What to pay attention to buy a smart TV? Don't let the low prices go blind

The May Day International Labor Day is coming soon. Some people choose to go out for fun on the three-day holiday. Some people choose to shop. After all, during the May Day period, whether it is a store or an electricity supplier, there will be enough amazing promotions. I believe many of my friends are already preparing to update their home television during May 1st. In order not to buy you regret, I will give you several suggestions here today. I hope to help your purchase of TV.

One: According to the size of the living room

Recently, the concept of large-screen smart TVs has been hotter by manufacturers, and its prices have dropped further. Many 55-inch smart TV basic cabbage prices have caused many people to bear to purchase. But to be honest, buying TV must be based on your own use. If it is a small-sized living room or bedroom, then there is no need to buy a large-size TV product.

If the television screen is too large and the viewing distance is near, it will be very tired for the viewer. I believe that readers who have had a movie sitting in front of a movie theater will certainly experience it. Therefore, for the TV's size selection, it is not big enough but suitable for the best.

So what size of TV should you choose? Here is a simple calculation formula: LCD TV's best viewing distance = LCD TV screen diagonal x 0.0635. For example, for a 55-inch LCD TV, the calculated result is 55x0.0635=3.4925 meters and 3.5 meters. Then for a 55-inch TV user, the distance of 3.5 meters is the best viewing distance. Of course, we can also calculate the size of the TV that is suitable for the size of the TV. For example, if the viewing distance is 3 meters, then use 3 ÷ 0.0635 = 47.244 ≈ 47 inches, then you can buy 47-inch TV is most suitable. Of course, everyone does not need to be too strict in terms of size. For example, if the distance is about 2.6 meters, then 40-inch or 42-inch TVs can be selected.

Second, the hardware configuration do not be fooled!

Since it comes to smart TVs, then the smart hardware configuration of the TV cannot be ignored. In some descriptions of smart TVs, we often see descriptions of the number of processor cores that are counter-intuitive, such as 14-core, 18-core, 20-core, etc. In fact, this is an additive algorithm with our smartphones. Generally speaking, the quad-core, eight-core is not the same, it is not more superior performance. Therefore, we must not blindly think that the TV hardware is powerful enough to be purchased because of the high number of cores.

Third, 4K or Full HD?

The concept of 4K TV started in 2015 and began to rise in 2015. Currently, there are a large number of 4K TV products on the market. So we choose 4K TV or 1080P Full HD TV? After all, 4K TVs are a little more expensive because of the screen cost. Is it worth the extra money spent on buying a 4K TV?

First of all, we are concerned that 4K content is currently not rich in domestic 4K content. Although several video sites have been actively deployed, it is difficult to achieve real results in less than a year or two. At the same time, even if 4K video content is rich in resources, there should not be too many free resources because of copyright fees, production costs, and other 4K content. This means that we need to say the next question of consumption, buying a 4K TV is bound to look at 4K content, otherwise it is a waste. However, if you want to watch 4K content, most of them still need to be charged, so whether it will be paid for 4K content again, I think this point will be the focus of your purchase of smart TV.

Another point is the network broadband situation, 4K video network transmission is bound to be greater, if the home network bandwidth is not enough, the online 4K video content looks very likely to be stuck. Therefore, whether to buy 4K TV must be combined with their actual situation to purchase. Do not be blindly attracted by the 4K TV's picture quality. After all, the current definition of domestic live TV signals is basically 720P. The channels with 1080P resolution are very rare.

Fourth, third-party application extensions!

For smart TVs, there are currently licensed licensee video resources, but this is not enough for most users, but also need to install some of the mainstream television aggregation applications in order to better meet the viewing needs. Therefore, when purchasing a smart TV, it is best to ask if this TV supports the installation of third-party applications.

According to the author's understanding, some Samsung smart TVs and some LG smart TVs do not support the installation of the current mainstream third-party television applications because of their own system. It seems that they can only install applications that come with the TV application store. Of course, in addition to that, there are certainly other smart TV products that also have corresponding limitations. Therefore, if you want to use TVs to perform more functions or content extensions, it's best to ask in advance about customer service or shopping guide TVs. Does it support third-party application extensions like this?
