The most critical purchase suggestions
TV is not like other large appliances, and there is a big gap in the logic of purchase. For home appliances such as washing machines, air conditioners, and refrigerators, there is actually not much difference between ten years ago and now. However, the TV technology more than ten years ago is very different from that of today. TV has changed from hardware being king to a home appliance that takes both hardware and software into consideration.
1. Don't be superstitious about parameter configuration, which can only be used as a reference factor. In addition to parameters, adjustment is also very important. For many TVs, the parameter configuration data looks very good, but in fact, the card is still stuck. This involves the problem of hardware adjustment. In the past, many electronic products, such as mobile phones and computers, had very good parameters, but the actual application experience had great problems, and the system had defects or something. Therefore, in addition to high configuration, it must also be adjusted well.
2. Seeing is believing. Whether a TV is good or not, in addition to looking at the parameters, it is more about going directly to the physical store to try the effect. TV is different from other home appliances. Refrigerators and air conditioners may not be able to test the difference in physical stores, but the effect of TV is clear at a glance. You must go to the physical store to try the effect. But you don't have to buy it in a physical store, just buy it where it's cheaper.
3. Don't trust the online reviews, netizen recommendations, and offline shopping guide recommendations, as some of them are even deceptive.
4. The hardware of several leading TV companies is almost the same, and none of them is particularly outstanding, but there is still a gap between the brands in terms of software applications. You will know it if you try it in a physical store.
Functions and parameters:
Core: size, CPU, memory, panel, screen material, 4K, color gamut, color depth
1. Panel: divided into IPS panel and VA panel. IPS will leak light, and VA will respond slowly. Curved screens basically use VA panels. The way to distinguish is that a ripple bar will appear when you press the screen with your finger. Both have their advantages. If there is no special need, both can be used. Just choose according to your needs.
2. Screen material: LCD, OLED, QLED. I won't explain it here, but each has its own advantages and disadvantages.
3. Energy efficiency level: starting from the most economical, there are level one, level two, level three, and so on. Level one will be more expensive, but the electricity bill saved is definitely worthwhile. If you can choose level one, choose level one.
4. 4K and pseudo 4K: Fake 4K is not supported for playback with H.265 encoding. Fake 4K is included in the parameters with RGBW, 4 colors, etc. True 4K only displays red, green and blue.
5. Color gamut: Greater than 72% NTSC or greater than 100% BT.709 is a wide color gamut.
6. Color depth: basically 8-bit, the ultra-high-definition Blu-ray standard is 10-bit
7. CPU: A73 quad-core > A72 dual-core / A53 quad-core,
8. Memory: 2G, 4G
9. Storage space: 8-64G
10. Interface and size
About the choice of online and offline purchases
1. Many models of home appliances are separated online and offline, called exclusive models, and each major online platform also has its own exclusive models, which is not easy to compare prices, but TVs are basically not divided into online and offline.
2. If you choose a model that is not an exclusive model, you can compare prices on multiple platforms and in physical stores. Don't be lazy if you want to save money.
3. If you know people in the home appliance industry, you can buy from them, but remember to compare prices yourself and don't be cheated. In addition, store managers like JD.com and Suning will place orders at internal channel prices. The same model will be much cheaper than online and offline, and the cost performance is quite high.
