The screen size refers to the length of the diagonal of the LCD screen in inches. At present, the screen sizes of mainstream products are mainly 24 inches and 27 inches.
It refers to the multiplication ratio of how many pixels are divided in the horizontal and vertical directions of the screen. Due to different screen ratios and different graphics card outputs, the resolutions are all different. Commonly, there are 1920 * 1080, 1366 * 768, etc. Popularity such as 3840 * 2160 and so on.
Refers to the vertical and horizontal ratio of the screen picture. The screen aspect ratio can be expressed by the ratio of two integers. The widescreen is 16: 9 and 16:10, and the super widescreen resolution of 21: 9 is above 2K.
The biggest feature of the IPS panel is that its two poles are on the same surface, and the liquid crystal molecules are always parallel to the screen regardless of the state, which will reduce the aperture ratio and reduce the light transmittance.
VA panel is a type of panel with high-end LCD applications. It belongs to wide viewing angle panel. Can provide 16.7M color and large viewing angle is the capital of this type of panel positioning high-end, but the price is relatively expensive.
TN panels have become the most widely used entry-level LCD panels due to their low production costs, and are widely used in mainstream mid-to-low-end LCD displays currently on the market.
The DisplayPort interface is a high-definition digital display interface standard that connects computers and monitors. The transmission bandwidth is currently the largest, better than interfaces such as HDMI, and can support 10.8Gb / S transmission speed.
DVI and HDMI
Under the current circumstances, the image quality of the two interfaces of DVI and HDMI is not significantly different at the same resolution, but with the development of the HDMI interface, it can provide more functions than the DVI interface.
Also called D-Sub interface, the most widely used interface type on displays, most displays have this interface.
Screen refresh rate
The refresh rate is the number of screen refreshes per second. The higher the better, the more stable the image, the more natural and clear the image display, and the smaller the impact on the eyes. 144HZ is currently the highest refresh rate value for gaming displays.
The contrast ratio is the ratio of the brightest (white) and darkest (black) brightness at the same point on the screen. A high contrast means relatively high brightness and vividness of the color.
Products with short grayscale response time have fewer shadows and better picture quality, especially when playing moving images, so gamers or users who like to watch movies can consider this parameter of the LCD monitor more.
In contrast, the larger the contrast measured at the maximum viewing angle, the better. Currently the viewing angle reaches 178 °.
