Using Power Management

The LCD monitor follows the VESA approved DPM Power

Management function.

The power management function is an energy saving function that automatically reduces the power consumption of the display when the keyboard or the mouse has not been used for a fixed period.

The power management feature on your new display has been set to the “ON” mode. This allows your display to enter a Power Saving Mode when no signal is applied. This could potentially increase the life and decrease the power consumption of the display.

STANDBY mode is used when the display is connected to an RS-232C cable or when using the INPUT DETECT function.

ECO STANDBY uses less power, put the RS-232C and

INPUT DETECT functions are not available.

NOTE 2: IMAGE PERSISTENCE

Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided.

To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

As with all personal display devices, NEC DISPLAY SOLUTIONS recommends displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

Please set “SCREEN SAVER”, “DATE &TIME” and “SCHEDULE SETTINGS” functions to further reduce the risk of Image persistence.

For long life use of Public Display

< Image Sticking of LCD Panel >

When LCD panel is operated continuously for long hours, a trace of electric charge remains near the electrode inside LCD, and residual or

“ghost” image of previous image may be observed. (Image Persistence)

Image Persistence is not permanent, but when fixed image is displayed for long period, ionic impurities inside LCD are accumulated along the displayed image, and it is observed permanently. (Image Sticking)

< Recommendations >

For preventing the fast transition to Image Sticking, and for longer life usage of LCD, following are recommended.

1. Fixed image should not be displayed for long period, and changed to another images with short cycle.

2. When no use, please turn off the monitor by remote control, or use Power Management Function of monitor or use Schedule Function of monitor.

3. Reducing the environmental temperature is effective for long life use.

When Protection board (glass, acryl) is installed over the LCD surface, enclosed into the box / wall, or stack the monitor, please utilize the temperature sensors inside monitor.

To reduce the environmental temperature, the monitor should be set Low Brightness or Cooling Fan “ON” by using Screen sever Function.

4. Please use “Screen Saver Mode” of monitor.

Remote Control ID Function

REMOTE CONTROL ID

The remote control included with the display can be used to control up to 26 individual

MultiSync monitors using what is called the REMOTE CONTROL ID mode. The REMOTE

CONTROL ID mode works in conjunction with the Monitor ID, allowing control of up to 26 individual MultiSync monitors. For example: if there are many monitors being used in the same area, a remote control in normal mode would send signals to every monitor at the same time Figure 1. Using the remote in REMOTE CONTROL ID mode will only operate one specific monitor within the group Figure 2.

Monitor ID:1

MONITOR ID and IR CONTROL

Using one PC or one infrared wireless controller, up to 26 individual LCD4020/LCD4620 monitors can be controlled through a daisy chain via RS-232C connection.

1. Connect PC and LCD4020/LCD4620.

Connect a PC’s RS-232C control output to the LCD4020/LCD4620’s RS-232C input. You can then connect the RS-232C output from the

LCD4020/LCD4620 to another LCD4020/LCD4620’s RS-232C input. Up to 26 monitors can be connected using RS-232C.

2. Set Monitor ID and IR Control mode.

For proper operation, the Monitor ID should be set in the OSD menu of each monitor that is in the chain. The Monitor ID can be set under the “MULTI DISPLAY” menu in the OSD. The Monitor ID number can be set within a range from 1 to 26. No two monitors should share the same Monitor ID number. It is recommended to number each monitor in a daisy chain sequentially from 1. The first monitor in the daisy chain is designated as the primary monitor. Subsequent monitors with the chain are secondary monitors.

In the “ADVANCED OPTION” menu on the first monitor in the RS-232C daisy chain set the “IR CONTROL” to “PRIMARY”.

Set the “IR CONTROL” to “SECONDARY” on all other monitors.

3. Press the “DISPLAY” button on the remote control while aiming at the “PRIMARY” monitor. The Information OSD will be shown at top left side of the screen.

Monitor ID: Displays the ID number of the current monitor within the daisy chain.

Target ID: Displays the ID number of the monitor that to be controlled via daisy chain from the current monitor.

Press the “+” or “-” buttons to change the “Target ID” to show the ID number of the monitor to be controlled. To control the entire daisy chained monitors simultaneously, select “ALL” as the “Target ID.”

Note: If the monitor is in ECO Standby mode, RS-232C functionality is stopped.

4. Use the wireless remote controller to control the “SECONDARY” monitor while aiming at the “PRIMARY” monitor.

The “MENU OSD” will appear on the selected target monitor.

NOTE: If the “ID No.” mode select OSD is showing, press the “DISPLAY” button on the remote control while pointing at the “PRIMARY” monitor to clear this OSD.

Features

Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and weight limitations.

Colour Control Systems: Allows you to adjust the colours on your screen and customize the colour accuracy of your monitor to a variety of standards.

OmniColor: Combines Six-axis colour control and the sRGB standard. Six-axis colour control permits colour adjustments via six axes (R, G, B, C, M and Y) rather than through the three axes (R, G and B) previously available. The sRGB standard provides the monitor with a uniform colour profile. This assures that the colours displayed on the monitor are exactly the same as on the colour printout (with sRGB supporting operating system and sRGB printer). This allows you to adjust the colours on your screen and customise the colour accuracy of your monitor to a variety of standards.

sRGB Colour Control: A new optimized colour management standard which allows for colour matching on computer displays and other peripherals. The sRGB standard, which is based on a calibrated colour space, allows for optimal colour representation and backward compatibility with other common colour standards.

OSD (On-Screen-Display) Controls: Allow you to quickly and easily adjust all elements of your screen image via simple to use on-screen menus.

Plug and Play: The Microsoft ® solution with the Windows ® operating system facilitates setup and installation by allowing the monitor to send its capabilities (such as screen size and resolutions supported) directly to your computer, automatically optimizing display performance.

IPM (Intelligent Power Manager) System: Provides innovative power-saving methods that allow the monitor to shift to a lower power consumption level when on but not in use, saving two-thirds of your monitor energy costs, reducing emissions and lowering the air conditioning costs of the workplace.

FullScan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.

VESA Standard (FDMIv1) Mounting Interface: Allows users to connect their LCD monitor to any VESA standard (FDMIv1) third party mounting arm or bracket. Allows for the monitor to be mounted on a wall or an arm using any third party compliant device. NEC recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in North America.

DVI-D: The digital-only subset of DVI ratified by the Digital Display Working Group (DDWG) for digital connections between computers and displays. As a digital-only connector, analog support is not provided off a DVI-D connector. As a DVI-based digital only connection, only a simple adapter is necessary for compatibility between DVI-D and other DVI-based digital connectors such as DFP and P&D. The DVI interface of this display supports HDCP.

TILE MATRIX, TILE COMP: Demonstrates multiple screens with an accurate image and compensates for the bezel width.

ZOOM: Expands the image individually for horizontal and vertical direction.

RS-232C daisy chain: You can control the multiple monitors by controller or wireless remote controller.

Self-diagnosis: When an internal error should occur, a failure state will be indicated.

CableComp: Automatic long cable compensation prevents image quality degradation (colour shift and dull signals) caused by long cable lengths.


English-34
