10 project authority comparison! Six 55-inch Internet TV Hengping

On September 19, the comprehensive Hengping review was officially launched!

2017 six 55-inch Internet TV comprehensive Hengping

● Why a Hengping project is divided into 3 parts

Why do we split this TV review into three sections? First, smart voice technology is a major trend in this year’s TV industry. Almost all internet TVs are based on HKUST’s technical support. We want to understand if there are significant differences and whether they offer real convenience for users. Regarding the disassembly part, internet TVs can be sold at relatively low prices. What is the reason behind that? Are there cases of cutting corners or overhyped features? With these questions, we decided to dismantle some of the internet TVs to analyze their quality.

● Why did we choose to conduct the Hengping project now?

Every year, the peak season for home appliance sales approaches. During events like National Day, Double 11, and Double 12, TVs are always key targets for sales. Among many specifications and brands, combining the most developed internet technology with e-commerce channels makes internet TVs one of the most competitive product categories. Hence, we organized this cross-project review to help you make informed choices when buying an internet TV.

● Why 55 inches?

Compared to 43-inch models, 55-inch TVs have noticeable upgrades across various dimensions. For example, resolution increases from 1080p to 4K. The smart chip jumps from entry-level to top-tier, wide color gamut, and HDR technology are introduced. This "golden size" truly compares quality and experience.

● Why these six products?

In this Hengping review, we deliberately selected six flagship 55-inch internet TVs, including Hisense VIDAA LED55V1UCZ, Xiaomi TV 4 55-inch, Mini Whale TV 2nd Generation 55-inch, Visible X55Q, Cool open 55A3, and PPTV N55. At first, we invited many internet companies, but only these six brands dared to prove themselves. After extensive testing, dismantling, and writing, today's Hengping article was finally released to help everyone buy internet TVs during the 11th.

Scoring standard announced: Fair, just and reasonable

● Scoring system: in line with the principle of fairness, fairness and reasonableness We will test product appearance, image quality performance, sound quality performance, system UI, content resources, and the overall performance of price and product. To display results more intuitively, four professional editors will score each product and average them for a comprehensive comparison.

Hengping scoring rules

Design occupies 15 points. The appearance part of this Hengping review will focus on whether homogenization can be achieved. In addition, the inspection will be conducted through materials of the frame, backplane, and base, as well as the technology of the frame. Video and audio quality should occupy 40 points as the core of television. The quality part is subdivided into objective data and subjective image video quality tests. Objective data will be tested from gamut, contrast, HDR peak brightness by Topcon BM-7A professional test equipment. System operation experience and content resources total 20 points, and newly added voice and dismantling components each occupy a large portion. The overall performance of the final product price and the product itself occupies 10 points.

The instrument used in this test is the BM-7A luminance colorimeter produced by Topcon to measure the chromaticity coordinates of 4 TVs in different colors, and calculate the contrast, color gamut, color temperature, color saturation and draw the corresponding values. Corresponding color characteristics map 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.

● Design: Ultra-thin and shocking visual experience Outstanding product design is more likely to be loved and recognized by consumers, so industrial design is particularly important in the business world. The thickness of the fuselage, the material of the frame, the shape of the base, and the difference in color matching all determine whether the television appearance can meet the requirements of consumers. Ultra-thin, metal, and narrow borders, which have been used in mobile phone products, have become more and more used by TV manufacturers in their own products as technology continues to advance and the television industry has developed. In this Hengping review, we have previously unveiled the six TVs in an unboxing experience. It is heartening to note that these six televisions have been greatly improved in terms of workmanship, materials, and product highlights.

The thickness of the side of the frame is 8.9mm, which is not the thinnest in several Hengping products. The use of the all-metal one-piece molding process has given this TV a lot of extra points in industrial design, and it seems to be very good for eyeballs, while stability and protection are also guaranteed. The circular switch in the lower right corner of the TV is full of features.

The second-generation 55-inch micro whale TV is an upgraded version of the previous generation WTV55K1. The appearance of the WTV55K1 is basically an extension of the previous generation's design style. Although the surface does not seem to have a place of color, but the savor, the minimalist design is also in line with the current young The aesthetic concept of the generation, while the design of hardness and softness makes the hardness of the metal material blend well with the softness of vision, and the color of the space gray color is steady, which is also in line with the low-key and steady style of the brand.

It is worth mentioning that this TV has also won the "China Good Design" Gold Award, a new international design award for China launched by the German Red Dot Awards. The review process is responsible for the entire process from Red Dot, so this award is still very good. With ** gold.

See still X55Q is still see the high-end "Hwan look" series, but also to see the first curved surface TV products. With a 4K curved screen, the overall design of the 4000R's gold curvature follows the currently popular minimalist design style. The silver+gray color scheme looks more concise. The large silver-white all-metal material of the machine has successfully created a sense of fashion and technology. The inturned base design cannot be defined as “beauty” in the traditional aesthetic, but the effort to get rid of design homogeneity is obvious. The independent heavy bass cavity highlighted on the back makes us look forward to the sound quality.

Coolo 55A3 TV continues the simple design style of the previous generation A2. The extremely narrow border enhances the proportion of the screen and provides a broader view. At the same time to join the integrated molding technology, in the product details to see the cool open this product's production sincerity. The thinnest part of the machine is only 7.9mm, slim and tough. The back of the large area of ​​the use of metal materials, black looks very tough. With 2 suspension independent subwoofer + 6 JBL audio, power amplifier configuration is still very high-handed.

Different from the past, the 55A3 has a black overall color and a front panel with a gray linen material. This undoubtedly improves the high-end attributes of the entire product, and the grades are immediately upgraded. The iconic orange cool logo in the lower right corner of the screen reflects the youthful and energetic side.

The style of the PPTV N55 TV and the previous PPTV TV has been changed. The overall black body with a gold mirror base has exposed the high-end quality. The double-sided seamless bending process is applied to the front frame and side frame of the TV. Compared to the splicing process, the seamless bending process is higher in terms of technical difficulty and manufacturing cost. At the same time, the N55 frame material also uses aviation-grade aluminum. Shaped material, the material can be said to be nothing. The combination of black borders is also very easy to use. It does not interfere with the user's eyes when the user watches. At present, many television products have adopted light-colored borders, which will affect the viewing experience.

Internet TV brand positioning young market, so in the industrial design is usually more stylish atmosphere, because the participating in the Hengping six models are the flagship models of their own brands (except micro-whales), so the design and workmanship materials are counted Draw a hand. With an aesthetic after 80, cool open A3 positive sense of a more level, side view of millet TV 4 55 inch ultra-thin 4.9mm is indeed very amazing, this link can not open the gap.

● Objective data: Backlight system is critical for LCD

Instrument testing is an indispensable link in the Hengping review. In this link, we put six TVs in the same scene and adjust the picture quality to the factory state. Although the entire testing process was conducted in a dark room, the test results inevitably produced errors, so we averaged after repeated tests to minimize errors.

NTSC color gamut: Micro whales win with a slight advantage

The wide color gamut means that TV can display richer colors and the vividness of the screen has been significantly improved. Due to the increase in the types of colors, the colors in the screen are excessively natural, and distortion and color patches are effectively avoided. More kinds of colors make the picture level more distinct and able to show more details and closer to real results.

These six TVs are all high-end flagship series under the brand, so they all have high attainments in color gamut performance, and most of them have already achieved high color gamut standards. The whale TV's 2nd generation 55-inch NTSC color gamut value is 91.06%, which is the highest among the six TVs. Hisense VIDAA TVs with ULED technology also performed well. The Coocaa 55A3 sacrifices the high color gamut by filtering the blue spectrum of anti-blue light.

However, I still want to explain that the number of colors increases, although the screen is more beautiful, but the displayed colors are not necessarily accurate. High-gamut televisions have increased the variety of colors and brought greater burdens on the control of color. If the color control is not accurate enough, the displayed image will still be distorted, and it will be far from the true color. Raising the color gamut is of course a good thing, but it should take into account the control of color so that rich colors can have a real effect. Therefore, the quality of the image depends on the manufacturer's tuning.

Static contrast: Hisense VIDAA light control performance amazing

Emphasize that color gamut is not as high as possible, especially after NTSC color gamut exceeds 95%, the current level of Internet TV brand is Hold, due to their respective high-end flagship or quasi-flagship models, measured color The domain value results are good, cool because the backlight started anti-blue light processing, resulting in a poor color gamut, but also in the pass line. In terms of contrast, the technical advantage of the traditional manufacturer Hisense stands out from the crowd and it has no friends.

● 4K picture contrast: color and brightness control is the most critical

The six products that participated in the Hengping review were all 4K (3840*2160) resolution TVs. In the 4K static image test, we will analyze from a variety of perspectives including color accuracy, color transition, and contrast. In the local 4K image test, after the author shot a large number of materials, according to the type of intentionally selected the following three representative pictures, the entire shooting process is in a darkroom environment.

● 4K video contrast: the accumulation of display technology is very important For a TV, if it wants to have excellent picture quality, then it must have two natural conditions, one is a panel with excellent picture quality, and the other is a mature picture quality display technology. Both are indispensable. The six TVs participating in this Hengping review, in addition to Hisense VIDAA, other brands are lack of accumulation of display technology. However, after testing with objective instruments and 4K images, we are also looking forward to these TVs. Here we let the six TVs pass the test with 4K video.

From the light and shadow control, contrast effect of light and shade point of view, overall, Hisense VIDAA TV overall look more real, dazzling sunlight, the black field around can also be a natural presentation of the original appearance. The light and shadow control of the microwhales can be said to be no less than Hisense VIDAA. Looking at Shang and PPTV, the overall performance is similar, and the color transition and light control performance are quite satisfactory. The coolest screen is the softest, and the lack of brightness does not excessively weaken the color performance. Millet clearly brings more dark detail, but excessive brightness makes the picture lack authenticity.

● HDR video comparison: control is not good

Among various display technologies, HDR is the only hot technology direction in which all brands participate. With the development of HDR technology, TVs that do not have HDR may not be able to parse or watch HDR sources in the future. TVs equipped with HDR technology can significantly enhance the screen display contrast and color range. The bright part of the screen will be clearer, the dark part will have more depth, and the layers will look more distinct. The increase in color accuracy will also make the color look more pure. And bright.

We know that the greatest feature of HDR TV is that it has a very high dynamic range of brightness. The brightness range that can be observed by the human eye is 10^5 cd/m2, which means that the higher the TV peak brightness, the more obvious the HDR effect will be. However, in the previous instrument tests, we also tested HDR peak brightness of six TVs, but none of them exceeded the static brightness peak. This led us to question the HDR quality of the six TVs.

The high dynamic range is just the basis of HDR control for very high/low brightness and is the basic condition for realizing HDR technology. With this limit of brightness and darkness and level control, you can express your colors more clearly and present richer and more realistic colors. In the HDR color comparison, the color performance of Hisense and Xiaomi is more real; the look is still more prominent in the expression of layered feeling; the performance of the micro-whale and cool-opening is quite satisfactory; while the PPTV seems to be pleasing in color, but in fact the color saturation is slightly overdone.

The popularity of HDR technology, Internet TV brand will certainly not let go, but in fact HDR technology is very deep, Dolby Vision, HDR10 various standards. This technology can indeed significantly improve the quality of the picture, but it is limited to top-end TV products. It is a bit funny to talk about the HDR quality of a few thousand Yuan Internet TV. From the actual measurement point of view, the HDR test is still quite a lot of problems, even if the support has not seen the picture quality has improved. In a word, Internet TV brands do not have to care about HDR technology and have little significance.

● Core hardware: annual flagship chip fight

The importance of core configuration for smart TVs is self-evident. As with computers, higher configurations will result in a smoother operating experience. The TV chip has more important responsibility than the computer. It plays a role not only in fluency but also in the quality and sound quality of the TV. Since 2015, more and more manufacturers in the Chinese TV market have started the hardware PK mode. The six TVs participating in the Hengping review, four of which all use the annual flagship chip MStar 6A938, significantly enhance the overall performance of the TV.

Comparison of six Internet TV hardware parameters

In general, the six TVs did not open a large gap in the core configuration. In this round of Internet TV ratings, four TVs have adopted the annual flagship chip configuration, which is definitely the most fierce competition. . From another point of view, it is reflected that Internet companies like to spare no effort in the hardware configuration, so as to make up for deficiencies in the display technology and other aspects.

● Operating System: Strengths of Internet Vendors

Hisense VIDAA LED55VIUCZ TV is still VIDAA smart operating system, based on Android system depth customization, while providing rich content while also achieving a key in-depth direct. The system adopts a horizontal layout for the main categories, and becomes longitudinal when it enters a sub-page. The idea is relatively clear and the content is numerous but clearly organized. The VIDAA system also supports voice control. The "Hisense TV Assistant" can also control the TV with a mobile phone, which combines both intelligence and ease of use.
