Using Auto-Sleep Mode
The monitor supports an on-screen display (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, the monitor
enters a reduced power state when the host computer signals low power mode, absence of either horizontal
or vertical sync signal. Auto-Sleep Mode is enabled by default.
Upon entering this reduced power state (sleep mode), the monitor screen is blanked, the backlight is turned
o, and the power light indicator turns amber. The monitor draws less than 0.5 W of power when in this
reduced power state. The monitor wakes from the sleep mode when the host device sends an active signal to
the monitor (for example, if you activate the mouse or keyboard).
To disable Auto-Sleep Mode:
1. Press the Menu button to open the OSD.
2. In the OSD menu, select Power Control, select Auto-Sleep Mode, and then select O.
Changing the Power Mode setting
When in sleep mode, to comply with international power standards, the monitor default setting is Power
Saver mode. If your display supports Performance mode, then to keep the USB ports enabled even when the
monitor is in Auto-Sleep Mode, change the Power Mode setting from Power Saver to Performance.
To change the Power Mode setting:
1. Press the Menu button to open the OSD menu.
2. Select Power Control, select Power Mode, and then select Performance.
3. Select Save and close the OSD.
