Monitor Specifications

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

Power Management Modes

If you have VESA's DPM 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 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) for S2240L

18 W (Typical) for S2240L 24 W (Maximum) for S2340L

19 W (Typical) for S2340L Active-off mode Inactive Inactive Blank 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 except power button is pressed in Active-off mode, the following messages will be displayed:

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

NOTE: Dell S2240L/S2340L monitor is ENERGY STAR®-compliance.

* 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.

Plug and Play Capability

You can install the monitor in any Plug and Play compatible system.

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. When the pixel remains permanently lit, it is known as a "bright dot". Wh en 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 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

CAUTION: Read and follow the safety instructions before cleaning the monitor. CAUTION: 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, slightly 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 slightly 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 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 power off your monitor when not in use.

Troubleshooting

Dell™ S2240L/S2340L monitor

Self-Test Built-in Diagnostics In-Store Demo Common Problems Product Specific Problems

WARNING: Before you begin any of the procedures in this section, follow the Safety Instructions.

Self-Test

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

1. Turn off both your computer and the monitor.

2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (black connector) and the Analog (blue

connector) cables from the back of computer.

3. Turn on the monitor.

The floating dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains white. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.

4. This box also appears during normal system operation, if the video cable becomes disconnected or damaged. The monitor will enter Power Save Mode

in 5 minutes if left at this state.

5. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.

If your monitor screen remains blank after you use the previous procedure, check your video controller and computer, because your monitor is functioning properly.

Built-in Diagnostics

Your monitor has a built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent problem with your monitor, or with your computer and video card.
