Abstract

Claims (43)

1. A system comprising:

a computing device;

a monitor; and

a human interface device;

wherein the system is configured to perform a method for selectively controlling the monitor's on-screen display (OSD) with the human interface device, the method comprising:

prior to detecting an OSD command, providing input from the human interface device to the computing device;

while the input from the human interface device is being provided to the computing device, detecting the OSD command; and

in response to detecting the OSD command, ceasing to provide the input from the human interface device to the computing device and commencing providing the input from the human interface device to the monitor to thereby cause the input to control the monitor's OSD.

2. The system of claim 1 , wherein a microcontroller of the human interface device is configured to perform the method.

3. The system of claim 1 , wherein a filter driver on the monitor is configured to perform the method.

4. The system of claim 1 , wherein the monitor includes a filter driver that is configured to evaluate the input from the human interface device that is provided to the monitor to determine whether the input includes any secure commands, wherein the filter driver routes any input that is a secure command to an embedded controller of the monitor and routes any input that is not a secure command to a scalar of the monitor.

5. The system of claim 1 , wherein detecting the OSD command comprises detecting the OSD command in the input from the human interface device.

6. The system of claim 1 , wherein the method further comprises:

again detecting the OSD command; and

in response to again detecting the OSD command, ceasing to provide the input from the human interface device to the monitor and commencing providing the input from the human interface device to the computing device.

7. A method for selectively controlling a monitor's on-screen display (OSD) with a human interface device, the method comprising:

prior to detecting an OSD command, providing input from the human interface device to a computing device to which the monitor is connected;

while the input from the human interface device is being provided to the computing device, detecting the OSD command; and

in response to detecting the OSD command, ceasing to provide the input from the human interface device to the computing device and commencing providing the input from the human interface device to the monitor to thereby cause the input to control the monitor's OSD.

8. The method of claim 7 , wherein detecting the OSD command comprises detecting the OSD command in the input from the human interface device.

9. The method of claim 7 , further comprising:

again detecting the OSD command; and

in response to again detecting the OSD command, ceasing to provide the input from the human interface device to the monitor and commencing providing the input from the human interface device to the computing device.

10. The method of claim 7 , wherein a microcontroller of the human interface device provides the input from the human interface device to the computing device and to the monitor.

11. The method of claim 7 , wherein a filter driver on the monitor provides the input from the human interface device to the computing device and to the monitor.

12. The method of claim 7 , wherein providing the input from the human interface device to the monitor comprises providing the input from the human interface device to a scalar of the monitor.

13. The method of claim 7 , wherein the human interface device is a keyboard or a mouse.

14. The method of claim 7 , further comprising:

evaluating the input from the human interface device that is provided to the monitor to determine whether the input includes any secure commands;

for any input that is a secure command, routing the input to an embedded controller of the monitor; and

for any input that is not a secure command, routing the input to a scalar of the monitor.

15. A method for selectively controlling a monitor's on-screen display (OSD) with a human interface device of a computing device, the method comprising:

evaluating input from the human interface device to detect occurrences of an OSD command;

in response to an occurrence of the OSD command, toggling an OSD mode;

for input that is not the OSD command, sending the input to the computing device when the OSD mode is off and sending the input to the monitor when the OSD mode is on.

16. The method of claim 15 , wherein the method is performed by a microcontroller of the human interface device.

17. The method of claim 15 , further comprising:

evaluating the input that is sent to the monitor; and

when a secure command is detected in the input that is sent to the monitor, routing the secure command to the computing device.

18. The method of claim 17 , wherein a microcontroller of the human interface device sends the input to the computing device and to the monitor, and wherein a filter driver on the monitor evaluates the input that is sent to the monitor and routes the secure commands to the computing device.

19. The method of claim 15 , wherein evaluating input from the human interface device comprises determining which keys of a keyboard or which buttons of a mouse have been pressed.

20. The method of claim 15 , further comprising:

in response to the occurrence of the OSD command, notifying a scalar of the monitor of the occurrence of the OSD command to thereby cause the scalar to show or hide the OSD.
