Xiao Bian Note: This article is long and carefully read, it will take at least 120 minutes. Before the Spring Festival, he wrote " Talking about flat-panel TVs (mainly LCD-based) (Part I) - Suggestions ". Thanks to the love of valued friends, I gave a lot of feedback and encouragement. Although we have been surfing the Internet during the Spring Festival, because we have to bring children at home, there are many things, so we usually answer questions and comments from everyone. Recently, I finally had a free time and promised to do something worthy of your friends. So I immediately started to write the second article - those companies don't tell you about the service. The article has also received strong support and professional guidance from TV industry professionals, Lao Ba. Many of the reports were provided by the old eighty-one players. We would like to express our special thanks to this good friend. First, the fate of destiny - the plasma tragedy Remember when the tablet just emerged, the plasma is absolutely high and handsome, Pioneer , Panasonic , Hitachi at the time of the high-end machines, to quality and quality, to have a look, price to price , All the big size. Pioneer 600A, Panasonic PZ880, Hitachi 60, and 50X101C were classic generations at the time (Hitachi may be slightly weaker, but its price/performance ratio is unbeatable). In contrast, at that time, apart from the few high-priced liquid crystals of sony and sharp , LCDs were obviously short and poor, and they could only take the small cost-effective route. However, when the time passed, the Pioneer was reduced to a purely domestic brand in China, and Hitachi has disappeared. The Panasonic who has been struggling to support it has also turned its focus to led and future oled . The destruction of plasma is just around the corner. As a plasma fan who has never bought a plasma (it's a mouthful of words), I feel like I'm worried. In fact, since plasma was invented, the confrontation of LCD with the same quality has never lost. Certain congenital advantages of plasma quality are really unmatched by LCD, mainly in four aspects: One is the color texture (and the most critical). Maybe this is difficult for everyone to understand, I posted a big message to the appliance forum ken: "In real life, in fact, everything has its own specific luster or texture. This makes the object appear real and it must be displayed on television. The actual texture and gloss of the camera is very difficult, and this concept is the natural advantage of plasma TV, which will make the objects displayed on the plasma TV appear more realistic and realistic.The LCD can only use 256 gray scales unless the 10bit panel +10bit is used. Material LUT mapping can get close to plasma TV's texture and gloss in this respect." However, even if the 12bit panel + 12bit material LUT mapping xs1a, in the performance of human skin color, can not do high-end plasma texture, perhaps only qulia005 can do; second is dynamic, plasma can be said to have no natural smear, relatively speaking What kind of speed, 200hz panel and other technology LCD really weak burst; Third, the dark parts are excellent, there will be no light leakage; Fourth, relatively protection of vision, suitable for children (especially compared to the current WLED backlight LCD).    Unfortunately, the plasma has small technical defects at the beginning, and the shadow of burned screens is still remembered by everyone. At 08 time I gave up the better quality pz880 and chose w380a . At present, although the defects of burning screens have been basically solved, in the process of matching costs, the quality of the plasma that requires higher quality stability is more unstable. In the 12 years I was born out of black belt doors of the Panasonic series. Get on the Sony 55hx820. The paradox is that the black belt is more concentrated in the high-end VT, GT, ST series, the low-end ut, xt series black belt is not too much, do not know how Panasonic quality control. But even if you set aside the burning screen and the black belt, the decline of plasma in the domestic market is also doomed. When the low-end LCDs have reached the “Kangzhuang Avenue†with 4 K resolution, we have many plasmas that are 1024,768. The wonderful resolution, the parameters of the party certainly do not see the plasma (to be honest I do not see). And in the bright environment of the store, the plasma quality advantage sometimes cannot be reflected. Instead, the high-brightness liquid crystal is more eye-catching, and the plasma with slightly lower brightness will appear flickering and dim, and consumers can't compare after taking home. Can not know the advantages of plasma. There is also an important reason why Japanese manufacturers who are dedicated to plasma production, marketing levels, cost control capabilities, and innovative ideas have not been able to compare with Korean manufacturers who are dedicated to producing LCDs in recent years. They are also far less like gold letters on sony and sharp tablets. signs, the only slightly in 11 years to compete Panasonic Black Belt scandal and 12 years later sold at a loss e8000 Samsung can not rise again, 13 years Panasonic's VT60 series 60 in addition to the other is simply smashing plasma signs, with Samsung e8000 Gaosi After Panasonic took P trash to make money, LG walked the low-end cost-effective route, plasma seems to really disappear on the flat stage. If you want to buy plasma, my recommendation is to find Panasonic old goods, I know someone bought a plasma machine 65pz880z and 10, 20 series of Panasonic plasma last year. Of course, if anyone has the ability to get pioneering plasma, you must not miss the opportunity! ! This year, the only plasma that can be bought is LG's 5xxx 60-inch bar, at least cost-effective enough. About the dispute of crystal powder and other powder I have to say two more, crystal powder always love to say that plasma burn screen life is short, large energy consumption, and other powder always love to say that the liquid crystal hurts the bad eyes, but it is not necessary at all. From the perspective of light source life, plasma life is longer than ccfl, not as wled; from the health point of view wled is the most wounded eye, ccfl slightly better, plasma is best (but the premise is not flashing plasma), can I say wled This cargo is stinking and long.    Second, a good bubble - 4K TV's way of making money First put a Baidu text: "4K, is the resolution standard for a new generation of Hollywood movies. It is different from the so-called high-definition television (1080P, 1920 × 1080 resolution) we see at home, but also different from the traditional 2K resolution of digital cinema The big screen (2048 x 1080 resolution) is an ultra-fine picture with a resolution of 4096 x 2160. Using a simple metaphor: The HDTV you see at home is a 2.07-megapixel picture, but in the traditional digital cinema What I see is a 221-megapixel picture, and in the 4K cinema, I can see a high-definition picture of 8.85 million pixels, which can be distinguished at one glance. 4096×2160 by Digital Cinema Initiative (DCI) The organization promotes members including Disney, 20th Century Fox, MGM, Sony Entertainment, Universal, Warner Bros. and many other major movie studios." Sounds awkward, is 4K TV really useful? In theory, yes. Because of the screen size of the TV, the resolution of 4K is far from the limits of the human eye. I think that the brain could make up for it. The resolution of the screen of 2133312000 with a 60-inch screen may be considered as the screen of the retina. It looks like there is plenty of room to play. Friends who have been to sonystyle should have the impression that sony's domineering 84x9000a ( Sony/Sony KD-84X9000 84-inch LED LCD TV 3D TV ) gives the best viewing distance is more than 1m, that is sony this 4k black actually already It implies that we have 84 inches at a distance of more than 1m, and 4k (cai) has obvious advantages in details. I also did an experiment before writing this article. My home 65xs1a TV screen is about 1400mm wide, and there are 1980 pixels in the horizontal direction. The pixel size is almost 0.7mmx0.7mm, and I took a test on the ruler (visual correction to 1.0), I couldn't see the 1mm scale basically beyond 1.5m. That 0.7mm estimated more than 1m2 can not tell. For me, from a purely clear point of view, a 60-65-inch 4k TV is basically meaningless beyond 1.5m. In fact, there is a better way to experiment, is to do 2k pixel map and 4k pixel map, to see how much distance the human eye can distinguish, but I really too lazy to do it. So surely someone will say, 4k TV is no matter how kind compared to 2k TV is also a progress, say I just like to look closer (big brother your eyes stand it?)! 4k TV is definitely better than 2k TV This sentence is true from the general direction, but there are two major premise, the same as other conditions, 4K source. The first major premise has ceased to exist under the ever-shrinking environment. Sharpness is not only a matter of panel resolution, but also has a lot to do with panel data, TV chips, and tuning. (About the shrinking thing, I The following will be described in detail; The second major premise in the country even 1080p or even 720p film sources are not universal 4k film source is far from reach (1080p HD movies must be more than a dozen G, 4k words, over a hundred G. There is no pressure, just because our mainland network is under pressure.) It is also hopeful to quench the thirst. The key is that without good algorithms and optimized chips, 4k TVs can not perfectly handle 1080p and 720p sources! in conclusion: 1,4k TV is of little or no significance to consumers, but it is of great significance to the manufacturers of this industry chain (TV producers, movie makers, and even hard disk companies). This is the last magic weapon they continue to continue with. Although 5 and 4k TVs are of little significance, the 4k signal has a certain significance. In the current civilian-class YUV420 signal specification, the 4k signal on a 4k TV set is: 3840x2160 luma channel + 1920x1080 chroma channel + 1920x1080 chroma channel; on a 2k TV set: oversampled 1920x1080 luma channel + 1920x1080 chroma channel + 1920x1080 chroma channel . Therefore, the increase in color levels, detail, and texture effects is more important than the so-called definition optimization, which is the welfare enjoyed by both 2k and 4k TVs (of course theoretically, the 4k machines benefit a little more). The 2K peak model will thus exert its full potential. This picture is so beautiful that I dare not look at Kazakhstan. (This section of professional news is provided by the old eight) By the way, one of the new 4k sony machines, only from the parameter analysis, x9500b good but in the country looks like 85 then a size, x9000b is better than x9000a, and x8500b is garbage, do not touch! ! Third, the helplessness of sack change grass bags - talk about the generation of flat-panel TVs as a generation This is a very sensitive topic. It holds a positive view that with the progress of technology, flat-panel TVs are getting better and better. The negative view is that as the cost continues to shrink, the generation of flat-panel TVs is not as good as it was. Constantly, there have been a lot of grudges and hatreds, but for the time being it is not shown. If you want me to come to a conclusion, that is, in addition to quality, workmanship and machine quality, other aspects of flat-panel TVs are improving, more and more functions, the machine is getting thinner and thinner and the frame is getting smaller and smaller (forgive me I didn't use pretty The word, because I think the TV is not classical enough now, the size is bigger and bigger, the most important thing is that the price is getting cheaper and cheaper. However, the core function, quality and quality, is indeed a real recession. Strictly speaking, after the peak of 2007-08, plasma and liquid crystals are shrinking step by step. There will certainly be people who raise different opinions, just as in the first article, some brothers commented on how televisions, such as electronic products, will be inferior to one generation. Technology is constantly improving. Here I would like to tell you, many people say that television is the electronic industry is an electronic product, electronic sister ah, the electronic industry has evolved year after year because of the progress of technology so Moore's Law exists. However, for TVs, the LCD panel is only electronic manufacturing and Moore's Law does not work at all. The backlight components and electronic products also cannot be hit by eights. The plasma panel is not to mention, that is, the chip and the electronics have a little relationship, but The chip technology of the TV has not improved for years. Let's say air-conditioning washing machine refrigerator now has a chip computer version how do you not say that they are the electronics industry! ! Saying that the refrigerator's air conditioner's shrinking, everyone should know, I'm not popular. In fact, the display technology is really progressing, but good technology you can use it for the sake of cost. I also admit that manufacturing costs are lower, and if companies insist on taking the quality line, they can achieve better picture quality than the original player at a lower cost. For example, if RGBLED can persist in the year, it may be similar to 55x4500. Such a machine only 2-3 million. Unfortunately, televisions from the era of high-quality, high-price, giant profits in the 1990s to the current era of meager profit-making with low-cost and low-cost prices (this point is made by domestically-made TVs, the overall price reduction is still a good thing for us), and now manufacturers are making profits. The rate is more to obliterate the original technology, or to shrink in the selection of materials and materials. At the same time, the enrichment of entertainment equipment, the family's pursuit of TV picture quality is also an important external factor in the decline of picture quality. From another point of view, the decline in picture quality is not a bad thing, because the price has also fallen, but I'm angry that the flagship or the same generation is not as good as the first generation, and the price is cheaper. Previous generations of products can now commit the present What do you mean by new products? ! (For example, in the middle of V440, the color level was better than that of the current W9XX series...) Although the price reduction is very popular with most consumers, it is also for some high-end consumers (the local tyrants are also pursuing ah) and want to buy a good TV. No, you have to know that even the Pioneer does not have to buy in China at present, so many people vomit that it is an era when they can't buy good TV. What is even more unacceptable is that sometimes the new generation is more expensive than the older ones because of some more gimmicks. For example, the price of 65x9000a and 55x9000a is higher than 65hx950 and 55hx950. "Revolutionary" 4K, but the picture quality or hx950 is good! ! Now that manufacturers are shrinking and becoming more and more mad, they are getting more and more hidden and smart. Speaking of the panel, Samsung's top black crystal panel used to be the end of the B8000 series in 2009, and later the panel is the cost of shrinking goods, there is no original black crystal deep; Panasonic LCD will give up the invincible IPS-a panel Some tech (gao) technologies are not as good as the previous IPS-a panels. The WT60 does not even use the cheaper LGips screen. The DT60 simply uses the AUO screen; sharp play concept, what four-color screen, even the four-color screen, the first-generation four-color screen ff1a, lv925 panel is in accordance with the chromatographic distribution of the color machine, the latter four-color machine By superimposing the gain, the superimposition gain is low in cost but is likely to cause color imbalance, so behind the four-color machine yellow flooding over other colors; LG is not familiar, sony did not produce the panel I let them off The shrinkage of the plasma panel I specifically listed a piece of material from the old eight, and looked really sad! Panasonic plasma panel phosphor formulations have been shrinking since V10. The first generation of NEOPDP has used lower cost, narrower luminescent bandwidth, and afterglow effects to improve luminous efficiency. (Note: The afterglow effect greatly affects the color texture. The disadvantage of LED backlight is that There is no afterglow effect, so it has always been difficult to have the taste of that kind of movie. Machines like Q005, 70X300A, and XS1A all use a lot of cost to achieve the feeling of that kind of movie. It is because of the absence of the afterglow effect that the cost will be It's so expensive.) The phosphors are even worse, and the spectrum isn't peaceful enough. It's actually just a bright fake red, green, and blue color. The V10's picture has a strange LCD flavor. After the VT50, it was almost the same as the liquid crystal. No plasma has its own taste, especially the vt50's horrible gamma value of γ1.7. There is certainly no natural plasma style. The problem of the backlight I have already said in the first article, simply speaking, now the LCD uses a wled backlight that has a worse spectrum than CCFL, and is not nonsense. The shrinking of the chip has these: 1. The most important algorithm of the TV chip is the algorithm. All the excellent algorithms are lost. The more complex the algorithm, the more multi-chip support is needed, and the cost is higher. It is necessary to know that the cost is reduced to the level of madness. For example, Sony's hx950 compared to hx920, low-rate chip source optimization has been castrated, this cost is only reduced by 2 US dollars, for this 2 US dollars sony still have to shrink; 2, memc chip from the original plug analog frame shrink to insert copy The frame was further reduced to insert the black frame, and then the propaganda evolved from 100hz to 800, and the people who did not know the truth thought that the LCD dynamics had made great progress; 3. Nowadays, there are fewer and fewer matches and adjustments. (Strictly speaking, every television needs Tune-in, because each batch of panels is not exactly the same), in fact, for TV picture quality, tuning is much more important than the progress of the parameters! Pioneer had always insisted on artificial adjustment. Even sony's original machine was engineered to lead the training even at the low end. Now except for the flagship first machine shop worker who uses computer trimming, the rest are bus assembly machines. In other respects, sometimes the shrinking of the manufacturers is really a thing that makes people cry and laughter. They always feel that even the cost of these goods must be saved. Come and come, we continue to take pro (ke) love (lian) sony as an example. (Sony: Why do you say me every time?! Landlord: Who told me that I love you the most and I know you best? Behind it there is a useless but power-up power switch. Let's take a look at the 2012 flagship 55hx950 remote control, the luminous is gone, the keystrokes are less, and the hand feels like it is also poor, and the power switch on the back to improve the forcing grid is certainly gone. Does it look a lot of shiver? Of course, one generation is not absolute as one generation. For example, in 11 years, lg's products are not as good as 12 years, and sometimes the replacement of some models may be better. Such as Sony 14 years of new products, according to insiders (old eight) revealed that w950b although the dynamic and backlight than the shrinking w950a but because the brightness has improved, so the actual perception is slightly better than w950a (the shortest board of the piece of wood was added, but I There is a strong suspicion that life is reduced.) Of course, this is still an irresponsible remark. At the time when we wait for the full distribution of goods, my judgment may change. However, unless the industry has breakthrough technology applications (such as oled civilians), the general trend is surely to shrink shrink and shrink. Here I would like to remind everyone that vendors and evaluation websites always say that new products are the strongest quality on history (屎 , , ,). The company is excusable for doing so. After all, if he talks about my new price, though it's down, but the quality is actually not as good as it was. Then nobody would buy him a TV. Right, honest or kind companies never live well. of. Saying that evaluation agencies do not fly, it may not be acceptable to everyone, especially foreign institutions such as cnet. Yes, I definitely say that most of the evaluation agencies are not reliable, and the more famous they are, the less able they are to believe. The domestic institutions may be random evaluations or even data frauds. In foreign organizations such as cnet, data fraud may not be common, but they are not honest. They will not only selectively tell you test data, but also test methods are optional. It is bought by the manufacturer. Say a recent example, Samsung (sony cows inside, finally did not take my knife Four, random comments - grant people fishing helplessness In fact, I have always avoided recommending specific models in my posts. The reason is very simple. I think it's much better to tell people the trend than to directly recommend models. And the TV models are constantly changing every year. I don’t have the energy and I can't watch them one by one. Sometimes I can only judge people who I’m trusting. It’s inevitable that I’ll be subjective and omission. I’m talking about either high-end or old goods. The former is too expensive for everyone, while the latter is worried about it. When you say that you're ignoring Mao, it is recommended that a TV is too expensive to be sprayed. To tell the truth, this Taoist thing depends on the understanding. After the first piece was sent out, many brothers who read my article asked me to find sony, sharp, Panasonic's old inventory or prototype in the physical store, or Try to find ways to buy the favorite machine. And I'm helpless that many reviews said that reading my article is equal to not seeing, so simply talk about specific brand-specific machines. However, because I understand that there are more machines than 13 years ago, and the new products are still not very comprehensive. The rankings are only sharp and sony I am familiar with. I hope everyone will forgive me. (1) sony 13 years of sony all shrink, the so-called wide color gamut is clearly the product of the test, the actual effect can not be compared with the old and wide color gamut machines, and sharpness, etc. are all lower than in 12 years, and the low-end is able to shrink Shrink. The X9000a is also not as good as expected. The edge-lit backlight and 120hz panel destined for the x9000a can only be used as a high-priced digital photo frame. Sony's high-end flat 2D picture quality rankings: 70x300a> 52, 46x300a> 55x4500>>> lx900> hx920> hx950> hx820> hx720 = nx720> hx850 (don't be surprised, the following generation is very normal)> x9000a(2K)> w950, 900> ex650 (12 years The only product of the same generation to commit is> hx750> W800; And the low-end market of sony is very strange, the overall effect of R5xx series is even better than w650. . . . . Note: 1, qualia005 did not count in, color invincible, but the dynamic is not as good as 70x300a; 2, 70x300a is RGBLED backlight, picture quality is better than using CCFL backlight 52, 46x300a. (2)sharp 13 years of sharp continue its brain damage policy, somehow discontinued the good quality x50, x55a series, the new flagship was late until the second half of 13 years, lx850 price and x50a flat, but the quality is only about lx830, lx750 It is the grade of 640, the price of 8 series, UD10a of 4k and Japanese version is more serious than shrinking, dynamic garbage. It is actually 70x55a Weihuo in the previous period of price reduction is very cost-effective, 60lx640 in the 60-inch which can also be cost-effective. Here to talk about, sharp must start from 640, what 5XX, 4XX and 2XX models do not consider, it is better to buy domestic brands. Sharp part of the flat 2D picture quality rankings: Xs1a>65rx1>>52,46rx1>G7>>>lv925>lx710>x50a>ff1a>lx930>lx920>lx830>lx850>lx840>lx750? Lx640; Note: 1. Screens for xs1a and 65rx1 are sharp. Professional screens for sony monitors are decentralized to civilian use (of course the xs1a panel is slightly better), so 65rx1 is better than 52, 46rx1; 2, 750, and 640 Who is hard to say, I personally prefer 640 (3) Panasonic Panasonic's plasma shrinks for 13 years. The s60 series is even worse than the 12-year ut50 series. It seems that the plasma is really dead! The main plasma is still watching the front plasma articles. It is worth mentioning that Matsushita LCD was very cheap for a period of time, 55wt50c ( Panasonic TH-L55WT50C ) dropped to less than 10,000 yuan, very valuable to buy ! Wt60, dt60 is also very general, really like Panasonic LCD can be considered. (4) Korean system LG used to have a bad picture quality, but since I started 11 years ago, I have made great progress. I have always felt that LG is more conscious than Samsung in the domestic market. 12 years lm6600, 6700 are good machines. 13 years of LG under the influence of the domestic shrinking tide, compared with 12 grades in the same grade also shrank, but the relative degree of shrinkage is the smallest, 6200,6600 has always been the main force I recommend, la8800 as a 2k flagship, cost-effective Also very prominent. As for Samsung, the LCD brand I don't like the most may be somewhat blackish. As the king of the world's flat panel, Samsung is well aware of the "preference" of the Chinese market. Samsung is the most severely shrinking model with foreign countries. Samsung's prices are generally cheaper than Sony's in foreign countries, but it is reversed in the country, but es7000 , 8000 picture quality is not like the grade of sony and sharp, plus the ugly octopus base. . . . . Personally do not recommend Samsung's LCD. But Samsung's 60e8000 plasma is a good thing, the quality is not inferior to st50, and the price is much cheaper! It's a pity that 12 years is hard to buy now. In 13 years, Samsung continued its shrinking fantasy trip. After plasma hit Panasonic at a low price, high-end plasma did not enter the domestic market. Both the vertical and horizontal LCD are shrinking, as the 12-year ES series, relatively speaking, 46f7500 can also be, f8000 is also considered more than standard products, like Samsung's friends can consider starting. Well, originally wanted to write the third article about the secrets and black history of some manufacturers, but look at the writing is almost the same, the third article even if the write is just some gossip incident, it does not necessarily give everyone a better help , the second article even if it is finished. My knowledge is shallow and there are many omissions and deficiencies in the article. I hope everyone will forgive me! ! Finally, thanks all the friends who can keep reading this stinking, long article like WLED! ! Network Accessories,Wifi Adapter,Fiber Optic Network Components,Splitter Fiber Optic Cixi Dani Plastic Products Co.,Ltd , https://www.cxdnplastic.com With regard to energy consumption, I don't normally have much to say about people who care about this, and not watching TV is the most energy-efficient and environmentally friendly. As for image quality, the characteristics of plasma and LCD look and feel are not exactly the same. In general, the plasma is softer and more natural, and the liquid crystal is more sharp and transparent. It can only be said that each has its advantages. Of course, I personally feel that the same level of plasma and liquid crystal, plasma is more suitable for watching movies, and to produce a good picture quality is also a lower cost of plasma. What's funny is that in the forums or groups, those I know who use Pioneer plasma, Panasonic PZ series of powder, the attitude of the LCD are basically more objective, and even they themselves have used or hold high-end LCD, but those mouths Has been hanging on the "plasma picture quality is better than LCD, and rotten plasma also seconds to kill the LCD", asked down the basic are the people with low-end plasma, perhaps strength can indeed determine the horizon (do not enter the seat).
Perhaps a lot of people are used to the ipad, iphone relationship, the ppi display device is very concerned, extended to the TV they also think 4k compared to 2k 4 times the resolution, resolution will spike 2k TV. But they all forgot to watch the distance!
2. From a purely clear point of view, 4k must be meaningful to meet three conditions, one is indispensable: a sufficiently large screen (above 60), a close enough distance (60 inches within 1m, 70 inches within 1.5m, 84 inches within 2m, bless about our eyes it), enough of the film source, otherwise there is no obvious advantage compared to 2k clarity. Everyone will take a seat on their own to be able to meet these requirements in their home and mainland film sources within the next three years.
3, the current high price to buy 4k resolution wled TV is very meaningless and very helpless behavior, wled picture quality is far inferior to the previous ccfl, the manufacturers refused to spend the cost and effort to improve the quality of nature (they would rather study oled), Rely on 4k and intelligence to deceive people, one can deceive one. However, if you just need it, there is no way for it to be obvious that 2k TVs will become more and more low-end, and only 4k TVs will have to be bought in the future.
4, all current 4kled watching 2k movies are not as good as 2kwled straight down the end of shrinking machine king 55hx950, let alone the real machine emperor in 2008 w380, x300a on par. Sony's so-called double-strike technology, the idea is very good, but the control of cost considerations chip does not play a big role, but artificially increased sharpness, leading to false and clear pictures, serious digital sense. 
The brand's common panel shrinks, 10bit shrinks to 8bit I have said before; the color effect of the panel (color gamut attenuation) from the original 3% -8% into the current 12% -30% and many more.
) This is the flagship 55hx820 remote control in 2011, with luminous, feel good (like the feel of a mouse button).
Although the shrinking of the goods does not have a big impact on the use of the set-top boxes, especially if everyone now uses them, from a different point of view, you will have to shrink this type of place and tell me how to believe that you are not shrinking elsewhere. ? ! I am not afraid of everyone’s jokes. When I was still inexperienced, I was hesitant between 55hx820 and 55hx850 (the price is almost the same, 820 is also slightly more expensive), because the disguised piece just feels 820 is slightly better and I see the parameter that the 850 is “advancedâ€. Finally, because of the better appearance, the more beautiful remote control, and the heavier weight, the reason why it was "an amateur" was to choose 820 instead of 850. The result turned out to be right. In fact, the point I want to make is that picking the TV with remote control and weight is sometimes more reliable than looking at the parameters. . .
) The F8000 once sent the machine to CENT and accidentally sent the market machine. The result was measured by the CENT blue level overflow and the green level was extremely low. Later, Samsung immediately gave the money to buy CENT and said it was a bad machine. In fact, it is a market machine. CENT had been measured and released, and the results were retested and republished. The results were criticized as the most shameless evaluation agency. Also, due to the limitations of the test method, many TVs with high running points are not as effective as low-speed machines. For example, dynamic tests are very subjective and difficult to test. The actual performance of the Samsung F6300 is not as good as that of the Samsung F6300. R550A, but the dynamic resolution running points is 1.6 times that of R550A.
