Abstract

A display is capable of displaying images in response to signals of a plurality of signal formats. The display includes a controller that is coupled to a plurality of image data interfaces. When the plurality of image data interfaces are simultaneously operating, the controller selects one of the plurality of image data interfaces according to preference variables associated with each of the plurality of image data interfaces. Each of the preference variables may indicate a relative priority of an image data signal format associated with the corresponding image data interface. In addition, each of the preference variables may indicate one or more performance metrics associated with the quality of image data signals received from the corresponding image data interface.

Claims

1. A method for establishing operation between a processor and at least one of a display and a display adaptor, comprising:

identifying an image data signal format associated with a first image data standard and a first image data interface;

identifying an image data signal format associated with a second image data standard and a second image data interface; and

performing a selection of one of the first image data interface and the second image data interface;

wherein the first image data standard is different from the second image data standard.

2. The method of claim 1, wherein the performing the selection of one of the first image data interface and the second image data interface is according to a preference variable.

3. The method of claim 1, further comprising:

detecting the first image data interface; and

detecting the second image data interface.

4. The method of claim 1, further comprising:

updating the selection of one of the first image data interface and the second image data interface.

5. A system comprising:

a first image data interface;

a second image data interface; and

a controller configured to identify an image data signal format associated with a first image data standard and the first image data interface, to identify an image data signal format associated with a second image data standard and the second image data interface, and to perform a selection of one of the first image data interface and the second image data interface;

wherein the first image data standard is different from the second image data standard.

6. The system of claim 5, wherein the controller is configured to perform the selection of one of the first image data interface and the second image data interface according to a preference variable.

7. The system of claim 5, wherein the controller is further configured to detect the first image data interface and to detect the second image data interface.

8. The system of claim 5, wherein the controller is further configured to update the selection of one of the first image data interface and the second image data interface.

9. A method for establishing operation between a processor and at least one of a display and a display adaptor, comprising:

identifying an image data signal format associated with a first image data standard and a first image data interface; and

identifying an image data signal format associated with a second image data standard and a second image data interface;

wherein the first image data interface and the second image data interface operate simultaneously and wherein the first image data standard is different from the second image data standard.

10. The method of claim 9, further comprising:

detecting the first image data interface; and

detecting the second image data interface.

11. The method of claim 9, further comprising:

performing a selection of one of the first image data interface and the second image data interface.

12. The method of claim 11, further comprising:

updating the selection of one of the first image data interface and the second image data interface.

13. A system comprising:

a first image data interface;

a second image data interface; and

a controller configured to identify an image data signal format associated with a first image data standard and the first image data interface, to identify an image data signal format associated with a second image data standard and the second image data interface;

wherein the first image data interface and the second image data interface are configured to operate simultaneously and wherein the first image data standard is different from the second image data standard.

14. The system of claim 13, wherein the controller is further configured to detect the first image data interface and to detect the second image data interface.

15. The system of claim 13, wherein the controller is further configured to perform a selection of one of the first image data interface and the second image data interface.

16. The system of claim 15, wherein the controller is further configured to update the selection of one of the first image data interface and the second operating image data interface.

17. A system comprising:

a display interface;

a processor configured to receive, via the display interface, an image data format from at least one of a display and a display adaptor, to send, via the display interface, image data to the at least one of the display and the display adaptor if the image data format is supported, and to request, via the display interface, a different image data format from the at least one of the display and the display adaptor if the image data format is other than supported; and

a graphics subsystem configured to determine if the image data format is supported;

wherein the at least one of the display and the display adaptor is configured to provide the image data format and the different image data format according to a priority scheme.

18. A system comprising:

an image data interface; and

a processor configured to receive, via the image data interface, an image data format from at least one of a display and a display adaptor, to determine if the image data format is supported, to send, via the image data interface, image data to the at least one of the display and the display adaptor if the image data format is supported, and to request, via the image data interface, a different image data format from the at least one of the display and the display adaptor if the image data format is other than supported;

wherein the at least one of the display and the display adaptor is configured to provide the image data format and the different image data format according to a priority scheme.

19. The system of claim 18, wherein the processor is further configured to send, via the image data interface, a request for the image data format to the at least one of the display and the display adaptor.

20. A system comprising:

an image data interface; and

a controller configured to receive, via the image data interface, a request for an image data format from a processor and to provide, in response to the request for the image data format, one of a first image data format and a second image data format according to a priority scheme.

21. The system of claim 20, wherein the controller is further configured to determine which of the first image data format and the second data format has previously been provided according to the priority scheme.
