Power Management Modes

If you have VESA’s DPM-compliant video card or software installed in your PC, the monitor can automatically reduce its power consumption when not in use. This is referred to as power save mode*. If the computer detects input from the keyboard, mouse, or other input devices, the monitor automatically resumes functioning. The following table shows the power consumption and signaling of this automatic power saving feature.

Universal Serial Bus (USB)

This section gives you information about the USB ports available on your monitor.

NOTE: Up to 2 A on USB downstream port (port with battery icon) with BC 1.2

compliance devices; up to 0.9 A on the other 2 USB downstream ports. Up to 3 A on USB Type-C downstream port (port with icon) with 3 A compliance devices.

Your computer has the following USB ports:

• 4 downstream - 2 at left side, 2 at bottom

Power Charging Port - the ports with battery icon supports fast current charging capability if the device is BC 1.2 compatible. The USB Type-C downstream port with icon supports fast current charging capability if the device is 3 A compatible.

NOTE: The monitor’s USB ports work only when the monitor is on or in the power save

mode. In power save mode, if the USB cable (Type-C to Type-C) is plugged in, the USB ports can work normally. Otherwise, follow the OSD setting of USB, if the setting is “On During Standby” then USB work normally, otherwise USB is disabled. If you turn off the monitor and then turn it on, the attached peripherals may take a few seconds to resume normal functionality.
