertainment methods. Unlike today's 90's and 00's, we can enjoy entertainment. There are too many. The first television of our family was Changhong's 14-inch color TV, which was purchased in the mid-1980s. The key-press FM only had 8 channels. This TV brought me a lot of wonderful memories. The Romance of the Three Kingdoms, the Legend of New White Snake, the Dinosaur Extra-Korean, and all kinds of old Japanese anime...are the eternal memories that this little TV brings to me. Of course, I also use this one. There are a lot of FC games on TV. The most memorable thing is to secretly play Silent Night on the night. After so many years passed, I now rarely watch TV, but I still remember the 14-inch color screen that brings me joyful memories.

Well, it seems that nonsense is indeed enough, let us put away the feeling of nostalgia for the old TV, temporarily put down the so-called feelings, with a more objective view of my hand this cool open U55 55 inch 4K big screen Smart TV brings my real experience to everyone. Due to the recent busy weekend, most of the photos were taken at night. This review was written at night and night. Therefore, there are places where photography is poor or nonsense. Please forgive me.

This is the official introduction page of Cool Open U55. Interested friends can check it out.

I. Installation

In only one day, this 55-inch TV was sent to my house by Shun Fu's courier and sent by my father. The whole body is encrusted with "free and flexible love," and the positive eye-catching logo is printed on Zhang Aunt's brand. Although looking very large, but the weight is actually not heavy, and my mother and the mother, it is easy to carry it back home.

The energy consumption label is three levels, not low, if it is a level, it will be fine.

Carefully opened the box, 55-inch big TV quietly lying there, feeling a little excited. Although it was not packed in wood, foam protection was still in place and the TV was intact.

In addition to the TV body, other accessories include: base × 1, remote control × 1, AV extension cable × 1, quick guide × 1, warranty card × 1, parts box × 1, and a through Hollywood VIP recharge card.

Open the box of parts, which are the plug-in, screws and the like of the TV, as well as the remote control board.

Because the family is currently waiting for the demolition of the old house, so do not toss, do not hit the hole hanging on the wall, directly to find an old coffee table on the line, so only use the installation base. The base design is good, it will not be installed, it will be easy to install, and it will serve as a dual purpose tool. The base is also a bracket that hangs on the wall.

But there is actually a screw inside it! And there is no spare screw! Is not my RP too good?

Fortunately, the size of the screw is relatively common, just looking for a broken screw to install it, but this little bit of control I can not help but pinch the sweat.

There is also a digression, the bonus Hollywood VIP recharge card actually expires on December 31, 2013! In other words, this bonus card simply can not be used!

The final installation is like this, the home is more messy, please give the official to forgive me. The 55-inch is really big enough. Compare it with the original TCL 29-inch CRT.

This part of the summary: Installation does not take much effort.

————————————————————————————————————

Second, the appearance of articles

On the whole, the cool-on design is still very design sense, and it is said that it was carefully crafted by the IF & Red Dot award-winning design team. Although it does not reach the declared "artwork" quality, the use of ultra-narrow borders adds. The classic silver-black and curved base looks simple. In terms of appearance, I am still very satisfied.

The front of the TV does not have too much decoration, there is a cool open LOGO in the lower right corner.

U55 is very thin and light, mentioned before, I easily carried it to the home with the mother, read the instructions its weight in 20KG, which may be lighter than the original 29-inch CRT may be due to the use of environmentally friendly plastic shell , but also because of the addition of this plastic also makes it look a little cheap. The thickness of the whole machine is only 17mm, which is regarded as ultra-thin, and it can be easily put on the wall. Since it is an old house, it will not be tossed. It is safe to find a small table.

U55 ultra-narrow frame design, 5.9mm frame, it seems that not only mobile phones, tablet play ultra-narrow frame, smart TV is not far behind.

I think the backboard design is the characteristic of cool open, U55 uses the transparent core board design, the internal wiring, components are clear, can carefully see the composition of components. After all, I’m still a major in electronics and I’ve been playing with TV for a few days at Changhong. However, because I’ve not worked in this professional field, I’ve already forgotten the teacher’s knowledge, but I still feel that this TV is The layout of the circuit and the layout of the structure are reasonable, and the welder is justified. Dare to expose their circuit design to the outside, also fully demonstrates the cool open confidence. And personally feel that the design of this transparent backsheet is very full! It seems to remind people of something...

That's right, this is the real bitterness!

Four loudspeakers are directly above the transparent backplane.

The interfaces are satisfactory. The list is as follows: 3 HDMI interfaces, 3 USB 2.0 interfaces, 1 LAN network interface, 1 YUV port, 2 AV-in ports, 1 AV-out port, and 1 SD card interface. In other words, all of them have. USB port is more intimate with a dust plug, this detail is good.

This TV is equipped with an SD card slot. In addition to downloading the APP and storing local video movies, there is an important function for me to view the photos taken by the camera. This 55-inch high-definition screen looks really good, and the screen quality is good, you can see many of the details usually not seen with a small display. Let me test the compatibility of SD card with this bayonet. Then find out the SD card on the hands of the cabinet, from the Kingston 1G card for ten years, to the Lexar 200X 32G card, can quickly read out, compatibility should be no problem.

This part of the summary: beautiful appearance, ultra-narrow frame, ultra-thin body, transparent back are eye-catching.

Third, the quality of articles

Quality is now a sensitive topic on television. Before I say quality, I must first express my immature attitude, or superficial views, so as not to cause unnecessary disputes.

Now the mainstream of television seems to be smart TVs, and more and more people think that this is the future trend. However, image quality is the core function of television, and it is the most basic function. It is the key to determining the cost of television. People buy a TV just to enjoy the visual effects it brings, so in this regard, image quality should be considered as the core parameters of television. Yes, but not necessarily. The quality of television is important and not so important. Why do you say that?

Take an example of my own experience. I have more hobbies. Many years ago, I had always pursued the goal of pursuing the best results in my own area of ​​competence. For example, I had a fever with music. I used to wrap my party with me. I was always on the IMOD + amp + impedance line. The combination of ER4P; for example, photography, liked good quality before, so experienced equipment upgrades again and again, and finally the D800 and a few shots. And now, when I listen to songs, I like to use the innovative IE3 to listen to the mobile phone. The camera also prefers to use the Nokia 1020 to take a shot. Even when I work, I think the previous D300S+17-55 has been I was satisfied. Now the D800's photo is too large. It quickly filled the hard drive, and it was too bulky. It would take a long time to get tired. The sound quality of the IE3+ mobile phone is definitely not as good as the binding, and the 1020 is the fighter in the mobile phone that can't be compared with the SLR ratio. Why do you become like this? Still, because of his own ideas and changes in the surrounding environment, he no longer pursues the best within his own ability, because as a fancier is very tired, but also requires a solid economic foundation, and now the pace of life is getting faster and faster. What's the matter? As a mobile device terminal, a mobile phone carries more than just a phone call. I can complete the functions of listening to music, taking pictures, and talking on a mobile phone, although it is not the best in terms of single function. So, I think TV is also the same. Nowadays, TV is not just used to watch TV, but as a home entertainment terminal. It also carries more tasks than just watching television, due to the diversity of entertainment. As a result, the family's demand for the picture quality of TV is slowly declining. Of course, whether mobile phones or televisions, mobile devices or home entertainment devices, they rely mainly on the Internet. The development of the network brings more possibilities for their development. Therefore, I liked the Cool Open slogan "For the home Internet!" It can be said that from this point, Cool Open grasped the needs of the times. Do not you ever see the high-rich handsome plasma has been brandished from the palace, since the end of the rivers and lakes, the cost does not fall down after all, can not go into the homes of ordinary people, fans are after all a minority of the few, how to survive in the fierce market competition is the most important issue. So I think the future of television must belong to cheaper, smarter, more functional TVs.

Let me talk about 4K. I think 4k TV has little or no significance for ordinary consumers. First of all, in the home environment, the definition of 4K is affected by too many factors, such as the screen size, viewing distance, and 4K source, which cannot be satisfied without demonstrating the advantages of 4K resolution. Secondly, to buy 4K TV is to watch high-definition video, this is a double audio-visual enjoyment, not only have to look, have to listen, but the current solution, only rely on the TV's audio decoding capabilities, there are many problems in high-definition audio, Many formats do not support this, which requires a separate audio decoder to connect to the speaker, which in turn brings a large expenditure. The last and most critical issue is the problem of 4K sources. Now that the bandwidth of home networks is not enough to support online playback, the occupation of a complete 4K film with hundreds of G of space is not acceptable to ordinary families. So now 4K is more of a symbolic product for the average consumer. Even the mobile phones have entered the 2K era. Are you still shy to tell others that they are not using 4K TV? (laughs)?

U55's picture quality is not good? First go to an official description:

"Cool open U55 has a 55-inch LGD 4K UHD original hard screen, resolution of 3840×2160, with 10bit color enhancement, the third generation of six basic colors, scene screen change and other advanced features, with 4K graphics engine PRO, you can use the chip Adaptive video coding algorithm to realize point-to-point restoration of 4K images, reconstructing image details and precise image processing through MRT image micro-reorganization technology, performing intra-field interpolation frames through motion estimation and motion compensation, raising the refresh frequency, and effectively solving the traditional 4K The problem of jitter and smearing in TV sports."

Looks like it is very powerful, in the end is it good or not? Part of the picture quality because there is no professional instrument for testing, so I used the most primitive screen shot method, respectively, shooting static images and dynamic video. Shooting equipment D800+24-70, tripod and shutter release, the picture is all original JPG, no post-processing. The static pictures displayed are 4K and 8K pictures downloaded from the Internet, as well as photos taken in their own SLR. The source of the dynamic video is a 4K video downloaded from the Internet. As for the effect, please judge by yourself.

The first thing to note is that there are two ways to open a still picture, 1 is to open it in the main menu "My" with media playback, and 2 is to open with a 4K picture player. I feel that with the 4K picture player open, the contrast and saturation of the picture have been greatly enhanced, and the media player was originally used to open the video, and after the picture is opened, the “Loading” prompt will be displayed for some unknown reason. However, the performance is closer to the original figure. These are my SLR jpg artwork, media player open, 4K image player open, 100% screenshot of the original image focus, you can see the obvious difference. The following display pictures are opened with 4K picture player.

8K picture downloaded online, amazing quality

Followed by the online download of 4K wallpaper, the display is also very good

These are photos of themselves with D300S and D800, thanks to high pixels, especially the D800 full output 7360 × 4912 resolution, the display effect on the TV is very good, not worse than the downloaded 4K wallpaper.

Followed by the online download of 4K video test. Only three videos were downloaded. The beautiful women took the roast duck and ducks to take off and the famous Viennese scenery film called 4K was shot. The little three videos, the length of a few minutes, was close to the size of a G. It can be imagined. A complete movie is not yet 100 G. It will take time for 4K to go in search of people's homes.

Looking at the whole, it feels like the beauty of the beautiful ducks is the best, and the scenery in Vienna is a bit worse.

Then on the last two online watching super-clear video handheld screen shot.

The last is the actual effect of watching television programs. It feels okay. Saying that the recent "Red Sorghum" really is not a fire, ah, Mom and Dad are chasing every night.

The overall picture quality of the TV feels good, but there is a big problem, that is, the screen is very light leakage. This is the screen shot when I use the whole black background (solid background in the drawing) when the home lighting is all black, and you can see the backlight distribution. Very uneven.

Let's look at the viewing angle again, and we're still quite satisfied.

There are also official claims that the U55 has passed the DTS 2.0 certification and Dolby surround sound, using four speakers, but in actual use, it still feels boring sound, lack of three-dimensional effect, you can watch TV programs, but enjoy high-definition The video seems powerless. To enjoy the shock of high-definition audio, still have a separate audio decoder and speakers.

This part of the summary: TV picture quality is good, but the screen is serious light leakage, speakers are unsatisfactory.

————————————————————————————————————

Fourth, the system


Turn on the TV and you can see the cool advertising language. Since the slogan is "born for the home Internet," of course, you must first access the Internet. After booting, there is a setup guide screen to set up step by step. However, I encountered a little trouble on the wireless network connection.

Because my wireless network password is ASIC II 64-bit encoding, only use the input 5 bit on the line, the results when connected to the TV life and death to me that the password length is less than 8 bits, and mobile phones, tablets are all connected when there is no problem ah . Had to enter the router to change the password.

Then you can sign up for a cool open account, you can recharge online HD movies, forehead, this...

Now that we talk about the UI design of the Android system, we must talk about flattened, rounded matrix and the like. Cool open U55's UI is similar to the WP-based suspension magnet design, it is relatively simple and refreshing, will not make people feel that there is a conventional Android kind of dense phobia impression, the operation is also relatively fast. As for Android's set of hardware parameters, what 10cores, 2G memory, I'm not very concerned about the interface operation is very smooth, that is, after 2 or 3 years will not be Caton.

Press the menu button to enter the interface, the home page is divided into recommendations, video, applications, mine, set five categories. When you first got your hands, there were only four menus and there was no "recommendation." Later, there was no upgrade to the system. The versions before and after the system were all the same. Before and after the comparison, only the 4K technology changed, and I didn't understand what was going on.

In fact, smart TV, everyone will have to look at film and television, installed applications and the like. "Recommendation" is of course the real-time update of the latest and most popular video resources, you can also view the video watched in the past week.

The following enters the film and television menu, this piece of linked gifted friends and Pule, in fact, needless to say we all know that, due to the limitations of light, available resources, cough and cough ... but the mountain people have their own coup, cool open very cleverly bypassed this The Maginot Line, mentioned later.

Fees, or fees, may the ordinary family are reluctant to spend this money? However, there are still some free resources.

Followed by the application. Download applications need to be plugged in with an SD card or a USB flash drive. There are not many apps available for download in the store. TV applications are still different from mobile apps. As for what applications are installed, there is not much to say, or else it becomes an APP recommendation. What kind of people do you have in mind? What HDP Live, TV Cats, All-aggregate, Tatevision Video, Grape Game Room and the like.

As for the game, other Android games have no interest, they are still considered to be a hardcore player. I'll try the next simulator. The support for the handle is very good. I would like to pull out the Beitong that has been eating for a long time. The familiar BGM suddenly burst into tears. By the way, the phone can also be used as a handle, oh, sweep the QR code, but it feels ...

Try WPS again, open the document very smooth.

The last is setting, vulgar use running score to run a point, what is this level? It seems to be less important.

This part of the summary: UI design is relatively simple, as for resources, or get on a box, TV comes with resources can not fight!

————————————————————————————————————

Fifth, remote control articles

The reason why the remote controller is taken out alone is because many of the remote controllers of the box have a bad touch. U55's remote control is relatively light and thin, the surface with a black matte treatment, the overall feeling is cheaper, but better than some of the box's remote control, such as Lynx box the same remote control. Actual operation, the key touch is poor, there is no obvious key feedback, the operation is not very accurate, often missed, missed phenomenon.

The button design is relatively simple and has a diamond layout, retaining only its basic functions and simplifying many unnecessary buttons. The key layout is different from the conventional TV remote control.

The button battery used in the remote control is buckled from the bottom and it is more convenient to change the battery.

This part of the summary: remote control feel really bad, lowering the overall quality of the TV, hope to improve.

——————————————————————————————————

Sixth, APP and function extension articles

Cool TV can use the store to search and scan the QR code to install an app called "TV pie" or pay attention to the official WeChat subscription number. It can be used as a remote control, and can also be used to push videos to TVs. Resources are resources on the television side. This bypasses the limitation of light and solves the problem of insufficient television resources. This app has a IOS version and an Android version. Of course, ignoring the WP user, I wanted to compare the differences of the next few versions, but it seems that there is no different place, so I gave up.

This is the main interface of the IOS version.

This is the Android version of the main interface, the following screenshots are using Android-side APP.

When you open the APP, the U55 is automatically connected. It can be seen that the site includes some major network sites, so the resources are not a problem, and basically the common video resources can be found. The feeling I used to push Xin Fan’s animation is very good. Because the instructions sent by Zhang Aunt clearly stated that the evaluation content does not involve the XX site, so there is no need to say more, we all know how to use. Choose a good video, directly at the top of the push on the line, other settings and look like a cool video, you can choose the film source, like me with a small water network, tearfully choose standard definition ah, Chaoqing completely unable to move . With this app as a supplement, the resources really have everything. Personally I think the boxes can be used.

Of course, it can also browse the local videos, pictures and music on the mobile terminal. The function is very practical.

This is used as a remote control. The effect of the up and down, left and right strokes is equivalent to the arrow keys on the remote control. Most of the functions on the remote control have been made. To a certain extent, they make up for the shortcomings of poor remote control.

Of course, various settings of the TV can also be adjusted.

Let's take a look at the official WeChat situation.

The function of the WeChat public number is almost exactly the same as that of the TV school app. It doesn't seem to say anything. However, WeChat has a very niche function, that is, after the device is bound, it can remotely push TV resources, as long as the TV is turned on and is in a networked state. After living separated from her parents, can the video that they are interested in be pushed in time? However, I haven’t tried this feature yet. Imagine that it looks good.

Speaking off topic, we paid attention to the official WeChat, that is, the WP system can also implement the push function, and made up for the lack of TV school APP regrets. Poor WP ah...

This part of the summary: With the TV school and the official WeChat, video resources is not a problem, looks like a box is not needed!

——————————————————————————————————

Seventh, summary

Well, the experience is here. Overall feeling, all aspects are relatively balanced, with the official price of 4999, higher cost performance, fully meet the daily needs of the family, is a good home entertainment terminal equipment, two elderly people are also very happy to use, although at the beginning they are not very used I feel that the TV is a bit big, and I gradually get used to it after watching it for a week. It's still the old saying "I can't go back with a high-definition screen," but they still only watch TV programs, not movies and videos, so this Most of the features of TV are not used by them, but this TV is still a good choice for family value. This time, I finally changed my TV for the family. They don't say that I was spending money. I'm really resourceful. But in the end, I can't write it. So I sum it up again:

Advantages: 1, beautiful appearance, ultra-narrow frame, ultra-thin body, transparent back are bright spots.

2. The system UI is simple and easy to use. The TV mobile phone terminal is very rich in resources and has good expansion performance.

3, good quality, cost-effective.

Disadvantages: 1, work needs to be further strengthened, especially in the details.

2, poor sound effects.

3, the remote feel very bad, I feel very cheap.

4, the screen leaked serious.

Finally, thank you all for watching. Thank you once again for the opportunity of this evaluation given by Aunt Zhang. Will there be evaluation opportunities later? !
