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 standby
mode. If you turn off the monitor and then turn it on, the attached peripherals may
take a few seconds to resume normal functionality.

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.
