Foreword: This year is a good year for TV. On the one hand, all major brands have waged a price war, television prices have been constantly diving, the lowest price has been frequently refreshed, and crazy has gone into buying, buying, and buying. On the other hand, various techniques to enhance the viewing of films have been introduced into products. 4K, curved surfaces, Quantum dots, OLEDs, HDR, etc. have come. The protagonist to meet with you here is Changhong 55-inch new TV 55G6 . Look at what features it has and what features it does not have.
At a glance, the 55G6 is an all-around TV set with 4K, surface, intelligence, and the most popular HDR. In addition to the above several hot selling points, the TV is also equipped with matrix light control, belonging to the area of ​​the partition backlight, the actual performance behind the detailed narrative.
Understand the product first to understand the brand, when it comes to Changhong, I can clearly recall in my mind the color CRT TV that grew with my childhood. The model is not yet known, but it has a loud series name – Changhong Double Happiness. Let me give you a glimpse of the history of Changhong.
I. About Changhong: Â
Sichuan Changhong, a well-known black-and-white manufacturer in China and even in the world, was born in 1958. At the beginning of its creation, the brand was always a military-grade enterprise producing airborne fire-control radar for the country. Until 1974, Changhong's first black-and-white TV set went into production. Since then, it has taken the first step in its home appliance manufacturing. March 1985 was the most historic moment for Changhong: It marked the mass production of the first domestically produced Changhong color TV sets, and it marked the “TV for young people’s first TV†of our father’s generation.
Since then, Changhong has had a good reputation and led the domestic color TV market for many years. Changhong in the CRT era was crazy, that is, at that time, my family and relatives' homes were continuously replaced by button-based black and white color TVs that could be infrared remote-controlled "big-screen TVs." (In those days, the penetration rate was: The 21-inch is like the 50-inch, the 25-inch is like the 55-inch, the 29-inch is like the 65-inch now.) The fee is lifted to the home with great strength. Its burly body stands on the table quite occupied, but at the moment of boot you will It was shocked by the huge picture and gorgeous colors. The leap of quality of life is self-evident. As a military enterprise product, Changhong TV's natural quality lever, when retired to catch up with the wave of home appliance trade-in, discount 150RMB, Changhong gave me full of memories. Of course, after the Changhong also took a lot of detours, I remember that year Changhong also spent a great deal of effort to join the plasma production, when Panasonic plasma disappeared, but also occasionally saw the Changhong plasma figure.
On the other hand, under the trend of product diversification, Changhong has also been working on white chess and whiteware. Finally in November 2005, Sichuan Changhong was willing to become the “new owner†of Meiling Electric. In December 2007, Sichuan Changhong became a major shareholder of Huayi Compressor. At this point, Changhong has completed the overall layout of its own black and white household appliances. It owns four listed companies: Sichuan Changhong, Meiling Electric Appliances, Huayi Compressor and Changhong Jiahua.
Having said so much, the purpose is to let the officers see Changhong have a certain brand awareness, may be able to generate some resonance, after all, is full of memories. Luo Yulong said: Feelings need training. The following began to evaluate today's protagonist - Changhong curved TV 55G6.
Second, transport and unpacking
Shunfeng, which is made by logistics, is naturally reassuring for packaging protection. I do not know why the residential property did not let SF brother to drive in, poor brother can only be brought in with a trailer, the day was also a little light rain, there is still water on the road, such a big guy hard brother.
SF brother is still very face to face, put a poss.
The box is covered with a thick layer of honeycomb shock-absorbing paper on the screen to prevent the screen from being damaged during transportation.
The other side is the packaging as a whole, the product is defined as "U-MAX living room TV", the specific features and other details after opening the box.
It is worth buying a sticker. This time, there is no such thing as 'the value is worth it'.
On the side, there are transportation issues to remind you to protect your transportation.
The factory labeling, indicating the product's color, package weight, TV size and production date, the production date is March 29, freshly baked.
Press the buckle inwards and lift the box to remove the TV.
The curved screen is protected by a loss-preventing film that prevents the machine from shaking and provides a cushioning effect to the screen.
Changhong 55G6 uses a pair of dovetail bases. It has a simple structure and is easy to install. It can be easily assembled by simply mounting four screws. The installation process will not be described here.
Third, the appearance of the show
1 TV frame:
Changhong 55G6 TV adopts a very narrow frame design, which can give people a visual impact of super-high screen ratio when displaying pictures. After measuring the border, left and right width of 8 mm, using black high-light processing, the lower frame is 11.5 mm, the use of champagne metal wire drawing process, the bottom of the middle of the metal mosaic Changhong LOGO " Changhong ", with the power indicator light below, The overall design of the border is elegant and exquisite, with a sense of fashion.
Unfortunately, there is still a gap between the TV frame and the screen. Fortunately, there is no gap leakage like some domestic TVs. It is only necessary to pay attention to the position of the gaps in the television.
After measuring the screen and the border there is a 3 mm black border, but fortunately the TV itself is not wide, the black border plus the border width is only 11 mm wide, and usually watching the black side is negligible.
2 TV thickness:
As early as before receiving the goods, I had taken care of the pills. The machine would surely be thicker. After all, it was a curved surface television and it was a direct-lit backlight. I did not expect that the moment of seeing the real machine was really shocked and unexpected. A lot of thin, the actual measurement of the thickness of the top of the TV is 14 mm, the maximum thickness of the bottom is 58 mm, here to Changhong point like.
3 Surface screen:
Looking down you can see that this TV is different from a normal flat-screen TV. 
This angle can clearly see the curvature of the surface of the curved TV, it can be said to be like a full moon. Ergonomically, absorb instantly and prevent side leakage. I seem to say something wrong.
Changhong 55G6 uses a curvature screen of 4000R. It is said that the screen can be parallel with the eyeball when viewed, and it is in line with the natural formation of human vision and vision, providing more comfortable and more realistic viewing effects, and stronger presence on the spot, immersing the audience in the picture. Bring a stunning wrap-around movie experience. The actual experience will be described in detail below. Answer two questions first:
1) Why 4000R: It is generally believed that the curvature of the curved screen is better than 3000R. The smaller the bending rate number, the greater the bending, and the bending rate is too uncomfortable for the human eye, while the 4000R is considered as the golden curvature. Not because of the effect of TV itself, but the curvature of 4000R is closest to the curvature of the human eye, which is the so-called fit.
2) The surface is not necessary: ​​this problem is a bit metaphysical, some people think that the surface TV is a retrogression in the development of television, flat-panel TVs should be a tablet. How many years ago, people tried their best to make TV ultra-thin, from spherical CRT to flat CRT, flat CRT to rear projection TV, rear projection and plasma to the current LCD. "Thinner than thinner" has been refreshed the thinnest record countless times, and the advent of curved TV breaks this tradition. Straight down backlighting and curved surfaces are certainly unacceptable for pursuing ultimate appearance control. However, curved televisions The improvement of the user's vision, even if it is a small improvement, is the meaning of its existence.
Can you judge a symmetric mouse and an ergonomic mouse? Can you determine that with the ergonomic chair, should the traditional wooden chair be firewood? In fact, it is not the purpose of judging whether this is good or bad.
4 metal base
If a TV mount is for the overall beauty of a complete home improvement, then the seat is absolutely enjoy the design of the TV itself. Changhong 55G6 has two pairs of dovetail aluminum alloy base, which belongs to the popular double point support. The same champagne gold color echoes the bottom frame. The distance between the two bases is slightly wider than the width of the TV set, and the spacing is 123 cm. (There is a wooden feeling that this base design is very selective to the TV cabinet. The one-side cabinet or the countertop TV cabinet can only be mounted.) .
5 TV back
On the back, a black-all-in-one shell is used, with a slightly raised texture, and the texture is very good. This rear shell is different from the ordinary spliced ​​rear shell, the one-piece molding is more robust and durable, the overall sense is stronger, the nameplate and various interfaces are all placed on the lower part of the fuselage.
The even distribution of the two rows of cooling holes provides a highly efficient cooling while also providing a beautiful appearance at the back of the TV.
The nameplate shows the product model, energy consumption and safety tips.
There are four mounting holes on the back and the attached accessories must be installed before mounting.
6. Buttons and interfaces
The button design uses an innovative operating lever instead of a traditional row of buttons. Short press to do the power button, long press will call out the multi-energy button operation interface. Â
Due to the blind operation on the back of the machine, you just need to familiarize yourself with this multi-function key. Personally feel that this key design is not as convenient as a power switch.
The location of the USB interface is very user-friendly, close to the 10.7 centimeter position on the left edge of the fuselage, which is conducive to the usual blind operation. After all, the USB is one of the interfaces that are usually plugged in and out, and it is easy to mount the storage device regardless of the wall mount or wall mount. Access. It is a pity that the two USB interfaces are both 2.0, and they are not equipped with a USB 3.0 interface. The speed of decoding videos via USB is still affected.
In turn, there are commonly used interfaces such as digital audio output interfaces, network interfaces, HDMI interfaces, AV segments, and antennas. This TV has 3 sets of HDMI2.0 interfaces. The player's own play machine guide has detailed interface instructions.
7 TV remote control
Shape design: The remote control is small and sleek. The overall design is streamlined and the back is raised. It is very comfortable to hold in hand. However, the quality is light, the material is general, and the texture is not good.
Button layout: relatively simple, positive in addition to a few conventional operation buttons, there are also dedicated UMAX viewing and Penguin VIP these two shortcut keys. Because it is the main smart function of the TV, and does not have a common number buttons, more like a TV box remote control. Need to Tucao is due to the Penguin VIP shortcut keys placed in the most convenient place to operate the thumb, it is easy to confuse it with the return key before the habit, there is an error operation, and points must enter the VIP page must wait to exit This is not enough humanization.
Control experience: remote control does not have voice operation and somatosensory operation, somewhat regrettable. The use of two 7-cell batteries, although infrared remote control but the control range is still relatively free.
8 Other accessories
Manual, warranty card, power cord, hanging accessories.
Fourth, screen evaluation
This link is still tested by Nokia Monitor Test and DisplayX, 4K static performance using USB to play 4K test chart.
1 Grayscale performance
It can be seen that the gray-scale performance shows a clear hierarchy with light and shade transitioning naturally. Just playing a BUG with the USB play test graph, resulting in grayscale display is not allowed, this bug later said.
2 color reproduction
The default factory settings of the machine are white and bright, and the brightness and contrast are turned down. There is still a common problem with TVs. There are slight dark corners on the four corners of the screen. With the four corners of the curved TV being closer to the human eye, the camera will be more vignetting.
BUG mentioned above when testing grayscale: When you use the USB port to read the picture, no matter what the picture will show normal color automatically becomes HDR optimized picture after a few seconds, the color will change, even if you put the dynamic drop Both noise and dynamic depth of field are useless, which means that you basically read photos from a USB flash drive.
It can be seen that the left side is the true color and the right side is the HDR-optimized color, and there is a significant color difference.
3 4K definition
With the super macro close-up tick marks (the higher the number is, the clearer), the high energy reaches 25, and the limit 28 appears blurred. Here you can also see that the machine is using a real 3 color 4K screen, and each pixel is arranged vertically by the blue, green and red primary colors.
The limit of test text performance, ABCDEF pointed by the red arrow is still clearly visible.
Chinese characters are more difficult to perform, and the smallest font is still clear to see the outline of the text. The performance of this 4k screen has been quite good.
4 viewing angle
No color shift was observed in the shooting up and down, and the viewing angle did not affect much. People sitting on the edge of the sofa no longer had to worry about seeing whitish images.
5 dynamic analysis
6 HDR Blessing
What is HDR:
HDR will make the picture look very realistic, and the gray level and details are almost the reduction of real life. It can simulate light reflections, making light and dark look natural. What is important is that in both cases, it still shows exquisite details and subtle hues. HDR super quality display technology can greatly enhance the picture details and layering, make the bright part of the film more clear, the depth of the part more depth, looks structured, creating a more natural look closer to the reality.
The picture on the top of each picture is the standard picture quality output by the computer. The figure below shows the effect optimized by the HDR algorithm.
V. Intelligent Hardware and System UI
55G6's smart hardware uses ARM's 64-bit A53 dual-core CPU, equipped with the MAli-T720GPU, and with its 1GB of DDR3 memory is obviously a bit shabby. In the era when the new smart TV memory is generally approaching 3 GB, Changhong has some lack of sincerity. CPU and GPU performance can be used. However, this running memory is flawed. The smart system will surely have a Caton phenomenon after running for a long time. Clean up the background often, or change to a better box.
Pressing the home button on the remote control will take you to the UI homepage, followed by select, on-demand, music, shopping, education, games, apps, my related and system settings. The bottom row is the first level menu, and the top application is the second level menu. The operation logic is for the first time from the first level menu (select) to the second level menu and jumps to the first application in the second level menu (My Tracks), and then the operation is selected by pressing the normal direction keys. Unclear, I hope that the upgrade will change this logic in the future.
My homepage is filled with information such as message alerts, personal achievements, etc. Changhong named the system “Rainbow Scarfâ€, a system that can make money, according to the instructions to do the task, you can get popularity, save gold coins, and redeem some paid programs. Or a lucky draw.
The system settings menu is a number of utility tools, including reading a variety of documents, system weight, multi-screen interaction.
It is worth mentioning that the multi-screen interactive mobile phone remote control is very practical. It instantly turns the mobile phone into a remote control, which makes up for the lack of voice and somatosensory regrets in the machine's own remote control. It is also much more convenient to play the game.
Sixth, online resources
Gold coins for tasks can be exchanged for different gifts at the Treasure House.
TV dramas, movies, and variety shows are mostly from ICNTV. Penguin TV is rich in content, but you want to charge for the program. If you want to do it for free, you can download it from the A and B stations.
This learning channel is not bad. I can learn English and listen to stories when my child is a little older, saving me from telling stories personally.
Music menu, in addition to QQ music other software must be installed to play, usually just enough to use QQ music.
Seven, UMAX experience and put the effect
The first half of the video is the standard mode of viewing. After the second half of the video is turned on, the UMAX is turned on. The picture is more natural. The sound changes from a flat and unobtrusive effect to surround sound. Its volume increases several times, and it feels like a movie theater. I recommend watching TV. Live broadcast using standard mode, TV shows and movies is strongly recommended to open the UMAX mode, watching the Champions League rely on it.
Open UMAX mode, playing music effects lever, I like this feeling.
VIII. Summary of recommendations
Advantages: 1 The machine is stylish and beautiful, with only narrow borders and strong visual impact.
2 Surface, 4K, HDR. The dynamic depth of field, these popular elements should be available, and resource conditions can indeed bring about a qualitative leap.
3 UMAX mode can bring a small theater-like enjoyment.
4 The smart system has no obvious shortcomings. You can enjoy free viewing of paid resources when you perform tasks.
5 Online resources are rich and playable.
Disadvantages:
1 USB will appear color cast when viewing pictures.
2 The texture of the remote control is poor, and the layout of the buttons is unreasonable.
3 The default mode screen is white and needs manual adjustment.
4 USB playback 4K video compatibility issues, many 4K videos can not be played.
5 The fuselage runs a short board of memory, which may cause a jam in the application.
Nine, all kinds of screen camera
