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.
Your computer has the following USB ports:
• 1 USB 3.0 upstream - bottom
• 2 USB 2.0 downstream - bottom
• 2 USB 3.0 downstream - left side
Power Charging Port - the ports with battery icon supports fast current
charging capability if the device is BC 1.2 compatible.
NOTE: The monitor’s USB ports work only when the monitor is on or in the power
save mode. 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: http://www.dell.com/support/monitors.
