In daily shopping, the difficulty for many people to choose things is not whether this thing is expensive or not, but when it comes to purchasing, it will consider that this thing is not suitable for you.
As the main screen output device at present, the monitor has always been attracting people's attention. In many display monitor, purchase page, and professional media monitor evaluations, we will see some parameters used to describe the monitor's performance.
And these parameters also determine the quality of the display and its people-oriented, so you want to choose the right display for your own, some parameters we must be familiar with.
size
The size of the display is actually the diagonal length of the display screen. When the aspect ratio is the same, the actual display area is proportional to the length of the diagonal.
For displays with different aspect ratios, such as the now relatively fiery 16:9 and 21:9 monitors, the size comparison does not directly reflect the size of the two screens. For consumers, we only need to know that the closer the screen is to a square, the larger the actual display area.
Resolution
Resolution can be said in the display area has always been the focus of attention, we often say that the resolution is a representation of the number of vertical and horizontal pixels on the screen, such as now common 1920x1080 resolution refers to the horizontal 1920 pixels on the screen , There are 1080 pixels in the portrait.
The more pixels there are in the display, the more targets can be displayed at the same exquisite level, or the same display target can be more delicate, and at the same size, the higher the resolution, the finer the display target, but also There is a problem with the target size being too small.
After we have finished the two most basic parameters, let's take a look at what parameters need to be paid attention to by different applicable people.
Home office
Many people think that this kind of display can be bought as you like. Nothing is too high. Actually, this type of display is far longer than other monitors in terms of duration and frequency of use. Therefore, our requirements for such displays cannot be overdone. Low, and these requirements are often reflected in the following two points.
brightness
In general, a brightness of 250cd/m2 is enough for everyday use. A high-brightness display can be more clear when displaying some dark scenes, but the screen will be too bright and stimulate the eyes during normal use. It is easy to fatigue when using eyes for a long time.
Since we use such displays for too long, for the sake of our eyes' health, we must pay more attention to this parameter at the time of purchase.
Contrast
We all know that high contrast can bring about a better display hierarchy. In general, a contrast ratio of 200 can provide a good display effect. Some manufacturers blindly improve the brightness to achieve high contrast, which is not helpful for practical use. Reduced service life.
And now many monitors on the market have more serious falsification on this parameter. Everyone must pay more attention when buying.
Game gaming
Due to the current e-sports market, e-sports displays have become one of the necessary equipment for many game enthusiasts. Because of this, the e-swimming market is now seeing so many fish-smelling products. For the friends of the display, the following parameters can be used to identify the authenticity.
Refresh rate
The refresh rate refers to how many frames per second the monitor can update. Currently, the mainstream 60Hz LCD monitor can guarantee a comfortable viewing.
However, in the fierce competition in eSports, it is necessary to quickly update the scene picture, so there has been a display with a refresh rate of 144Hz or higher. The price of e-sports displays is now close to that of the people.
However, before buying, you must consider your own configuration. If the graphics card does not support a high refresh rate, you will not be able to experience the smooth experience brought by the high refresh rate.
Response time
The response time now referred to generally refers to the gray-scale response time that is closer to the actual usage. The response time reflects the actual performance of the display screen conversion capability. The shorter the response time, the more neat the screen transitions, otherwise the refresh rate is very high. high.
Because the conversion speed is not fast enough, the residual color of the previous frame in the new frame will also be caused, that is, the so-called smear phenomenon. The response time of mainstream e-sports displays has fallen below 5ms, which can solve the problem mentioned above. Smear phenomenon.
Synchronization technology
In many cases, the screen refresh of the monitor and the output screen of the graphics card cannot be synchronized, which may cause the phenomenon of tearing of the screen. In order to alleviate this phenomenon, the two major display card manufacturers and the display manufacturers have introduced two synchronization technologies—G. -Sync technology and FreeSync technology to coordinate the brushing speed of the monitor and the speed of the graphics output screen.
High-end professional
Such users have much higher display requirements than other users, especially in terms of color requirements. Therefore, these consumers should pay more attention to the color parameters of the monitor when purchasing a professional monitor.
Color gamut
The color gamut of a monitor is simply the number of colors it can display. This is mainly related to the precision of the control chip and the display unit.
At present, our common display color gamut standards are sRGB, Adobe RGB, and NTSC color gamut. sRGB is sufficient for general users, while Adobe RGB and Apple RGB are more common on professional monitors and professional software. For design, art, etc. Professionals.
Color depth
Each pixel of the display is composed of RGB (red, green, blue) display cells of three primary colors. Their light and shade are differently combined into the colors presented by this pixel.
How many bits are used in the display? How many bits are used in the display? For example, in mainstream 8-bit color, there are 256 changes in each display unit. The combination of colors in a single pixel is 256×256×256=16,777,216 (that is, The 24-bit true color) basically reached the visual limit of the average person.
In pursuit of extremes, 10bit or higher display products have appeared on the market.
HDR
HDR is the English abbreviation of high dynamic lighting rendering. It refers to the way of dynamically presenting contrast and color accuracy according to the scene conditions. For example, a game player in a black scene, the ordinary monitor is almost a mass of black, but the monitor has HDR. You can see some scenes in the dark.
5 slogan seated inside and outside is the key to the author's introduction, presumably we have a certain understanding of some parameters of the monitor mainstream, we can focus on their needs in the purchase focus on a few points, find the right monitor.
Write to the end:
After understanding the basic parameters described above, we can basically understand the capabilities of this machine when we see the performance parameters of the display.
Of course, in addition to these parameters, appearance, control design, adjustment capabilities, and interface settings are also factors that affect consumers' purchases. Therefore, for future display products, internal and external acquisitions must win the favor of consumers.
