Hello, about this configuration should be like this
1 -> second
2 -> first
or something like this
1 -> second
2 -> the second
Regarding the Presentation Only mode, if this mode is used, the device will not think that the screen display in this mode needs to be controlled. That is to say, the device will think that there is only one screen that can control the output content at present, so whether you choose "first" or "second", the display on the screen will be in single-screen mode.
Regarding the function you want to achieve, the complete application code has been given in the macro code example of the device.
The exact location is as shown in the picture
