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.
•
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.
Image persistence
•
Image persistence is when a “ghost” of an image remains on the screen even after the monitor has been turned off.
Unlike CRT monitors, LCD monitors’ image persistence is not permanent. To alleviate image persistence, turn the
monitor off for as long as an image was displayed. If an image was on the monitor for one hour and a “ghost” of that
image remains, the monitor should be turned off for one hour to erase the image.
NOTE:
As with all personal display devices, NEC-Mitsubishi Electronic Displays recommends using a screen saver at
regular intervals whenever the screen is idle.
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 total. When the
display mode is changed, the OSD Image Adjust settings may need to be readjusted.
•
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 60 Hz refresh rate.
Message “OUT OF RANGE” is displayed (screen is either blank or shows rough images only)
•
Image is displayed only roughly (pixels are missing) and OSD warning “OUT OF RANGE” is displayed: Either signal
clock or resolution is too high. Choose one of the supported modes.
•
OSD warning “OUT OF RANGE” is displayed on a screen: Signal frequency is out of range. Choose one of the
supported modes.
LED on monitor is not lit (no green or amber colour can be seen)
•
Power Switch should be in the ON position and power cord should be connected.
Display image is not sized properly
•
Use the OSD Image Adjust controls to increase or decrease the Coarse total.
•
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.)
No Video
•
If no video is present on the screen, turn the Power button off and on again.
•
Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
