Skyworth TV G7200 evaluation, Xiao Bian provides users with the advantages of Skyworth TV G7200 features a comprehensive analysis of introduction, to help everyone better understand this smart TV. Skyworth TV G7200 is a new product line affiliated to Skyworth's geek Internet TV series, jointly launched by LG Display, Huawei Hass and other manufacturers. It was initially established as the highest-end product line. The Skyworth GLED Air G7200, launched on April 5th, is the latest in the series.
Skyworth TV G7200 is Skyworth's main push smart TV product in 2015, providing users with ultra-thin design of 4-color 4K, 3-layer integrated module, domestic first 64-bit chip, H.265 hard solution, and Geek Box/Geek Max "Geek Pod is the core 64-bit TV system" and many other selling points.
Exterior
The G7200's biggest feature is the borderless design. The front is almost black, with a moon arc base underneath, and a slim metal edging can be seen on the side.
Thanks to the three-layer integrated module technology that combines the backlight with the LCD glass, the thickness of the body is reduced to 7.9mm. For the first time, the thickness of 7.9mm appears on the TV. This is really shocking. The effect can make up for the iPad's 55-inch but constant thickness effect.
The white back cover is made of metal material. The steel back board has ribs to strengthen the body's rigidity. The built-in Geek Sound Blaster is underneath, and the TV also supports external Geek Bass sound system.
The right side of the fuselage has all the interfaces. In addition to the regular interface, the machine also provides HDMI2.0 and USB3.0 interfaces.
The G7200's remote control has a special shape. The ergonomically designed housing is somewhat similar to eggplant. Compared to traditional TVs, the number of keys has been greatly simplified. Optional accessories include a 3D body detection camera and a game gun.
Open the protective cover on the back of the fuselage, you can see the circuit board of the machine, the wiring is more neat, put a large piece of heat sink on the CPU, the material is quite kind.
The back cover of the screen has the factory information of the screen, and the original LG screen made in Korea has its label and machine code on it.
Display quality
On the picture quality, the parameters given by the manufacturers are quite gorgeous: LG Display's original 4-color (white, red, green, and blue) 4K Air screen panels use a cadmium-free color gamut technology, and also add D to the backlight diaphragm. -BEF double brightness enhancement film, after the crazy stuffing with technology, the actual performance of the machine will be?
According to the lab pixel enlargement, each pixel of the LG Display panel is actually composed of four pixels: white, red, green, and blue, which adds more white pixels than conventional red, green, and blue color panels. Can significantly enhance the highlights of the screen, and in order to enhance the contrast of the panel. The function of the D-BEF brightness enhancement film is to collect light, which is also used to increase brightness.
According to the ultra-high definition display authentication technical specification promulgated by CESI (China Electronics Standardization Institute) in 2014, one by one, the parameters of the machine such as "clearness, reappearance, horizontal viewing angle, contrast" were tested one by one in the laboratory.
The maximum display values ​​of the machine's sharpness and reappearance rate are 2160 and 100, and the horizontal viewing angle reaches 178 degrees. This figure has approached the limit of the test equipment, while the horizontal brightness angle of view is 96 degrees, and the performance is quite excellent;
The contrast ratio (brightness difference between the brightest white and the darkest black in the light and dark areas of the image) is 341.1:1, which is in contrast to the 120:1 standard of ordinary television and the 200:1 requirement of the 4K television background. A lot higher.
In the laboratory, the machine's panel performance is quite good, although the parameters are not necessarily representative of the actual perception is good, but the parameters are certainly an important basis for the actual perception.
The actual perception, the machine's color performance is more colorful, and thanks to the 4K panel, the machine's screen resolution is more fierce. When playing 4K video, if you are watching at a closer distance, you can see a lot of details that cannot be seen on the small screen.
The additional white pixels of the 4-color screen greatly increase the maximum brightness of the screen. In the light and shade contrast scene, the details of the highlight are quite abundant. The D-BEF brightness enhancement film concentrates the scattered light and acts as a condenser to increase the light utilization efficiency, thereby increasing the brightness and making the dark details clearer. Although the chance of watching TV in the black field is small, As a price, the white pixels added by the machine cause the brightness of the machine to be very high, and it will look brighter when viewed in a darker scene.
Sound quality
The Skyworth G7200's built-in stereo is known as the Geek Sound Blaster, which supports dual decoding of DTS and DOLBY, while the Geek Bass passive subwoofer is an optional accessory. The test uses the built-in Geek Sound Blaster.
The test environment is the national anechoic room of the National Digital Audio & Video and Multimedia Product Quality Supervision and Inspection Center. The measuring microphone is located 2m in front of the TV. The professional audio signal generator sends the signal to the television to sound, and then the microphone collects the actual sound information. Finally, the audio analyzer compares the original signal with the actual sound.
The acoustic frequency response range of the machine, the measured results are respectively left channel 85Hz ~ 20kHz, right channel 91Hz ~ 20kHz. The high-frequency part of the machine performs quite well and has reached the human ear limit (20 kHz). The overall value exceeds the 90Hz~15kHz of the vast majority of 4K TVs and far exceeds the 160~6.3kHz specified by the general specification of digital TV liquid crystal displays.
Total harmonic distortion (the smaller the value, the clearer the tone, less than 1% of the human ears can not distinguish), the left channel is 6%, the right channel is 5%, also far below the LCD specification 10%. The actual sense of hearing, the machine's sound quality is relatively pure, wide range, low noise floor, a good degree of reduction, and the volume is higher, turning over a few hundred pieces of PC sound problems.
performance
The CPU model of the machine is Hi3751V600. It is a 64-bit SoC independently developed by Huawei Hass. It uses a 64-bit 4-core A53 architecture and is clocked at 1.5GHz. The GPU is a 6-core Mali 450 with 16GB EMMC flash memory. In addition, it also incorporates two Hi-Vengine VPUs for hard decoding in the H.265 format, which can increase the smoothness of playback of network video files and reduce power consumption.
The security Bunny of the machine is divided into about 22000 points, and the performance and performance surpass the current mainstream 4-core A7/dual-core A9 processor.
In terms of actual performance, the boot time of the machine is about 18 seconds, and the response time of the built-in application is fast. On the real-time search that requires high CPU computing power, the response time does not exceed 1S, and the performance is good.
System and Application
Skyworth specifically introduced its own operating system for smart TVs. In order to maximize the performance of the new 64-bit CPUs, the system became the first 64-bit TV system to be backward compatible with 32-bit Android applications.
In addition to 64-bit support, the system's biggest feature is the application platform with Geek Box, Geek Max, and Geek Pod as the core applications. In addition, Skyworth's own application market "Cool Application Circle".
Geek Box
Geek Box is Skyworth's video game platform, which includes Geek Hero, Geek Quick, and Geek Quick Match. The control method in the game is based on the virtual remote control of the mobile phone. It is necessary to download the official mobile phone virtual remote control app "chicken virtual controller". In addition, the official also provided additional machine gun handles.
In the course of the game, the cursor/precision head will follow the pointing movement of the game gun, real-time tracking is quite sensitive, there is a kind of infrared real-time aiming at the enemy, when playing gun shooting game is simply the existence of cheating.
Geek’s fast hands are the TV, handheld and arcade game markets. They include PSP, PS, N64, DC, MAME, FBA, FC, SFC, MD, and many other platforms for porting games, such as King of Fighters, alloy warheads, and robot battles. The classic masterpieces are all in it.
Many of the games support doubles and multiplayer games. You can use Bluetooth or USB handles to connect to your TV. If you have more casual friends, you can even use your phone as a controller to play multiplayer games.
Geek Max
It is a viewing channel, using the iQIYI video source, there are H.265 area, 4K very clear channel, Dolby three areas.
As the name suggests, the three zones are the H.265 standard-encoded video, 4K video, and the viewing channel that provides Dolby audio, corresponding to the user's needs for network speed, clarity, and sound effects. The source update rate is not bad. Dear, one-man martial arts and other newly-painted movies have already provided HD versions.
Geek Pod
Geek Pod can be said to be the G7200's K song platform, which contains MV resources including 4K super clear, MV, concerts, special topics, KTV several sections.
The main push of this platform is the massive amount of genuine music copyright, including tens of thousands of KTV popular genuine songs and popular music videos including family karaoke, the latest MV premiere, and live concerts. This is obviously for users who have a demand for K songs. Even if they don’t update after bringing their own microphones, these MVs are enough to sing for several years...
It is Skyworth's own TV application market. The market is categorized according to games, learning and education, and shopping. What is more special is learning education and shopping software. Among them, Suning's TV series and sofa purchases are relatively rare in TV applications. The experience is also quite good. It is considered an official pit in the TV shopping field.
TV school
In addition to physical remote control, many TV manufacturers will provide mobile phone remote control app, and Skyworth will provide a mobile phone remote control app named "TV pie."
In addition to the conventional remote control key mapping, the built-in 7-screen video platform has an exclusive on-demand function that can be pushed to the TV with a push of a button in the mobile phone. In this way, the search that the TV is not very good at can be transferred to the mobile phone, and it is relatively easy to use. .
What is even rarer is that TV has its own WeChat public number. After attention, it can still be used as a remote control. At the same time, photos, music, and other content can be directly pushed to the TV screen. The delay is short and the experience is not bad.
to sum up
Reviewing the new technology selling point of the G7200, the 7.9mm thickness of the three-layer integrated module, and the 4-color 4K screen with the D-BEF double brightness enhancement film, both in terms of brightness, contrast, sharpness, and viewing angle There is a very good performance; and China's first 64-bit TV chip with Skyworth's own 64-bit TV system, also brought a good H.265 hard solution and daily performance.
Of course, in addition to the high-end configuration and performance, the G7200 is also relatively high-priced. It is divided into 49-inch and 55-inch versions, priced at 5999 yuan and 8599 yuan. The G7200 is considered an attempt by domestic manufacturers to attack the high-end television industry. However, this time the route is still similar to the "cost-effectiveness" route: Although the price of the G7200 has been close to that of foreign brands with the same size products, the configuration is still a lot higher. The good news is that this time the price/performance improvement is based on improving performance rather than lowering prices.
