Monitor Specifications

The following sections give you information about the various power management modes and pin assignments for various connectors for your monitor.

Power Management Modes

If you have VESA's DPMS compliance display card or software installed in your PC, the monitor automatically reduces 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:

Activate the computer and wake up 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.

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 required, the

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

LCD Monitor Quality & 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 spot.

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 fixed pixels is considered

normalandwithincompetitivestandards.Formoreinformation,seeDellSupportsiteat:support.dell.com.

Maintenance Guidelines

Caring for Your Monitor

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

lTo 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.

lUse 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.

lIf 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.

lHandleyourmonitorwithcareasdarker-colored plastics may scratch and show white scuff marks more than lighter-coloredmonitor.

CAUTION: Safety Instructions

Read and follow these instructions when connecting and using your computer monitor:

lTohelpavoiddamagingyourcomputer,besurethatthevoltageselectionswitchonthepowersupplyforthecomputerissettomatchthealternating

current (AC) power available at your location:

¡115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as Japan, South Korea (also 220 volts (V)/60

hertz (Hz)), and Taiwan.

¡230 volts (V)/50 hertz (Hz) in most of Europe, the Middle East, and the Far East.

lAlways be sure that your monitor is electrically rated to operate with the AC power available in your location.

lDo not store or use the monitor in locations that are exposed to heat, direct sunlight, or extreme cold.

lAvoid moving the monitor between locations with large temperature differences.

lDo not subject the monitor to severe vibration or high impact conditions. For example, do not place the monitor inside a car trunk.

lDo not store or use the monitor in locations exposed to high humidity or dusty environment.

lDo not allow water or other liquids to spill on or into the monitor.

lKeep flat panel monitor in room temperature conditions. Excessive cold or hot conditions can have an adverse effect on the liquid crystal of the display.

lNever insert anything metallic into the monitor openings. Doing so may create the danger of electric shock.

lTo avoid electric shock, never touch the inside of the monitor. Only a qualified technician should open the monitor case.

lNever use your monitor if the power cable has been damaged. Ensure that nothing rests on your computer's cables and that the cables are not located

where they can be stepped on or tripped over.

lBe sure to grasp the plug, not the cable, when disconnecting the monitor from an electric socket.

lOpenings in the monitor cabinet are provided for ventilation. To prevent overheating, these openings should not be blocked or covered. Avoid using the

monitor on a bed, sofa, rug, or other soft surface, as doing so may block the ventilation openings in the bottom of the cabinet. If you place the monitor

in a bookcase or an enclosed space, be sure to provide adequate ventilation and air flow.

lPlace your monitor in a location with low humidity and minimum dust. Avoid places similar to a damp basement or dusty hallway.

lDo not expose the monitor to rain or use it near water (in kitchens, next to swimming pools, etc.). If the monitor accidentally gets wet, unplug it and

contact an authorized dealer immediately. You can clean the monitor with a damp cloth when necessary, being sure to unplug the monitor first.

lPlace the monitor on a solid surface and treat it carefully. The screen is made of glass and can be damaged if dropped or hit sharply.

lLocate your monitor near an easily accessible electric outlet.

lIf your monitor does not operate normally - in particular, if there are any unusual sounds or smells coming from it - unplug it immediately and contact an

authorized dealer or service center.

lDo not attempt to remove the back cover, as you will be exposed to an electrical shock hazard. The back cover should only be removed by qualified

service personnel.

lHigh temperatures can cause problems. Don't use your monitor in direct sunlight, and keep it away from heaters, stoves, fireplaces, and other sources

of heat.

lUnplug the monitor when it is going to be left unused for an extended period of time.

lUnplug your monitor from the electric outlet before any service is performed.

FCC Notice (U.S. Only)

CAUTION: Use of controls, adjustments, or procedures other than those specified in this documentation may result in exposure to shock,

electrical hazards, and/or mechanical hazards.

NOTE: This monitor does not need or have a voltage selection switch for setting the AC voltage input. It will automatically accept any AC input voltage

according to the ranges defined in the "Electrical Specifications" section in the User's Guide.

FCC Class B

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the manufacturer's instruction

manual, may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital
