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 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:
VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption
Normal operation Active Active Active White 23 W (maximum)
Normal operation Active Active Active White 17 W (typical)
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.
Activate the computer and the monitor to gain access to the OSD.
* Zero power consumption in OFF mode can only be achieved by disconnecting the main cable from the monitor.
** Maximum power consumption with max luminance and Contrast, 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 its Extended Display Identification Data (EDID) to the
computer 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. The visible result is a fixed pixel
that appears as an extremely tiny dark or bright discolored dot. When the pixel remains permanently lit, it is known as a “bright dot.” When the pixel remains black, it
is known as a “dark dot.” In almost every case, these fixed pixels are hard to see and do not detract from display quality or usability. A display with 1 to 5 bright/dark
dot is considered normal and within competitive standards. For more information, visit 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 the monitor 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.

Attaching the Stand
Removing the Monitor Stand for VESA Wall Mount
Connecting Your Monitor
Attaching Dell Soundbar AX510PA (optional)
Attaching the Stand
NOTE: The stand base is detached when the monitor is shipped from the factory.
1. Assemble the stand riser to stand base.
a. Place the monitor stand base on a stable table top.
b. Slide the monitor stand body in the correct direction down onto the stand base until it clicks into place.

2Attach the stand assembly to the monitor.
a. Place the monitor on a soft cloth or cushion near the edge of a desk.
b. Align the stand assembly bracket to the monitor groove.
c. Slide the bracket towards the monitor until it locks in place.

Removing the Monitor Stand for VESA Wall Mount
To remove the stand assembly from the monitor:
1. Place the monitor panel on soft cloth or cushion on a stable flat table.
2. Use a long screwdriver to push the release latch located in a hole just above the stand.
3. Once the latch is released, remove the stand assembly from the monitor.

Connecting Your Monitor
WARNING: Before you begin any of the procedures in this section, follow the Safety Instructions.
To connect your monitor to the computer:
1. Turn off your computer and disconnect the power cable.
Connect the blue (VGA) cable from your monitor to your computer.
NOTE: If your computer supports a DVI connector, connect the white DVI cable (optional) from your monitor to your computer.
NOTE: Do not connect both the VGA and the DVI cables to the computer as all monitors ship with the VGA cable attached to the
monitor.
2. Connect either the white (digital DVI-D) or the blue (analog VGA) display cable to the corresponding video port of your computer. Do not use both cables on the same
computer. Use both the cables only when they are connected to two different computers with appropriate video systems.
