The demo screen that it plays is also very clear, originally intended to buy a 40-inch or so TV, the results will see the 55-inch large-size TV, the will is not so firm!
If the promoter feels that you are slowly targeting the large-size TV, you will face up and give you the benefits of marketing a large-size TV. For example, large-size TV screens are more realistic, more on-the-spot, stronger in definition, stronger in performance, etc. They may even say that the temptation of a large-sized TV holiday is to drop a few thousand dollars. In short, all kinds of large-size TVs are good. Will enter your mind.
Since your will is not firm, it may lead to wrong decisions. Because the choice of TV size is based on the size of the space.

Only by having a powerful "core" configuration can smart TVs behave more fluently in their applications, have a better experience, and meet the needs of young consumers today. So what kind of standard does the current smart TV achieve in the "core" configuration?
According to the author's understanding, since the birth of smart TV, the "core" configuration has always been the focus of attention. The rapid development of smart TVs in recent years, "core" configuration is also constantly upgraded, from the initial three-core, four-core, six-core, and gradually increased to the current 8-core or even 10-core. The configuration of the core is like a new fulcrum for the TV, which makes it instigate all kinds of new enhancements. Thus, for users who plan to purchase smart TVs, the "core" configuration is worth considering when we purchase.

The operation of all programs in the smart TV is performed in the memory, so the memory performance has a great influence on the smart TV. For consumers to buy smart TVs, memory is also a core piece of hardware worthy of everyone's attention, especially for young users of games, the memory must meet the standards promoted by the manufacturers, otherwise they want to play somatosensory games on smart TVs.

The TV interface is in good condition and the data line is frequently plugged in during the demonstration. Therefore, the interface is the most vulnerable to damage. Such as the pin bent or broken, the interface due to poor oxidized contact or because of frequent hot plugging interface failure. Therefore, when selecting a prototype, be sure to check each interface once and see if the signal input is recognized correctly after connecting the corresponding device and whether the audio and video signals are synchronized.
The functions of the TV are normal. In the demonstration process, various functions will be repeatedly used for demonstration. Some performance will be discounted. The remote controller and OSD buttons are used more often than not. The elasticity may not be maintained well. , The sensitivity of individual keys decreases. Therefore, customers need to carefully and carefully test the various functions of the product during the process of selecting the prototype, operate the remote control, and check the sensitivity of the commonly used keys.
The inventory of TV accessories, although the incomplete packaging of prototypes is an unavoidable thing, but before the payment, we should calculate the number of parts of the official product to see what is already equipped, what is missing, can Can not ask the merchant to complete, it can not be equipped with items where to supplement the purchase of complete, the price is about how much. In these cases, the customer can understand the dealer clearly, and the best condition requires the seller to re-prototype the complete package.
After confirming the after-sales service agreement, many manufacturers will often impose restrictions on the return of prototypes, but the prototypes are also entitled to enjoy the one-year warranty for the entire country's machine and the three-year warranty for major components. In order to reduce the trouble for future use, it is best to clarify the after-sales service in the form of a text agreement with the merchant at the time of purchase.
In the end, the choice of prototypes is largely due to the fact that they are affordable, so in the end the prices should not be vague. Before buying, you must know the actual price of the new machine, so as not to spend less than the new machine to buy back a prototype. The suggestion is to look at the parameters and suggested quotes of the LCD TVs provided by the network, and then go to the store to purchase.
