Attention:
The L28u-35 uses natural low blue light technology to protect your eyes by not only maintaining picture
quality but also reducing harmful blue light at 6500K color temperature. If you cannot confirm whether the
monitor is already in low blue light mode, you can perform the Restore Factory Settings operation in the
OSD Item Menu Settings → Reset All Settings.
This section describes the functions of the user controls used to adjust the display
image.
When On Screen Display (OSD) is not displayed, you can use direct access
controls.
