How can I fix it if the Coding HotKey doesn’t work after I turn on the power?

Please check whether the input signal is correct first, if yes, please follow the steps below; 

1. Please unplug the power cord and try connecting again:

• Plug one end of the power cord into the socket labeled ~ on the rear of the monitor.    
• Plug the other end of the power cord into a power outlet

2. When plugging the power cord, please refrain from touching the
    Coding HotKey and Function Bar.

For more details, please refer to the "5. Connect the power cable" in the user manual.

If the problem persists, please contact BenQ Support.
