The monitor is an important window for displaying the contents of the computer, and using a monitor with excellent screen quality can make the process of using the computer more enjoyable.
We all understand the reasoning, but not everyone knows the monitor parameters like the back of their hand. Many people are not sure how to choose in the face of monitor parameters.
Today we will talk to you about those parameters related to the monitor screen, I believe that after reading this article, you will be able to do the selection of the screen according to the parameters of the monitor.
The monitor panel material, resolution, color display and other parameters, the final presentation of the screen have a greater impact on the effect. Here’s what the panel material is.
01 Panel material
The display panels currently on the market are basically liquid crystal panels (LCD), and because the liquid crystal material itself does not emit light, there is a backlight panel and reflective film on the back of the LCD to provide a background light source. Most of the LCD panels use TFT drive method. And according to the different forms of liquid crystal molecule arrangement, divided into TN, VA, IPS three kinds of panels, these three have advantages and disadvantages, the following detailed description for you.
TN panel: the full name of this panel TwistedNemaTIc panel. It has a fast response time, high refresh rate characteristics, more suitable for gaming monitors. But the viewing angle of this panel is weak, the color display is weak, the color requirements of the higher crowd is not suitable for this panel.
VA panel: this type of early panel was born to make up for the disadvantages of the TN panel, improved viewing angle reduced response speed. In the late development, gradually improve the contrast and response time. Currently the biggest advantage of this panel is the high contrast ratio, display pure black background is more pure. But the disadvantage is also more obvious, 1 is the gray scale response speed is still not as fast as the VA panel, 2 is the screen color uniformity is weak, some scenes will have color shifts. So this panel is suitable for mid-range, sub-flagship entertainment display, used as a professional design display will be slightly strained.
IPS panel: This panel is called In-PlaneSwitching in English, and it was created to solve the problem of low viewing angle and poor color display quality of TN panels. It is currently the widest viewing angle of the panel technology, and solve the problem of color shift, so that the color display more accurate. So this panel in the color accuracy requirements of the scene is very popular, the general flagship level products will choose IPS panel to protect the display color display effect.
Summary: If you want to have a monitor with a better display, then the IPS panel is your primary choice.
02 Screen Resolution
Resolution is a fixed value in LCD monitors, which is determined by the number of cells in the LCD liquid crystal layer. 1080P, 2K, 4K, etc. are the parameters that indicate the resolution. It represents the number of horizontal and vertical pixels.
Not easy to understand? Easy, let’s take an example.
A display panel with a screen ratio of 16:9 and a resolution of 2K (25601440). Horizontally, this display panel has 2560 pixels, and vertically, it has 1440 pixels. The total number of pixels is 25601440=3686400.
Similarly, a display panel with 4K resolution (3840*2160) has 3840 pixels in the horizontal direction and 2160 pixels in the vertical direction. The total number of pixels is 8294400.
It is important to note that the resolution parameter does not change with the screen size. So, the higher the resolution, the more pixels the panel has, given the same screen size. The finer the picture and the better the display quality.
Through the calculation can be found in the same size and screen ratio, 4K resolution panel than 2K resolution panel, more than 4.6 million pixel points; than 1080P resolution panel to more than 6.2 million pixel points.
The display of a high-resolution monitor is not simply a linear improvement. All other prerequisites being equal, it is right to choose a monitor with a higher resolution.
03 Screen color performance
Through the previous knowledge we know that a monitor with IPS panel and higher resolution can bring better picture effect. Although the screen effect is good, but it is still not clear how specific performance. Next, we will talk to you about a few parameters that can represent the color performance of the screen, so that you can see the quality of the screen more intuitively.
Color depth: the English name Colordepth, unit bit. it refers to the color level, 8bit has 256 gray scale, provides 167,000 colors. 10bit has 1024 gray scale, provides 107 million colors. The more grayscale, the finer the color, the more natural the color transition will be, and the higher quality of the display panel.
Color gamut: The current mainstream color gamut standards are sRGB, AdobeRGB and NTSC. sRGB color gamut was developed by Microsoft and HP, it is the most widely applicable, and most digital devices currently support sRGB display; NTSC has the most extensive color coverage, and it is a standard based on the broadcast television transmission protocol. When buying a monitor, movie lovers can focus on the performance of this color gamut coverage; AdobeRGB is the color gamut standard introduced by Adobe, and design professionals can pay more attention to the monitor’s coverage performance under this color gamut.
The higher the color gamut value, the richer the color representation will be. Displays with high color gamut generally have to achieve 100% sRGB or 72% NTSC color gamut coverage.
DeltaE: It refers to the deviation value of the display panel color from the standard color, which can also be written as △E. This value can be improved by color calibration, but it will be affected by the hardware quality. Generally speaking, when the average △E value is less than 3.2, the human eye basically can not distinguish the difference in color.
If you want to buy a monitor with excellent display effect, you can determine the final display effect by comparing the specific values of these three parameters on the basis of IPS panel and high resolution.
04 Written in the end
I believe that after understanding these few common color parameters, we all understand how to buy a monitor with good display effect. But only a strong performance of the panel, and does not guarantee you a better use experience.
Because the panel to be embedded in the monitor to use, if the monitor screen side of the four black thick border, then the view naturally will not be very good. In order to protect the final experience, choose a monitor with a narrow bezel is a wise choice.
Philips 279C9 is a recently launched bezel-less monitor, when using this monitor, the four-sided bezel-less design allows high-quality images to be better rendered, the user’s view is more immersive.
The panel of this monitor is also strong. It is equipped with a 27-inch 4K resolution IPS panel, which has excellent picture display capabilities. The screen color performance, it has 10bit color depth, can display 1.07 billion colors; support 109% of sRGB and 90.7% of NTSC; average △E value at 0.75, well meet, the needs of accurate color display.
It is worth mentioning that this monitor provides a Type-C interface, which allows users to increase their experience significantly. Although 4K resolution can bring a more detailed display screen, but the requirements for data transmission are also increased. When using the HMDI1.4 connection, the maximum screen refresh rate at 4K resolution is only 30Hz.
While the Type-C interface uses the DP1.4 transmission protocol, it has a maximum transmission rate of 32.4Gbps, which is about four times that of HDMI1.4. At the same time, the Type-C interface can also transmit video signals along with power and data transmission. The notebook can be connected to just one Type-C cable for display signal access, notebook charging, and display USBHUB expansion, which improves convenience in daily use.
The four-sided bezel-less guarantee the final effect of the screen display, while the Type-C interface optimizes the daily use experience. If you have not yet considered which monitor to buy with excellent display quality, you can consider the Philips 279C9 this monitor.
