Using Auto-Sleep Mode; Adjusting Blue Light Output - HP EliteDisplay E24d G4 User Manual

Using Auto-Sleep Mode

The monitor supports an OSD menu option called Auto-Sleep Mode that allows you to enable or disable a
reduced power state for the monitor. When Auto-Sleep Mode is enabled (enabled by default), the monitor
enters a reduced power state when the computer signals low power mode (absence of either horizontal or
vertical sync signal).

and the power light turns amber. The monitor draws less than 0.5 W of power when in this reduced power
state. The monitor wakes from sleep mode when the computer sends an active signal to the monitor (for
