Why can’t I control the input volume, or why do I see the volume control grayed out on Display Pilot 2(mac) for my BenQ monitor?

04-28-2025

The default audio output of MacOS is a Mac built-in speaker.

The volume control panel of Display Pilot 2 is dedicated to the BenQ built-in speaker; therefore, it only works when users change the audio output to the BenQ built-in speaker.

You need to change the output audio to the BenQ monitor's built-in speaker by clicking the indicator on the Display Pilot 2 volume control panel.
