Adjusting Low Blue Light Mode
Decreasing the blue light emitted by the display reduces the blue light exposure to your eyes. This monitor
allows you to select a setting to reduce blue light output and create a more relaxing and less stimulating
image while you read content on the screen.
To adjust the blue light output from the display:
1. Press the Viewing Mode button.
2. Select a setting:
● Low Blue Light: Reduces blue light for improved eye comfort
● Night: Adjusts to the lowest blue light and reduces the impact on sleep
● Reading: Optimizes blue light and brightness for indoor viewing
● HP Enhance +
● Multimedia
● Photo
● Custom
3. Select Save and Return to save your setting and close the Viewing Mode menu. Select Cancel if you
don’t want to save the setting.
4. Select Exit from the Main menu.

Using Auto-Sleep Mode
The monitor supports an OSD option called Auto-Sleep Mode that allows you to enable or disable a reduced
power state for the display. When Auto-Sleep Mode is enabled (enabled by default), the monitor will enter a
reduced power state when the host PC signals low power mode (absence of either horizontal or vertical sync
signal).
Upon entering this reduced power state (sleep mode), the monitor screen is blanked, the backlight is turned
off, and the power light turns amber. The monitor draws less than 0.5 W of power when in this reduced power
state. The monitor will wake from sleep mode when the host PC sends an active signal to the monitor (for
example, if you activate the mouse or keyboard).
You can disable Auto-Sleep Mode in the OSD. Press the menu button to open the OSD. In the OSD select Power
Control, select Auto-Sleep Mode, and then select Off.
