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.

Power Consumption P_on	19.9 W
Total Energy Consumption (TEC)	64.3 kWh

The OSD operates only in the normal operation mode. If you press any button in the active-off mode, the following message is displayed:

Dell UltraSharp 24/27 Monitor No DP signal from your device. Press any key on the keyboard or move the mouse or wake it up. If there is no display, press the monitor button again to select the correct input source. U2419HC/U2719DC

*Zero power consumption in OFF mode can only be achieved by disconnecting the AC mains cable from the monitor.
**Maximum power consumption with maximum luminance, and USB active.

This document is informational only and reflects laboratory performance. Your product may perform differently, depending on the software, components and peripherals you ordered and shall have no obligation to update such information. Accordingly, the customer should not rely upon this information in making decisions about electrical tolerances or otherwise. No warranty as to accuracy or completeness is expressed or implied.

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

NOTE: This monitor is ENERGY STAR certified.

This product qualifies for ENERGY STAR in the factory default settings which can be restored by “Factory Reset” function in the OSD menu. Changing the factory default settings or enabling other features may increase power consumption that could exceed the ENERGY STAR specified limit.

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:

• 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.

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.

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.

Attaching the Stand

NOTE: The stand riser and stand base are detached when the monitor is shipped from the factory.

NOTE: The procedure below is applicable for the default stand. If you purchased any other stand, see the documentation shipped with the stand to set it up.

CAUTION: Place monitor of a flat, clean, and soft surface to avoid scratching the display panel.

Diagram illustrating the process of device mounting, showing steps from disassembly to assembly with orange arrows indicating rotation.

To attach the monitor stand:

1 Align the stand base protruded blocks to the matching slot on the stand.
2 Insert the stand base blocks fully into the stand slot.
3 Lift the screw handle and turn the screw clockwise.
4 After fully tightening the screw, fold the screw handle flat within the recess.

Diagram showing a computer monitor with an open lid and internal components, before and after disassembly (no text or symbols present)

1 Remove the monitor protective cover and place the monitor with its front facing downward on it.

Maintenance Guidelines

Cleaning Your Monitor

WARNING: Before cleaning the monitor, unplug the monitor power cable from the electrical outlet.

CAUTION: Read and follow the Safety Instructions before cleaning the monitor.

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

• To clean your anti-static screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the anti-static coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.
• Use a lightly-dampened, soft 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 get scratched 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.
