Abstract

Described is a method and system a system and method for dynamically and intelligently configuring a computer system'"'"'s video-related settings upon connection of a monitor, and/or reconfiguring upon disconnection. A monitor configuration may include one or more display mechanisms, their video settings, relative positioning, and may include power scheme data. When a monitor is plugged into or unplugged from a computer system, a monitor manager component is notified and determines the current configuration, such as based on monitor identifiers. The current configuration is searched against persisted monitor configurations seeking a match. If previous monitor configuration data is found, the previous monitor configuration is applied. If not an exact match, configuration data is constructed based on similar configuration data that is persisted, or by querying for capabilities and iterating as necessary to find a video mode that the video card and monitor can use.

Claims

1. In a computer system capable of displaying information on a plurality of display mechanisms, a method for dynamically configuring the display settings of the system to customize the system to the combination of the plurality of display mechanisms, the method comprising:

in a computer system having a first display mechanism connected thereto, receiving an indication that a second display mechanism has been connected to the computer system;

evaluating information received from the second display mechanism to identify the second display mechanism;

using the identity of the second display mechanism, searching a data structure for an entry indicating that the second display mechanism has been previously connected to the computer system concurrently with the first display mechanism, wherein the data structure contains entries corresponding to previous combinations of display mechanisms that have concurrently been connected to the computer system;

upon failing to locate an entry corresponding to the combination of the first and second display mechanisms, searching the data structure for an entry corresponding to a combination of display mechanisms that is similar to the combination of the first and second display mechanisms;

upon locating an entry corresponding to a similar combination, using the entry to access configuration data corresponding to the similar combination; and

applying the configuration data to the combination of the first and second display mechanisms.

2. The method of claim 1 wherein the information received from the second display mechanism is received by querying the second display mechanism for capability information.

3. The method of claim 2 further comprising, testing settings based on the capability information with a currently installed video card.

4. The method of claim 3 wherein the test does not succeed, and further comprising, iterating to test different settings.

5. The method of claim 1 wherein the information received from the second display mechanism comprises an identifier.

6. The method of claim 1 wherein applying the configuration data to the combination of the first and second display mechanism comprises applying a set of video-related settings to the combination, the set containing at least one setting from among:

a resolution setting, a refresh rate setting, a color depth setting, an orientation setting, a brightness setting, a contrast setting, a video head state setting, and/or a dots per inch setting.

7. The method of claim 1 further comprising, creating a new entry in the data structure corresponding to the combination of the first and second display mechanisms.

8. The method of claim 1 wherein searching the data structure for an entry corresponding to a combination of display mechanisms that is similar comprises comparing the Extended Display Identification Data of each display mechanism in the combination to the Extended Display Identification Data of each display mechanisms of a combination that has been previously stored in the data structure.

9. The method of claim 1 wherein the similar combination is a combination in which the first display mechanism was most recently used.

10. The method of claim 1 wherein searching the data structure for an entry corresponding to a combination of display mechanisms that is similar comprises comparing capabilities of each monitor in the combination.

11. The method of claim 1 wherein searching the data structure for an entry corresponding to a combination of display mechanisms that is similar comprises searching the data structure for a combination that includes the first and second display mechanism in addition to one or more other display mechanisms.

12. At least one computer-readable storage medium having stored computer-executable instructions, which when executed perform a method for dynamically configuring the display settings of a computer system to customize the system to the combination of the plurality of display mechanisms, the method comprising:

in a computer system having a first display mechanism connected thereto, receiving an indication that a second display mechanism has been connected to the computer system;

evaluating information received from the second display mechanism to identify the second display mechanism;

using the identity of the second display mechanism, searching a data structure for an entry indicating that the second display mechanism has been previously connected to the computer system concurrently with the first display mechanism, wherein the data structure contains entries corresponding to previous combinations of display mechanisms that have concurrently been connected to the computer system;

upon failing to locate an entry corresponding to the combination of the first and second display mechanisms, searching the data structure for an entry corresponding to a combination of display mechanisms that is similar to the combination of the first and second display mechanisms;

upon locating an entry corresponding to a similar combination, using the entry to access configuration data corresponding to the similar combination; and

applying the configuration data to the combination of the first and second display mechanisms.

13. The computer-readable storage medium of claim 12 further comprising persisting the configuration data, wherein persisting the configuration data includes writing information to a persistent store, the information including at least one setting of a set of display mechanism settings, the set containing:
