DMS-59 connector DMS-59 connector pinout details DMS-59 to dual VGA adapter. DMS-59 (Dual Monitor Solution, 59 pins) was generally used for computer video cards. It provides two Digital Visual Interface (DVI) or Video Graphics Array (VGA) outputs in a single connector. A Y-style breakout cable is needed for the transition from the DMS-59 output ...
Five variants are: DVI-I single link, DVI-I dual link, DVI-D single link, DVI-D dual link, and DVI-A. Male Mini-DVI plug on top of a 12-inch PowerBook G4; female port is second from left. Mini-DVI: VGA, DVI, television. Apple Computer alternative to Mini-VGA. Often now replaced by Mini DisplayPort. Female Micro-DVI port (rightmost) on MacBook Air
A passive DVI-to-VGA adapter. This adapter will not work with a DVI-D output. It requires a DVI-I or DVI-A output to get the analog signal to a VGA input (even if the adapter looks like a DVI-D). A more expensive active adapter (or converter) is required to connect DVI-D to VGA.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
An active DisplayPort adapter can convert a DisplayPort signal to another type of signal—like VGA, single-link DVI, or dual-link DVI; or HDMI if more than two non-DisplayPort displays must be connected to a Radeon HD 5000 series graphics card. [7]
VGA connector A type of D-sub connector standard on most video cards; Mini-VGA Found on some laptop computers; 5 BNC Connectors can also be used to carry the VGA signal as R, G, B, HSync, VSync; Digital Visual Interface (DVI) A hybrid analog/digital connector commonly found on PC graphics cards and LCD monitors; Mini-DVI Found on some Apple laptops
Project VGA aims to create a low-budget, open-source VGA-compatible video card. [104] The Open Graphics Project aims to create an open-hardware GPU. The Open Graphics Device v1 has dual DVI-I outputs and a 100-pin IDC connector. In September 2010, the first 25 OGD1 boards were made available for grant application and purchase. [105]
Various adapters can be purchased to convert VGA to other connector types. One common variety is a DVI to VGA adapter, which is possible because many DVI interfaces also carry VGA-compatible analog signals. Adapting from HDMI or DisplayPort to VGA without an active converter is not possible because those connectors don't output analog signals.
