Abstract
A system and method for detecting a display connection. The system includes a transmitter operable to be coupled to a receiver. The transmitter includes a controller operable to generate a connect signal when the receiver is coupled to the controller and is further operable to generate a disconnect signal when the receiver is uncoupled from the controller. The transmitter further includes a detection component operable to detect the connect signal and is further operable to detect the disconnect signal.
Claims20
A graphics system for detecting a digital display connection to a receiver comprising:
- a transmitter operable to be coupled to said receiver, where said transmitter comprises:
- a controller operable to generate a connect signal when said receiver is coupled to said controller and wherein said controller is further operable to generate a disconnect signal when said receiver is uncoupled from said controller;
- and
- a detection component operable to detect said disconnect signal and wherein said detection component is further operable to detect said connect signal and wherein a digital output is selectively enabled in response to said detection component detecting said connect signal.
A method for detecting a display connection to a display, comprising:
- sampling a sense line;
- in response to said sampling, generating a connected signal when a transmitter is coupled to said display;
- in response to said sampling, generating a disconnected signal when a transmitter is uncoupled from a display;
- in response to said generating, detecting whether said connected signal is generated or said disconnected signal is generated;
- and
- enabling a digital video output if said connected signal is generated.
A GPU (graphics processor unit) comprising:
- a pipeline for facilitating graphics processing;
- an interface for coupling said GPU to a computer system;
- a plurality of output connectors for coupling said GPU to a display device;
- and
- a circuit for detecting a digital connection via at least one of said output connectors coupled to said GPU, wherein said circuit comprises:
- a controller component operable to generate a connect signal when said receiver is coupled to said controller and wherein said controller is further operable to generate a disconnect signal when said receiver is uncoupled from said controller;
- and
- a detection component operable to detect said disconnect signal and wherein said detection component is further operable to detect said
- connect signal and wherein a digital output is selectively enabled in response to said detection component detecting said connect signal.
