In the area of ​​home appliances, LG is a brand with a relatively wide coverage. Air-conditioners from refrigerators and televisions can almost cover all home appliances. Among them, TV is a feature of LG. After all, in the field of panels, LG is the world's largest LCD. Panel makers, whose products are not only for their own use, but also suppliers such as Apple's Lenovo and other large companies, so this time I still chose LG's TV products for TV purchases.
About 60LG61CH-CD
LG e-color 60-inch IPS hard screen 4K HDR ultra-high-definition smart LCD TV (60LG61CH-CD) 5699 yuan This LG TV still uses its own hard-screen LCD panel with a resolution of 4K. Direct type backlight. Equipped with HDR technology, it provides a brighter picture with clear contrast between light and shade. Built-in webOS operating system, simple and quick operation. The 20W power stereo supports surround sound and brings a nice viewing experience. Supports H.265 decoding technology. The appearance size is 1348*839*263mm. Jingdong direct link to encyclopedia This 60LG61CH-CD is a new TV introduced this year by LG, using IPS hard screen panels, 4K resolution, and support for HDR technology, from the panel data point of view, this TV brings the actual results should be amazing.
What is HDR TV?HDR TV uses HDR technology to synthesize the final HDR image according to the best detail LDR image for each exposure time, which can better reflect the visual effect in the real environment. The HDR is a High-Dynamic Range (HDR) image, which can provide more dynamic range and image details than an ordinary image. The LDR (Low-Dynamic Range) image according to the different exposure time Using the LDR image corresponding to the best detail for each exposure time to compose the final HDR image[1], it can better reflect the visual effect in the real environment.
The use of HDR is mainly reflected in the way it changes the picture. Under the influence of HDR, the colors presented by the TV are more vivid, the black is deeper, and the objects on the screen are clearer. At the same time, the hue of the picture is also enlarged, alternating between cool and warm colors.
package
How big is 60 inches? Diagonal 151 cm, if you remember the Pythagorean theorem should be able to clearly calculate the side length, plus the thickness of the box, this is a box one meter high, one meter long, but fortunately the LCD panel to make the TV more Lighter and thinner, otherwise such a large-size TV is a particularly troublesome thing to carry.
This TV is a new 2016 product. The manufacturer is LG Electronics's production company, Lejin Electronics, with an energy efficiency rating of Class 1, which is a green, low-energy, environmentally friendly product.
Appearance and details
The first one is a comparison chart. Behind it is a 120-inch screen. In front of it is a 60-inch TV. It can be clearly seen that the area of ​​this TV is one quarter of the screen. 
This is the distribution of the TV stand, herringbone design, plastic material, double screw fixation, because now the family to buy a TV is basically a wall-mounted installation, the bracket is basically an extra product, so this TV bracket design is not used very Special place. Practicalism.
The included remote control is a standard product. It should be the remote control used by the entire LG TV equipped with a web system (which is the same as the remote control I had previously tested). With 44 keys, it seems that the buttons are very complicated. But in fact it is not complicated, the whole is divided into four areas, the control area, the digital area, the adjustment area, the multi-purpose area, respectively, to assume different functions to use, familiar soon after getting started.
interface
On the port, equipped with three HDMI interfaces, two of which are HDMI version 1.4, one on the side and one on the back, one HDMI 2.0 port on the back, equipped with HEVC decoding technology. HDMI 1.4 can already support 4K, but subject to bandwidth, the highest can only reach 3840 × 2160 resolution and 30FPS frame rate, HDMI 2.0 will expand the bandwidth to 18Gbps, can support 3840 × 2160 resolution and 50FPS, 60FPS frame rate. At the same time support up to 32 channels in audio, and the highest sampling rate of 1536kHz. Therefore, when we add an external 4k box, we can choose which HDMI interface to insert according to the frame rate supported by the box. At the same time, the standard optical audio output interface supports DTS and Dolby audio decoding, which also creates the conditions for the home theater link. In addition, the standard dual-band wireless network card is added to the wired network port. One usb interface, from the color point of view belongs to usb2.0 version, support u disk insert play video.
About HEVC decoding
Video compression is already one of the essential home entertainments in our lives. Without it, we will live in a world where there are only a few dozen TV channels, and it is simply unthinkable at the moment. . Digital technology first appeared in the United Kingdom. At that time, people already had televisions. Through the continuous evolution of digital technology, terrestrial television channels rapidly developed from 5 to more than 30, which greatly enriched people's daily life and entertainment. The original television content that people can watch is not much. However, the existing compression solutions, such as H.264, MPEG-4, etc., are still very backward technology. Maybe you will say that various video content like Apple iTunes downloads. Both H.264 and H.264 are used in the H.264 HDTV channel codec, but today we are introducing more efficient video coding (HEVC, H.265) but it is still an indisputable fact. The HEVC compression scheme can increase the compression efficiency of 1080P video content by about 50%, which means that the quality of the video content will increase much, and it can save a lot of network bandwidth. For consumers, we can enjoy higher Quality 4K video, 3D Blu-ray, HDTV content.
HEVC can be considered an upcoming protocol standard soon, because whether it is a 3D Blu-ray player or some other streaming media player, it urgently needs a new codec to achieve the ability to play 4K content. It is very gratifying that the entire framework of the HEVC protocol standard has been defined, and it will more than double the compression efficiency based on the 2 to 4 times the complexity of the H.264 standard.
Of course, the new codecs also have the inevitable drawback that they do not support most hardware and usually require more efficiency and more processors to assist, which means that if there is a firmware that needs to be updated, the codec If you can't keep up with the upgrade speed, then our TV set-top box and Blu-ray player cannot play HEVC-encoded content. We need to wait for the solution to appear before we can continue to use it.
Even so, many well-known TV brands and media operators in the world still regard the HEVC protocol standard as the main research and development media format in the future. For example, Panasonic has made it clear that it will use the protocol in its future 4K TV and OLED TV. It is believed that in the near future, the HEVC protocol standard will be performed with strong compression efficiency, and the video compression technology will be pushed to a new height, becoming the benchmark for television and radio carriers.
The power button on the bottom of the TV adopts the design of a five-dimensional navigation bar. In addition to the on/off switch, it also has the functions of up and down and left and right menu selection. Currently, it is the standard configuration of LG TV.
The TV nameplate, including the manufacturer and the time of manufacture, is an important warranty for today when we are not good at keeping the warranty card.
In today's popularity of smart TVs, LG naturally can not lag behind, and now the TVs are equipped with a smart operating system, but unlike other manufacturers generally carry Android systems, LG is definitely a literary youth in the TV industry, not to take the unusual road Fresh style, equipped with webos system, has been updated to version 3.0.
WebOs
Palm webOS is an embedded operating system, with the Linux kernel as the main body and some proprietary software developed by Palm. It is primarily developed for Palm smartphones. The platform was announced to the public at the Las Vegas International Consumer Electronics Show on January 8, 2009 and was released on June 6, 2009. The platform is the de facto PalmOS successor, and webOS focuses on the integration of online social networking and Web 2.0. The first smart phone equipped with a webOS system was the Palm Pre, which was released on June 6, 2009. As Palm was acquired by HP, webOS was taken over by HP. On the early morning of August 19, 2011, at the third quarter financial report meeting of Hewlett-Packard, Hewlett-Packard announced to abandon all operations around TouchPad tablet computer and webOS mobile phone formally. LG acquired the entire assets of WebOS from HP HP, including source code, employees, and related patents. Since then LG has been relatively low-key. However, at the International Consumer Electronics Show in Las Vegas, webOS relaunched. In LG's webOS smart TV, a webOS classic card-like interface was adopted, and some commonly used mobile clients such as Facebook and Twitter were simultaneously launched. , YouTube, and mobile browsers. In addition, users can quickly switch between multiple applications. According to media commentary, in the era of Palm and HP, webOS completely failed in the consumer electronics market. From the perspective of LG's exhibiting pictures, LG is ready to let webOS become the protagonist of the exhibition and let it embark on the journey again.
Probably people of my age had quite a few experiences with using palm phones. Perhaps everyone was impressed by the smooth running of the web system on mobile phones and the basic requirements that are not harsh on the hardware. It makes people miss the memory and the fluency of the web system. Compared to today's hot Android system and ios is not inferior, but unfortunately HP's lack of development support for the year, eventually lost the market in the mobile operating system competition, and ultimately sold the entire system to LG, LG will web system from the phone Fully transferred to television, it is intended to create a smooth TV operating system, and has persisted so far.
Prepare before use
System boot screen, feels a little simple and slightly artistic animation
The basic steps after booting, choose the language, region, use environment and connection network, the choice of the environment has a family outdoor and other choices, the main purpose is to automatically adjust the brightness and contrast to adapt to different environments.
LG's keyboard design puts letters and numbers together and is relatively easy to input.

From the terms, the source of personalized advertising information is mainly through viewing. Information and search keywords come from targeted delivery ads. Advertising cannot be eliminated.
At this step, basically the tedious setup is completed. This setup step requires clicking the OK button of the remote controller for more than ten times, but fortunately, the above settings are only set once when the device is turned on for the first time. .
OS
The webos system interface adopts a card-based design. The menu is selected from left to right. The operation is smooth and smooth. There is no stabling, and the built-in content partner is China TV. As a Chinese-licensed content provider, China has one of the few official backgrounds.
Applications in the app store include entertainment, lifestyle, games, education, news, and information. Currently, all of them are free, including games, and the largest number are also games, but the overall number of applications is not much, less than one hundred. In terms of application development, LG also needs to provide more support and encouragement for application developers.
Similarly, on content provision, only TV dramas and some entertainment programs are free, if you need to watch movies, you need to buy enough members, you need more than 200 a year, the price is indeed not cheap, but new users can enjoy a 10-day VIP experience If you find a movie you like, you can sign up for a new user to enjoy the visual experience of the 60-inch big screen.
Of course, if you do not have a monthly package for a quarterly package year, you can support a single point, a film of 5 yuan, the highest definition is FHD, and the same price as other video sites.
Visual effect
This is the built-in TV series TV play effect, China's video resolution resolution is still relatively high, reached 1080P, but this is Taiwan 4k TV, of course, can not simply play 1080p video, so I got two Segment 4K video is played over USB and tested for effects.
In the photo and video options, you can find the usb plug-in device, click to enter to view the U disk file
U disk playback 4K video smooth, you can see this TV's hardware decoding capability is very strong, have to say that 4k screen is indeed true and delicate, visually stunning.
You may not be able to see clearly on the pictures you have taken. Then I took a screenshot and zoomed in to see if it was really visible and clear (I said it was eyelashes).
Pixel zoom in, you can see how pixels are arranged.
Special feature
Multi-screen interaction is a standard feature of LG. We can directly project TVs or computers and flat-panels on TVs with TVs in the same wifi network. In this way, watching videos and playing games will no longer cause the screen to be too small.
Android phones can be found in the settings of the wireless display options, open the device to find the click connection.
Then my phone screen is instantly displayed on the TV. Then we can operate on the phone, such as playing photos, watching videos, etc. There is no sense of delay in the operation, the picture is completely synchronized.
Two pauls on December 17th, Chengdu, Chengdu, China.
Video function, for some live events, we may miss due to work reasons, this time the video function is very good to fill this regret, as long as the U disk in the USB interface, click on the recording or appointment recording, we will be due to other The wonderful TV programs missed by triviality are recorded and watched when convenient.
Smart TV band games are not particularly new, so I also tried to play a 3D car game, because the application on the webos system is slightly less than these small games is not a big investment in production, basically using the remote control The arrow keys on the operation, belonging to the leisure class, not a competitive item game, occasionally play is good.
to sum upThe 4K IPS hard screen mounted on the LG 60LG61CH-CD lock is the main factor in my selection of this TV. The color gamut and the angle are all in the excellent class. It is controlled by the price, and no frequency multiplier technology is used, but the HDR joins this deficiency. The make-up at the place, the visual effects will not be much affected, especially the HDMI2.0 interface to join, you can play 60 frames of 4K video, smear phenomenon is basically not, equipped with the webos system operation is very smooth, And the interface is simple and easy to use, suitable for the elderly at home, although the current application is slightly insufficient, but as the main system of LG TV, hope that the official can put more effort in application development, 4999 price in the 60-inch overseas brand television It also belongs to a very cost-effective price.
