Abstract
A device is interposed between a first device display port and a second device display port. The device passes through signals provided from the first device display port to the second device display port except when predefined signals are detected. For the predefined signals, the device translates the predefined signals received from the first device display port into different signals that are provided to the second device display port.
Claims10
A method, comprising:
- receiving, by a display sniffer device, data signals associated with a first display integrated into a computer and provided from the computer to an independent display device;
- identifying, by the display sniffer device, predefined signals that are embedded with the data signals provided from the computer;
- mapping, by the display sniffer device, the predefined signals to different signals;
- providing, by the display sniffer device, the different signals to the independent display device;
- and
- controlling, by the display sniffer device, backlights of the independent display device through the providing of the different signals with existing programming logic associated with and installed on the computer and the independent display device remaining unchanged when controlling the backlights, wherein the independent display device lacks backlight logic to independently turn on and off the backlights when the independent display device is being used as a second display for the computer, and wherein an only mechanism of the independent display device to control the backlights is through on chip logic when the independent display device is used as a primary display device, and wherein the sniffer display device provides the different signals to the independent display device as backlight control commands recognized by the on chip logic of the independent display device to the control the backlights.

A method, comprising:
- detecting, by a display sniffer device, predefined signals being sent between a first display integrated into a computer to an independent display device having backlights;
- obtaining, by the display sniffer device, different signals in response to detection of the predefined signals;
- providing, by the display sniffer device, the different signals to the independent display device;
- and
- controlling, by the display sniffer device, a backlight of the independent display device with the providing utilizing existing programming logic installed on the computer and the independent display device, wherein the existing programming logic remains unchanged when controlling the backlight, wherein the independent display device lacks backlight logic to independently turn on and off the backlight when the independent display device is being used as a second display for the computer, and wherein an only mechanism of the independent display device to control the backlights is through on chip logic when the independent display device is used as a primary display device of the computer, and wherein the sniffer display device provides the different signals to the independent display device as backlight control commands recognized by the on chip logic of the independent display device to the control the backlight.
