Saying that the day is on the way to work, the mobile phone text messages jumped out of a message, Aunt Zhang Tips: You have successfully applied for a comprehensive test product Changhong 55G6 4K curved TV love Zhang Aunt, not only gave us a lot of duo wool (shou) the opportunity , I was fortunate enough to burst into the LCD TV of Changhong. Thank you for choosing my Xiaobian. If you are flattering, you don’t have much to say about it. Let’s talk about the maker of this product, Changhong. Changhong is a veteran electrical appliance manufacturer in China. It was founded in 1958. It has a deep skill in the field of televisions, especially in the plasma field. It was also the domestic image quality NO.1. So far many home appliance forums still miss its classic flagship 50900 and 58938, but unfortunately with the plasma suddenly delisting, Changhong plasma's glory has long ceased to exist. At present, Changhong TV is smart with Internet intelligence, light and thin as its selling point, and is fighting against the market through Changhong and CHiQ's dual-brand strategy. It also has a large share in the fierce LCD market. The 55G6 official price of the evaluation of 4599 (the actual transaction price of 3999), should be Changhong to create a low-end series of curved screen (the flagship is 55G9 oled, the price of 12999). Judging from the selling price of Jingdong's curved surface TV, even in the domestic brands, the price of 55G6 is still relatively low. This point is that Changhong is still very pragmatic. As for whether it is cheap or not, it depends on the evaluation behind it. First, open the box installation Worth buying is to arrange SF to send to the home, but unfortunately when I delivered SF, I was just outside to stay with the baby and the family did not ask for an inspection. Level 3 energy efficiency, although not in line with the trend, but I always insist on tangling the power of the TV does not make sense. Because the goods are not opened during the inspection, although Shunfeng courier said that if he had a problem with the box directly to find him, the problem is that if the broken screen is still unclear, so I dare not open the box, honestly spend money Find Changhong out of the box to install the base bar Changhong LCD installation charges map, spent 50 oceans. Open up! Oh no, it's right out of the box. A look to know that the curved TV ^ _ ^ Changhong is now very fond of local tyrants' golden bases. The material of the pedestal should be metal, relatively thick, and stability is certainly not a problem, but the biggest problem with such pedestals is that they cannot rotate the screen. From a practical point of view, I still like the base of the previous sony LCD that can be rotated. The installation is complete. Here, I remind you that although I have always said that this 50 yuan is not worth the flower, and this machine is not very heavy (15 kg), but because of the large size of the 55-inch curved screen, a person is still very difficult to handle, easy to fall and cause damage Or personal injury, so if there is only one strong labor force at home, it is strongly recommended to spend money called Changhong installation. Second, appearance and accessories Well, the following finally to the boot evaluation, in fact, I am also very tangled, out of the box accessories do not write it, always feel incomplete, write it afraid that everyone feels boring, dilemma ah Third, the system experience Let's first look at the 55G6 parameters in the system: CortexA53 dual-core CPU + Mali-T7204 nuclear GPU + 1GB DDR3 running memory + 4GBeMMC, should be MTK general plan. From the configuration point of view, the GPU is better at this price point, and the CPU may be the bottleneck of system performance. Need to remind everyone is that when the smart TV just came out, the TV's GPU and CPU actually do not have any work, are hard to solve the circuit and the signal access bandwidth is more important. In particular, smart TVs such as Sony's from international manufacturers, MTK those things is responsible for the application, quality control processing does not come this round. However, many machines are now used as mobile phones. It is not a good thing for picture quality because Android does not have color management. In the on-demand zone, casually looking for two films and a fragment of nba (what can be said to be ugly and old for the pupil to draw), the server is quite powerful, 1080p resources are fast, and 30 seconds of advertising time is understandable. In addition, I have to seriously Tucao TV designer, watching any video on demand when there is no way to adjust the brightness contrast color settings such as color (in addition to the remote control on the view button), the menu button can only adjust the film source The clarity and number of sets Although I am an old-fashioned user, I am not too impressed with the TV smart system and I like to download movies or use discs directly. It feels like there is a sense of security, but I have to admit that in this smart age, I really have fallen behind. From the point of view of the majority of users, the convenience and quick enjoyment brought by the intelligent system is far beyond the replacement of non-smart TVs. Changhong's system is generally fluent and free of charge. The price of the built-in penguin theater is not too expensive, and it can be reduced in various ways and even completely free of charge. If the existing resources and software are not satisfied, the 55G6 itself is an Android smart TV, and its scalability is very strong. If you want to find software, you can install all kinds of APPs. There are some minor bugs in the system. I don't know the relationship between the hardware of the machine or the system bug. In addition to restarting the test video, when testing this machine, I also encountered a very slow response from the TV system. Every time you press the remote control, it will take a few seconds for the TV to respond and it cannot be restarted (the ghost of the restart) until the next day. Fourth, quality assessment Finally came to my most valued and should be everyone's more interested in the quality test, first take a look at the selling point of the 55G6 picture quality, in addition to the obvious ad words, I summed up is: 4K + curved screen + dynamic compensation + Direct backlight + zone control + HDR. 4K screen is nothing to say, now the big screen TV is not embarrassed 4K screen. Curved screens can indeed improve the telepresence and the depth of the picture in theory, but the premise is that you should be close enough. Dynamic compensation praise, the other surface TV on this price level does not seem to be. Direct backlight + area control light, I honestly have many good results, I doubt it, first, how many areas are not specified (apparently not too much, with the brand's 60G3 say more than 200 partitions). The second is that the direct-lit backlight is now a cost-saving product compared to the edge-lit backlight (because it does not use a light guide). The color saturation adjustment can also be done without the filter, and can be adjusted in the following manner: First, the color saturation is adjusted to the minimum position, and then the depth of the color is adjusted according to personal preference. However, if the colors are too strong, they will lack realism. If they are too light, they will lose the meaning of color. A more appropriate criterion is that the skin color of the person in the image, especially the color of the hands and face, should be close to that of an ordinary yellow person. The following is the test phase with pictures and videos. Since my screen capture technology is not generally bad (in fact, it is more than just a screen shot and it is a photography idiot), many times it is far from the display effect, but the actual effect of each picture is Will explain, I hope everyone will forgive me. Because "Super HiVi CAST" is not 4K resolution, it also uses a 4k test chart commonly used on the Internet to look at the resolution of 55G6. As can be seen from the figure below, the 55G6 resolution is still good and can be clearly distinguished 4K resolution letter. In the Moving Material test, the panoramas are composed of floral fabrics. Through the combination of different colors and patterns, plus the way the camera moves to the left at a constant speed, the TV is tested for rapid movement in a scene with rich colors. Whether the whole image and edges will be moved It is damaged or interfered. The test is also divided into slow lateral motion and rapid lateral motion. You can see that the slow test 55G6 performance in the law, under the slow motion of the fabric color and square grid clear without smear, color interference is not obvious, the whole movement is relatively fuzzy under fast motion, the color is also significantly affected by interference. In addition, video has a card frame phenomenon is the relationship of photography, the actual is very smooth. At this point, the contents of the "Super HiVi CAST" test have all ended. Let's take a look at 55G6's support for HDR. From the quality tests, we can see that, due to cost, 55G6 does not have a very high standard, and all performances can only be said to be ordinary. However, TVs at this price level cannot be high quality. After all, the quality of this thing, in fact, has nothing to do with technological innovation. It is only related to the cost. I think it is at least worth the price. About 4k can have such a performance, Changhong still moved a lot of thought. Fifth, summary evaluation advantage: 1, the appearance of neat, good workmanship, no domestic brands easy to commit the aesthetic error. 2, the system is easy to use, easy to use, feature-rich. 3, equipped with a rich theater resources, the server speed is very fast, but also through the task to get free members, do not have to worry about resources. 4. The actual surface area of ​​the curved screen is larger than the flat screen of the same size. At the same time, there is a better telepresence and depth of field. 5, there is dynamic compensation technology, dynamic in the same price is better. 6, picture quality worthy of the price. Disadvantages and suggestions: 1. The system has small defects and the supported video formats are not comprehensive enough. It is recommended that the new version system be introduced as soon as possible. 2. HDR video decoding is not fully supported and it is recommended to fully support software upgrade. 3, USB interface is not used 3.0 specification, and with a large capacity mobile hard disk sometimes there will be insufficient power supply. 4. There are hidden corners on the four corners of the screen, and the phenomenon of light leakage is more obvious. 5, whether it is the quality settings or other settings of the machine are not very friendly. Changhong launched the 55G6 at a very attractive price. It took great effort in smart and online cinemas. The advantages of curved screens are also obvious. The targeted crowd should have certain requirements for liveliness and dynamics (such as the ball game). From this point of view, I think Changhong can seize this part of users. Because of the curved screen at this price, the competitiveness of the 55G6 is very high. However, due to the high cost of the curved screen and the overall cost is limited, the effort invested in the reliability and quality of the system is relatively small. If the user does not care about the surface but has higher requirements on the image quality, the 55G6 Not a best choice. 8 Coaxial Speaker,8 Inch Coaxial Driver,8 Inch Coaxial Speaker,8 Inch Coaxial Loudspeaker Guangzhou Yuehang Audio Technology Co., Ltd , https://www.yhspeakers.com
And HX820's remote control made a comparison, at least lightly right it This manual is too much environmental protection, bad reviews! Also, the power cord is double-elbow, and I don't take special pictures anymore. 
Because of the cost restrictions, the 55G6's rear cover does not use steel plates but uses similar imitation leather material plastics that some mobile phones use. 
These interfaces are also regarded as the current mainstream configuration, but for cost-saving considerations, no one USB port is 3.0, this should not be ah. Later, when the mobile hard disk drive was tested, the two USB ports with the 1.5T Toshiba disk often appeared unrecognizable. In order to completely identify the 500G, it was estimated that the power supply was insufficient. The cost can not save much, but it leads to poor customer experience, Changhong is a bit worth the loss 
The thinnest part at the top is about 15mm. The thickness is well controlled. The thickest point is about 60mm. It feels a bit thick. Is it because of the curved surface and the direct backlight? 
As the entire market has adopted a narrow border and a thin and light line, the shape of the TV is now more and more similar to that of a mobile phone. The 55G6 is also not exempt from customs, and there is no particularly overwhelming design that is more concise and simple, and the workmanship is not superb but there is nothing to be done. Special Tucao, the golden bar below is the family characteristics of Changhong TV, and echoes with the base. The point of picking is a slight color difference with the base bracket. 
After a short boot screen, the boot wizard is used to make initial settings. It is necessary to access the home wireless network. Thanks to the possible hardware configuration, there is almost no delay in system input and settings, but in the end it is recommended to install the application is what ghosts, and to recommend trouble points recommend practical points, are mahjong landlords what do you mean? ! 
I like to look at the settings first, Tucao, what is the ghost of the system settings without quality settings, really treat yourself as a computer? ? ? In addition, it is emphasized that the play machine guide must be seen, because the 55G6 manual is almost nothing to say is a trip, the manual function is fully integrated into the play machine guide! For example, the remote control's key description is more detailed and intuitive than the paper manual! 
It is personal center, application, game, education, shopping, music. The application will not say much, in addition to the built-in, but also through the U disk to install applications (APK file), the essence of smart TV is here. Personal center at first glance is useless, but Changhong cooperation with Tencent is a second chess game. The use of Tencent’s huge platform video resources should not be a problem at all, and after registration, you can complete various tasks by watching and operating TV. Collect points for money. According to Changhong's introduction, a rough estimate of a consumer family's normal viewing, can get 65 gold coins a day, a total of 23,725 coins a year (equivalent to 237 yuan), you can enjoy 1 year Tencent video Hollywood membership services and can also spare. In fact, this temptation for office workers is not great, but that can be used to watch older people watching TV at home for more than 8 hours, which can save a lot of money. Education and games and shopping are relatively tasteless. The average user does not care much about these two areas. There are babies at home and the education area may still be useful. As for the game, I still recommend that even a professional game machine be used to play it. . The biggest problem with shopping is that you can't buy it directly on the TV. You also have to call or download the app. This column is not worth mentioning. Music is not expected to be used by users. Is it possible to use TV as music as a chore and background for domestic chores? 
4K area to find a port to look at, but to experience the 4K image quality must be scanned with a mobile phone to scan the two-dimensional code to see, although troublesome but understandable, at least you do not have to pay for it. The speed is still satisfying. Loading, fast-forwarding, and the time needed to load the progress bar are negligible. Ma Huateng has spent a lot of money this time. The image quality level is certainly not a normal 4K standard. It is estimated that, like 1080p above, the bit rate compression is too severe, and the pursuit of picture quality may be disappointing, so the smoothness and picture quality cannot be achieved. So if you look at it casually, it's still good. If you are looking for quality, you can still download it by yourself. These two figures are the contrast between the UMAX viewing mode (the second picture) and the closing (the third picture). After the UMAX viewing mode is turned on, the human skin color is more realistic and the sound surround effect is very obvious (but the effect is I dare not to compliment. But the transparency has dropped. I suggest that you can turn it on while watching a movie. You don't have to watch a TV show. 
There is also a penguin theater, 25 yuan a month, it is still a little expensive, but it should be able to do the task every day, and finally watch free of charge. 
Specially downloaded the security Bunny video test, want to test the decoding ability of 55G6 video playback, who knows that at the end of the test, the TV display Huaping then restarted, and tried three times are so 
Why do you have questions about HDR playing question marks? Because the Changhong official website did not say that 55G6 supports HDR, but it was written on the Jingdong 55G6 page (see above). HDR is a very hot technology recently. I am very optimistic about it. Compared to 4K and curved surfaces, I think HDR is an epoch-making progress. If the previous SDR films limited the quality of high-quality TVs, then the only thing that limits the HDR movie quality in the future is the TV itself. HDR is a hardware + software + content trinity system. The first thing to do is to capture HDR video using an HDR camera; second is that the TV supports HDR technology and has a corresponding ability to decode HDR video; and finally the requirement for the TV hardware to fully display HDR video. It is worth noting that most HDR LCD TVs in the market today are only HDR-compatible, and only HDR decoding capabilities do not have sufficient HDR reduction capabilities. Does the 55G6 have HDR decoding capability? I'll sell it first 
Because there is no professional instrument (can not afford), so specifically to buy a "Super HiVi CAST" DTS Blu-ray HD test disc. For TV enthusiasts who are not particularly feverish, this is a god dish. It can not only make adjustments to televisions, but also can be used for TV tests. Highly recommended! 
Adjust the white level of the TV first. If the 107% area of ​​the center of the picture can be seen by the naked eye (with a clear border with 100% area), it means that the white level setting is incorrect, and the contrast needs to be adjusted until the above figure can only display to the 100% boundary and other percentages. The area can be clearly identified. 55G6 default 50 contrast on the line. PS: The same disc player, my home that hx820 how to adjust can see the ultra-white area, ask for advice 
Then adjust the brightness so that the naked eye can see the adjacent boundaries of each area. Another 0% area has a superblack area in the middle. This area should not be seen after adjustment. 55G6 will increase the brightness to 64. 
This is a hue adjustment, which is a block diagram for observing the composition of cyan and magenta through the blue filter provided with the dish (this is why I spend money to buy the dish instead of downloading it). Should be as consistent as possible. Changhong designers have made moths again this time, there is no option to adjust the tone! ! ! ! With the color temperature adjustment option on the picture (and there are also three colors), trying for a long time is useless! ! ! Can only be adjusted 
This is to adjust the saturation of the color, which is the vividness of the color. It is still a block diagram of blue and white observation through the blue filter. The two colors should be as consistent as possible after the saturation adjustment. This time, the 55G6 finally had no moths and the contrast was adjusted to 46. 
This is to adjust the sharpness, the point is that the following lines can be clearly distinguished, there can be no noise between the black and white grids in the middle. However, this is very easy for LCD TVs. I did not make any adjustments. 
The Monoscope (1920X1280) is a test that measures the line-by-line, skew, circular, sharpness, grayscale, overscan, and other 1080p progressive performance. This is still very easy for a 4K machine. The 4-week circle is smooth, there is no ghost in the inner circle, and the slanted lines are clear. 
I am not very kind with a 0.4% brightness black screen for testing, the purpose is to abolish the 55G6's light control function. The first picture fully embodies the advantages of a direct-lit backlight. You shouldn’t be scared by this figure. This is a camera (photographing technology) pot. The actual effect is far better than this. Of course, the phenomenon of light leakage is still obvious. . However, I can tell you responsibly that light leakage does not have much impact on the viewing effect in most cases. The second picture is to shoot the black side of the 4:3 picture of the TV. You see this level of light leakage is much better. 
55G6 display white screen makes me a bit disappointed, uniformity is not good I can understand, after all, the low-end machine uniformity is not very good, but the four corners have more obvious dark corners, I guess it is because the surface of the curved screen requires higher backlight Caused by the lack of transparency of the relationship between the four corners. 
Text (Black back Red character) test on the black text can not only reflect the TV text display ability, but also more accurately reflect the display ability on the red. 55G6 has no problem with text performance, and the biggest advantage of 4k resolution lies in this. Red is also more vivid, but the size of different fonts will be different shades of red, the middle part of the pixel with white instead of red phenomenon. 
DARK COLOR is a metamorphic test video. It mainly looks at the color cast of various colors in the high and low light areas, and the color brightness and color gamut failure at low brightness. 55G6 is obviously incapable of dealing with this picture. The situation in the low-light zone is not to mention color, and even the grid can barely be identified. However, this price is not strong, you must know that at low brightness, only Sony's steoled can only make the difference between the brightness and the color is no difference. 
Color Triangle is a color test for televisions. The separation of each color block is viewed with the naked eye. The requirement is that the color blocks can be separated clearly but they cannot be cross-colored, and the machine color requirements are relatively high. 55G6 performance at least in this link is still worthy of the price, easy to separate or separate relatively clearly, the performance of green blue is not very good, the left part of the yellow also performed in general, red and orange performed well. 
The Scroll Multi Pattern (640Pixel/Sec, 1280Pixel/Sec, 1920Pixel/Sec) is a dynamic test video composed of three different grayscales including the same straight line, diagonal lines, and a rotating disk composed of straight lines. According to different speeds, there are three different levels of difficulty to complete a 1920-wide image playback for 3 seconds, 2 seconds and 1 second respectively. Given the 55G6 has dynamic compensation technology, 640Pixel/Sec is still good in this test, 1280Pixel/Sec is unsatisfactory, 1920Pixel/Sec miserable (but this difficulty is indeed a metamorphosis). 
The BLACK AND WHITE (B/W BACK) test level is the ability of the TV to display white and black under the black and white background. From the test picture, the 55G6 display white ability is obviously better than the black ability. Saying that this beautiful Indian woman is smiling and charming 
Static Color tests the color expression of static objects, outline details, screen noise suppression capabilities, color accuracy, and more. 55G6 color performance is relatively outstanding, although the texture is not Feng (This is no way to do, LCD texture to do a good investment) but the color accuracy can be accepted, the disadvantage is that black cashmere can not be clearly distinguished, the ability to suppress the noise is very general . 
The results are pit father, 5 video, 3 can not be played, 1 second after normal play, the color becomes very strange, the first picture is the correct way to open this should not be a hardware problem, I hope Changhong patch quickly corrected . 
When playing a 4K source, it was found that the 55G6 had insufficient support for decoding the 4K source. All of the same were TS files. One could put another but could not. However, 55G6 performed well in the aspect of picture quality. The details were almost complete and the colors were basically accurate. At the same time, the curved screen also led to better depth of field and presence. 
Top down: "Super HiVi CAST" Blu-ray demo video, 1080p movie, 1080p TV drama, 720p TV drama. The performance of 55G6 on non-4K screens is not beyond my expectation. In the case that the film source is relatively good, the basic expressiveness is still there. The biggest drawback is that it is not transparent enough and the skin color is not acceptable. In the movie of the Big Bang at the end, the 55G6 should not be optimized and the picture is rough.
