Principle one, size buy big buy small!
Recommended according to the Video Association standards:
Living room two meters five, TV selection 75; Living room two meters nine, 85 to have; The living room is three meters three, 98 moved home
Principle two, look for the official genuine, after-sales worry-free!
Whether it is online or offline, whether it is a cat in the east or a shiver, you must look for the official flagship store, you can click into the store certification, there is no "official", "flagship store" words, do not go to the personal store, lack of after-sales protection.
Principle three, screen quality is very important, the larger the color gamut range, the better!
Conditionally choose MiNiLED, the backlight is micron-level; LCD TVs generally enter QLED quantum dots, color gamut high color pure life is long; (At this stage OLED products are not worth buying, of course, not bad money or do not mind burning screen life short of two or three years to change the local tycoon can enter. ）
QD-MiNiLED luminous principle
There are two kinds of color gamut value standards: BT.709 and DCI-P3, and the larger the value under the same standard, the better. For example, 157% and 130% are high color gamut, which is more than 57% of the color of ordinary 100%, and it restores the real beauty seen by the human eye;
Principle four, software partition is not valuable, backlit partition is valuable, soft and hard partitions should be distinguished!
A, backlight partition: represents the number of backlit hardware partitions, which is where the merchant really spends money
The larger this value, the better: a two-thousand-level partition> a thousand-level partition> a hundred-level partition> a ten-level partition
B, the software partition table is the chip's partition processing capacity of the signal screen, generally more than 2000, belongs to the picture quality software, this value does not have much significance. (A and B partitions are completely different concepts, at present, y bad businesses are playing the backlight partition and software partition of the edge ball, deliberately confusing the concept, looking at the backlight partition)
Principle 5: The higher the peak brightness, the better!
Peak brightness refers to the ability of the backlight to display the dynamic range of HDR, and the higher the value, the better: two thousand > thousand > hundred
At present, the peak brightness of ordinary TVs on the market is about 500nit, and the peak brightness of high-end TVs is about 1000nit
The peak brightness of the flagship high-end TV is about 2000nit;
Principle six, watch sports events and play games to choose a 120HZ screen, with VRR + ALLM is better!
Ordinary TV is generally 60HZ, now high-end TV will use 120HZ, because 120HZ to watch movies, watch sports games, etc. do not drag shadows, do not stutter, play games will be smoother; (the current maximum refresh rate of the screen body is 144HZ, some merchants will be 120Hz screen through overclocking technology false publicity 144HZ and 240HZ, but it is not the screen refresh rate, and will sacrifice the clarity of the picture, no sense)
Principle seven, audio selection multi-channel high-power international brand audio!
Well-known brands > branded > unbranded; external = split> built-in;
Channels: The more the better, the greater the power, the better; the greater the bass power, the better.
Principle eight, full screen, metal frame, ultra-thin and better!
The full screen looks more visually comfortable, the metal border heat dissipation is fast, the life is long, stronger than the plastic border.
Principle nine, clarity 4K is good, buy real 4K do not buy fake 4K
True 4K refers to the standard resolution of 3840 x 2160, 8294400 pixels (about 8.3 million pixels), only red, green, blue three colors, false 4K is also called four colors 4K, there are red, green, blue and white four colors, the effective pixels are only 6220800. When purchasing a TV, use the mobile phone camera function to zoom in on the shooting screen to identify.
The RGB on the left is the true 4K and the RGBW on the right is the fake 4K
At present, the domestic market TV is basically 4K is standard. (At present, there are too few 8K program sources, and the difference between 8K and 4K can only be seen within 50cm of the screen.) Therefore, 8K technology is more used in commercial high-precision static display scenarios such as medicine and high-precision drawing. ）
Principle 10: Choose a first-line big brand that has been developing and producing well in the television industry
As shown in the figure below, buy and sell well, self-produced, have their own ability to produce LCD screens. A first-line brand that has been deeply cultivating the TV industry for decades, the product quality is more secure, and the after-sales service will be more reliable.
Attached is the global sales ranking of domestic brand TVs in 2021
Other additions: buy without boot ads!
Many people will be more concerned about this, hoping to find a TV brand that does not start advertising,
At present, there are no brands that start advertising: TCL/Thunderbird, Sony, Samsung, LG, Panasonic, Huawei, OPPO.
There are start-up advertisements for Xiaomi, Hisense, Philips, Sharp, etc.
