What is DVI Connector and who are the domestic and international manufacturers of DVI Connector?

A. What is DVI connector?DVI (Digital Visual Interface) connector is a video connector used to transmit digital signals. It is the interface between a digital display (such as an LCD monitor) and a computer graphics card. For the past few decades, the DVI connector has been one of the standard connectors for computer graphics output. In this article, we will take an in-depth look at how DVI connectors work, types, pros and cons, and application scenarios.Types of DVI ConnectorsThere are three types of DVI connectors: the DVI-A, DVI-D, and DVI-I.DVI-A ConnectorsThe DVI-A connector is a connector that transmits only analog signals. It contains 15 pins and is used to connect analog monitors to computer graphics cards.The resolution of the DVI-A connector is usually VGA (640 x 480) or SVGA (800 x 600). However, since it only transmits analog signals, it has been used in relatively few applications.DVI-D connectorThe DVI-D connector is a connector that only transmits digital signals. It contains 24 pins and is used to connect digital displays to computer graphics cards.The DVI-D connector can support high-resolution, high-frame-rate video output, such as WUXGA (1920 x 1200) or 1080p (1920 x 1080). Since it only transmits digital signals, it provides sharper images and is more futuristic than the DVI-A connector.DVI-I ConnectorThe DVI-I connector is a connector that can transmit both analog and digital signals. It contains 24 pins and 4 additional pins and can be used to connect analog and digital displays as well as computer graphics cards.The DVI-I connector is the most versatile of the DVI connector connector types.DVI connectors typically have 24 or 29 pins, four of which are used for transmitting signals, and the rest are used for grounding. These signals include red, green, and blue digital signals (RGB), as well as synchronization signals. In addition, DVI connectors can also transmit audio signals and other control signals.DVI connectors share many similarities with HDMI (High Definition Multimedia Interface) interfaces. Both interfaces can transmit digital signals and provide better image quality and higher screen resolution. However, the HDMI connector can transmit not only video signals, but also audio signals and other data signals such as Ethernet and HDCP (High-bandwidth Digital Content Protection). Although the HDMI interface is more versatile, the DVI connector is still a widely used digital video interface. Because of its reliability and high quality image transmission, many computers and digital video equipment are equipped with DVI connectors. In addition, many LCD monitors and digital projectors also support DVI connectors.The DVI connector is a digital video interface that can be used to connect computers and digital displays. It offers many advantages, including high definition, better image quality, and faster data transfer speeds. Although HDMI interfaces are more feature-rich, the DVI connector is still a widely used digital video interface.
