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 input from keyboard, mouse or other input devices is detected by the computer, the monitor will automatically "wake up". The following table shows the power consumption and signaling of this automatic power saving feature:

VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption
Normal operation( with Dell Soundbar and USB active) Active Active Active Green 65 W (maximum)
Normal operation Active Active Active Green 32 W (typical)
Active-off mode Inactive Inactive Blanked Amber Less than 3 W
Switch off
Off Less than 1 W

NOTE: The OSD will only function in the 'normal operation' mode. Otherwise one of the following messages will appear when the “menu” or “plus” buttons are pressed when in Active-off mode.

1. Analog Input

In Power Save Mode

Press Any Key on Keyboard or Move Mouse


2. Digital Input

In Power Save Mode

Press Any Key on Keyboard or Move Mouse

Activate the computer and 'wake up' the monitor to gain access to the OSD.

This monitor is ENERGY STAR®-compliant as well as TCO '99 / TCO '03 power management compatible.

* Zero power consumption in OFF mode can only be achieved by disconnecting the main cable from the monitor.

ENERGY STAR® is a U.S. registered mark. As an ENERGY STAR® Partner, DELL has determined that this product meets the ENERGY STAR® guidelines for energy efficiency.

Universal Serial Bus (USB) Interface

This monitor supports High-Speed Certified USB 2.0 interface.*

  Data Rate Power Consumption
High speed 480 Mbps 2.5W (Max., each port)
Full speed 12 Mbps 2.5W (Max., each port)
Low speed 1.5 Mbps 2.5W (Max., each port)

USB ports:

  • 1 upstream - rear
  • 4 downstream - 2 on rear; 2 on left side

NOTE:  USB 2.0 capability requires 2.0 capable computer 

NOTE:  Monitor's USB interface works ONLY when monitor is Powered ON (or in Power Save Mode). Switching your monitor OFF and then ON would re-enumerate its USB interface; attached peripherals may take a few seconds to resume normal functionality.

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. If desired, the user can select different settings, but in most cases monitor installation is automatic.

Caring for Your Monitor

CAUTION: Read and follow the safety instructions before cleaning the monitor. 
CAUTION: Before cleaning the monitor, unplug the monitor from the electrical outlet. 
  • 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 plastics. Avoid using detergent of any kind as some detergents leave a milky film on the plastics. 
  • If you notice a white powder when you unpack your monitor, wipe it off with a cloth. This white powder occurs during the shipping of the monitor.
  • Handle your  monitor with care as darker-colored plastics may scratch and show white scuff marks more than lighter-colored monitor.
