Dual DVI is a digital video interface connector with 24 pins arranged in a grid-like rectangular format on the right side. The dual DVI interface connector is also called dual link, and it can be used as a connector on electronic devices such as personal computers or high-definition televisions (HDTV). This article mainly introduces you to what is the dual DVI interface connector!
Dual DVI interface connector
The DVI connector is a digital video interface, also known as a digital video interface, which debuted in 1999. It was designed by the Digital Display Working Group (DDWG). This is an open industry alliance established by seven consumer electronics companies: Intel Corporation, Fujitsu Corporation, International Business Machines Corporation (IBM?), Hewlett-Packard (HP?), NEC Corporation, SiliconImage? , Inc and Compaq Computer, which merged with HP two years later.
DVI connectors are replacing VGA connectors for video graphics arrays. The VGA connector was still commonly used to connect the monitor to a desktop PC or used as an external monitor connector for a laptop as of 2011. Compared with VGA, which transmits analog video signals, properly named DVI is used for digital video display.
The double DVI pin is responsible for the passage of digital video signals. Dual DVI has six more pins than single DVI. The number of pins in a single-link DVI connector is 18. The additional pins on the dual-link DVI connector increase the bandwidth, which is the frequency range required to transmit video signals.
Therefore, dual-link DVI allows higher graphics display resolution than single-link DVI. The graphic display resolution represents the number of pixels that can be placed on the display. A single DVI can manage resolutions up to 1,920 x 1,200 pixels. Dual DVI surpasses single DVI, with a maximum display quality of 2,560 x 1,600 pixels.
Another result of the increased bandwidth of dual-link DVI is the ability to transmit signals farther than single DVI. The established maximum cable length standard for DVI cables is approximately 16 feet (5 meters). Dual DVI interface connectors can not only transmit digital video signals, they can also accommodate analog mono, which is the same as VGA connectors. The two types of dual-link connectors are: DVI integrated (DVI-I) and DVI-digital (DVI-D). DVI-I contains digital and analog video pins to adjust any type of computer camera, while DVI-D is only used for digital visual display.
