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.

20 | About Your Monitor
Plug-and-Play
You can install the monitor in any Plug-and-Play-compatible system. The monitor
automatically provides the computer system with its extended display identification data
(EDID) using display data channel (DDC) protocols so the computer can configure itself
and optimize the monitor settings. Most monitor installations are automatic; you can select
different settings if desired. For more information about changing the monitor settings, see
Operating the Monitor.
LCD Monitor Quality and Pixel Policy
During the LCD monitor manufacturing process, it is not uncommon for one or more pixels
to become fixed in an unchanging state which are hard to see and do not affect the display
quality or usability. For more information on LCD Monitor Pixel Policy, see Dell support site
at: www.dell.com/support/monitors.
