[0005] In addition, in the existing graphics card driver, the size of the video memory space will be dynamically allocated according to the connection status of the display screen. When the status of the external display terminal device changes, the driver will dynamically apply for the video memory space of the screen and switch to the default mode , the driver needs to be reconfigured, including reinitialization and connection status changes, resulting in screen flickering during the switching process
After many experiments and tests, during the switching process, all screens will flash black for about 2 to 3 seconds, and then the switching operation is successful, which will affect the operation and observation of multiple screen interfaces at the same time, and each display terminal Cannot be run independently

The invention discloses a method and a computing device for independently displaying a plurality of display terminals, which are suitable for execution in the computing device. The method includes the steps of: initializing multiple sets of attribute parameters, each set of attribute parameters corresponding to a display port; The connection status of each display port is set as successful connection; and, when it is detected that a display terminal is connected to the display port, the attribute parameter of the corresponding display port is updated to the attribute parameter of the connected display terminal.
Description
technical field [0001] The present invention relates to the technical field of computer software, in particular to a method and a computing device for independent display of multiple display terminals. Background technique [0002] At present, during actual use, there are more and more scenarios where a computer uses dual screens or multiple screens to display different interfaces. For example, some large and complex industrial control equipment requires multiple people to coordinate and operate at the same time to control the operation of the equipment, so multiple display control terminals are required, such as screen A, screen B, screen C...such as figure 1 As shown, each operator has his own independent operation display and control interface, and can operate different functions of the equipment simultaneously or independently. In the case of multiple operators operating at the same time, it is necessary to ensure the interactivity of the software interface application ...
