Abstract

Disclosed is a method to automatically set the resolution of a computer when attaching a display device. The system performs as follows: 1) The laptop computer is connected to the display device. 2) A popup window appears on the laptop screen offering all resolutions that the display device is able to handle. 3) The laptop computer switches automatically to the optimal offered resolution. This resolution can be the highest resolution offered by the display device. Alternatively, the user is given the list of working resolutions and can make a selection (which triggers automatically the switch to the proper/matching resolution on his or her laptop computer). 4) The user can give the presentation. 5) When the display device is disconnected, the laptop resolution is reset to its original setting (before the projector was connected).

Method to Automatically Set the Screen Resolution of a Computer when Attaching a Display Device
Giving a presentation using a laptop computer has become quite common for most people these days. Unfortunately, many problems are encountered when a laptop computer is attached to a display device like a beamer or projector. In general, the procedure used to connect a computer to a projector can be described as trial and error. The following steps are performed:
1) The laptop computer is connected to the display device (using a video cable).
2) The user presses a certain key combination to activate the video output port. (e.g.: Fn-F7, for many IBM Thinkpad computers) In many cases no output appears due to the fact that the display device is not able to display the high resolution of the laptop computer. Most of time, the projector will display a "no sync" message or something similiarly unhelpful. However, the projector does not communicate its capabilities to the laptop computer.
3) The user is forced to change the resolution of the laptop computer to adapt to the display device capabilities. If no matching resolution is set, no output will be displayed and the procedure of changing resolution on the laptop computer needs to be continued.
4) The user finally finds a resolution that the display device is able to work with. The presentation can begin.
5) After a hopefully successful presentation, the resolution on the laptop computer is set back to its original setting (before the presentation started).

Clearly, this is a very tedious and error-prone procedure. Not knowing the resolutions that the display device is able to work with, forces the user to change and try out one resolution after the other on his or her laptop computer. Not a very pleasant task. Needless to say that people wish for a better solution.

This situation has only sightly improved with the introduction of another software. Giving a presentation results in the following scenario:
1) The laptop computer is connected to the display device.
2) The user presses a certain key combination to activate the video output port. The presentation software appears...
