4K smart TV which brand is good 11 4K TV Hengping Introduction

4K smart TVs have become synonymous with high-end televisions in the smart TV market. Faced with the continuous improvement of high-end smart TV technology, 4K smart TV products are also flooding the smart TV market. The face of many businesses provide 4K smart TV products which brand the best? Xiao Bian provides 11 horizontal contrast evaluation of 11 TVs for everyone to help you better choose!



Compared with last year, the 4K TVs that were launched in 2014 are basically equipped with larger screens, equipped with more humanized smart operating systems, and have more abundant functions, and can also realize interactive applications using mobile phone tablets. At the same time, as the production technology of 4K ultra-high-definition LCD panels has further matured, there has been greater improvement in terms of color, sharpness, and details of the picture. In addition, due to the large-scale mass production and competition of upstream panel makers, the price of TV has also been on the decline, and the price of many new products has been almost the same as that of Full HD TVs.

It can be said that regardless of whether or not you paid attention to 4K television before you bought or did not buy, the era belonged to him was really coming! Since we cannot change, what we can do now is to understand him and accept him. However, the problem has also come. The function and design of 4K TVs are very different. The price span is from 2,000 yuan to tens of thousands. Why is there such a big gap? Faced with numerous and complicated markets, we feel that it is necessary to make a comprehensive comparison of mainstream hot products and tell you the most realistic results to see who is best for everyone to buy.


Hengping product model and price

The horizontal comparison evaluation selected 11 models of 4K ultra-clear TVs currently being sold, and the price range includes high, medium and low products, which are suitable for almost all consumers. Contrast content will include product appearance, color quality, control experience, video resources and smart applications, all of which come from the IT168 evaluation center's data, all of which are authentic and authentic. (The following table is based on domestic brands, Internet brands, and foreign brands.)



Contrast evaluation summary: Through all the test links and comprehensive test results, we recommend four products with different price ranges that are worth buying.


5,000 yuan 4K TV Recommended: Music as X50 Air TV & Lenovo 50S9 TV


Recommended reason: Music as the biggest advantage of X50 Air is 4K video resources, greatly leading other contrast models, can give full play to the power of 4K TV, while the price is relatively reasonable, there is no obvious short board, it is worth buying. The reason why choose Lenovo 50S9 is to value its innovative concept, unique color shell and transparent base, to meet the needs of different users, while the unique minimalist intelligent remote control allows more convenient control, coupled with the fluency of the intelligent system Advantages of ease of use have continued, recommended purchases.


More than 5,000 yuan 4K TV Recommended: Skyworth 55G8200


Recommended reason: The biggest advantage lies in the picture quality performance. It can be said that it is the only wide color television below 10,000 yuan. The color performance is very good. At the same time, it is quite outstanding in appearance design and intelligent systems. It has a wealth of online video resources and mobile screen games and entertainment, etc. It is very practical and can bring users a new smart experience.


Million or more 4K TV recommendation: Sony 55X8500B

Recommended reason: in the appearance, quality and sound quality are called top, although slightly inferior and Japanese brands Panasonic TH-65AX800C, but taking into account the difference between the two nearly 10,000 yuan price, we still recommend the Sony 55X8500B. However, we also want to see that this TV is still unsatisfactory in terms of intelligence and applications, and is suitable for high-end user choices that focus on image quality.


Written at the end: The Japanese brands represented by Panasonic and Sony are mainly represented in the color part of the screen. This is the most important part of the 4K TV, but it is relatively general in the software and the functional part and still needs improvement. And many products on the design have begun to break the tradition, using a new color frame and alternative design, can better integrate into the modern home environment. The TCL L55E6700A-UD and Lenovo 50S9 are relatively special. They regard the game function as the main direction and hope to open up a new field for smart TVs to attract more game players. This is also one of the development trends of TV in the future.


However, for these 11 4K TVs, although they are all 4K TVs, in fact, online 4K video resources are not very rich at present, which is related to the popularity of 4K as a whole, but we can still very happy to see LeTV. Sony and other vendors are planning to invest more in the production of 4K sources. From the current point of view, the Lexus X50 Air is the most complete in terms of 4K online sources and ordinary sources.

What is a 4K TV?


(Because our article is for all friends who want to understand 4K TV, we still have to introduce the concept of 4K TV. Of course, if you are someone who knows about 4K, you can skip this page.)

In fact, 4K TV has a 4K ultra-high definition resolution, which means that the TV screen has reached a physical resolution of 3840 2160, which is equivalent to doubling each of 1920 1080 (1080P) horizontally and vertically. It is still the standard 16: 9 specifications. We can use a simple and easy-to-understand example to explain that 4 full HD screens are seamlessly connected in four-square blocks to display 4x full HD resolution images. This is the difference between 4K and full HD.



4K has 4 times the picture quality performance of 1080P


We can only see the difference from the pixel, 1366 768 HDTV can display 1 million pixels, 1920 1080 is only about 2 million, 4K TV pixels reach more than 800 million, the biggest advantage is the fineness of the image display A very substantial increase. In general, the 4K TV we are talking about is a TV with a resolution of 3840 2160 resolution.


The status of 4K TV

In the current 4K TV market, there are mainly three “groups”: 1. Domestic brands represented by Skyworth, Hisense, Changhong, TCL, and Konka, relying on their reputation, brands, technical channels, and after-sales advantages accumulated over many years, Combining the latest smart operating systems, it still occupies the leading position in the market. Second, the joint venture brands represented by Sony, Samsung, LG, and Sharp are focused on the high-end market, and guard the high-end market through a series of the latest display technologies and superior quality; In recent years, emerging Internet brands represented by Lenovo, LeTV, and Xiaomi aim to sell their own online services via TV. Therefore, they do not need to rely on hardware to make money, so that they pass ultra-low prices and Internet-style. The promotion of these products has high popularity.


Our Hengping evaluation is to select the model with the highest degree of attention and the most representative model from the above three camps, and to give the user the most objective shopping guide through comparison.

Test method description

After a preliminary understanding of the 11 TVs of this Hengping review, the next step is to introduce the direction and specific methods of evaluation. The Hengping Review will comprehensively evaluate a 4K TV from five aspects of design (including workmanship, humanized design, interface, etc.), image quality (including panel performance, light and dark details, etc.), control experience, video playback, and smart applications. . The test instrument uses a test instrument Topcon BM-7 and a digital multimeter.



Topcon BM-7


The biggest improvement of 4K ultra-high definition TV compared to full HDTV is the fineness of the picture. Therefore, in this comparison test, we also focused on the benchmark performance of TVs and the effect of 4K ultra-high definition video playback. Their weight is also relative. biggest. In addition, since the current TV products have all been integrated into the intelligent elements, the fluency, humanized design, and online video resources of each brand TV are also the focus of our evaluation.


Appearance process comparison

For the black and silver design of LCD TVs, you are already tired and unfavorable with the ever-changing home environment. At this time, what we need is a LCD TV with a colorful shell design. Fortunately, the manufacturers did not disappoint us. There are already a variety of LCD TVs on the market for us to choose. The first is the appearance of the 11 4K TVs. Our comparison projects mainly include four aspects: industrial design, body material, detail workmanship, and interface richness.



The above is a comparison of the appearance of the 11 TVs. Viewed from the front, basically all of them are based on the current use of the most popular ultra-narrow frame design, but different in the base and the bottom frame, including Xiaomi TV 2 and Skyworth 55G8200. Champagne scheme on the front.





Participate in the Hengping TV uses LED backlight source, from the side of the comparison point of view the difference is not large, which Lenovo 50S9 due to the use of overall blue color, so it looks more like some.



Fuselage and detail design


The back is not particularly important for televisions because most of the time is against the wall. However, the cool open U55, Lenovo 50S9, and Changhong CHiQ 58Q1N TVs with non-traditional black backplanes are still eye-catching and have better visual effects than other black back-panel TVs.



Cool open U55 can see the transparent panel on the back






Lenovo 50S9 TV Blue Back and Changhong CHiQ 58Q1N TV Back


Body material, the majority of domestic brand television for cost considerations, are based on plastic materials, only a small amount of metal material applied to the base or the bracket part. Only in the case of Sony-Panasonic and foreign-brand TVs can we see all-metal boxes, but Millet TV 2 is a special case. It also uses metal cut-out boxes that look really upscale.



Millet TV 2 with metal frame


The base, in addition to Panasonic alternative non-base frame design, other brands or have their own characteristics, such as Lenovo 50S9 transparent injection process color base, and TV color matching perfect match, can be said to be one of the most fashionable TV.

Panasonic TH-65AX800C Alternative Base Stand


In addition, Panasonic TH-65AX800C, Sony 55X8500B, Skyworth 55G8200 also comes with a camera that can be remote video.


Panasonic TH-65AX800C and Sony 55X8500B also comes with a camera


In the 11 4K TVs we tested, all models are equipped with a sufficient number of HDMI interfaces, card readers, and USB interfaces, which are sufficient for general home users. Some of the HDMI interfaces support MHL, which can directly support MHL. The mobile phone of the interface is connected, and the content of the mobile phone can be pushed to the LCD TV, and the mobile phone is charged at the same time.


Summary: From the aspect of appearance, 11 4K TVs have ultra-narrow frame and ultra-thin fuselage. Different from the past, the color scheme is more diversified. White, silver, black and even colored shells are used more, and can be better matched with the modern home environment. For the materials used for work, the price is still a decisive factor, and the foreign brands with higher prices are clearly superior.

Comprehensive comparison of control modes

For 4K TV, the convenience of operation is also a very important part. After all, most of them are now smart TVs. After the system is more complex and powerful, it is also very important for ordinary users to get started easily.



The above is a cross-reviewed 11 4K TV equipped remote control, you can see compared to the past, ordinary TV remote control is full of number keys and various function shortcut keys, cumbersome operation, the vast majority of keys will not be used for a long time Instead, it is a smarter remote control that is smaller, lighter, and with fewer buttons. All operations can be performed with just a few keys.



In addition to the basic operations, more and more efficient operation methods have also been added. The air mouse is a good way to control. With the improvement of technology, air mouse has been greatly improved in terms of sensitivity and accuracy, and the user experience is better than the previous product.



The air rat technology of Lenovo 50S9 is very sensitive


In addition, the Lenovo 50S9 remote controller structure is the simplest of the 11 models, only a physical button, which combines the four functions of somatosensory, air mouse, touchpad and voice, so it can completely achieve blind operation, the cost of learning is very low. However, if you want to use shortcut keys or complicated functions, you still need to look at the remote controller before operating it in a short time.



Changhong CHiQ TV mobile phone control more convenient




Skyworth 55G8200 TV supports WeChat access handset control


In the aspect of control methods, multi-screen interaction is also the main direction of development. TVs participating in Hengping basically have the function of interconnecting mobile phones and tablets. The advantage of this is that mobile phones can replace traditional remote controls to achieve various operations while playing games and texts. Input and other aspects have the advantage that the remote control cannot match. This is also the inevitable direction of future development. The actual experience, the operation experience of Changhong CHiQ 58Q1N and Skyworth 55G8200 is better.

Summary: The fully simplified remote control provides more convenient control, while the newly added features such as somatosensory, air mouse, and voice give people a brand new experience.

4K TV quality comparison

The most essential function of a TV is the display. Whose picture quality is better? This test mainly compares the color gamut range, brightness, contrast, and dynamic effects.



After the professional instrument BM-7 test, the specific image quality performance parameters are shown in the following table. When the LED backlight is adjusted to the maximum, the maximum brightness of the Skyworth 55G8200 TV 565cd/ is the best. In terms of color gamut, the Panasonic TH-65AX800C TV is 104% dominant, and the color performance is more vivid and real. In terms of contrast, LeTV X50 Air performed best, reaching 4480:1, but most of the TVs tested did not support dynamic contrast shutdown, so the test results are for reference only.



Panasonic TH-65AX800C has the best color gamut


In terms of dynamic resolution, we mainly use the human eye to perceive the difference. In actual experience, the high-end Sony 55X8500B TV and Panasonic TH-65AX800C TV perform best, basically achieving a dynamic resolution of over 800 lines, but other products are relatively More generally, it is generally in the range of 300-400 lines.



Dynamic picture definition test


Summary: It can be seen from the test results that 11 TVs have their own advantages and disadvantages. In terms of the actual effects of the picture quality, Japanese Panasonic and Sony have significantly better results than other products, but domestic brands also have their own advantages, such as Skyworth 55G8200. The NTSC gamut value is already close to 90%, only behind Panasonic's top 4K TV TH-65AX800C, and the performance is also worthy of recognition.


Comprehensive comparison of intelligent systems

The meaning of intelligence is not as complex as possible, and the key to intelligent control is simplicity. I would like to ask a smart TV. If even the most basic input controls are difficult to achieve, the elderly and children in the family will not operate. What are the meanings of those so-called functions? Therefore, we say that the current intelligence should consider two important factors: UI interface and manipulation experience.

First of all, talk about the user's UI interface, which is also impossible for all smart TV users to bypass. Many of the smart TVs that were first listed have adopted interfaces similar to those of smart phones and tablets. One is that the operation is extremely complicated, and it takes at least five steps to open a program; the other is to display all the applications. In the same main interface, if you want to find a program, you also need to have a hot eye, and the icons have no special customization and optimization. The user experience is very unfriendly.



The 11 4K TVs we tested are all new products introduced this year, so they have reached a very high level in terms of hardware configuration. This guarantees fluency and the actual experience is indeed the same. In particular, domestic brands have been criticized for fluency problems before they have greatly improved, and the products of the Internet brands are already almost the same.



Currently, most smart TVs use the Android operating system and are similar to mobile phones and other products. Therefore, the boot time also depends on the hardware configuration of the TV itself and the degree of system optimization. The important introduction here is that since Sony and Panasonic TVs do not use Android, the boot time is very fast. The boot time of the Sony 55X8500B is only about 2 seconds.

UI layout, basically nothing more than the user's most commonly used video, applications, games, television, set these items, as to compare who is more reasonable, I think it is still based on personal habits and preferences to determine, here List friends who are interested can compare.

Summary: Compared to smart TVs a year ago, this Hengping product has improved in terms of fluency, interface aesthetics, layout and rationality. Overall, the gap is not large.

Video related comprehensive comparison


Current smart TVs generally provide on-demand video on demand (VOD), which is currently the most used feature of users. However, due to the current acceptance of the SARFT Internet TV platform only CNTV, BesTV, South Media, China, China International Broadcasting Radio's CIBN, Hunan Radio and Television and CNBN's CNBN Yangguang Radio and Television Network, these 7 institutions, other Appliance manufacturers can only cooperate with these seven licensed agencies to comply with regulations. Currently, most of the existing smart TV manufacturers also cooperate with these companies.



Online video has to enter through seven licensees


A few days ago, the SARFT's review of content became more and more stringent, resulting in no matter what brand, which models, their built-in video content is basically the same, it is difficult to produce differentiation.

Of course, individual TV brands will still seek breakthrough points. Many smart TVs have an online HD video zone with a resolution of 720p or 1080p. However, there are not many manufacturers that set up 4K zones, even if they have a built-in 4K zone. The number of videos is very small, and even if there are only a few sources, most of them are 4K effects simulated by 1080p video, and there are still big differences from the real native 4K video effects.



After entering the 4K area of ​​LeTV, you can see 217 movies in 4K, and they are all new films.


Relatively speaking, LeTV X50 Air has the most abundant resources in online 4K video. It not only opens up 4K area, but also has a rich built-in film source, which is almost equal to the total number of 4K online sources in the other 10 products. In fact, X50 Air is also the only TV product to purchase online video services separately from the 11 4K TVs.



Lenovo 50S9 Built-in BesTV 4K Area Resources


Summary: Subject to policy reasons, online video resources are not much different from each other. Compared to LeTV, LeTV is more legitimate video resources. Among the 11 4K TVs, TVs with 4K zones are LeTV X50 Air and Lenovo 50S9. LeTV's resources occupy an overwhelming advantage.


Game application comparison

The abundant application of APP is one of the core advantages of smart TV. However, most smart TVs on the market today are facing a large number of applications, but the real killer applications are basically not. Most of them are directly loaded on mobile phones, tablet computers, and other small screen devices. The degree of optimization is not good enough to guarantee the use of results.



Application interface


Of course, Rome was not built in a day. We still have to take a tolerant attitude towards the application of smart TVs. After all, smart TVs have only been available for only 2 years since they were launched, and we have already begun to use products from some brands. I saw a lot of changes from the past.


The first thing to focus on is the TCL L55E6700A-UD, which is the first selling point for the game. It has built a lot of quality and playable Android games with game controllers. Bring gaming experience that was not available in smart TV before.



TCL L55E6700A-UD Video Game Area


In addition, other brands built-in TVs include TV guardians, children's education classes, K songs, weather, fitness, etc., which are more practical programs. Of course, we can also go to the application mall to download.



Application classification




Dance fitness and karaoke applications are also more practical


Summary: The problem of lack of killer applications is common in 4K TVs tested. Compared to TCL L55E6700A-UD TV games, there are still some selling points.


4K ultra HD real shot pictures contrast

Look at the front of the more boring text contrast, the following release a group of real shot 4K ultra-high-definition pictures and video, screen photography is inevitably slightly distorted, but still can be seen through the contrast of different images, the difference in color performance, the richness of details.

Comparison between after-sales and post-investment

In terms of after-sales service, whether it is a joint venture brand or a domestic brand, after so many years of hard work in the Chinese TV market, they have established a very perfect after-sales service system, regardless of their ability to solve problems or their attitude towards consumers. Achieving a very good level can basically be assured.

However, for the new Internet brands such as LeTV and Xiaomi, there are indeed some gaps in the channels and after-sales compared to traditional brands. For example, Xiaomi expanded the number of cities purchased to 243 in the next working year, and many of the cities and towns below the 4th level bought Can not buy, not to mention after-sale maintenance.

In addition, before buying a smart TV, don't be fooled by the beauty of the vendor's promotion, especially the price may not be as advertised. In addition to the TV itself, the cost is also an important factor that must not be ignored. For example, some television remote controllers do not support somatosensory and voice operations. However, in the store experience, special remote controllers are used to demonstrate the effects. It may be very good. It may not be used when you buy it home. Even the most basic games cannot be played. At this time, you need to spend extra money to buy it.



Many video features require additional payment


In addition, a lot of smart TVs have started to implement charging policies. For example, Sony charges fees per movie, but more like pay-as-you-go and annual fees, such as LeTV and Lenovo, need to pay 300-500 per year. Around the cost of the yuan, for example, if you want to watch the latest movies, high-definition video, it can only choose to pay, although not mandatory, but with 50 inches above the screen to see standard definition DVD quality video is still very uncomfortable , so before buying it must be clear whether the need for investment in the later period.


Comparison conclusions and product recommendations

After a number of rich and detailed tests, I believe that many readers can not get so much test data and information in a very short period of time. Finally, we integrate the way we summarize and recommend products.




The Japanese brands represented by Panasonic and Sony are mainly outstanding in the color part of the screen. This is the most important part of the 4K TV, but the software and the functional part are more general and still need improvement. And many products on the design have begun to break the tradition, using a new color frame and alternative design, can better integrate into the modern home environment. The TCL L55E6700A-UD and Lenovo 50S9 are relatively special. They regard the game function as the main direction and hope to open up a new field for smart TVs to attract more game players. This is also one of the development trends of TV in the future.


However, for these 11 4K TVs, although they are all "4K Internet TV," in fact, online 4K video resources are not very rich at present, which is related to the popularity of 4K as a whole, but we can still very happy to see To LeTV, Sony and other manufacturers are planning to put more efforts in the production of 4K film sources, and from the current point of view, Le X50 Air in the 4K online film source and the general film source to do the most complete.
