No sound can be heard from the built-in speakers.
• 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.)
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
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.
The ECO sensor of the monitor does not work well.
• The ECO sensor is located at the front bottom of the
monitor. Check if there are any obstacles in front of the sensor
that keep the sensor from detecting your presence properly.
• If you have removed the sensor protection sticker.
• The colors and the materials of your clothes may affect the
detection. Adjust the sensor range if needed. See
Sensor
Range on page 49
for more information.
• Adjust the distance between you and the monitor.
If none of the proceeding actions works, it is probably because
the materials of your clothes are unique and cannot be detected by the ECO sensor. Please be
noted that this is neither a manufacturing detect nor is the sensor damaged. You should turn
off the ECO sensor for now in
