COMPUTER AND METHOD FOR CONTROLLING EXTERNAL DISPLAY DEVICE
First Claim
1. A computer adapted for coupling with an external display device, comprising:
- a hardware layer module comprising a plurality of interface ports, a preset interface port of the plurality of interface ports adapted for coupling with the external display device;
a driver layer module coupled to the hardware layer module, when the external display device is coupled to the hardware layer module via the preset interface port, the driver layer module outputs a notify message and controls the hardware layer module to read hardware information of the external display device; and
an application layer module coupled to the driver module, for reading the hardware information from the hardware layer module via the driver layer module as receiving the notify message, and controlling the driver layer module to provide multiple displaying modes to the hardware layer module according to the hardware information, so as to enable the external display device to display a video in one of the displaying modes.

Abstract
A computer has a hardware layer module, a driver layer module, and an application layer module. The hardware layer module has a number of interface ports, and a preset interface port of the interface ports is coupled with the external display device. When the external display device is coupled to the hardware layer module via the preset interface port, the driver layer module outputs a notify message to the application layer module and controls the hardware layer module to read hardware information of the external display device. In addition, upon receiving the notify message, the application layer module can read the hardware information from the hardware layer module via the driver layer module and control the driver layer module to provide multiple displaying modes to the hardware layer module according to the hardware information. Thus, the external display device is enabled to display a video in a suitable displaying mode.
