How to buy LCD TV
1, see the resolution size
Resolution is an important standard for measuring the performance of LCD TVs. The current mainstream resolution parameters are 1366×768 and 1920×1080. The resolution of HD flat-panel TVs in the horizontal and vertical directions is higher than 720 lines. In simple terms, the real high-definition flat-panel TVs must meet the resolution higher than 1366×768.
2, check the response time
The response time is also very important, it will determine whether there will be fuzzy and smearing phenomenon when displaying high-speed dynamic pictures. The experts of the purchasing partner remind everyone that the current mainstream 8ms response time can basically meet the requirements of use. In general, the faster the response time, the less likely LCD TVs will appear to be trailing and afterimages. It is best to see the effect of playing the action movie before you buy it.
Tip: To view the TV picture from multiple angles, for example, to select the right facing screen from the angle, and then offset some angles, and to stand on the horizontal line with the TV screen to see if the picture can be seen; when the machine is inspected, It can also allow promoters to play some fast-paced screens, see if the screen display action is consistent, and whether the screen hangs.
3, brightness, contrast can not just look at the number
In fact, consumers can directly ignore the manufacturer's brightness and contrast parameters, directly based on their own visual experience, the method is at a distance of 5 meters away, view the screen display brightness and contrast, pay attention to the details of the performance of some dark scenes, do more Comparison of several products.
4, pay attention to the display size is complete
At present, the mainstream size of LCD TVs are basically 27-inch, 32-inch, and 37-inch. These have been able to meet the viewing needs of the living room and bedroom, but here we must remind that it is best to buy a brand with a relatively rich product line, the reason is very simple The products of these brands basically all use the “sixth generation†LCD panel production line. Only the products that are released from these production lines can meet the requirements of high-definition digital television. At present, most of the mainstream brand product sizes include the specifications of 42, 37, 32, and 27 inches.
5, HDMI interface
The HDMI interface is a digital interface that can simultaneously transmit audio and video signals. It not only simplifies the connection, reduces the burden on the connection, but also provides a large bandwidth for digital signal transmission. Emphasizing the importance of this interface is mainly due to the fact that new and future players, computers, home theaters and other devices will actively adopt this interface, and the use of this interface to connect with these devices will undoubtedly achieve the best results. .
6, bad point
Be sure to carefully observe whether there are bright and dark spots on the screen before buying. You can search for dark spots on a blank screen, and look for bright spots when you are on a black screen. The experts of your purchase partner tell you a trick to identify bad points: when you are looking for dark spots on the full green screen, find bright spots when you have a full blue screen. Once there are bright spots Or dark spots are very easy to see. In addition, it is best to negotiate an agreement on the bad point with the merchant before writing the contract.
Tip: Test a few more monochrome screens at the time of purchase and watch out for any unusual color pixels. The easiest way is to make the screen black and see if there are bright spots in a piece of pure black. Then make the screen white and see if there are black spots. Finally, change to red, green, and blue to check the integrity of the color point. If you find that there are too many dead pixels in the inspection process, it is best not to buy.
7, sound quality
Various manufacturers have their own selling points in this area, what surround three-dimensional surround sound, SRS virtual surround sound, BBE stereo sound effects, crossover speakers, DDAS digital dynamic sound valley, a variety of audio decoding chip and engine, can be described as a pattern Many. However, these items do not bring practical significance to ordinary consumers except for some professionals and music enthusiasts. No matter how lively the hype, the actual effect is basically the same. Therefore, consumers should make decisions when selecting, and listening to the sound quality is the key.
8, remote control
The remote controller is the most easily overlooked when picking. Good remote control is resilient. Good remote controllers start to give people a very real feeling, and poor remote control is usually very light, the reason is that in addition to the components inside the work is real, the shell is used in different materials. The closeness of the upper and lower shells of the remote control is tight, the good combination is very tight, and the poor combination is loose. A good button can be pressed with just the right amount of force, good elasticity, and a strong rebound. In the end, you can also tap and hear the sound. The poor remote control sounds like it is empty, and a good remote control sounds like it is solid because it is working.
9, design
The selection of LCD TVs also needs to focus on whether humanized design is in tune with their own usage needs. For example, the integration of the appearance of flat-panel TVs and home design has received unprecedented attention and the appearance cannot be ignored. Another example is the use of active backlight adjustment, wireless headset reception and other functions will affect the use of experience. Especially the design of the speakers is particularly important, because listening will not affect the effect of watching. Compared with the traditional design of traditional two-side upright speakers, horizontal is gradually becoming popular.
As the current 16:9 LCD screen is already the mainstream of LCD development, which makes the LCD TV in the vertical extension of the length of the LCD TV body, horizontal LCD TV speaker design makes the 16:9 LCD TV screen overall layout more coordinated. Another horizontal speaker design is conducive to the performance of vocal dialogue, people are more immersive, and its role is similar to the center speaker in the surround sound system. In a surround sound system, 70% of the sound comes from the center speaker.
10, after-sales wall-mounted TV requires professional installation
Select after-sales service, mainly to see the warranty period of the LCD screen. Under normal circumstances, manufacturers provide one-year free warranty and other parts free warranty for three years. Need to use the wall-mounted LCD TV, it is recommended that manufacturers require professional installation. According to this year's new national standard for flat panel TV installation services, large manufacturers should be able to provide on-site installation services.
11, the viewing angle should be large
When viewing a liquid crystal television, there is also a problem of a viewing angle, that is, when a person's eyes and a viewing angle of a display screen are larger than a certain angle, the screen display may be unclear and the reflection degree may be too large to make the screen clear. Therefore, the larger the viewing angle, the more favorable it is to view the television picture at various angles. At present, the recognized viewing angle in the industry is 160 degrees to 170 degrees up and down and left and right. At this angle, the viewing needs of most occasions can be guaranteed. At present, the viewing angle of most brands is around 170, and the viewing angle of the TCL TV series is even close to 180 degrees.
LCD TV purchase considerations
1, soft screen and hard screen tricks
Watching TV in the store, you can often hear promoters mention the difference between hard screen and soft screen when introducing the machine. After the explanation of the promoters, they actually say that the fingers have left behind the traces on the LCD screen. If you can see a clear trace after gently sliding it, it means that it is a soft screen, hard screen is difficult to slide out of the traces. So when you like a salesman to bargain, he will tell you that this is a hard screen, and ordinary soft screen is not the same, the price of a soft screen machine can, and then casually refers to a worn model.
In fact, the soft screen and the hard screen are not related to the quality of the LCD panel at all. It is said that the high screen quality of the hard screen is unpredictable because the relationship between the hard screen and the soft screen is a feature of the two types of panels. For example, the comet's S-PVA panel is a soft-screen design, characterized by true colors and high contrast. LPL's IPS panel is a hard-screen design, featuring bright colors, large viewing angles, and fast response. The above two types of panels all belong to the high-end panel. Can you say that I-Star's S-PVA is not as good as IPS? Therefore, there is no need to spend too much money on such promoters.
2, the type of panel is also tricky
LCD TV 70% of the cost comes from the LCD panel, promoters often make use of this to make a fuss, such as which products use the Sharp screen, Hao Xing screen and the like, in fact, they do not know what is the screen. For consumers, it is easy to be deceived. In fact, this is not to say that the Comet screen is certainly good, nor is it that the screen in Taiwan is certainly not good. The key is to rely on the display technology and the DAC panel driver. A good picture quality is not only created by the panel.
3, pay attention to the exchange speed This represents the performance of the TV
In fact, when switching signals and switching channels, many televisions have a short black screen phenomenon. This actually has a direct relationship with the TV circuit design and the main control chip. Sometimes, the black screen time is very short, it is also 1,2 seconds, but some TVs are very long, even about 5 seconds, if only for a channel is OK, if you switch between multiple channels, I believe Not many people can stand it.
It is advisable to try to switch several sets of signal sources when buying a TV. At the same time, the promoters are required to access the wired signal, watch it in person, and switch channels to experience it. If you can choose within the range that you can accept, you must not buy it.
4. Workmanship determines everything
Good workmanship and quality will surely bring good word-of-mouth, and only paying attention to selling products will be counterproductive. It is possible that you will win the market in a short period of time, but over time, consumers will not buy it again, rough workmanship, quality will not work, and relying on cheap is not feasible. The rough body represents rough internal workmanship.
5, wall mount quality is good
Now when buying LCD TVs, major TV brands are only equipped with pedestals and not equipped with pylon. Users who want to carry pylon can only buy pylon by selling TV salesmen or after-sales installers, but they are on the market to make profits. Just find a cheap pylinder and hang up your TV.
Do you not know whether or not you have ever thought about a very important issue? What materials are they used to support the racks? Are there any nominal weights on the packaging or in the instructions and the addresses and contact information of the manufacturers? Are there any products? Brand and GS/CE/UL/ROSH and other related safety and environmental certifications? Therefore, the purchase of LCD TVs or friends to be purchased must pay attention to the above details when picking up LCD TV racks.
