The price difference of monitors is so big, so what's the difference between them?

As the saying goes, a penny is worth a penny, and so is the category of monitors. The main reason for the big price difference is the different configuration. The low version is cheap but the experience is poor, and the high version is expensive but the experience will undoubtedly be better. There is no absolute right or wrong when choosing, but more depends on personal needs.

Of course, this is just a general difference. Subdivided, the configuration of the display covers many aspects. Here, I will explain it in detail for your reference.

1, panel type Panel type is a big consideration, which determines the color, contrast, response time, viewing angle and other important parts of the display. At present, there are mainly two types of display panels, namely LCD and organic light emitting diode. LCD mainly changes the backlight degree of LED through the deflection of liquid crystal molecules, so as to realize picture display. Because of the different liquid crystal materials and internal driving methods, it can also be subdivided into IPS, VA and TN. IPS panel has high viewing angle, good color performance and better screen quality than other panels, so it is also the mainstream panel type in the market, but its disadvantages are high price and so-called bright black which is easy to be criticized and leaked.

TN panel has fast response speed, but its color performance is often poor and its viewing angle is small. If you look at the screen from a slight angle, the color will turn white, but the TN panel has low cost and relatively cheap price. The viewing angle of VA panel is also relatively high, and the color reproduction degree is not bad. Even if the lights are turned off, there is no obvious light leakage, but the biggest problem is that the response time is long, the smear is serious, and the VA screen with poor quality even has the feeling of dynamic blur when watching moving pictures.

In addition, there is another OLED panel. The difference between organic light-emitting diodes and traditional LCD screens lies in the way of light emission. Organic light-emitting diodes can emit light by themselves only by positive and negative circuits and light-emitting diodes. Because there is no backlight, the black color of the organic light emitting diode is really black, and there is no problem of light leakage. In addition, in contrast, it shows a wider color gamut, faster response, higher contrast, and even more energy saving. Of course, there are also disadvantages, that is, the general price is higher, and then there may be a problem of burning the screen.

2. Resolution Resolution is the number of pixels in a single row and a single column in the horizontal and vertical directions of the display. The higher the resolution, the more pixels on the display screen, and the richer the content that can be displayed. However, it should be noted that the greater the resolution, the clearer it will be. It is PPI (pixels per inch) that determines the clarity of the display. For example, the PPI of a 24-inch 1080* 1920 resolution display is about 9 1, which is very clear for ordinary people (the viewing distance is about 60 cm) and does not feel graininess.

However, the PPI of the 32-inch 1080* 1920 display screen is around 68. If the viewing distance is 60 cm, there will be obvious graininess. At the same resolution, the smaller the display size, the higher the PPI and the clearer it looks. The choice of size and resolution needs to be determined according to personal needs and desktop space. Generally speaking, the resolution of 1080P is 24 inches and below, 27 inches and above 2K, 32 inches and above 2K or 4K.

3. Color gamut The color gamut we are talking about is generally made according to CIE 193 1 Color gamut chromaticity diagram (color gamut visible to human eyes). Common color gamut standards include sRGB, NTSC, AdobeRGB and DCI-P3. The larger the color gamut value, the more colors the display can display. For example, a 95% sRGB color gamut means that 95% of the colors in the sRGB color gamut standard can be displayed. SRGB color gamut is one of the earliest color gamut standards and the most commonly used color gamut standard at present. Most of the pictures and videos on the network media are displayed in sRGB color gamut standard, so it is enough for our daily monitors to consider this.

NTSC color gamut is more suitable for TV display field, while AdobeRGB color gamut is equivalent to an upgraded version of sRGB color gamut, but the display on turquoise system is improved. The professional color gamut is DCI-P3, which is suitable for the design field that pays attention to color expression. If it is an office monitor used in this field, you need to pay attention to the value of this piece. In a word, ordinary users can choose a display with a color gamut greater than 95% sRGB, and DCI-P3 high color gamut display can be selected in the design field that pays attention to color expression.

In fact, organic light-emitting diodes (OLEDs) are not a new display technology, and have been used in the field of television for many years. Although the number of organic light-emitting diode displays on the market is still relatively small, personally, there is no need to worry about stability and durability. If you look at the difference, the traditional LCD and OLED are completely different in structure. The traditional LCD screen can be lit mainly by the backlight layer and colored by the liquid crystal layer and color filter. Organic light-emitting diode (OLED) screen is a spontaneous light screen, and each LED can not only control its own light emission, but also carry out color conversion independently. Compared with the traditional LCD screen, the organic light-emitting diode screen will be more pure in color display, especially the pure black color after the light-emitting diode is turned off, which is more profound and true.

If you are playing games from the media, it is not recommended to buy a traditional LCD screen, because its LCD layer can not be completely closed and the color accuracy is not enough, such as black. The black displayed by LCD is actually a gray mixed with black and white, just like holding a white flashlight to take a black film. If you play a game, the game experience will be worse, and if you are from the media, it will also affect the visual effect. Generally speaking, you get what you pay for, but the display screen, as a relatively mature technology, can meet the needs in general household and office use, so the cost performance is an aspect worthy of attention.

For example, due to the nature of my work, I have high requirements for all aspects of the display, so the price can only rank second, while the performance and configuration rank first. In other words, I am willing to spend more money to buy better products and experience better.

Any kind of commodity carries multi-level services. Usually, the basic function of a commodity is very cheap, that is, it is worth the money. But superimposed services are often much more expensive, which means ten points and two points. The same is true for displays. Ordinary monitors are not expensive, but monitors with higher resolution, larger screen and wider color gamut are naturally expensive.
