84-inch super giant screen flagship! LG 84LM9600 first evaluation

[PConline initial evaluation] As early as the end of last year's CES Consumer Electronics Show, LG released its 84-inch 4K ultra-clear TV, and at the end of August at the IFA Berlin Consumer Electronics Show, more brands released its large size , 4K ultra-clear television, which indicates that in the next few years, large size, 4K resolution will become the focus of development of various households, and mainstream home products may also be gradually tilted to it.

LG, which has been providing panels for domestic manufacturers, may be seen as the main promoter of large-size ultra-clear TVs. From the panel specifications of the various 84-inch ultra-clear TVs, the IPS panels produced by LG should be used; We have a chance to see LG's own products this time, and through the evaluation to figure out the true strength of this panel.

● List of product hardware parameters

According to the article provided by LG, the TV has a feature called Dolby surround sound 2.2, in addition to the two major selling points of oversized and ultra clear resolution. In addition, its power consumption has reached 520w, which is worthy of attention.

● Selling point analysis

1, 84-inch large-screen LCD panel

The largest LCD TV currently on the domestic market is Sharp's 80-inch LX842 LCD TV, but this TV is only a full HD resolution screen. This LG 84LM9600 not only achieves the largest LCD screen size in the market, but also corresponds to the display content of four 42-inch TVs, and is far ahead in resolution.

84 inch screen

2, Ultra Definition ultra high definition

As the screen size increases, only increasing the resolution can ensure the clarity of the image, so the logistics resolution of this TV reaches 3840×2160, which is equivalent to the movie production standard. The total number of pixels reached 8 million or more, which is 4 times that of Full HD (1920×1080), and pixels could not be recognized with the naked eye.

UD Ultra HD resolution

3, 2.2 audio system (2.2 speaker system)

The 2.2 audio system consists of two 10W speakers and two 15W subwoofers. The subwoofer can further strengthen the sound system of the UD 3D TV, allowing consumers to enjoy a more vivid listening experience.

2.2 speaker system

In 3D, the UD TV adopts the principle of polarized 3D display, which can achieve 3D display without flicker, and the 3D glasses do not have much volume.

In addition, the 84LM9600 is also equipped with a smart TV function that is equipped with LG's high-end products this year, and uses a motion-sensing somatosensory remote controller to enable easy clicks, gesture operations, voice search, and scroll wheel functions.

4. Resolution Upscaler Plus and 3x XD Engine

The Resolution Upscaler Plus feature enables high-quality rendering of multimedia content on external LG UD 3D TVs, including mobile hard disks, mobile phones, and network resources. This perfectly solves the problem of loss of image quality when viewing external multimedia images on a large screen. Puzzles. This function is mainly used to deal with the status quo of not having enough 4K sources, and the TV and HD video are interpolated and rendered to achieve 4K resolution.

Built-in 3x XD engine, LG original system, voice-activated dynamic remote control and other intelligent control and experience for the product icing on the cake. Users can also enjoy rich 3D resources through VOD on demand, and can also download a variety of applications through the App Store, and can even achieve dual-screen playback or games.

●Design

The TV adopts the same design as the LM8600 series. Its 84-inch large screen is completely developed and produced by LG. It is one of the few 80吋+ panels independently researched and developed in the market. Here we take a look at the appearance of the product.

Its thickness is comparable to that of the frame, and it is not light and thin, but it is not obtrusive with respect to its width of almost two meters.

The base is a common style of LG high-end TVs this year. The appearance of the L-shape makes people feel very safe. In fact, there is a rubber pad on the bottom of the base, and it can't move when placed. This base also supports the lateral rotation of the TV, allowing limited left and right swings to accommodate different viewing directions.

The interface configuration of this Big Mac is very rich, as shown in the above table, in addition, there are other unusual analog signal interfaces.

Similar to LG's previous TV, the physical buttons on the back remain.

2.2 Dolby analog surround system is a major feature of the TV set. It can also provide good speaker effects without external speakers. It is literally explained that 2.2 is a two-channel system and two bass units are configured. From the parameter configuration of the product, the RMS power of the two channels is 10W, and the subwoofer is 15W. The total RMS power of 50W is considered to be very powerful for flat panel TVs with a small internal space.

In 3D, LG has been using polarized 3D technology, so the eye configuration is very simple and lightweight.

●Detailed data quality measurement

First of all, we use the evaluation room professional instrument to carry on the detailed test to the LG 84LM9600, in the test, the television adopts the default parameter, the brightness adjustment is the maximum value. We first record the measured data in the following table.

After the detection of the color analyzer, it can be seen that the LG 84LM9600 reached a color gamut of 77.19% NTSC, which is in the upper middle level of the LCD TV. According to the pixel close-up picture, it can be found that the RGB sub-pixels of the 84LM9600 are similar to those of other IPS TV panels. According to official data, the TV adopts LG's own R&D products and its provider is its brother company LG Display.

The average brightness of the LG 84LM9600 is 285.115cd/m2. This value does not appear to be outstanding, but for a polarized 3D TV, this brightness is sufficient. In addition, taking into account the huge size of the television, to obtain this brightness value is also considered to be performing well.

Because the dynamic contrast ratio marked by the manufacturer generally refers to the ratio of the full white screen to any point of the full black screen, and many TVs adjust the backlight brightness according to the screen content, so the dynamic contrast reference value is relatively low, and ANSI can reflect the television more realistically. Contrast. ANSI contrast refers to dividing the TV picture into 16 blocks of black and white color and testing the center brightness of these blocks separately to obtain more reference picture contrast. The measured value of 473.38:1 is measured here. The machine is medium and high level. Considering its huge size, this value is not bad.

As long as it is a LCD TV, light leakage is inevitable. In order to make it easier for everyone to see the light leakage characteristics, we have done a lighting treatment on the map. The actual situation is not as bad as the picture shows. Due to the use of side-mounted LED backlight design, the light leakage area is also concentrated in the four corners under the completely black screen. From the actual test, the maximum brightness of the different parts is about 30cd/m2.

The LG 84LM9600 uses a triple XD engine. After all, the pixel resolution has been increased by four times. Therefore, the performance of the image processing engine has also been requested. From the actual test screen, the dynamic blur of 100% screenshots is not a fuzzy, unrecognizable paste, but it is a two-frame superimposed type, and the smear is barely noticeable under actual viewing conditions.

The text shows that we intercepted a small part, and the figure below shows a 100% screenshot.

Visible display is indeed LG said, equivalent to four 42-inch Full HD LCD TV's completely seamless connection, if more than 1 meter, the pixel can not be distinguished with the naked eye, and such a large-size TV is really not easy within one meter use.

On the other hand, although there are already many large-size TVs on the market (Sharp's 70-inch or even 80-inch products have been promoted in recent years), the resolution still stays in the high-definition standard, so close-viewing performance is not as good as the 84LM9600. Pixel graininess can be unbearable.

● quality test real shot map

The following also provides some screen shots of the 84LM9600 playing Blu-Ray tester, you can generally have an understanding of its image quality. Including full HD signal, grayscale, color, contrast, black level and color test screen.

It can be seen that the 84LM9600's color reproduction feature is excellent in color accuracy, no overly gorgeous feeling, people feel that the color transition is not natural. Simply from the author's point of view, we do feel that this color style is better, because the color distortion caused by the transition to the pursuit of saturation is not suitable for long-term viewing.

● Super clear video quality (100% screen area proofs)

Here we chose the ultra-clear video screen provided by LG to take a picture pause shot (Canon 40D+17-40 lens). There are night scenes, scenery and other scenes, and it can be seen that the 84LM9600 is natural and full of the reduction of colors, and the accuracy is also quite satisfactory. At the same time, the picture has a high degree of sharpness and the details are rich and clear.

In general, the playback of ultra-clear video reminds us of DTS-HD. The situation is somewhat similar. 4K video provides more details than HD video, and the picture clarity is improved several times. At a distance of one meter, although it cannot A glimpse of the whole leopard, but at this time is also difficult to detect the presence of pixels, rich picture details coupled with the large size of the screen, provided us with a visual feast.

●Smart interface

The LG 84LM9600 continues to use the LG smart platform interface, which is almost the same as the previous models in the menu layout. However, this flagship feature is China's Internet TV feature. With powerful hardware configuration, if it can achieve high-definition network playback, it will be an epoch-making TV program viewing experience.

In addition to intelligent applications, its audio and video adjustment functions are also very powerful. Among them, sound control operations are particularly important. The vocal enhancement function is very useful when watching serials. It can enhance the vocal frequency band by highlighting the midrange and midrange frequencies. Voice playback is clearer.

●LG Apps

The smart features of the LG 84LM9600 are very easy to use. The built-in viewing software is very similar to Google Picasa. It should be the built-in TV version of Picasa.

The current mid-range camera resolution can easily exceed the resolution of a 4k ultra-clear TV, while an oversized display allows more people to view photos at the same time. If you use a smart remote control, it will be easier to operate.

The App Store feels like a supermarket and sees a direct download of choice. Most apps are free.

We tried to open one of the applications and chose to download it automatically after installation. This food app can teach you how to cook, suitable for home-based people to "develop" food at home.

● TV power consumption measured

From the actual test point of view, the average power consumption of the 84LM9600 is about 440w, which is lower than the official rated power of 520w. In addition, after the brightness is reduced, the power consumption is also more obvious. It seems this bright side-mounted LED backlight and The light guide plate system is still a big consumer of electricity, and the power consumption is basically kept above 400W. In terms of power consumption alone, this guy does not save power, but if you think of it as four 42-inch LCD TVs, the power consumption is not high.

● LG 84LM9600 shopping guide analysis and evaluation summary

The product is priced at RMB 17w and you can buy a good mid-size car. Therefore, we think it is not appropriate to purchase such a product at this time. We believe that 60,000 yuan is basically the limit for high-end TVs with brand image. Of course, if "not bad money" is naturally another matter.

At present, the product has been fully distributed in the first-tier and second-tier cities such as Guangzhou Guangshen, which let us marvel at LG's strength, can also arrive at the top products at the same time, and is a product worth 170000 yuan, perhaps LG is optimistic about domestic high-end consumer groups The spending power. In general, with excellent picture quality and large size, this product is placed in the 40-50 flat villa living room will be very faceful of the truth.

Editor's summary: Although the TV display technology has made repeated breakthroughs over the years, it is difficult to make a qualitative leap. Even if it is OLED, compared with the current high-end LCD display panel or plasma panel, it is not completely overwhelming. Therefore, in order to expand the market, major manufacturers put forward concepts such as intelligence, cloud, and network, which are intended to enhance people’s desire to purchase, but with little success. According to the author's opinion, this is because the nature of the industry and the point of appeal of the industry are still the most basic core technology - picture quality. When televisions are finally purchased, the most concern is the quality of the product.

In addition, some consumers think that the current high-definition is not universal, why do we need to be ultra-clear, this just returned to the quality problem we just proposed; with the increase in size, ultra-clear and more and more become an essential skill, because the high-definition in more than 70 After the inch, its image quality began to show more obvious deterioration. If there is no ultra high definition as the support point of the image quality, the image will be appalling when the size is expanded to 80 or more, so it can be said that the large size and ultra-clear image quality will be In the next two years, the development direction of mainstream television technology, what is still lacking is merely a source problem.

Going back to this 84LM9600 TV, we believe that this product can be said to be the “zero machine” of LG Chaoqing TV. It may be the ancestor product of LG and its partners in the ultra-clear era, and the value of 170,000 yuan. It also makes its meaning in the industry more significant than its market significance, because its latecomers may be what we ordinary consumers really need.
