As a coffin living in the Imperial City, I was lucky to have made a local friend. When I first came to the Royal Park, he was very generous to allow me to live in his home - on the balcony. This stay is three years. Today, the local tyrant has moved to his new home. In order to repay the original accommodation, I have unquestionably provoked the task of selecting a satisfied TV for her. (Oh, why did you ask me if I bought one for local tyrants? For the audience, please do not insult the term "local tyrants.")
The beginning of the crashThe first thing to choose a suitable TV is to determine the size of the TV. This is actually determined by the actual viewing distance; that is, the size of the living room and the location of the sofa and TV cabinet. After our actual measurement, the distance between the local home TV cabinet and the sofa is - 3.7M! Then we began to become bad gradually.
View distance and TV size
We found that in the map above, the size of the TV we should buy is about 100 inches! All of you, we have made this expression, certainly not because of money! Can poor money call local tyrants? We are so troubled because of the following reasons. First of all, the market does not seem to buy a 100-inch 16:9 TV. Both Samsung and LG's 105-inch TVs are 21:9. (Samsung’s official website has a 110-inch screen, but unfortunately it does not match local tyrants' furniture. And it's too big.) As a TV with the main purpose of watching TV video, today 16:9 TV signals are not yet popular, the 21:9 TV is a two-capital "waste" , as an ideal A tasteful new-age tyrant, my friend will never allow this to happen to him. Then, we wanted to retreat to buy 84-inch TVs. As a result, most of the products in the world were in 2014, and it was difficult to meet the demand of local tyrants for new products. Finally, under my strong persuasion, the local tyrants chose to buy a 79-inch TV for overuse. After waiting for the right TV in the future, they would put the TV in the bedroom.
PS: The best viewing distance mentioned here is based on the fact that when the viewer watches TV, the screen is full of sight. (So ​​the TV is too big to do)
Inconvenient selection processOn a sunny weekend, we took the notebook to the store and tested the four non-domestic brands (LG, X-Star, Dafa, and Sigma) one by one, and finally chose the LG 79UF9500-CA. At that time, the actual test conditions were limited by the conditions. I couldn't present it to everyone in this article, but I will elaborate on the situation at the time.
Destined to miss out of the boxOne day, I suddenly received a phone call from local tyrants: “The TV arrived. Come and wait for you to unpack it!†I left the phone and rushed to the local Tyrant. As a result, what I saw was such a situation.
Packaging
The local tyrants said that because the outer packaging of the television had been damaged, the express delivery required on-site inspection and there was no waiting for me.
TV front
This TV is completely a mirror when it is not turned on.
Rear interface 1
The rear interface is readily available, and all three HDMI interfaces support 4K@60HZ.
Rear interface 2
One of the three USB interfaces provided is USB 3.0.
Unexpected startup interfaceAlthough it is regrettable that I did not unpack my own case, but some of the tests are still small, but I did not expect a boot, LG gave us a surprise. (The TVs in the store are all set up. We did not experience this at that time.)

Interspersed in the set-up process of such a dazzling animation really shows us blood.
PS: The last set of maps is because the set-top box hasn't arrived yet, so you have to give up the settings first.
Basic testThe first thing to do is to do a basic test to see what the basic qualities of this TV screen are.
256 shades of gray
color
red
green
blue
yellow
white
black
After some tests, we unanimously agreed that the basic quality of the TV screen is very good and the basic performance of the TV screen is excellent. Here is particularly worth mentioning is the black, the entire TV screen at first glance seems to shut down in general, no trace of light leakage corner, very satisfactory.
PS: The ripples in the photos are brought by the camera, not the quality of the TV. The human eye had a very good screen condition at the time.
Seeing here, you may want to ask the governor. How did I choose this one from many TV shows? Don't worry about it. Dry goods come immediately. Next, I would like to appreciate my own "exclusive performance test."
Exclusive performance testHow to choose the one you really want from a wide variety of TVs? How to determine the true performance of this TV from dazzling data indicators? Look at my unique recipes - "yellow test" at lower frame rates, "black test under dim scene" and "dynamic picture test under multi-color scenes."
What does this mean? Everyone plays their own promotional videos while watching TV on the market, and they feel that the display effect is very good. As everyone knows, these promotional films are carefully designed, high bit rate, high frame rate. The selected screen is also the best representation of the advantages of your own screen and display chip. Zealer said in a television review that "buying television is buying a screen." I personally think that this is only half correct. In addition to buying TV screens, the video decoding chip of the TV itself is also crucial. A good video decoding chip can make the TV screen clearer, the color reproduction more accurate, and the character movements under motion more consistent. At the same time, the high-definition video that everyone watches at present is mostly downloaded online. The frame rate of such a film source is generally around 24. Individual high-end televisions do not perform satisfactorily at such frame rates.
To sum up, I carefully selected three sources, mainly fighting, moving pictures, the quality is 1080p, 24 frames. In order to test the performance of each TV in the above three scenarios.
Yellow test
Many people want to ask why do yellow tests? In the daily use of television, I found that many televisions performed unsatisfactorily under the yellow scene. Once the scenes are yellow, people’s faces will become “gold-faced paper†(individuals who feel particularly profound in Dafa, individually Basically can not see the machine). The test piece source I selected here is a fight scenario in "Ip Man 2". Interested friends can test their own TVs with individual scenes from the "Tuo Biography". The following picture shows the phone photographing effect, the following picture is the original picture, the following are the same.

I adjusted the TV's display mode to "theater". From the standpoint of personal feelings, the color reproduction is basically accurate, the characters are not yellowish, and the fighting scenes are consistent in action. The effect is satisfactory.
Black test in dim scene
This test mainly measures the display status of black clothes for people in dim situations. This was accidentally discovered by me on TV. One high-end? General television, actually in this scene the character's black clothes are full of red and blue noise (later Dafa also recruited), it is really difficult to accept. The scene I used for the test was a series of clips from the middle of the famous generation of "Guru".

The Master of a Generation
Also in the "theater" mode, LG's black display is very pure and effective.
"Dynamic Picture Test in Multi-color Scenes"
Although the name seems to be tall, it is actually a dynamic picture display in a relatively colorful scene. TVs that cost more than 10,000 yuan are not bad. The test piece I use here is "Avatar."

Here, I switched the mode to "ECO". Personally I feel that this TV has better performance in some of the more brilliant scenes. The "ECO" mode is also recommended for daily TV viewing.
PS: Please forgive me for failing to find the scene shot by the mobile phone.
In short, after some tests, LG and X Star qualified in my three test scenarios. However, I and local tyrants still prefer LG's performance. I feel that X star's black is too dark, and it is slightly too strong compared to other colors. Without LG's natural display, I finally chose this LG 79UF9500-CA.
At lastThe above content is only my personal point of view. It does not represent the performance of major TV companies in practice. If the supervisor approves my test standard for TV, you can try it yourself when you buy the TV. By the way, this TV has a 3D function and it works well. I'm more passive than active. Specific effects I will not elaborate here. Friends with 3D TV, I strongly recommend the following to you.
