Dell Display Manager User's Guide Overview Dell Display Manager is a Windows application used to manage a monitor or a group of monitors. It allows manual adjustment of the displayed image, assignment of automatic settings, energy management, image rotation and other features on select Dell models. Once installed, Dell Display Manager will run each time the system starts and will place its icon in the notification tray. Information about monitors connected to the system is always available when hovering over the notification tray icon. Using the Quick Settings Dialog Clicking Dell Display Manager’s notification tray icon opens the Quick Settings dialog box. When more than one supported Dell model is connected to the system, a specific target monitor can be selected using the menu provided. The Quick Settings dialog box allows convenient adjustment of the monitor’s Brightness and Contrast levels, Preset Modes can be manually selected or set to Auto Mode, and the screen resolution can be changed.

The Quick Settings dialog box also provides access to Dell Display Manager’s advanced user interface which is used to adjust Basic functions, configure Auto Mode and access other features. Setting Basic Display Functions A Preset Mode for the selected monitor can be manually applied using the menu on the Basic tab. Alternatively, Auto Mode can be enabled. Auto Mode causes your preferred Preset Mode to be applied automatically when specific applications are active. An onscreen message momentarily displays the current Preset Mode whenever it changes. The selected monitor’s Brightness and Contrast can also be directly adjusted from the Basic tab. Assigning Preset Modes to Applications The Auto Mode tab allows you to associate a specific Preset Mode with a specific application, and apply it automatically. When Auto Mode is enabled, Dell Display Manager will automatically switch to the corresponding Preset Mode whenever the associated application is activated. The Preset Mode assigned to a particular application may be the same on each connected monitor, or it can vary from one monitor to the next.

Dell Display Manager is pre-configured for many popular applications. To add a new application to the assignment list, simply drag the application from the desktop, Windows Start Menu or elsewhere, and drop it onto the current list. NOTE: Preset Mode assignments targeting batch files, scripts, and loaders, as well as non-executable files such as zip archives or packed files, are not supported and will be ineffective.

Applying Energy Conservation Features On supported Dell models the PowerNap tab will be available to provide energy conservation options. When the screensaver activates, the monitor’s Brightness can automatically be set to minimum level or the monitor can be put to sleep in order to save additional power.

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: E1715S: VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption Normal operation Active Active Active White 15 W (Maximum) ** 11 W (Typical) Active-off mode Inactive Inactive Blank Glowing white 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: Dell E1715S There is no signal coming from your computer. Press any key on the keyboard or move the mouse to wake it up. If there is no display, press the monitor button now to select the correct input source on the On-Screen-Display menu. Activate the computer and monitor to gain access to the OSD. NOTE: The Dell E1715S monitor is ENERGY STAR®-compliant.

* 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.

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.” 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 fixed pixels is considered normal and within competitive standards. For more information, see Dell Support site at: http://www.dell.com/support/monitors. 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.

1. The socket-outlet should be installed near the equipment and should be easily accessible. 2. The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin.

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

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. 2. Connect either the black (digital DP) or the blue (analog VGA) display connector cable to the corresponding video port on the back of your computer. Do not use both cables at the same time. Use both the cables only when they are connected to two different computers with appropriate video systems. Connecting the blue VGA Cable Connecting the black DP cable Note: The graphics are used for the purpose of illustration only. Appearance on the computer may vary.

Removing the Monitor Stand After placing the monitor panel on a soft cloth or cushion, complete the following steps to remove the stand: 1. Use a long screwdriver to press and hold the release latch located in a hole just above the stand. 2. While the release latch is pressed down, remove the stand from the monitor slowly.
