The market for computer monitors is actually relatively stable, and it is also relatively easy to buy. Unlike mobile phones, there are a lot of parallel imports. The monitors that are said now are generally LCD, so what do you need to see when the monitors are purchased?
Now whether it is Jingdong or Suning Tesco, they will use the display as the main selling point in the promotion, but a lot of data is not reliable, not just ordinary consumers, even professionals will be deceived, so many consumers I won't know which monitor is good for them.
1, the field of view of the display
The visual range is the range that the user can see clearly in front of the screen. The larger the viewing range, the easier it is to navigate; the smaller the user, the smaller the viewing position, the more likely the picture will not be comprehensive or even clear. The visual range refers to the range of angles from the middle of the screen to the top, bottom, left, and right directions. The larger the value, the wider the range is naturally, but the range in the four directions is not necessarily symmetrical.
2, do not buy the open display
Many manufacturers' seals have the function of designing anti-reclosure. This kind of seal is very sticky and cannot be recovered after opening. If the display adopts this kind of packaging, it is of course easy to distinguish.
However, some embarrassing dealers will use the hair dryer method to open the package. When they open the box, they will use the hair dryer to hang the heat on the seal beforehand, and then soften the seal and then open the seal. This method opens the box and looks more neat. If the seal is attached, Be careful and it won't be easy to identify. But we also have countermeasures. If you look at the packaging a few times carefully, you will find their flaws.
3, see the contrast
The higher the contrast, the more vivid the color is saturated, and the three-dimensionality will appear. The contrast is low, the color is poor, and the image becomes flat. Contrast values ​​vary widely, from 100:1 and 300:1, or even higher.
4, the brightness of the display
The higher the brightness value, the more natural the picture is. The unit of brightness is cut [Dera] per square meter (cd/m2). A typical LCD brightness value is 150 cd/m2, while some can reach 250 cd/m2.
