When buying a TV, the first choice is generally to buy a TV for the living room. It will look more dignified when there are guests at home, and it is also suitable to install a TV in a room for the elderly. It is recommended to install a projector in your own room, so that the world between two people will be more beautiful. ! Therefore, as for the size of the TV, I personally feel that there is no need to overly calculate how to choose. There is no harm in choosing a larger size to put in the living room. requires a minimum of 55-inch TV.
However, it is true that if the distance is too short, it will be uncomfortable for the eyes. Just like when we are in a movie theater, we will not choose the first three rows either because we have no place or as a last resort. So I made the following chart for you to reference between distances and sizes!
However, if the opening distance is really short, you can choose a 45-inch TV.
2: Choice of TV type:
Currently, TV types are mainly divided into two types of TVs; one is the more traditional LCD TV , and the other is OLED TV with future development trends.
LCD TV, the technology has been very mature now. Because the price is relatively cheap, it is the mainstream TV in the market now. If you don’t have a big budget, you should choose LCD TV (Hisense ’s ULED is also an LCD in nature); OLED For better picture quality, larger screen-to-body ratio, thinner and lighter, and more fashionable and advanced, the technology is not yet particularly mature, so the technology is constantly being updated and upgraded. The price is relatively expensive, and you can consider it if you have a sufficient budget.
3: Key configurations such as CPU and memory:
First of all, let me explain to you that CPU, memory, etc. have nothing to do with the picture quality of the TV; while the size of the CPU, GPU, and memory have nothing to do with the running speed of the TV and whether it is smooth. It is related, just like the CPU of mobile phones and computers, central processor , the more cores it has and the higher the running frequency, the smoother it runs.
First of all, the current TV CPUs all use the ARM architecture, and its CPU model is the Cortex-A series; that is, our common A53/A55/A73, etc.; currently, the best and most mainstream TV CPU is Quad-core processor.You can’t go wrong by choosing the following three CPUs at the moment!
2GB of running memory is good. After all, it’s just a TV, not a computer. 8GB of storage memory is enough. You only need to install software and don’t need to store movie sources. Therefore, 2GB+8GB is enough for use. Of course, if you have a large budget, the bigger the better!
refresh rate: has a minimum of 60HZ, and 120HZ is the best choice, especially when you are going to play games!
4: Choose a true 4K screen:
Many TVs nowadays are basically marked with a 4K screen, which means the resolution reaches 3840※2160; if it is a true 4K screen, it uses the three primary colors of RGB (red, green and blue); and Fake 4K uses RGBW (red, green, blue and white) four colors. White will not increase the effective pixels, but will reduce the sharpness, so please pay attention here!
Another thing is that the effective pixels of a real 4K screen can reach 8.4 million; while the effective pixels of a fake 4K screen are only 6.15 million! So dear friends, don’t be greedy for petty advantages and get fooled!
5: It is best to choose a TV with a picture quality chip:
First of all, not all TVs have picture quality chips. Currently, only mid-to-high-end TVs have picture quality chips, but low-end TVs do not! As mentioned above, the CPU will not affect the picture quality of the TV. Only by having a picture quality chip can the screen quality of the TV be improved. The main function of the
image quality chip: can optimize and repair images, and can enhance the color of the image, improve the clarity, better reduce noise, and make the image softer and brighter.
6: It is best to choose a TV with image quality processing technology:
Common image quality processor technologies currently on the market include: MEMC ( motion compensation ), light control partition, HDR (high dynamic range).
But I would like to emphasize here about HDR; as I just said, HDR has very high hardware requirements, so generally cheap TV sets under 3,000 yuan do not have HDR function. There are many TV manufacturers using HDR because HDR10 is not suitable for all TV manufacturers. open.
First of all, the quickest way to identify whether it really supports HDR is to see if there is a 4K HDR logo, and there is another logo that is the Dolby Vision logo! If is not available, you can analyze or ask customer service whether the screen is a wide color gamut screen. According to national standards: LCD TVs must have a peak brightness of 1,000 nits to support HDR; OELD TVs must have a peak brightness of 550 nits. Talent supports HDR, so everyone needs to pay attention!
7: Interface selection:
Generally speaking, a 4K TV requires at least one HDMI 2.0 interface. HDMI is more important for connecting game consoles and TV boxes. As for USB, USB 2.0 and USB 3.0 are more common. For 4K movies, USB 2.0 transmission 480Mbps is enough. If you are buying a high-end TV, you will need USB 3.0 and HDMI 2.1!
8: Selection of other parameters and functions:
Wide color gamut : TVs with wide color gamut have brighter, more natural colors, better layering, and a stronger viewing experience. Common color gamut standards include: sRGB, NTSC, Adobe RGB, and DCI-P3. 100%sRGB≈72%NTSC is common in computer monitors (more than 72%NTSC is also considered a wide color gamut); ≥90%DCI -P3 (wide color gamut), and anything over 100% BT.709 is also considered a wide color gamut. In addition, during the transition between 4K and 8K TVs, there is a new color gamut standard BT.2020. Compared with BT.709 color In terms of gamut, BT.2020 covers a wider color gamut, especially the orange color gamut.
color calibration: The smaller the △E value, the better the screen color calibration!
system: is best Android!
voice control function: is easy to control, simple and convenient!
9: Finally, I recommend
. If you want good colors, you can choose quantum dot TV, and Mini LED TV. Recently, there is a Mini LED TV-TCL Q10G, which uses micron-level lamp bead chips. The number of lamp beads is a hundred times that of ordinary LED TVs. Above, the peak brightness is up to 1000 nits, the high dynamic range is up to HDR 1000, 98% DCI-P3 movie-level high color gamut, full-channel 4K 120Hz, high configuration and high display, good-looking and fun, friends who like it can try it!
