A method and interface for controlling a display monitor through a multi-channel coupler detects a type of the display monitor and selects a channel plan defining a connectivity between the channels of the coupler, based on the type of the display monitor. The channel plan defines a connectivity between the channels of the coupler and a plurality of display control signals. Each channel of the coupler is connected in accordance with the selected channel plan. The display types can be for example analog or digital. The method and apparatus can be used to drive two analog display monitors from a DVI-I compliant interface.

Analog multi-display using digital visual interface

The computer motherboard-mounted card such as a dual-head graphics card has two I/O connectors and two footprints positioned one behind the other for accommodating two different output types. A right-angle, vertical edge, I/O connector mounted in a selected one of the two footprints. The I/O connector can be selectively connected to a farther one of the two footprints from a vertical edge of the computer card and be provided with a correspondingly horizontally elongated body.

Adaptable computer card I/O connection

Provides an apparatus and method for displaying dual Digital Visual Interface (DVI) displays simultaneously, with independent images, by using a Transition Minimized Differential Signaling (TMDS) serializer with dual channels and one clock. Also provides an apparatus and method allowing either two low-resolution displays or one high-resolution display to be driven by a reduced circuit.
