I am very honored to be featured in the weekly excellent original article, thank you for your support and opinions, thanks to Xiao Bian, thank you for Aunt Zhang.
After the home renovation, the purchase of home appliances is also a very important part, then as the scales immersed in the emperor's broiler, they will start to talk about the process of buying television research and selection.
Before everything, first of all, let's summarize the TV screening principles that we can use to make a toast!
Determine the requirements and budget scope (cooked boiled demand is a large size, good display point can play games with the paper, the budget more than 1w ... ...)
Identify alternative brands
Within the scope of the budget, there is a preliminary plan for the purchase size. It is very important to determine the size. If the budget of 1W is to buy a 70-inch TV, the available space is very small. It is OK to pick one like it and the brand can be bought easily, but if you want to use a budget Buy a 55-inch TV, then scratch your head.)
Look at the real machine at the scene (to determine the alternative model, do not just look at propaganda, really different after comparison)
Based on the alternative model, select the desired appearance (Why the appearance believes me, after determining the above points, the value of the color is the decisive factor)
I believe that many value-friends are like boiled cooks. They will do their homework before buying something. The purpose of this is to only buy the most suitable ones for themselves. Doing homework is a short-cut for Auntie Zhang and professional forums. It is also a quick way to understand the development trend of the industry and major technologies. Because home appliances are different from other electronic products, they have a long life cycle. As an ordinary consumer, it is difficult to grasp the development of the industry in a timely manner. Latest News.
However, the bubble bubble, some of the information is also need to be our own screening, to identify, because the election is right for their own is the best.
(1) My View on TV "Buying Old and Not Buying New"
I believe that experienced value-friends know that for the TV category, the forum is filled with a voice that "because the manufacturing shrinks and buy the old (old model) does not buy new", but we admit that shrinking phenomenon does exist, but also To think, "buy the old" really feasible?
TV as a black, fast replacement, new products will be introduced every year, and the product was discontinued gradually last year, for some of the so-called "price" of the old models, my understanding is neither exclusive, nor excessive pursuit, if the purchase of When it happened to meet a new inventory of merchants, the price was right to start, but there was no need to buy “old†exclusively because after the old model was discontinued, there was a large part of the circulated machine except the used model. As an unprofessional consumer, there are considerable risks in buying these older models.
(2) 4K uselessness
Some of my friends will have such doubts when shopping for TVs. Now that there are fewer 4K sources and the network bandwidth is not enough, is it necessary to buy a 4K TV?
Indeed, based on the above arguments, currently 4K is indeed a bit "cheap", but the actual point is that if you do not buy low-end entry and television, in the environment of manufacturers pushing 4K, there are already few 2K models on the market. Combined with the risk of buying “old†above, can we really buy the right 2K TV?
Therefore, do not confuse the current 4K can not be used, the entry model may be 2K resolution and other options, because the price is relatively low, can be replaced with a few years and other popular 4K, but in addition to halogen cook feel completely Don't worry about 4K. How many years ago could anyone think of a 50-inch TV that could be bought for more than 2,000? Never underestimate the speed of technological development
Process 2: Some Things to Know About Buying Television IPS hard screen is not the standard for the quality of the panel
Do not know when to start, some TV manufacturers began to advertise in the advertisement of products like "using the original IPS hard screen" like a gimmick, giving the impression that IPS hard screen is a tall thing, only the use of IPS screen products It is a good product.
IPS technology is mainly used by LG Display, while the main manufacturers using VA screen include Samsung, Sharp, and AU Optronics.
The most intuitive difference between the hard screen and the soft screen is that the soft screen will appear to have water ripple effect, as follows:
The so-called soft screen and hard screen, the essential difference is not "soft" or "hard", LCD panel types are different, the main difference lies in the realization of different visual angle technology; and the fundamental difference between the two lies in the arrangement of liquid crystal molecules The way is different. The hard screen and the soft screen are also the physical structure of the liquid crystal. The hard screen liquid crystal molecules are arranged horizontally, and the soft screen is arranged vertically. In many standards relating to the performance of LCD screens promulgated by the international or domestic industry, "soft screen" and "hard screen" have never been classified as a major criterion for distinguishing between merits and demerits.
It can't be denied that the IPS screen has the advantages of larger viewing angle, true color, and superior dynamic picture quality compared to ordinary screens.
However, whether hard screen or soft screen, there are advantages and disadvantages of the grade points, the same level, the same price is comparable, and put aside these factors simply emphasize the panel type, can not avoid being evasive light suspect (rogue). In addition, the factors that determine the display effect of TV products lie in the level of the LCD panel. Another important factor lies in the technical level of the manufacturer, the driving performance of the core chip, and the optimization algorithm for the image. For the latter, at present, all manufacturers are still in the stage of “kings selling melons,†and as ordinary consumers, we often have no idea what to say about these professions or terms. The best way to judge whether you are better or worse is to go to the scene and see, eyes will not deceive us .
Here I suggest to everyone is to bring a high-definition film source (preferred to reflect the color, light and shade, metal texture and other perspectives, recommended: Transformers 4) to the site to experience, do not simply look at the store's cover sheet.
TV size selection
There are many different algorithms for the viewing distances corresponding to different TV sizes, and the authoritativeness of each algorithm cannot be verified by boiling. However, fortunately, the data gaps obtained by various algorithms are not large, and it can be used as a value-added TV when you buy TVs. The reference distance.
First of all, line-of-sight does not mean the size of the open space in our living room, but our normal viewing is the distance from the eyes to the screen.
So there are roughly two algorithms for the best viewing distance in 1080P resolution, as follows:
(1) 3 times the height of the display area
(2) According to Apple's retina theory and formula, when the viewing distance is 1.56 times the screen size, the individual pixels cannot be distinguished by the naked eye.
Take a 65-inch TV as an example: 3 times the display area height = 80.933 = 242cm
Screen size 1.56 times = 165.11.56 = 257cm
Therefore, as long as the viewing distance is 2.5-2.6 meters, 65-inch TV can be started.
When I was little, my parents would always say us. Watching TV was so close that my eyes would be embarrassed. Sure enough, then many of us were wearing glasses. Therefore, we more or less think that watching TV too close will affect Visual acuity, but in fact, it is more important to master the degree of goodness. A reasonable distance to watch TV properly, and then give your eyes ample rest time is king!
Response time
LCD TVs achieve picture changes through changes in liquid crystal molecules. It takes a certain amount of time for the liquid crystal molecules to receive the signal and complete the change. This time is the "response time." Response time is an important performance indicator of LCD TVs, also called response speed, and the unit is usually milliseconds. The strict definition is the speed at which each pixel of the LCD TV reacts to the input signal, that is, the time it takes for the pixel to turn dark or turn from bright to dark. It can be said that the response time of the LCD TV represents the reaction speed of the screen. The slow motion picture caused by the slow response time has also become a major shortcoming of flat panel TVs, so try to choose a product with a shorter response time.
But how to deal with the parameters of scalar? The answer is still with the eyes
Color depth technology
Nowadays TV manufacturers are promoting some high-end TVs, we can often see words like “1.07 billion color wide color gamut.†In fact, it is color depth technology, with bits as the unit, those who claim the wide color gamut, 1.07 billion colors. The product is actually a 10bit panel. For the difference between the 10bit panel and the 8bit panel, the following diagram can be displayed very intuitively, but the price difference between the two panels is also intuitive, how to choose depends on the actual needs of everyone.
â–³ 10bit panel to make the level between the natural more smooth and even, generally 8bit panel reaches 256 grayscale, and 10bit has 1024 grayscale, the more the number of gray scale more fine, the color transition is more uniform.
Double Speed ​​Drive Technology (Dafa Motionflow Technology)
In order to improve the phenomenon of smearing of LCD TVs, the major manufacturers can also be said to have a comparative advantage. Under such circumstances, double-speed drive technology came into being. One of the most famous ones was Dafa's Motionflow.
There is no delay in the motion picture seen by our eyes. However, the dynamic images displayed on the LCD TV are all composed of a frame of static images, which causes the displayed image to be delayed anyway. In theory, the more static frames (frames) that are displayed at the same time, the clearer the motion picture image and the less smeared. Therefore, the liquid crystal television inserts the picture frame again after correlation calculation between the dynamic picture frame and the frame, so as to achieve the purpose of reducing the dynamic picture smearing, which is the double speed driving technology. The double speed drive technology optimizes the dynamic effects of LCD TVs through motion estimation and frame interpolation compensation methods. The so-called "double speed" is to increase the refresh frequency of the driver from 50Hz to 100Hz or 200Hz, and insert an operation between the original frames to obtain an "intermediate picture", thereby enhancing the performance of the television on the moving picture.
Motionflow Technology Small Science:
Motionflow is divided into three types:
1. Frame interpolation (MEMC) - Early use of Dafa, basically used on LCD TVs with CCFL backlight
2. MEMC + Backlight blinking - LED backlighting era began to gradually adopt
3. Sweeping - The Dynamic Effect Improvement Techniques for Low-End Models in the LED Backlight Era Without Pins
Interpolation frames are interpolated calculation frames instead of black frames, which can effectively improve the fluency of the image, but may cause errors due to the complexity of the screen.
Sweeping eliminates the residual vision of the image by quickly closing the backlight to simulate the insertion of black frames (but better than inserting a black frame), and improves the residual of the transition between frames caused by slow response of the liquid crystal molecules.
â–³ Dafa Japan's official website for the screenshot of the frequency multiplier technology (Japan official website 8000C parameter is XR240)
Affected by the rapid development of e-commerce, more people are willing to sit at a computer to go shopping, including large appliances, but the disadvantage of this shopping method is that there is no intuitive feeling, and more often is our own delusions. . Therefore, even if it is now, on-site viewing of real machines and measured results are very practical ways to buy favorite television products, although we do not understand the relevant technologies, but our own feelings are real, comfortable after reading Comfortable, cool, no one knows better than yourself.
Say so much, I feel quite boring, here's still take a look at Dafa's 75X8500C in the end how to put!
SONY 75X8500C debut ÂWhat, want to see big sister, wait!
(1) Appearanceâ–³ Yes, the protagonist is this guy, or the phrase, some products, entities are really cheaper than e-commerce, do not superstition e-commerce
â–³ Behemoths, when they went upstairs, entered the door, and installed, they also spent a staggering amount of time. The master worked hard.
â–³ LOGO is also credited with faith recharging. When his son can play video games, he may continue to charge.
â–³ thickness of 75-inch thickness, then it is OK, although the ratio is not on the 9100C, after making a choice on the price, this is considered a better choice. Although the large thermal X9000C corresponding to the 75-inch model is 9100C, but 9100C can not achieve 65-inch 9000C 4.9mm thickness, visible 75-inch and 65-inch products in the process, cooling and other aspects there is still a big difference ~
â–³ interface is rich, but only with a USB3.0 interface, and not on the side, really ...... TV has been installed, it is really struggling to move it, the interface from the angle of the guests will see it
â–³ minus allocation? Indeed, it can be seen from the remote control. The Dafa remote control on the right looks lower than the HD set-top box remote control on the left side. The previous Dafa remote control also has a backlight like the BenQ remote control (left one), but fortunately the remote control setting is better and the function is faster. The keys are easy to use, the touchpad remote control adds voice, and the voice is super high
â–³ Design & workmanship. This matt brushed silver edge and light base do not know Dafa from what angles to consider, it does not really look good at first, but the 75-inch 9100C price is seriously over budget, or choose it, see more and better workmanship can be Outstanding, borders and screens are tightly stitched together
â–³ delivery installation day I was not at home, LD tracking, installation of the machine test chart, the overall effect is also coordinated, my family's 8-year-old TV cabinet did not look too
(B) Function and Display EffectAll the following pictures are screen shots, because there are a series of influencing factors such as shooting technology, metering, website compression, display color difference, etc., and there is a certain gap between the picture and the actual display effect, which is for reference only. All pictures have not been processed
1, basic test
â–³ color test
Pure and bright colors, hidden corner from the camera
â–³ leak test
No obvious light leakage, more satisfactory
2, some of the main features
For the settings and functions, because the content involved is relatively large, so the basic things are not involved, highlight the key ~
â–³ Setting menu
The “Quick Window†button of the remote control calls out the related setting menu, and can quickly set the image, sound and other settings in combination with the actual needs and the preferences of the user while playing the image.
â–³ Image setting
The setting of Dafa image settings is really powerful. PS: High-definition TV shows can clearly see the king's facial details, beard, hair details are complete.
â–³ Image mode
Braised missed the "photo - user settings" mode, so the total number of image modes up to 13 kinds, you can easily switch according to the content and needs of the broadcast, so easy can see HDR video image mode settings, but boiled Haven't tried HDR video resources yet
â–³ Motionflow setting
Motionflow can be turned off everyday. Watching movies can open the real movie mode. Turning on the smooth mode will cause some loss of quality due to rendering errors, and it will only be used in intense sports programs.
â–³ Voice search
The voice search is Baidu search, the recognition rate is very high, and the current normal speech rate test has been cooked, there has not been a case of identification error, is it possible that the Mandarin standard is too standard?
â–³ Video resources
The video source cooperates with China TV, and many of the boxes are useless. Although there is a 4K column inside, what is the current speed to transmit 4K video?
â–³ 4K video has "4K" logo in the lower left corner of the icon
Here I have to mention the player that comes with Dafa TV. Braised downloaded some 4K video resources to experience the changes brought about by 4K and test TV performance. Some of the videos were in TS format, and the players installed in the Braised Computer could not play normal format videos, but Dafa TV The video player with the smooth recognition and playback, and the whole smooth without any abnormalities, it can be seen, the built-in player performance is strong, the video type supported is more comprehensive, very good
3, display effect
Hold your breath and my sisters are here
â–³ HD, SD TV program comparison
From the picture, we can see the difference in the details of the hair of the goddess, but the effect of the SD video is completely acceptable. The facial color, the details of the fur worn, and the layering of the background are all still good, because the price of the bedroom equipment Only close to the Dafa fraction, there is no comparability, and no comparison is made here. Overall, the optimization of SD video by Dafa is still obvious.
â–³ HD movie
The natural transition of the image color is natural, and the dark details and layering are performed well.
â–³ 4k Transformers Trailer
The metallic luster of the body part of Optimus Prime is vivid, the details of the dark part below the head are clearly visible, and the level of the forest background is vivid.
â–³ 4K static picture
A variety of light and dark, light green gums mixed together, the color is true, the transition is soft and natural, looks very comfortable
â–³ 4K roast duck beauty
According to convention, you must get the beauty of roast duck.
â–³ attractive roast duck
Whether or not you have appetite after reading, anyway, I have
Welfare time arrives
â–³ 4k static sister screen shot (skin color, hair)
â–³ T-ARA 4k MV video screen (hair texture and gloss, as well as that lip)
â–³ It cannot be a little welfare, right?
What, what big bike would you like to have, how can I tell you who is in my hard drive?
For the use of the 8500C experience: Technically speaking, the 8500C covers the X1 chip, Terricolor, Motionflow 800, long tube speaker (65, 75-inch configuration), etc., which can fully meet the needs of my non-experienced friends to enhance my audio and video experience;
Appearance and interface design, taking into account the size of 75 inches, the overall thickness of the machine is still satisfactory, except that the silver edge of the design is indeed not so pleasing, but more can see it. Interface settings enough to meet the daily needs, but really want to save the cost to this point, on a USB3.0 interface, but also behind, I plug a U disk is very strenuous!
Judging from the effect of actual use, SDTV programs have no graininess, sawtooth sensation, and full and natural colors. High-definition video is rich in details, exaggerated in naturalness, and has a strong sense of depth and darkness. 4K videos can be described in terms of shock and longevity. The sound quality that the duct loudspeaker brings is promoted, in the situation of 4K resources is not much, even if it is to look at mv, can bring the feeling that is immersive on the scene, the character vividly rises above the screen. A variety of image modes and Motionflow mode Whatever your personal preference, there is always a fast and easy way to operate. It is easy to change and change. It is easy to match the gaming experience of the game console. You may have to wait for the paper. The big point will be added again.
Written at the end:The choice of television is in fact limited by many factors, such as budget, space, purpose, preferences, etc. Therefore, it is attributed to the fact that everyone's actual demand for television is different. Therefore, we should not use our own needs to evaluate other people's choices. We only need to figure out our own needs before purchasing. Is it more usual to watch TV or watch more movies? Is there any potential demand for playing games? What is the demand for video effects? Or maybe I don’t watch TV at all, buy it in the living room as an accessory, and so on, and only after we have clearly identified the needs can we choose the TV that suits us best.
It is better not to have such a situation: When Zhang Mother broke a TV offer message, she immediately asked “How about this TV? Worth is worth itâ€. The answers to this question are all targeted if there is no targeted improvement. "My demand is to watch high-definition movies more occasionally watching TV. Is this TV suitable for me?" In fact, it is not difficult to choose the right TV for yourself, is it not?
In the end, that sentence, there is the opportunity to go to the store to experience it personally, to understand the true needs of their eyes, to walk more, to have less regret, and finally to wish everyone all to buy the most desirable TV for the most value for themselves.
