Abstract

The current technology and implementation of configuring a 2nd or auxiliary monitor requires that the user manually set the logical location of the second (or nth) monitor in a multi-monitor setup. For instance, if a second monitor is used at work on the left side of the laptop, while the second monitor at home is found on the right side of the laptop, the logical location must be changed each time the user moves from office to home, or from home to office. Disclosed is a method by which system software can detect the approximate location of the 2nd or auxiliary monitor(s), and set the logical location automatically.

Proximity detection of Auxiliary Monitors Automates Multiple Monitor Arrangement

This automation is accomplished by the detection of two very small beacon signals generated in the auxiliary monitor(s), one on the auxiliary monitor's left side and one on its right side. The signal strength difference between them provides enough information to determine approximately where the auxiliary monitor is located. The receiver is located in the primary monitor. Four transmitters, one at each quadrant of the auxiliary monitor, can be used to improve the vertical location accuracy. Two receivers, one in each upper or lower half of the primary monitor, can also be used to improve the vertical location accuracy.

The auxiliary monitor sends the beacon when prompted by the system thru a digital video interface. Therefore, in a multiple monitor arrangement, the individual monitors would be prompted sequentially, such that their individual locations can be determined independently. The receiver could be an existing RF (radio frequency) subsystem, such as for wireless LAN (local area network) or Bluetooth*, but re-tasked momentarily to serve the purpose of auxiliary monitor location. A general purpose monitor would include both transmitters and receiver. The integrated monitor in a laptop would require only the receiver, which is native to most laptops already....
