[0104] Figure 4 The following is a flow chart of the expansion dock provided by the present invention outputting image data through a display device, as shown in FIG. Figure 4 As shown, the process may include the following steps:

[0105] Step 401: Initialize the display port configuration data (DPCD).

[0106] For example, DPCP initialization may be an operation performed after the processor 102 of the docking station 100 detects that the docking station 100 is connected to the electronic device and the display screen is extended.

[0107] Exemplarily, DPCP initialization may include the processor 102 acquiring the format of a DPCD signal output by the electronic device, the type of DPCD protocol, etc.; wherein the DPCD signal may be the connection status data in the aforementioned embodiment.

[0108] Step 402: Initialize the High Definition Multimedia Interface (HDMI).

[0109] Exemplarily, HDMI initialization may include the processor 102 acquiring display parameters of the extended display through the second transmission module.

[0110] For example, when the expansion dock is electrically connected to the electronic device and the extended display screen at the same time, steps 401 and 402 can be executed in parallel, and the execution order can also be adjusted successively, which is not limited in the present invention.

[0111] Step 403: Link training.

[0112] Exemplarily, this step is used for the processor 102 to confirm the validity of the DP signal sent by the electronic device based on the DPCD protocol, and is also used for the processor 102 to confirm the display parameters obtained by HDMI initialization.

[0113] Step 404: Start the On-Screen Display (OSD) function.

[0114] Exemplarily, after the OSD function is activated, the processor 102 may convert the DP signal it receives into image data that matches the display parameters of the extended display screen.

[0115] Step 405: Enable image output and output the image.

[0116] Exemplarily, after generating the image data, the processor 102 may enable image output and send the image data to the extended display screen so that the extended display screen outputs the image data.

[0117] Through the above process, the processor of the expansion dock can obtain the DPCD signal of the electronic device and the HDMI-related display parameters of the extended display in real time, and perform targeted conversion of the DP signal based on the display parameters, thereby improving the matching degree between the image data and the display parameters of the extended display, and increasing the probability of stable display of the image data.
