I had a random no symbol on my external monitor that was being caused by its OSD detecting microphone mute and showing an icon.

This certainly isn’t a fix, but if you try to screenshot the icon and it shows up, you’ll know it’s being drawn by the computer and not the monitor.

Might give you a direction to investigate :)
