Cool Sky is an Internet TV brand owned by Skyworth. A strong after-sales service system is by no means comparable to other Internet TV brands. Microwhale TV high-end products are off-line, while the models taking the goods are more concerned about the offline, excellent offline channels. Rich and flexible after-sales service; LeTV and Xiaomi, as the most popular Internet TV brands, are good at using the after-sales service to conduct “word-of-mouth marketing†and there is no problem. 
This is a very important point of the Hengping review, to understand the level of development of Internet TV to the end, for which we gathered four current high-end 55-inch Internet TV to compare, respectively, cool open T55 OLED, micro-whale TV 55-inch Pro (micro Whale WTV55Pro), music as ultra 4 X55 Curved (Engineering Commemorative Edition) and millet TV 3 55 inches, a catch and kill is inevitable.
Four high-end Internet TV brand products
Since we have defined these four brands as "Internet TV brands," the perfect after-sales system is only the foundation, and we must come up with enough convincing products. 55 inches is an interesting size, the traditional brand flagship product will have a 55-inch model, while the Internet TV brand also attaches great importance to 55 inches, so the 55-inch is a size that can show the strength of the major brands, very suitable for comparison . 
Micro whale 55 inches PRO (3999 yuan): 2015 "Double 11" 55-inch TV Tmall sales championship, micro whale relied on outstanding product power to steal the hearts and minds of a large number of users, this 55-inch Pro is the latest upgrade, adding an independent Image processing chip in exchange for "Rui Lide" color engine and "dynamic picture compensation" technology, solid product workmanship, excellent picture quality, easy to use the system to be continued, can be said that equilibrium is the label of the micro whale TV.
LeTV 4 X55 Curved (4999 yuan): The Internet's first 55-inch curved TV, using the latest MStar 6A938 top TV new, cost-effective is very high, music as relatively prominent ecological content, good at integrating resources "heap hardware", the lack of craftsmanship, products The materials used for work are relatively neutral and the EUI system focuses on the content. However, for users who like curved surfaces, the 55-inch surface + 4999 yuan is very attractive.
Millet TV 3 55 inches (3999 yuan): Redefining "new domestic product" is Xiaomi's ambition. TV is one of Xiaomi's three strategic products. Xiaomi TV is still responsible for its products, design, workmanship, and materials. Quality, sound quality, system aspects can leave a deep impression on people. The unique split design also brings new gameplay. Dare to think and dare to do is also an Internet company must have.
The above four 55-inch Internet TV users can refer to the tutorial: Cool open T55 OLED installation method, micro whale 55 inch PRO installation method, music as ultra 4 X55Curved installation method, millet TV 3 installation method Install sofa housekeeper to achieve third-party application extensions. 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. 
Scoring system: in line with the principles of fairness, fairness and reasonableness
The instrument used in this test is the BM-7A luminance colorimeter produced by Topcon to measure the chromaticity coordinates of the Super 4 X55 Curved TV in different colors, and calculate the contrast, color gamut, color temperature and color saturation according to the corresponding values. Draw the corresponding color profile and so on. Before carrying out this test, we first let the machine work normally for one hour and restore it to the factory mode. The entire test environment is performed in the darkroom. 
Hardware Comparison: LeTV 4 X55 Curved First Game
After detailed description of the horizontal comparison evaluation, first of all from the hardware appearance, put four products together, the design of each 55-inch TV product, work materials, interface layout and some human design gap is indeed At a glance, the results of many colleagues who helped raise the television are almost the same. 
Micro-whale TV 55-inch Pro uses a very narrow frame with a 15.2mm body thickness of the "visual contrast design", this design is actually very risky, but fortunately the overall work of the material used more carefully, the base bracket posture is relatively low, bracket Watching it as music is not as crisp as it is, and it is not as small as millet. The overall look is more honest, giving people a feeling of durability and trustworthiness.
As one of the official "Kinda" three core product lines, Xiaomi TV also carries Xiaomi's dream of redefining the "new domestic product". Xiaomi TV 55-inch is designed with a 9.9mm ultra-thin body and slim base. To be solid, the whole is very refreshing. It's not natural, but it's all in one go. In addition, Xiaomi's unique split design and independent speaker design have successfully created a sense of high-end television. 
Color Gamut + Contrast: The backlight system is extremely critical Instrumental analysis: Popularity of Internet TV Wide color gamut technology
Instrumental analysis is an objective test category, but the same product in the same test scenario, the results will be slightly biased, after repeated tests, take the most balanced test results. Of course, there is still an objective test behind it. The evaluation of the specific core quality part will be combined with the objective test and subjective test. 
Wide color gamut technology (millet TV 3 55 inch actually supports HDR technology)
Millet TV 3S 55-inch launched high-end TV in 2015 and was given wide color gamut technology early, which also extended the market life of this product. It is worth mentioning that this product also supports HDR technology, Xiaomi thinks that at this stage There is no special emphasis on HDR technology. The color experience brought by the cool T55 OLED display technology is still quite good. Users with a budget of 10,000 yuan can focus on this. The micro whale adopts the LG Display original panel, and LeTV uses original Samsung panels. The color gamut coverage is similar to millet.
About Contrast (Backlight system is the conscience of LCD products)
Cool open T55 OLED has infinite contrast without backlight. For LCD products, the backlight system has an absolute effect on image quality. Contrast data analyzed from the instrument can be seen that millet has the highest contrast, not because its brightness is higher than its rival (measured brightness millet 342 nits, micro Whale 354 nits, music as 367 nits), but because millet has the most conscientious backlight system, light guide plate laser technology is a very good control of the performance of the black field, light leakage is the best of the three LCD products, previously millet TV 3S 65 inches We were deeply shocked by the first change in the surface.
The small whale 55-inch TV Pro is more ideal for light leakage control because of its independent image processing chip. Although it is not as good as the TV 55-inch of the Xiaomi TV, it has obvious advantages compared to the traditional TV brand of the same price. Conscience products. LeTV 4 X55 Curved brightness best performance, but the cost is a serious light leakage performance, assuming that, if you intend to use TV to play PS4 game console, then I do not recommend that you buy this product (the screen during the game Loading light leakage) .
Real shot contrast: OLED to a real enemy of the three LCD camp contrast: OLED needs to be brighter, LCD needs to be darker
In order to visualize the differences in the quality of the four Internet TVs, we selected the main part of the photo for one by one, and the static photos were more suitable for displaying the layering, details and color accuracy. Because OLEDs are rather special, and the price is relatively high, so the subjective experience part, 3 evaluation engineers more for the price of similar LCD products for comparison. 
UHD video: Coexistence of advantages and disadvantages of OLED TVs
Relatively speaking, the new generation of forces (internet TV brands) lack of accumulation of display technology, hardware design experience is not enough. However, the research and development of Internet TV brand hardware is extremely aggressive and has made remarkable progress. We have seen through UHD 4K content a lot of how they have accepted this great test. 
Static Experience True Feeling Sharing
The gap between OLED and LCD is huge. The overall picture performance of Cool Open T55 OLED makes us quite excited, but the weaker brightness performance can't really show the outstanding details of OLED. Micro-Whale TV 55-inch Pro has a balanced overall performance. There is no obvious flaw, but there is no one that can conquer the crowd. It is a safe choice. The LeTV 4 X55 Curved Commemorative Edition does not represent the performance of the retail version. However, the light leakage has led to poor image quality and the color performance has taken advantage of the Samsung 4K panel. Millet TV 3 55-inch pay attention to the importance of the backlight system, the screen layering tight OLED, bright color to please the eye, the color "Tai Chong" problem can be resolved through set, of course, if you like this full attack The color can be defaulted.
HDR technology measured: OLED is not for whom
In 2016, HDR technology has become a hot spot in the TV field. First of all, it must be acknowledged that HDR technology is indeed an excellent display technology. However, this technology is not as simple as everybody imagines, and it is not just anything that can play an HDR role. Although the products of the four comparisons in this round do not all support HDR technology, we compared the HDR test material and the results are somewhat meaningful... 
To reiterate, HDR is a useful display technology, but the conditions for its entry into force are somewhat harsh. More importantly, to achieve the desired HDR effect, the hardware performance requirements are not so easy. Think of a LCD TV with poor light leakage control. How do you show the HDR effect? Must be greatly discounted. Here we can draw a conclusion that we cannot believe that low-priced HDR TV products have little meaning.
Another conclusion is that HDR effects of a qualified OLED TV product should be better than LCD TVs because no backlight can display true black, and LCDs relying on the backlight system cannot show real value no matter how excellent the black control is. In the sense of blackness, this is the gap of the times. However, through some actual measurements, excellent LCD TVs equipped with HDR can also effectively improve the picture quality performance, but the prices of such products are often very expensive.
Comparison of chip specifications: MStar top 6A938 chip smart experience: pure Internet TV is more willing to lay down the hardware
In addition to the value-for-money advantages of Internet TV, the experience and service is the core of the real competition. LeTV is relying on LeTV.com to launch TV products and succeeded. Xiaomi invests in iQiyi as its second largest shareholder. Behind it is the Chinese Culture (CMC), Internet giants Alibaba, Tencent, and integrates a wide range of high quality upstream content resources worldwide. Cool open is in-depth cooperation with Tencent video, including HBO drama service and NBA event broadcast service. 
Operating system: Three testers have something to say
The system experience is a very subjective feeling, but most people's feelings are actually more consistent. For example, the evaluation of the Apple iOS mobile phone system is relatively close. In order to get a more just result, three testers of TV channels collectively experience and Explore and strive to give you a most accurate assessment. 
Exclusive video content: Xiaomi no sports layout video content: exclusive resources is the king
The Internet TV brand's entry into the television industry relied on "content is the king". Therefore, the performance of each video in the mainstream video resources is not much different. The popular TV shows can be seen by everyone. The video resources are too rich and not rich. So important. Therefore, in terms of video content, the ratio is still exclusive resources, this part is the real sense of the core content competitiveness. 
Uncharted 4 (Uncharted 4) is on the market for sale. This is an exclusive game for the PS4 platform. Other platforms cannot play it. To play this top-level masterpiece, you must purchase a PS4 game console. This is the exclusive meaning and value. The author has in-depth exchanges with a number of TV manufacturers. The self-produced content of this major brand will still focus on the layout, and strive to use powerful exclusive resources to attract more consumers to buy, the era of content is king.
Important additions: surface, PS4, sound quality experience dynamic contrast (matured and practical, but please choose to close if necessary)
Cool open T55 OLED passive light source features unlimited contrast advantages, without the need for dynamic contrast technology, Le Super 4 X55 Curved temporarily due to the relationship between the works of the commemorative version of the discussion. Micro-whale TV 55-inch Pro and Xiaomi TV 3.5-inch dynamic contrast technology performed very well. The dynamic backlight is fast and linear, which can effectively enhance the visual experience. 
Audio experience supplement (the quality of the picture and the sound quality have a practical significance, Xiaomi independent speaker has a significant advantage) 
How to choose the surface and plane? (must recognize the "emperge" surface more presence) 
Summary of results: four high-end TV worth buying
About 4 55-inch Internet TV results
Here, we may wish to review the criteria for evaluation that were developed before. This standard is based on product strength and purchase value. However, the needs of users are not static, so you can choose according to your own preferences. Strictly speaking, individual differences in the same model are normal, and it is not uncommon for the difference to be about 10%. Plus, LeTV 4 X55 Curved is not a retail version. It is only a monumental version of the project. Therefore, the following results can only be used as reference.
Horizontal evaluation evaluation specification 
Cool open T55 OLED - for the pursuit of new display technology and high-end users (9999 yuan)
Cool open T55 OLED metal body, fabric speaker and walnut base with a very tall, OLED picture quality is excellent, but this product failed to show the advantages of the dark details, coupled with the lack of brightness so deducted scores. As the first OLED TV in million, the overall performance of this product is still satisfactory, there is no obvious weakness, which provides practical protection for this most affordable OLED TV, recommended for the pursuit of new technologies and cost-effective High-end users.
Micro whale 55 inch TV Pro - recommended for users who like to watch sports events (JINGDONG less than 3900 yuan)
The whale 55-inch TV Pro has a balanced performance in all aspects. It is a very safe choice. The highest score for content resources is due to membership fees of 199 yuan/year, which is a lot more than competitors. The selling point of this product is the independent image processing chip, in addition to the picture quality improved to a higher level, can effectively eliminate the smear problem caused by the LCD, the official defines it as the European Cup watching artifact, plus Jingdong platform discount The premium price is recommended for users who like to watch sports events.
LeTV 4 X55 Curved - recommended for users who pay attention to surface experience and the pursuit of high performance (4999 yuan)
LeTV 4 X55 Curved as the cheapest on the market 55-inch curved 4K TV, while carrying the best MStar 6A938 chip design, itself is a very cost-effective choice. What we got was a commemorative edition of the project. The work was relatively general and the light leakage seriously believed that the official retail version could be significantly improved. This product uses Samsung's original curved screen, flagship TV chip, Harman Kardon speaker, can fully meet the needs of the vast majority of mainstream users.
Millet TV 3 55 inches - quasi-high-end users pay attention to audio and video experience (3999 yuan +200 yuan freight)
Millet TV 3 55-inch has always attached great importance to hardware technology, powerful backlight system to bring outstanding black performance, and independent speakers make it in the audio and video experience outperformed competitors a grade, highly acclaimed MIUI TV system easy to use Excellent sexual experience, 9.9mm ultra-thin metal body and solid workmanship left a good impression, although millet TV needs to pay extra shipping, but we think this product still has a high purchase value.

7 major project authorities compare four 55-inch Internet TV Hengping
The TV boot rate is getting lower and lower. When traditional TV brands are unable to understand this, the keen Internet brands smell the opportunity to enter the television field. With the new product image of “young hipsters, content is king, and experiencesâ€, they bring a burst of TV industry. For a long time, the breeze that caught the attention of users and the internet TV brands that caught the user's pain points quickly gained a firm foothold in the television field. At the same time, it also provided a relatively correct direction for the transformation of traditional TV brands.
Four high-end 55-inch Internet TV Hengping
The results of the latest market adjustment show that the attention of Internet TV is beyond expectation, and traditional TV brands need to be alert to these “newborn legionsâ€. However, in terms of product reliability and after-sales service, people still trust traditional TV brands. Fortunately, the current well-established Internet TV brands do not suffer from these drawbacks. This is what we want to compare today's cool open, micro whale, LeTV and Xiaomi. High-end Internet TV
Cool open, micro whale, music, and millet “gather togetherâ€
Cool open T55 OLED (9999 yuan): As the Internet's first OLED TV, very historic. As a new era display technology, the CoolOpen T55 OLED has many physical advantages that LCD TVs do not have. The rich colors and zero delay are very suitable for PS4/XBOX ONE game players and are also suitable for watching European Cup and NBA playoff sports. Event, 1080p resolution can meet the needs of most scenes, is a rational high-end choice. Topcon BM-7A Test Instrument
In order to more accurately evaluate the differences between the three segments of Internet TV, we need to digitize the conclusions of each test. When faced with projects such as appearance, subjective picture quality, sound quality, and experience of use, we will average through three professional editorial evaluations. . Next, let's take a look at the scoring system for this horizontal evaluation. Horizontal evaluation evaluation specification
TV as an entertainment terminal in the living room, video and audio experience is undoubtedly the core part of TV testing, so design, workmanship, materials, screen and audio testing accounted for 60% of the total assessment of the relatively reasonable, only 45% here because of Internet TV Specificity, we deliberately set aside 10% of value-added items. Hardware specifications are the basis of intelligent experience, and the quality of the system directly affects the user experience, which accounts for 30% of the score. Four high-end 55-inch Internet TVs compete on the same stage
Coocaa is an Internet TV brand owned by Skyworth, a well-known brand, and has extensive experience in hardware manufacturing. The T55 OLED is a cool flagship product, and its product design and work materials (wooden bases and high-end cloth speakers) are all excellent. Cool open T55 OLED is a product to enhance the brand image, in addition to 7mm thickness can not show the advantages of OLED technology, the design is indeed impeccable in all aspects. LeTV 4 X55 Curved frame is relatively wide (silver white design will interfere with the user's line of sight)
In contrast, it can be seen that only LeTV adopts a silver-white border design, and the remaining three are all dark-colored designs. In fact, this is right. Dark-colored borders can allow users to focus on the screen itself without causing the user to look away. Disturbance, when we compare the picture quality in the darkroom, only the happy silver border caused us annoyance. In addition, as far as work materials are concerned, there is a gap between LeTV 4 X55 Curved and the other three. Hopefully, this is only the relationship between the works and the commemorative edition. Comparison of instrumental analysis results
Low OLED TV brightness
Obviously, compared with LCD products with a brightness of 350 nits, the brightness of CoolTV T55 OLED TV is at a disadvantage. This is quite normal, because OLED display technology has just started, and each technology is not yet able to handle this technology very well. Brightness performance takes time to improve. The brightness of the micro whale is not the lowest among the three LCD products, but the independent image processing chip does play a role, and the dynamic contrast is hidden deep and difficult to detect. It is more pleasing to see LeTV's transparent and bright screens. Millet looks relatively natural, and the excellent black field performance results in an ideal picture quality. Color contrast
In terms of color, there is no doubt that the T55 OLED color performance is the most intense. Over 100% color gamut coverage may require users to spend some time to adapt. In terms of LCD, all three products have shortcomings. The sensitive dynamic contrast of the micro whale weakens the bright color performance; the high brightness of LeTV also affects the accuracy of color; the level of the millet picture is still gratifying, but the color display is too garish , not soft enough, such as the MIUI TV main interface under the red is a little dazzling. Poor OLED dark details
Cool open T55 OLED TV's color performance, detail performance and screen layering is very amazing, this visual experience and LCD are fundamentally different, fly in the ointment is that the lower brightness also lost some shadow detail. LeTV is bright enough to restore more details of the screen, but the screen is less layered. There is little difference between the micro-whale and millet as a whole. There is a slight advantage in the color and texture of millet. OLED interpretation of the real "black"
Because there is no interference from the backlight system, the cool open T55 OLED displays the purest black color, and the performance of the other three LCD products is similar. In this black-and-white-based video, the white balance ability is the most tested. Fortunately, these products are fortunate This is a good performance. The LeTV Ultra 4 X55 Curved commemorative edition is over-highlighted. If the retail version is also the same, it is recommended that you reduce the dot brightness slightly. The performance of the Micro Whale TV 55-inch Pro and the millet TV 3 55-inch is similar, and the millet black display is even more profound. Liquid crystal + HDR effect is inferior to OLED
LeTV 4 X55 Curved explicitly supports HDR technology. Millet TV 3 55-inch actually supports HDR technology (officially low-key). However, HDR technology "blacker places are brighter and brighter places are brighter." This feature destined for OLEDs. It is the most ideal carrier, and LeTV, which has more serious light leakage, has failed to use HDR technology to achieve "repression" of micro-whale TV. It is seriously doubted that the Engineering Commemorative Edition has not abandoned HDR technology. MStar 6A938 - 2016 flagship TV chip
Cool Sky is an Internet TV brand owned by Skyworth. It is more or less inconsistent with traditional brands. Microwhales, LeTV, and Xiaomi are more purely Internet TV brands. These three companies are willing to spend more on smart hardware. The entire series of MStar 6A828 high-end chips, LeTV is the world's first TV manufacturer to use the latest flagship 6A938, millet TV 3 55 inch was listed last year when it was also the strongest 6A928 flagship chip. 55-inch Internet TV core specifications
The cool-on T55 OLED MStar 6A918 is not new, but the resolution is only 1080p, so this product is a good boot speed, hierarchical menu switching, photo switching, video loading and playback speed is also very good. Little whale, LeTV and Xiaomi's control experience is very smooth, and there is no stalling at all. If you like to play big games on TV, the MStar 6A938 that LeTV is equipped with is the most powerful. Next, we must focus on the television system. Cool open TV system (Cool open system 5.0)
Cool open T55 OLED TV uses Cool Open System 5.0, which has certain advantages in boot speed, operating speed and update speed. This system uses a modular classification, and the horizontal layout design is also very simple to operate. At the same time, the operation path is short and the classification is clear at a glance. Press the remote control home button in any scene to achieve the effect of seconds. However, the user's personalized settings are slightly insufficient. For frequently-used APP users, they need to send desktops to add TVs. Micro Whale WUI TV System (WUI System)
The WUI on the Whale WTV55 Pro has re-optimized the Android system, and has made some improvements in fluency and responsiveness. The main interface uses a more flat vertical waterfall flow layout, and all the information is presented on one interface. However, the information presented by the vertical layout is a bit complicated, and it would be even better if the details were further categorized. My TV on the top of the main interface of the system can also add favorite channels and functions by itself. LeTV Super TV System (EUI5.8)
LeTV 4 X55 Curved uses the EUI5.8 operating system. The overall optimized operating system has excellent fluency, without any slow response or stalling. The layout of the entire interface is neat and tidy, which increases the convenience of the user in the operation, and the portal you want to search is clear at a glance. However, due to too many sub-pages, users also need a certain amount of time to become familiar with and adapt to each content category. This operating system also provides users with desktop management functions, users can add and layout through preferences. MIUI TV System
Millet TV 3 55 inches based on the latest MIUI TV operating system, the main UI interface is refreshing, secondary UI interface is full of vitality, compared with the cold content resources are more sentimental, the overall control experience is flowing, the user learning cost is very low, The level of easy control at all ages is still worthy of recognition. It is worth mentioning that the ecological layout and experience of the Xiaomi App Store was unanimously endorsed by three testers. Cool TV can directly watch Tencent NBA playoff live games
Micro Whale TV exclusive TVB, BBC, VICE and other key content resources
LeTV super TV exclusive "super" events (and a large number of homemade drama)
When the sun’s descendants are hottest, only the millet TV can directly pursue the drama.
Cool TV and Micro Whale both have deep cooperation with Tencent Video. Among them, Cool Open also supports live NBA games, while Micro Whales have content resources such as TVB, BBC, and VICE. LeTV directly buys out Super League events. Millet TV enjoys everything directly. Iqiyi’s exclusive resources (millet is the second generation shareholder of iQiyi), and the descendants of the extremely hot sun have gathered a lot of popularity for Xiaomi TV. Such popular programs as Qiqi said that it is also exclusive for Xiaomi TV. PS4 exclusive masterpiece of the mysterious waters 4 (open dark shadow details of dynamic contrast performance)
However, when I connected to the PS4 game console and found that the flickering feelings affected the experience, the dark scenes appeared darker and caused the details of the game screen to be difficult to present. If you plan to use a TV product to connect the PS4/XBOX ONE game console equipment, please Be sure to turn off dynamic contrast technology in your settings. Millet split host (smart chip, interface design, stand-alone speaker)
Entering the UHD 4K era, the picture quality has been greatly improved. Only the simultaneous enhancement of the audio quality can really enhance the audio and video experience. Many consumers only pay attention to whether the 4K panel is really 4K but ignores important audio parts. Fortunately, Internet TV products generally pay more attention to audio, cool open and the performance of micro whale is relatively good, LeTV Harman Caton built-in speaker effect slightly better, but the best is the millet split independent speaker, almost reached At the home theater level, potential consumers with a particular focus on audio experience should focus on high-end split TVs. Cool open T55 OLED / Le super 4 X55 Curved curved design
Surfaces are the current hotspots, but many users have questioned that surfaces are only suitable for a small number of people, and a multi-person experience has to be flat. This kind of thinking is to a certain extent not wrong. First of all, for most users, we have to admit that the surface experience of the emperor TV is really better than the plane, but the audience that can take care of it is not as flat as it is. Therefore, the choice of surface or plane is not a problem. The author has contacted a large number of curved TVs. Users who like curved surfaces recommend that they choose 65 inches or more. The shock experience is much stronger. Final score column
