With the arrival of Double Eleven in 2022, various strategies or lists are emerging one after another. Among them, the most common one is the "eight-sentence formula for choosing TV shopping". After watching it, it is really "tied up" after watching it. When you think you have made money, in fact, an insider shook his head and clicked to exit. The editor thinks it is really necessary to help organize a full guide for those who need to buy it.
As we all know, TV has many parameters. Only by figuring out the relevant concepts can we effectively avoid being deceived. This article starts with the most basic popular science, and explains the common parameters and issues involved in TV purchasing at one time.
In between, first divide the circulating "eight sentences" into three parts:
, picture quality: RGB real 4K, screen QLED, motion compensation ;
, configuration: memory, CPU, HDMI interface;
, others: boot advertisement, anti-blue light. Classifying
in this way will reveal that the above parameters are actually not comprehensive, and even the most basic picture quality cannot be explained thoroughly. We are not in a hurry. Let’s discuss and analyze in detail according to these three categories.
1. First of all: picture quality, the top priority
TV picture quality can be divided into two major aspects: clarity and fluency . There are only 3 parameters in this regard in "Eight Sentences Meditations", which is far from enough.
, among which, the clarity of the image quality is mainly affected by the screen material . This is because different screen materials have different performances in terms of brightness, contrast, color gamut, etc. Common screens include LED, QLED and Mini LED.
Everything has two sides, the advantages and disadvantages of the three screens are listed below, which is clear at a glance.
From this, it can be seen that From the perspective of comprehensive performance, the Mini LED screen is a little better. This is mainly due to the Mini LED technology that refines the backlight beads of traditional LED TVs to a size of about 200 um, which is about the diameter of a hair. In this way, more number of lamp beads can be placed under the same size to achieve more finer light control. Finally, it makes the picture more layered, the details are clearer, and the colors are richer.
So, when the editor saw that the blogger did not explain anything, directly compiled "QLED" into the "Eight Sentences Mentals", he felt that he was not responsible enough to his fans . Because of QLED TVs with partitions, the number of partitions has a great impact on the quality of the image. For the screen, you also need to choose according to your own situation.
In response to this situation, the editor has recommended TCL98Q10G to fans who left messages. At that time, his budget was around 20,000 yuan, which was almost the same as the initial price of this new product. The main reason for recommending this model is that this is a TV supported by Mini LED technology. It has 672 gold partitions, supports 1,600 nits of peak brightness, and is very high-definition and bright, with a picture quality that is not inferior to QLED TVs. The most important thing is that it will have a longer lifespan and a higher quality and price ratio, which makes up for the shortcomings of QLED TVs and retains the advantages of good display effects of QLED TVs.
Thanks to 672 golden partitions, TCL98Q10G can easily present more details on the screen. At the same time, it also supports 16 million:1 contrast ratio, 95% high color gamut, and true 4k resolution, which is the best in the picture quality performance.
. In addition to the screen, the resolution of also plays an important role in image quality. needs to be noted by the distinction between true and false 4k. Fake 4k refers to the original resolution being less than 4k and stretching to 4k through the late algorithm. The most obvious feature of this opportunistic deceptive behavior is that it lacks details, and there may be excessive sharpening or excessive softening.How to tell
? Take out your phone, turn on camera mode, and enlarge the phone screen until you can see small pixels. If there are only three colors, red, green and blue, it is true 4K, otherwise it is fake. Or remember that only H.265 is a coding format designed for 4K.
Summary: The performance of screens (such as LEDs, QLEDs and Mini LEDs) in terms of brightness, contrast, color gamut, etc. affects the clarity of picture quality, and the resolution affects the clarity of picture quality through the number of pixels. (Note that true or false 4k).
The last point that affects the picture quality is the fluency of .
The main parameter that affects the picture fluency is the refresh rate. refresh rate refers to the number of times the screen is refreshed in one second. Because the screen is constantly refreshing, it can present a continuous dynamic picture. This means that the higher the refresh rate, that is, the more refreshed it in one second, the more stable and clear the image will be, and the more smooth the visual feeling will be.
At present, high-brush products such as 240Hz, 144Hz, and 120Hz have appeared in the TV industry. But at this stage, the larger the value, the better. There are two main reasons:
①The content that can be displayed is lacking, and neither video nor games, there is no actual use scenario of 240Hz;
②The 240Hz solution adopted by major manufacturers at this stage is mostly at the cost of losing image quality, with the same principle as the above fake 4k.
Therefore, at this stage, k120Hz has become the most mature solution and is also the standard for smart TVs. Of course, there are also brand manufacturers that are spending money and thoughts to truly increase the refresh rate. For example, the TCLT7G model that sports fans and gamers are very passionate about nowadays is a full channel of 4K144Hz. Really done: high definition, high brushing, high highlighting.
Let’s talk about sports compensation. In fact, sports compensation is commonly found in TV products above 3,000 yuan. The purpose is to assist in refresh rate and make the visual feel smoother . In other words, if you follow the "eight-sentence formula" to find sports compensation when purchasing low-end products, it is like picking a phoenix in the flock of chickens, which is very difficult.
Summary: Due to technology and content sources, 4k120Hz is the best choice for mid-to-high-end products at this stage. Of course, there are also real high-brush TVs similar to TCLT7G that will achieve technology to 144Hz. Secondly, it is best to install sports compensation for TVs above 3,000 yuan to make the picture smoother.
or above is all the content that affects the clarity and fluency of the picture quality. If you want to pursue high picture quality, first, the choice of screen type is very important, second, high resolution, and third, strong performance to ensure refresh rate. Only by meeting these three conditions can we achieve the effects of high clarity and smooth picture quality, thereby achieving the so-called high picture quality. Other image quality parameters are all icing on the cake. When purchasing a TV, just buy it as needed.
is not easy, I finally finished talking about it.
2. Configuration + other
The configuration and other two sections mentioned in the "Eight Sentences of Mentals" are not very controversial and relatively complete. What needs to be added to is to choose a TV with good sound quality.
So, below will briefly list the issues you need to pay attention to when purchasing.
Conclusion
Finally, I want to say that TV belongs to home appliances and has a very long usage cycle. Therefore, before purchasing on Double Eleven, you must make sufficient strategies before you can buy it, otherwise it is likely that you will be very upset when you see the TV in the next 5-10 years.
is OK, I hope the above guide can help everyone. Finally, thank you for seeing this. If it is helpful to you, please like it and leave! Follow me to learn more tips for purchasing household appliances.
