What are the problems that need to be paid attention to when buying an LCD TV? Ask for a high finger

The most important thing is the display.

I'm based on my own experience of use.,I hope it's useful to you.,I think the first is the second function.,Because even if you buy a lot of functions but it costs a lot of money.,Mine is bought only half a year after selling online dropped by more than a thousand.,There's clarity.,You can't just look at their demo screens.,Those ** can't be measured.,The best way is to let them connect to the computer as a monitor.,See how smooth it is and how clear it is, And what it supports is how large the capacity of the USB disk and mobile hard disk is (the format is not important, after the format comes, I can convert the format of lossless data on the computer, mine only supports 480GB), and what is the highest resolution it supports, the higher the clearer, as for its hard screen and soft screen, I personally don't think it has much effect, because you need to change it for a few years, and the hard screen is much higher than the soft screen**Oh, and what type of interface does it support, you must see it clearly, And then there's its after-sales, if you have bought something online, you can buy it online, it's much cheaper! And the information parameters on the Internet are definitely much more detailed and thorough than what the salesman said! This is my personal experience, I hope it will help you!

1. Look at the after-sales service guarantee. Although the screen of an LCD TV has a long shelf life, if it is accidentally damaged, it will become very troublesome to repair. It is understood that most manufacturers will now provide a warranty period ranging from one to three years, and even some manufacturers will provide free door-to-door service or maintenance reduction and exemption benefits during the warranty period.

Therefore, when you buy an LCD TV, you have to look at the after-sales quality of the manufacturer.

2. Determine dead pixels. The most common problem in LCD TV screens is that there are "dead pixels". Although today's salespeople say that their products will not be damaged, the criteria for judging each manufacturer are different.

Therefore,When buying an LCD TV,Be sure to ask how many points or more are bad points,So as not to damage your interests。

3. The selection of screen stools should not be too large. Normally, the display screen of a traditional TV is seventeen inches, but about one inch around it cannot be displayed, so the actual screen size is only more than fifteen inches. Therefore, when consumers buy LCD TVs, they must choose the right size according to the size of the living room, so as not to cause the screen to be too large and cause a sense of oppression.

Kuanlu Brigade. 4. Selection of brightness. As we all know, brightness refers to the brightness of the picture, and the unit is nits or cd m2. If the brightness is too low, the screen will be blurry.

It should be noted that whether the brightness is uniform or not is closely related to the configuration of the reflector and the backlight, so as long as the picture is switched to the state of black screen, you can see whether the brightness is uniform.

Things to keep in mind when buying an LCD TV are as follows:

Make a budget first, what do you want, and how much you want to configure.

When buying an LCD TV, we must first know what size of LCD TV we need to buy, because the size of the LCD TV is closely related to the size of our room.

The resolution of the LCD TV is an important criterion to measure the performance of the LCD TV.

Finally, consider the after-sales of the product, of course, it is also the key to our consideration,If the after-sales of LCD TV is not good,No matter how good the product quality is, it's useless,Who to repair if it's broken。

When you understand its after-sales service, you can look at it from the screen warranty period of LCD TV,The warranty period of the whole machine provided by the general manufacturer is one year,Other components are three years,Large manufacturers should also be able to provide door-to-door installation services。

Liquid crystal display, abbreviated as LCD, is a substance between solid and liquid states, organic compounds with regular molecular arrangement, heated to a transparent liquid state, and cooled to appear crystalline particles in a turbid solid state.

To be honest, if you say it so professionally, others can't understand it, maybe that's what the experts say. In my opinion, the main thing to choose the screen is to look at the picture, such as whether there are spots, bright spots, impurities, color casts, etc., and you can choose the visibility!
