Example one

Fig. 3 is a flowchart of a first embodiment of a method for setting screen projection display parameters according to the present invention. A screen projection display parameter setting method comprises the following steps:

s1, when the screen projection equipment is connected with the screen projection display through the screen projection line, acquiring the extended display identification data of the screen projection display, and simultaneously detecting whether a recording file for recording the screen projection display parameters is empty.

And S2, if the recording file is empty, selecting one screen projection display parameter from the extended display identification data as the current setting parameter of the screen projection display, and recording the setting parameter and the equipment name of the screen projection display in the recording file in an associated manner.

And S3, if the recording file is not empty, detecting whether the device name is matched in the recording file, and if the device name is matched, detecting whether screen projection display parameters corresponding to the device name are called in the recording file.

And S4, if the screen projection display parameters corresponding to the equipment name are called, taking the screen projection display parameters as the setting parameters, and if the screen projection display parameters corresponding to the equipment name are not called, selecting one screen projection display parameter from the extended display identification data as the setting parameters.

Optionally, in this embodiment, for a memory control requirement that is not realized in the prior art that multiple resolution displays are switched to be used in a screen projection process, and a corresponding solution for screen projection memory control is not proposed, a screen projection design scheme with a memory function is proposed in this embodiment, a screen projection mode may be HDMI/DP, specifically, parameters such as resolution, refresh rate, and device name set when a user uses different display devices are recorded, when the device is inserted next time, the set parameter is retrieved in a stored database, and video data or other display data of a screen projection device such as a mobile phone is displayed according to the extracted parameters or similar parameters according to an EDID information result obtained by comparing the mobile phone at this time.

Optionally, in this embodiment, taking a case that a mobile phone is dropped to an external display as an example, before the dropping is started, the mobile phone establishes a dropping connection state with the display through a patch cord, for example, a TypeC to HDMI/DP conversion, and then the mobile phone acquires EDID information related to the display, and at this time, all display parameter mode information supported by the display is analyzed and stored in a bidirectional list in this embodiment, for example, (connector- > modes).

Optionally, in this embodiment, before setting the specific screen projection parameters, first, a record file for recording the screen projection parameters set by the user is opened, where the record file includes information such as a resolution, a refresh rate, and a device name of the display.

Optionally, in this embodiment, if it is detected that the record file is empty, it indicates that the user sets the screen projection parameters for the first time, at this time, the control flow of this embodiment switches to a preset preference algorithm, and first, an optimal screen projection parameter is displayed, and if the user is not satisfied, the selected parameter is recorded in the record file after the user selects the parameter preferred by the user through the UI interface setting, and is displayed by screen projection again according to the parameter set by the user.

Optionally, in this embodiment, if it is detected that the record file is not empty, first, according to the device name obtained from the EDID information, whether parameter information matching the device name exists is retrieved from the record file.

Optionally, in this embodiment, if it is detected that the record file does not have a matching device name, it is determined that the record file is a new display device, or a capture card device, and similarly, according to the above-mentioned preference algorithm, in this embodiment, first, an optimal screen projection parameter is selected, and if the user is not satisfied, a new parameter is set through the UI and then stored. The new parameters are subjected to data processing and are reserved at the end of the recording file in a uniform format, so that a screen projection picture or video can be displayed according to the display parameters newly set by a user.

Optionally, in this embodiment, if it is detected that the record file has a matching device name, it is necessary to check, in a bidirectional mode list parsed according to the EDID, whether a parameter set by the user last time is in the bidirectional mode list this time.

Alternatively, in this embodiment, if the parameters last set by the user are in the mode bidirectional list this time, the parameters last set by the user are displayed in a screen projection mode.

Alternatively, in this embodiment, if the parameters last set by the user are not in the bidirectional mode list this time, it is determined that the user may have replaced a new docking station, or line, or acquisition card, etc., but the display has not been replaced, thereby resulting in no parameters last set in the mode parsed this time being acquired.

Optionally, in this embodiment, in order not to force that the screen projection fails due to the parameter set by the user last time, corresponding fault-tolerant processing is performed in this embodiment, that is, first, the process is switched to the preference algorithm of the display parameter, an optimal screen projection parameter is selected, the user can reset the screen projection parameter according to the UI and update the screen projection parameter that is retained in the record file before, and finally, the screen projection is displayed by using the newly set screen projection parameter. In this embodiment, after the screen projection is completed, the screen projection line is unplugged, the EDID information is cleared, and the recording file is closed.

Optionally, in this embodiment, by using the above detection method for recording files, a scheme that an application layer creates files to store setting parameters of a user is bypassed, and files are read and written by a bottom driver to implement recording and consulting functions of parameters, so that the technical difficulty that previously recorded file information cannot be acquired in a startup scene of a screen-projection line is solved.

Optionally, in this embodiment, the obtained display data format is prevented from being irregular, and the stored parameter data is unified through data processing, so that the efficiency of subsequent retrieval is improved.

Optionally, in this embodiment, a fault tolerance mechanism is added, so as to prevent the problem that the screen projection is unsuccessful due to the inconsistency of the EDID information acquired by the mobile phone caused by the compatibility among the screen projection line, the acquisition card and the display.

The method has the advantages that when the screen projection equipment is connected with the screen projection display through the screen projection line, the extended display identification data of the screen projection display is obtained, and meanwhile, whether a recording file for recording screen projection display parameters is empty is detected; if the recording file is empty, selecting one screen projection display parameter from the extended display identification data as the current setting parameter of the screen projection display, and recording the setting parameter and the equipment name of the screen projection display in the recording file in an associated manner; if the recording file is not empty, detecting whether the equipment name is matched in the recording file, and if the equipment name is matched, detecting whether screen projection display parameters corresponding to the equipment name are called in the recording file; and if the screen projection display parameters corresponding to the equipment name are called, taking the screen projection display parameters as the setting parameters, and if the screen projection display parameters corresponding to the equipment name are not called, selecting one screen projection display parameter from the extended display identification data as the setting parameters.
