Universal Serial Bus (USB)
This section provides 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 1 USB downstream ports.
Your computer has the following USB ports:
• 1 upstream - at rear.
• 2 downstream - 1 at bottom, 1 at rear.
NOTE: The monitor’s USB ports work only when the monitor is on or when the
monitor is on, in Standby Mode. When the monitor is on, in Standby Mode, if the
USB cable (C to C or A to C), is plugged in, the USB ports can work normally.
Otherwise, follow the OSD setting of Other USB Charging, if the setting is “On in
Standby Mode” 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 with its extended display identification data
(EDID) using display data channel (DDC) protocols so that 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 about LCD Monitor Pixel Policy,
see Dell support site at: https://www.dell.com/pixelguidelines.
