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 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 has been turned on. Check Ergonomics > 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.
There is a message HDR: Emulated showing on the screen.
This means the input content is not HDR-compatible and the monitor is in HDR-emulated
mode. Refer to Working with HDR technology on page 33 to check if a supported player,
content, and the certified cable are used.
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.
