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. (canceled)

2. 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 interface;

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

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

3. The method of claim 2, wherein the image data signal format associated with the first image data interface is different from the image data signal format associated with the second image data interface.

4. The method of claim 2, 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.

5. The method of claim 2, further comprising:

detecting the first image data interface; and

detecting the second image data interface.

6. The method of claim 2, further comprising:

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

7. 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 the first image data interface, to identify an image data signal format associated with the second image data interface, and to perform a selection of one of the first image data interface and the second image data interface.

8. The system of claim 7, wherein the image data signal format associated with the first image data interface is different from the image data signal format associated with the second image data interface.

9. The system of claim 7, 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.

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

11. The system of claim 7, wherein the controller is further configured to update the selection of one of the first image data interface and the second image data interface.

12. 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 interface; and

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

wherein the first image data interface and the second image data interface operate simultaneously.

13. The method of claim 12, wherein the image data signal format associated with the first image data interface is different from the image data signal format associated with the second image data interface.

14. The method of claim 12, further comprising:

detecting the first image data interface; and

detecting the second image data interface.

15. The method of claim 12, further comprising:

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

16. The method of claim 15, further comprising:

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

17. 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 the first image data interface and to identify an image data signal format associated with the second image data interface;

wherein the first image data interface and the second image data interface are configured to operate simultaneously.

18. The system of claim 17, wherein the image data signal format associated with the first image data interface is different from the image data signal format associated with the second image data interface.

19. The system of claim 17, wherein the controller is further configured to detect the first image data interface and to detect the second image data interface.

20. The system of claim 17, wherein the controller is further configured to perform a selection of one of the first image data interface and the second image data interface.

21. The system of claim 20, 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.
