interface is the most widely used type of interface on the graphics card, the vast majority of graphics cards have this type of interface. The port has a male and a female \ two males \ two females \ category
interface is a D-type interface, a total of 15 pinholes, divided into three rows, five in each row. Among them, in addition to the two NC (Not Connect) signals, three display data bus and five GND signals, the more important is the three RGB color component signals and two scanning synchronization signals HSYNC and VSYNC pins. color component in the interface using the RS343 level standard. the peak-to-peak voltage of the RS343 level standard is 1 V. The interface is the most widely used type of interface on the graphics card. interface is the most widely used type of interface on the graphics card, and most of the graphics cards come with this type of interface. Some graphics cards that do not come with a connector, but do come with a DVI (Digital Visual Interface) connector, can also be converted from DVI to with a simple adapter, which is usually included with cards that do not have a connector.
Today, most computers and external display devices are connected through the analog interface, the computer's internal digitally generated display image information, the graphics card in the digital / analog converter into R, G, B color signals and line, field synchronization signals, the signal through the cable transmission to the display device. compatible with the analog display devices, such as analog CRT monitors, the signal is sent directly to the corresponding processing circuit, drive control of the picture tube to generate images. compatible with the LCD, DLP and other digital display devices, display devices need to configure the corresponding A/D
