When we consider the video performance parameters of notebook computers, we generally need to consider three factors: screen size, resolution and the performance of mobile display chip. Most users often focus on the screen size and resolution of notebook computers, and often ignore the performance of display chips. In fact, the performance of display chip plays a vital role in the video processing ability of a notebook computer. Therefore, when measuring the video performance parameters of notebook computers, we need to comprehensively consider these three. Screen size the screen size of notebook computer varies according to different types of notebook computers. Generally speaking, the display screen with large screen is easier to read. In the alternative desktop notebook, the display screen with large screen is generally selected. In the ultra light portable model, in order to be easy to carry, the display screen size is generally relatively small. With the introduction of the concept of portable media center, many notebook products now use LCD display with special aspect ratio. Or adopt ultra-thin display screen to reduce the volume of the whole machine. We often see that the so-called 14 inch TFT display screen is introduced in some promotional materials of notebook computers. In fact, the 14 inch here does not refer to the length, width or height of the display screen, but to the diagonal length of the display screen. That is, the distance from the low-end corner to the high-end corner of the display. Different from CRT display, the diagonal length here in LCD display is the size of visual grid. The following table shows typical LCD display sizes for different types of laptop configurations:

Resolution screen resolution refers to how many pixels are arranged along the length and width of the screen. Due to the display characteristics of LCD, LCD has the so-called original resolution, and its best resolution is its original resolution. Of course, you can also use other display settings lower than the original resolution on the LCD display. At the same time, some special algorithms can be used to make the LCD display higher resolution. However, the display effect of both resolutions is not as good as using the best resolution. Higher resolution can display more image details and provide greater visual range. However, too large resolution also has disadvantages: the font may become too small to read. This is a big problem for some people with poor eyesight. Of course, you can also take a simple method to change the system font to solve this problem. However, this practice may lead to some unpredictable consequences in some programs. The following table lists the common resolutions of different types of LCD displays:
