OFweek smart home network news in today's complex market environment, do not know anything that can easily be pitted, although we always hold the conscience of the business and easily trust the brand they trust, but in business, no Business is not a traitor, one day is business, and Li is the first. Consumers often get bored because they don't understand, or they buy products whose quality is unaffordable. It's not important to spend a lot of money. What's important is the word "worth".
As an important household appliance and an important part of the living room culture - TV; it takes a lot of attention to make a purchase and pay more attention to the examination; especially for families that have settled instead of renting, a good TV has spent 8 years. 10 years should be no problem, then let yourself "pretend" to understand a lot of know a little common sense, do not be fooled by the salesman to buy, but also let the other party seriously treat you, recommend you really good TV.
So what should pay attention to buying TV? What are the parameters for buying TV?
The TV size is based on the best local viewing distance
There are several important parameters for buying televisions. Sizes are often overlooked, and selection is more arbitrary. Many consumers are simply pursuing large screens, ignoring the size of their home TVs, and not buying the right TV size based on the best viewing distance.
Although it is easier to have a large-screen movie theater, long-term use will result in decreased vision and hurt the eyes. Second, the quality of the TV will also be affected and it will be easily distorted.
LCD TV's best viewing distance = LCD TV screen diagonal x0.0635
For example: For example, a 55-inch LCD TV with a calculated result of 55x0.0635=3.4925 meters and 3.5 meters
It is worth noting that the size of the curved TV can be larger than the best viewing distance when starting, because the curved TV screen is slightly more effective, otherwise it is easy to become a flat TV; individuals are more likely to recommend buying a flat TV.
You can see how to calculate the best television viewing distance? 】
The quality of the TV screen must be better This is the basis
1. Panel type is not the most important finished product is preferred
There are many types of TVs on the market today, such as OLED, LCD, quantum dots, plasma, etc., but there are three types of panel, hard and soft screens, and X super-crystal panel (X super-crystal panel is a patent of Sharp manufacturers. Belong to the soft screen range), but they are all different processes and have no advantages or disadvantages. Most domestic brands prefer hard screens, and foreign big names like soft screens.
The current mainstream panel manufacturers: Samsung, LGD, AUO and other Taiwanese manufacturers, as well as BOE, China Star Optoelectronics and other mainland manufacturers.
Panel levels are divided into: A, B, C three levels.
Therefore, when choosing a panel, the type is not the most important factor. It is better to choose the quality of the mainstream panel manufacturer. For example, the hard screen LG will do well; no matter which branding panel, it is best to choose a panel above class A.
2. Resolution is preferred 4K, it is necessary to clarify the truth
At present, the mainstream TV resolution is undoubtedly 4K (3840×2160), and 1080P and 2K TVs are still on sale. However, from the perspective of trend, the 4K resolution TV is more affordable and forward-looking. 4K is 4 times that of 1080P, twice that of 2K, and TV picture quality is better and more detailed.
With the increasing abundance of 4K resources and the improvement of network quality, 4K will definitely be the mainstream in the future. Moreover, 4K has a very good picture quality, and 8K is already the limit that the human eye can withstand. Even higher, the human eye cannot “see†the difference.
However, if 8K is not a giant screen, it does not make much sense. As an ordinary family, 8K can only worship, plus 8K resources and network speed even more estimates have long long time, or know that there is such a thing is enough.
In a word: The preferred 4K resolution.
3. Select 4K to recognize the authenticity
The 4K TV market is a mixed bag and technical standards have their own rhetoric. But the real 4K TV's physical resolution is set to 3840×2160, with 4K decoder chip to receive 4K resources, and the picture quality is exquisite. However, the cost is naturally high. Therefore, there are fake 4K TVs on the market. Be sure to pay attention when buying.
How to easily identify true and false 4K TV?
1. Discriminating through professional television detection tools, such as [screen master], [screen bad point detection tool], [Lu master], [screen test expert], etc., can be downloaded through Chipper Market.
2. The parameter "4K UHD TV" is a fake 4k.
The "K" of 4K is English "kilo", which is Chinese "thousand", 4K means about 4000 pixels in the horizontal direction, and 3840 pixels is called 4K for convenience. UHD (Ultra-HD) TVs are TVs with 4 more screen resolutions and 4 times more pixels than FHD (Full-HD) TVs. The "4K UHD TVs" merchants are the ones who fool the concept and really There are differences in the quality of 4K TVs and they are not on one level. If the selling price is the price of a real 4K TV, and the essence is "4K UHD TV," it is a fake 4K TV.
3. Pseudo 4K TVs are blurred in color and viewed with a magnifying glass, visible white lines.
4. There are "WRGB" words in the parameters, and it is designated as a cottage 4K (LCD with WRGB technology, with only 6 million pixels).
5.4K resource playback detection, see speed and quality.
When you buy a TV, especially to the mall, you can put 4K test paper and 4K resources on your USB flash drive, play the test under the test when you buy, view the decoding capabilities, and so on.
Configuration parameters depends but do not blindly pursue
Configuration to see the chip & storage, the screen to see the panel, the operation to see the system ... ... Therefore, many businesses pay great attention to the configuration, give you a list of parameters, it looks good high-tech, in fact, is also watching consumers do not understand.
Remember a few points:
1. Mainstream CPU: Mstar, Amlogic, Adreno, the former two are more common.
2. Mainstream GPUs: Qualcomm Adreno series, PowerVR SGX series, ARM Mali series, Vivante GX series, etc. The Mali series is the most common and the Mali 450 MP4 quad-core GPU and above are recommended.
3. The mainstream storage is 2GB of memory + 8GB of flash memory, buy at least 2GB of memory or more smart TV, flash memory at least 8GB and above.
4. Mainstream remote control: infrared remote control, Bluetooth remote control, voice remote control. Remember, Voice Bluetooth Remote Control> Infrared Voice Remote Control> Bluetooth Remote Control> IR Remote Control (in case of technical compliance).
Millet also launched yesterday, "Bluetooth touch voice remote control", before also out of "infrared touch remote control", "touch" function is mainly with their own operating system, is a relatively new remote control, as good or bad Functionally speaking, it is indeed more abundant, and how the actual use is to be determined by the netizens' reputation.
5. The interface must be complete (USB, HDMI, AV, component, network cable, cable TV, etc.), "multiple" and "new" best (mostly more complete and more excellent, "new" is best to meet the latest transmission standards) !
Preferred: HDMI 2.0> HDMI 1.4, USB 3.0> USB 2.0.
6. Response time ≤ 8ms (the degree of smear phenomenon of LCD TV, measured by response time)
Pay attention to TV large-screen game & sports program high-quality playback, the best choice response time ≤ 4ms; pay attention to a simple high refresh rate is meaningless, with the double speed drive technology can help solve the smear problem.
In addition to reducing the response time, high refresh rate + "double speed drive" technology can also help solve the LCD TV smear problem.
7. The decoding capability should be rich and full (basic support for RMVB, MP4, MKV, MPG, MOV and other common formats, support H.265, support HDR, support 4K better!).
The configuration parameters can be used as a reference for purchase, especially those who prefer online shopping, but if you go to the mall to buy in addition to see the parameters, it is best to try it yourself, from the picture playback, 4K video playback, game demo, etc. To test.
Because the accessories and accessories are compatible, the quick operation is a good configuration. If an accessory is high, but it does not fit in with others, it is counterproductive.
Through professional software such as "Lu Master", "Antu rabbit video test", "AnTutu test" and other tests are better, these can be downloaded from the Chipper market into a U disk and brought to the mall to test.
Look at the operating system, preferred Android
The most mainstream operating system: Andriod. Most of the domestic brands have their own operating systems developed on the basis of Android. Third-party applications also support Android systems. The best choice for domestic use is Android, which makes it easy to install other software.
There are also home systems abroad, such as webOS (LG), Tizen (Samsung), and Firefox (Panasonic), but it is easy to install third-party applications incompatible or unable to install.
Operating system preferred Android. As for the cool “artificial intelligence system†like Xiaomi, or the Levi’s EUI system, or the yun os TV system, which is the most talked about, it depends on personal preferences and habits.
Energy saving also considers power saving and environmental protection
Buy TV also pay attention to energy conservation and environmental protection, do not underestimate this point, not only can the security still have a lot of electricity.
Note the following points:
1. Energy labeling: Grades 1, 2, and 3, Level 1 are the most energy-efficient.
2. Different television types have different energy efficiency standards.
3. Standby power should be within 0.5W.
4. After watching energy efficiency, watch how much TV power consumption is in the acceptable range (energy efficiency = energy efficiency of the product = usage of electrical energy; the screen is big and bright, energy consumption is high, but energy efficiency is not necessarily low.).
General condition: 55 inches: Power consumption is between 100W-200W; 42 inches: Power consumption is between 50W-100W.
The above points (energy efficiency rating, operating power consumption, and standby power consumption) must be viewed before the purchase of a TV to see if it is up to standard and not within the scope of their own acceptance.
The preferred price of mainstream brands is in line with economic ability
For the sake of safety and the long-term use of television, it is recommended to buy mainstream brand television. At present, the market is nothing more than a traditional TV brand, such as Changhong, TCL, Skyworth, etc.; Internet TV brands, such as millet, music, micro whale, etc.; foreign big names, such as Samsung, Sony, LG and so on.
Regardless of which brand, it is recommended to purchase these major company brands, and to consider more after-sales service.
What should pay attention to buying TV? What are the parameters for buying TV in 2017? The above is the view of Xiao Bian and I hope to help you!
