NOTE 1: IMAGE PERSISTENCE  
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence occurs  
when 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, MITSUBISHI ELECTRIC 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” 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)  
English-27  
< 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.  
NOTE 2: HOW TO SETUP SCHEDULE  
Using the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor will be  
activated.  
You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input source the  
monitor will use for each scheduled activation period. A check mark in the box next to the number of the schedule indicates that  
the selected schedule is in effect.  
To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule.  
Use the (+) and (-) buttons to move the cursor horizontally within the particular schedule. Use the ( ) and ( ) buttons to increase  
time and select input port. The “SET” button is used to make a selection.  
If you create a schedule but do not want to use a power on time, select “--” in the “ON” time slot.  
If you do not want to use a power off time select “--” in the OFF time slot.  
If there is no input selected (“--” showing in the input spot) the input from the previous schedule will be used.  
The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly.  
When schedules are overlapping, scheduled Power ON time has priority over scheduled Power OFF time.  
If there are two schedules programmed for the same time, then the highest numbered schedule has priority.  
When the “OFF TIMER” (see page 25) is set, the “SCHEDULE” function is disabled.

Features  
Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and  
weight limitations. The monitor’s small footprint and low weight allow it to be moved or transported easily from one location  
to another.  
Color Control Systems: Allows you to adjust the colors on your screen and customize the color accuracy of your monitor  
to a variety of standards.  
sRGB Color Control: A new optimized color management standard which allows for color matching on computer displays  
and other peripherals. The sRGB standard, which is based on a calibrated color space, allows for optimal color representa-  
tion and backward compatibility with other common color 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 95/98/Me/2000/XP 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.  
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.  
Multiple Frequency Technology: Automatically adjusts monitor to the display card’s scanning frequency, thus displaying  
the resolution required.  
FullScan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.  
VESA Standard Mounting Interface: Allows users to connect their LCD monitor to any VESA standard 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.  
MITSUBISHI ELECTRIC 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 be-  
tween 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.  
TILING, Frame compensation: Demonstrates multiple screens with an accurate image and compensates for the bezel  
width.  
ZOOM: Expands the image individually for horizontal and vertical direction.  
Self-diagnosis: When an internal error should occur, a failure state will be indicated.

Troubleshooting  
No picture  
The signal cable should be completely connected to the display card/computer.  
The display card should be completely seated in its slot.  
Front Power Switch and computer power switch should be in the ON position.  
Check to make sure that a supported mode has been selected on the display card or system being used.  
(Please consult display card or system manual to change graphics mode.)  
Check the monitor and your display card with respect to compatibility and recommended settings.  
Check the signal cable connector for bent or pushed-in pins.  
Power Button does not respond  
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.  
Image persistence  
Please be aware that LCD Technology may experience a phenomenon 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.  
NOTE: As with all personal display devices, MITSUBISHI ELECTRIC 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.  
Image is unstable, unfocused or swimming is apparent  
Signal cable should be completely attached to the computer.  
Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine adjustment.  
When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.  
Check the monitor and your display card with respect to compatibility and recommended signal timings.  
If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.  
Image of component signal is greenish  
Check to see if the DVD/HD input connector is selected.  
LED on monitor is not lit (no green or red color can be seen)  
Power Switch should be in the ON position and power cord should be connected.  
Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).  
RED LED on monitor is blinking  
A certain failure might have occurred, please contact your nearest authorized MITSUBISHI ELECTRIC service facility.  
Display image is not sized properly  
Use the OSD Image Adjust controls to increase or decrease the coarse adjustment.  
Check to make sure that a supported mode has been selected on the display card or system being used.  
(Please consult display card or system manual to change graphics mode.)  
Selected resolution is not displayed properly  
Use OSD Display Mode to enter Information menu and confirm that the appropriate resolution has been selected.  
If not, select corresponding option.  
No Sound  
Check to see if speaker cable is properly connected.  
Check to see if mute is activated.  
Check to see if volume is set at minimum.  
Remote Control is not available  
Check the Remote Control’s batteries status.  
Check if batteries are inserted correctly.  
Check if the Remote Control is pointing at the monitor’s remote sensor.  
“SCHEDULE”/“OFF TIMER” function is not working properly  
The “SCHEDULE” function will be disabled when the “OFF TIMER” is set.  
If the “OFF TIMER” function is enable and the power to the LCD monitor is turned off if the power supply is interrupted unexpect-  
edly, then the “OFF TIMER” will be reset.  
Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or degrada-  
tion.
