Abstract
Data processing apparatus including a display monitor operable in response to a display signal of predetermined frequency and a computer for transmitting a display signal to the display monitor. The display monitor generates an identifier signal indicating the predetermined frequency at which the display monitor operates. The computer means uses the identifier signal to determine the frequency of the display signal.
Claims11
Data processing apparatus including:
- display means operable in response to a display signal of predetermined frequency to display graphics image, said display means having at least a refresh rate and a display resolution which together define said predetermined frequency, said display means also having identifier means for generating an identifier signal indicating said predetermined frequency;
- and
- data processing means for transmitting said display signal to said display means at a selectable transmission frequency, said data processing means having frequency deciding means for selecting said selectable transmission frequency to equal the predetermined frequency of said display signal in response to said identifier signal.
A display device for a computer system comprising:
- display means for generating a graphic display in response to a display signal of predetermined frequency, said display means having at least a refresh rate and a display resolution that together define said predetermined frequency;
- and
- identifier means for generating an identifier signal indicative of said predetermined frequency.
A data processing system including a processor and memory for processing data and generating output in the form of a display signal at an output display signal frequency, said data processing system comprising:
- means for receiving a signal indicative of a predetermined display device signal frequency, said display device signal frequency identifying at least a display resolution and display refresh rate;
- and
- frequency deciding means for setting the output display signal frequency as the frequency received by the means for receiving.
