Specifically, when the key is pressed, the 14 pin of the GPIO interface of the PD protocol IC (i.e., FL 7102) is triggered, and then FL7102 communicates with the display conversion chip (i.e., PS 186) through the I2C bus to change (also understood as being set) the register of PS186 for controlling the video bandwidth to DP1.2 (i.e., the first transmission channel 202 described above), video bandwidth to 5.4Gbps (i.e., the first bandwidth described above), and support the maximum resolution to 1080p@60hz (i.e., the first resolution described above); after that, FL7102 is reconnected to CC, so that the computer (i.e., the above-mentioned video source device) outputs the video signal (i.e., the DP signal) to PS186 again, and the video display device displays the video of 1080p@60hz. When the key is pressed again, pin 14 of the GPIO interface of FL7102 is triggered again, and FL7102 communicates with PS186 again through the I2C bus to change the register of PS186 for controlling video bandwidth to DP1.4 (i.e. the second transmission channel 203), video bandwidth to 16.2Gbps (i.e. the second bandwidth), and support maximum resolution to 4k@60hz (i.e. the second resolution); after that, FL7102 re-connects CC to make the computer (i.e., the above-mentioned video source device) re-output the video signal (i.e., DP signal) to PS186, so that the video display device displays the video of 4k@60hz. Here, "DP1.2, video bandwidth of 5.4Gbps, support maximum resolution of 1080p@60hz" can be understood as the above-described first mode; "DP1.4, video bandwidth of 16.2Gbps, support maximum resolution of 4k@60hz" can be understood as the above second mode.
