If you want to change any parameter or just get its current value you need to follow the same syntax:
displaxservice -a IP_ADRESS --PARAMETER
- IP_ADRESS : is the IP address of the computer the device you want to control is connected. For localhost device connection you should use “127.0.0.1”
- PARAMETER: is the parameter or option you want to change or get its current value
Here you can see how to get the list of parameters for a specific device.
