Power Management Modes

If you have VESA's DPM™ compliance display 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:

U2412M

VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption

Normal operation Active Active Active Blue 72 W (maximum) **
Active-off mode Inactive Inactive Blanked Amber Less than 0.5 W

Switch off - - - Off Less than 0.5 W
The OSD will only function in the normal operation mode. When any button is pressed in Active-off mode, one of the following messages will be displayed:

Activate the computer and the monitor to gain access to the OSD.

29 W (typical)

NOTE: This monitor is ENERGY STAR®-compliant.

* Zero power consumption in OFF mode can only be achieved by disconnecting the main cable from the monitor.
** Maximum power consumption with max luminance, Dell Soundbar, and USB active.

Plug and Play Capability

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 system 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

NOTE: USB 2.0 functionality requires a USB 2.0-capable computer.
NOTE: The monitor's USB interface works only when the monitor is on or in 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.

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 Dell Monitor Quality and Pixel Policy, see Dell Support site at: support.dell.com.

Maintenance Guidelines

Cleaning Your Monitor

WARNING: Read and follow the safety instructions before cleaning the monitor.
WARNING: Before cleaning the monitor, unplug the monitor power cable from the electrical outlet.

For best practices, follow the instructions in the list below while unpacking, cleaning, or handling your monitor:

To clean your antistatic screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the antistatic coating. Do
not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.
Use a lightly-dampened, warm cloth to clean the monitor. Avoid using detergent of any kind as some detergents leave a milky film on the monitor.
If you notice white powder when you unpack your monitor, wipe it off with a cloth.
Handle your monitor with care as a darker-colored monitor may scratch and show white scuff marks more than a lighter-colored monitor.
To help maintain the best image quality on your monitor, use a dynamically changing screen saver and turn off your monitor when not in use.
