MST connection
No sound can be heard from the built-in speakers. (selected models only)
• Check whether the desired cable to input audio signals is properly connected. See Connect
the headphone. on page 17 for details.
• Increase the volume (volume may be muted or too low).
• Remove your headphone and/or external speakers. (If they are connected to the monitor,
the built-in speakers are automatically muted.)
No sound can be heard from the connected external speakers.
• Remove your headphone (if the headphone is connected to the monitor).
• Check whether the headphone jack is properly connected.
• If the external speakers are USB-powered, check whether the USB connection is OK.
• Increase the volume (volume may be muted or too low) on the external speakers.
The built-in microphone does not respond when the monitor is connected to a PC.
• Check if the certified USB-C™ cable with signal transmission and power delivery functions is
properly connected.
• Turn on the microphone by pressing the MIC key. See Basic menu operation on page 32 for
the location of the key.
• Increase the MIC volume from the Audio menu. See Audio menu on page 47 for more
information.
The light sensor of the monitor does not work well.
The light sensor is located at the front bottom of the monitor. Please check:
• If you have removed the sensor protection sticker.
• If the Bright Intelligence function is set to ON. Check
Eye Care > Bright Intelligence.
• If there are any obstacles in front of the sensor that keep
the sensor from detecting the light properly.
• If there are any objects or clothing in bright colors in front
of the sensor. Bright colors (especially white and fluorescent
colors) reflect light and the sensor cannot detect the main
light sources.
The MST function does not work.
Make sure ON is selected under System > MST.
• Make sure the graphic card on your computer supports DP 1.4 for MST.
• The compatibility of each computer varies by hardware and/or software. You may need to go
through all the cables, specifications and settings to ensure that your system supports MST. If
your computer is a Mac, try with a Windows system. MST is available on a Mac OS via
Thunderbolt connection only.
