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 Picture
Advanced
> B. I. +.
• 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.
No video or audio output from the laptop with USB-C™ connection.
Check the cable connections and menu settings in the following order.
• Check if the USB-C™ cable has been connected to the monitor and the laptop properly. See
Connect the PC video cable. on page 11 for more information.
• Check if the input source has been selected to USB-C on Display > Input.
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 Working with HDR technology on page 27 to check if a supported player,
content, and the certified cable are used.
