The working mode of the signal ID transmission module is as follows: the display main control chip transmits the signal ID to the upper layer desktop control software through a related protocol, and a transmission channel can pass through a serial port (serial port protocol) and also can pass through a signal line (DDC protocol).
Display ProductCode ID extraction Module: the upper layer desktop control software searches all screens connected to the host system by calling the AllScreens attribute of the Screen class (for example, if one display has 3 signal channels which are respectively connected to 3 output channels of the host display card, 3 screens can be searched). Then for each Screen returned, the product code ID, start coordinates (X, Y), resolution (Width, Height) of the current Screen are obtained using WmiMonitorID in Wmi.
An ID matching module: the product code ID parameter in the EDID of the multiple channels of the display is differentiated, for example, the channel 1 is set to JUS0001, the channel 2 is set to JUS0002, and the channel 3 is set to JUS0003.. the number of the last two bits of the parameter is consistent with the ID in "each channel of the display will use different IDs for differentiation", for example, the signal ID is 1 when the signal is cut into the channel 1 (i.e., the first signal channel interface 1). The upper layer desktop control software acquires the signal ID from the display main control chip through a relevant protocol. When the upper-layer desktop control software executes the returned Screen, acquiring the ProductCode ID of the current Screen by using the WmiMonitorID in Wmi, extracting the last two digits from the ProductCode ID, converting the two digits into integers, matching the integers with the signal ID acquired from the display main control chip, and when the matching is successful, indicating that the currently traversed Screen is a display Screen and correspondingly acquiring the initial coordinate and the resolution of the current display Screen.

The specific value of the mouse coordinate can be set as the center point of the current display screen or any other point of the current screen, and the specific operation is to reset the value of the Position attribute of the Cursor.
The upper layer desktop control software retrieves all screens connected to the host system by calling the AllScreens attribute of the Screen class, and the patent herein has no limit on the number of screens, i.e., how many interfaces the display has.
A method for controlling a display to automatically display a mouse on a current screen after signal switching comprises the following steps: the current signal ID identifies the module. Each channel of the display can be distinguished by different IDs, after the menu control chip of the display captures signal switching information, the current display signal ID is transmitted to the display main control chip, and the display main control chip identifies the current signal ID; and a signal ID transmission module. The display main control chip transmits a signal ID to upper desktop control software through a serial port line or a signal line based on a related serial port protocol or a DDC protocol; and a display ProductCode ID extraction module. The upper layer desktop control software searches all screens connected to the system by calling the AllScreens attribute of the Screen class (for example, if one display has 3 signal channels which are respectively connected to 3 output channels of the host display card, 3 screens can be searched). Then for each returned screen, acquiring the ProductCodeID, the starting coordinate (X, Y) and the resolution (Width, Height) of the current screen by using WmiMonitorID in Wmi; and an ID matching module. The ProductCode ID parameter in EDID of a multiplexed channel of a display is differentiated, for example, channel 1 is set to JUS0001, channel 2 is set to JUS0002, and channel 3 is set to JUS0003. The number of the last two bits of the parameter is consistent with the ID used for protocol identification of each channel. For example, if the signal ID of the channel 1 is 1, the ProductCode ID in the EDID of the channel 1 is JUS0001, and the signal ID of the channel 2 is 2, the ProductCode ID in the EDID of the channel 2 is JUS 0002. When the upper-layer desktop control software is executed, acquiring the ProductCode ID of the current screen by using WmiMonitorID in Wmi for each returned screen, extracting the last two digits from the ProductCode ID, converting the two digits into integers, matching the integers with the signal ID acquired from the main control chip, and when the matching is successful, indicating that the currently traversed screen is a display screen and correspondingly acquiring the initial coordinate and the resolution of the current display screen; and a mouse position resetting module.

Fig. 1 is a block diagram of a method for automatically displaying a mouse on a current screen after controlling a display to perform signal switching according to the present invention. As shown in fig. 1, the display includes 1 menu control chip, 1 display main control chip, 3 signal channel interfaces (as shown in 1, 2, and 3 in fig. 1, the technical solution itself has no limitation on the number of interfaces, and 3 interfaces are used for example here), and 1 serial port. 3 signal channel interfaces (channels for short, signal channels) are respectively burned with different EDIDs (extended display identification data), two bits behind the product code ID (product number) in the EDIDs are given different numbers, and the respective numbers are consistent with the identification ID of each channel protocol; the host computer comprises 3 signal output interfaces, 1 USB port and 1 upper layer desktop control software. The 3 signal output interfaces of the host are respectively connected to the 3 signal channel interfaces of the display through signal lines, at this time, the host recognizes 3 screens (as shown in fig. 2), and the display signals of the display can be switched between channels 1 and 3 (i.e., 1 the first signal channel interface, 2 the second signal channel interface, and 3 the third signal channel interface), or can be switched between a multi-screen mode and a single-screen mode. And the USB port of the host is connected with the serial port of the display through a USB-to-serial port line and is used for communication between the display main control chip and the upper desktop control software. For example, switching between channels 1 and 2, the original state is that the display displays the signal as channel 1, and the mouse is positioned on the screen 1. When the display signal switches to channel 2 through the display menu, the mouse position is still on screen 1. The menu control chip will recognize the change of the channel and send the ID of the current (i.e., switched) signal to the display main control chip. The display main control chip transmits the signal ID to upper desktop control software through a USB-to-serial port line based on a corresponding serial port protocol. The upper layer desktop control software retrieves 3 screens connected to the system by calling the AllScreens attribute of the Screen class, and sequentially acquires the ProductCodeID, the start coordinate (X, Y), and the resolution (Width, Height) of each Screen by using the WmiMonitorID in Wmi. The last two digits are extracted from the ProductCodeID and converted into integers, the integers are matched with the signal ID acquired from the display main control chip, when the matching is successful, the currently traversed screen is indicated as a display screen, the initial coordinate and the resolution of the current display screen can be acquired correspondingly, then the coordinate range of the current display screen is calculated, the mouse coordinate is reset into the range of the current display screen by resetting the Position attribute value of the Cursor, and therefore the mouse can be automatically displayed on the current screen.
