Zu's budget for buying a new TV is 4,000! A price that is very difficult to choose, whether the difficulty in the final analysis is poor!
First of all, let's talk about my purchase process.
The new TV cabinet is still customized....
Use demand positioning
1. The living room is 3.3m wide and the viewing distance is approximately 2.8m.
2, the home is using a telecom broadband TV box to watch, the provided video screen is 720p and 1080p.
3, users are mainly parents, only watching TV, do not play games, most fight landlords.
4, the screen should be large 55 inch +
5, surface! (The surface visual effect is not necessarily good, but the visual experience when watching is very comfortable)
6, the viewing effect is better, not dazzling, image optimization should be in place
7, the use of time planning 5 to 6 years, the quality must pass, the system must be reliable!
At that time, picking up one round after another, there were several alternative products (they later went to the Suning physical store to see a circle and were both PASSed):
#CCTV said Hisense is the first domestic sales! TCL said that it is the third largest sales volume in the world! Unbelievable!!!#
1. Konka Konka’s 29-inch big butt TV set, which had been used in the home for 14 years, is believed to be Konka’s brand.
Konka (KONKA) LED55UC2 55-inch surface 4K HDR Dual 64-bit 18-core smart TV 3799 yuan 4K + HDR, get a new experience of color Jingdong direct link View Encyclopedia After I went to Suning's physical store and saw it, I found a bit of a pit. The model on the Internet was different from that of the physical store, but things were the same. I could only look for photos on the TV...
Advantages: configuration is OK, 4K, surface, 55 inch, processor memory is still available!
Disadvantages: the picture processing is not good! The color is not natural, many videos in U disk can not be played, video format support less! Really drunk, this is the most basic function!
2, TCL
TCL D55A930C 55-inch HDR ultra-thin 4K surface 64-bit 30-core smart LCD TV (black) 4599 yuan Jingdong direct link There is nothing to say about the configuration, the price of 4,000 yuan, the domestic machine configuration is not much difference.
The main problem with this TV is that the overall color is problematic and blue! Gray
Domestic brands: Haier, Skyworth, TCL, Changhong, PPTV, Hisense .......etc., etc., have a common feature!
When Suning strolled, it was discovered that the above domestic brands were on their respective sites. All models play the same picture, one model and one color! ! !
The picture that each TV broadcasts has a certain degree of color difference! ! !
Can not be killed by a stick, but it does have this phenomenon.
# I don't quite understand why this is happening! It may be that the processor and the screen are different. The difference between each model is larger and the debugging is not the same.
Fortunately, Hisense, relative to other domestic brands, the difference in color is very small, may be the same family models, the price is the most expensive domestic brands!
However, in the shops of SAMSUNG, sony, and Sharp, it was found that the color difference was very small, or couldn't be seen!
Sony surface is generally very expensive pass! Sharp straight did not have to say, no surface pass!
Finally selected SAMSUNG # TV should not explode #
3, SAMSUNG
Samsung (SAMSUNG) UA55KC20SAJXXZ 55-inch surface full HD smart TV bronze border black 3949 yuan Jingdong direct link 
Samsung (SAMSUNG) UA55K6800AJXXZ 55-inch HD network smart LED LCD TV 3999 yuan listed in 2016, curved design, stylish atmosphere, can provide a wider field of vision and a consistent viewing distance, bringing an immersive surround visual experience. Ultra-HD quality enhancement engine, natural color restoration, automatic depth optimization technology, different contrast enhancements for different areas of the screen, making the image level richer and more outstanding, smart smart operating system, operating more smoothly. Suning e-commerce direct link to encyclopedia Here to emphasize that I bought UA55KC20SAJXXZ
The UA55K6800AJXXZ and UA55KC20SAJXXZ are the same model but with different border colors!
And UA55KC20SAJXXZ line does not sell!
#It's the same good #
Meet all the requirements I put forward above.
It is easy to overlook the fact that some smart TVs are now based on the android system, causing the boot to be as slow as a cell phone!
Watching TV for half an hour before ink, it's almost impossible! is not it!
Everybody must ask clearly when buying, let the salesman demonstrate again.
Sony, Sharp, samsung start the basic seconds. Konka 5 seconds? TCL20 seconds? Hisense basically opens in seconds. Anyway, based on the android system are slow a beat ...
# It seems that some televisions also have an advertisement with a boot! #
Second, the screen size3m viewing distance, personal feeling 55 inches is more appropriate (everyone feels different, it is best to go to the physical store to experience)
Check the appropriate size of the Internet does not fly!
If it is a curved TV, the suitable viewing distance can be closer. In other words, the same distance to watch, you can buy a relatively flat TV larger size curved TV. And not because the TV is too big to feel the screen is incomplete!
Third, the resolutionThe current mainstream resolution is UHD (4K 4096×2160) Full HD (1920×1080) Full HD # is approximately equal to 2K#
Full HD is gradually exiting the market. The major TV brands have hit the 4K banner!
# You will find that all 4K TVs in the store are 4K demo video, and the colors are very gorgeous. This is not only to reflect the clarity of the TV, but also on the one hand because he does not have the 4K resources of ordinary movies! Only a short demo video. Or because 4K movie files are too large to operate, making it inconvenient to play #
4K popular! Why do I choose Full HD (1920×1080) Full HD? The reasons are:
1, cheap! Samsung curved TV, 55K TV 4K more expensive than 2K 1500!
2, now cable TV, major network platforms, major set-top boxes still provide 1080p video source. 4K TV completely play no effect!
Some people say that 4K TV puts 2K video better than 2K TV puts 2K video.....hehehehehehe. Dreaming?
One reason for selling 4K now is that 4K should be fully popularized in the next 5 years or so. There is also to download or buy 4K movies to watch (a 4K movie, and the latest encoding method is about 20G) # Obviously not realistic! #
3, I expect the use of time is 5 years, five years after the popularity of 4K, there will be more mature 4K display technology, then change to a new TV! Today's Samsung SUHD Quantum Dot Matrix TVs are too expensive. Now, the cost-effectiveness of the purchase is extremely low. It is a waste of resources and there are no resources for such a good TV.
To sum up: 4K is a certain extent the seller's gimmick, the visual effect is not as obvious as you imagine! Especially if there are no corresponding resources
When visiting a physical store, you can ask a salesperson to play a regular video and see the effect
Fourth, curved TV VS flat-panel TVFlat plates are generally cheaper, except for Sharp.
There is a sense of surrogate surface, comfortable viewing, can not describe, it is best to go to the physical store to experience it.
Curved TVs involve curvature—(Chapter 3 in Advanced Mathematics) Curvature k=1/R: Curvature = reciprocal of radius of curvature
Here, we must specifically explain: "Curvature" now referred to by TV manufacturers refers to the "curvature radius" of the mathematical definition.
# Plain, according to the definition of television manufacturers, the smaller the curvature the more curved #
Now the common radius of curvature is related to the size of the screen. It can be imagined that the unit behind is mm (millimeter)
In other words, the appropriate viewing distances are 3.6m, 4m, and 4.2m, respectively!
The size of the curvature is related to the size of the screen. For example, a 55-inch TV has only 4000 and 4200.
Here to add: 4K screen is generally much brighter than 2K screen! The corresponding difference in power consumption is also great!
The UA55KC20SAJXXZ consumes 105W, while the same 55-inch 4K version consumes 175W!
The same screen size, 4K and 2K power difference of more than 1/3!
Six, hardware configurationMost domestic machines like to use 20~30 cores as a gimmick! But actually dividing the CPU and GPU is actually a standard quad-core! Basic is nonsense
Compared to me, I still like millet and sell it as a big tablet. What configuration is straightforward, but it is even more rare!
SAMSUNG configuration - residue! Just watching TV, don't think about playing games
VII. System#The hardware should make sense with the system
Domestic brands usually use Android-based systems
Advantages: The application is very rich, many features, and entertainment is very strong!
Disadvantages: system instability, with a larger relationship with the configuration, it may be as dull as two years after the phone!
SAMSUNG is pure home system software, not based on android, belongs to the system developed specifically for television
Advantages: Basic functions are all necessary. Stability, it should not appear to be dull in two years.
Disadvantages: Poor applica- tions are all Samsung's closed source software, and their number is scarce.
Eight, after salesSamsung's after-sales service is still good, there are installation costs do not forget! Some wall hangings are expensive!
Nine, other insignificant parameters1. HDR (High Dynamic Lighting Rendering) has been a big buying point for TV manufacturers for the past two years. HDR can be simply understood as a video/picture format. HDR video is 4 to 5 times larger than normal video at the same resolution. In other words, a 4K HDR movie has to be about 50G. Did not see at all. And you can't find resources.
The first half of the picture is composed of the following three photos with different exposures, of course, the volume is doubled!
and! Almost no new TV now does not support HDR! It can be said that it is no longer a selling point
2, 3D technology, you need to bring glasses, the same resources are less. The price is very beautiful!
Whether it is a polarization technology like a cinema or a technology that divides the picture left and right, it requires wearing glasses and requires corresponding resources.
Samsung UA55KC20SAJXXZ evaluation! One, out of the box
The younger brother of transport is very good and very polite
Suning's products are delivered in one unit, that is, delivery and installation are a bunch of people. The cost for installing a 55-inch TV on the base is 90 yuan! If the wall is walled, the fees may vary depending on the material of the wall. At least 200, and more than 500.
The base is particularly simple to install, with a total of 4 screws, and Dad is also at home, so we did not choose Suning to install, saving 90 Da.
However, it is not recommended to install it yourself. After all, what fork is not easy to handle....!
A quick installation guide is included in the manual
There are a lot of pictures in the middle and it is not enough time to shoot ~, after all, delivery of the younger brother is equivalent to the obligation to help, I do not work in the side of the picture is really not respect others.
Put the TV on the sofa, peel off the film, install the base ~!
The base fits together, I just want to screw on the two screws, it's not so safe.....
Four screws!
4 caps to block the four screw holes reserved for the TV hanger
#The whole TV only depends on this one support point, feeling a little hanging, in short, be careful #
Please ignore the decoration style of my family in the last century
Now, the appearance of major brands is basically the same, so there is no need to compare, almost on the line
TV is not the same as a mobile phone. Such a big guy has a lot of processing tolerance.
Bronze border ~ color is not correct ...
Gap on the edge of the fuselage
The TV is thin and wide. The body leans forward slightly. I suspect it is a problem with the pedestal or simply the floor is not flat.
Vents
TV interface
This looks easy!
The interface is fairly complete:
1, two usb interfaces: a 2.0, a connected mobile hard disk HDD
2, three HDMI interfaces: STB set-top box / ARC audio / PC computer
3, network cable interface / fiber: built-in wifi and Bluetooth
4, component input: there is no basic use of HDMI this useless
5, TV cable interface
When you play games, you usually play on the TV.
Come to sister, Zhang Ying!
My sister discovered that Lao Mai was taking pictures and she could not see
There are small rich
# Because Samsung did not specify that the cpu is not a common cpu model used in domestic TVs, it does not know specific performance. If there are too frequent operations, there is Caton but it is acceptable. No wonder APP is so disabled
1, the main interface We are most concerned about the screen effect! !
Now smart TV remote controls are basically the same
Press the "small house" button, the main interface will pop up
# I connected the TV box and inserted a 1.5T hard disk (five disks) #
Set the main interface - all quick settings
"More"
Image mode shortcut settings have 4 options
This system has "expert settings"
Before watching the Changhong 55 inch 4K surface machine in the survey did not have "expert settings"
# But personal feeling as long as the factory debugging is very good, this feature is also not used #
Poor
And I don't feel like I'm using a search application. The total number of applications is more than 20! ! ! #Fooling ghosts #
The most commonly used Chinese TV
Only using songs is not money!
The network is not so good...
a. Your own TV box
Connect with HDMI
Only 9 of 4K sources! No captions yet...
b. External storage device
Basically covered in the format, only one video in my hard disk can not be played #MP4 format does not know why can't play #
c. Samsung smart view
The function is very easy to use, that is, even a little fee, found that the network's time is a bit long, the phone goes out and the screen is off....
advantage:
1, excellent color adjustment and optimization, and professional debugging
2, the system is simple, more suitable for long-term use, will not gradually change the card as the system upgrade
3, high cost performance
Disadvantages:
1, the curved screen viewing angle is low (about 120 degrees), your home sofa can be installed. (A new generation of quantum dot matrix screens, with self-illumination of the display unit, greatly improved brightness and resolution, but it is still expensive)
2. The structure of the base bracket of Samsung TV products is very beautiful, which means it feels a little unsafe and the support point is small.
3, APP simply does not see, less and waste!
There are many different versions of DIN Connectors. The name of each type comes from the number of pins the connector has (3-pin DIN, 4-pin DIN, etc.) Some of these pin numbers come in different configurations, with the pins arranged differently from one configuration to the next.
DIN cable connector 3-pin, 4-pin, 5-pin, 6-pin, 7-pin, 8-pin degree 180, 216, 240, 262, 270
