Remove Monitor Stand for Mounting
To prepare the monitor for alternate mounting purposes:
1. Place hands on each side of the monitor and lift up to the highest position. Remove the cable cover (Figure S.1).
2. Disconnect all cables.
3. Place monitor face down on a non-abrasive surface (Figure S.2).
NOTE:Handle with care when monitor facing down, for avoiding damage to the front control buttons.
4. Remove the 4 screws connecting the stand to the monitor (Figure S.2).
NOTE:In order to avoid stand drop, when removing screws, please support stand with your hand.
Screen Rotation
Before rotating, the screen must be raised to the highest level to avoid knocking the screen on the desk or pinching with your
fingers.
To raise the screen, with one hand, grip the top of the display by the handle using the other hand to grip the bottom. Lift up to
the highest position (Figure RL.1).
To rotate screen, place hands on each side of the monitor screen and turn clockwise from Landscape to Portrait or counter-
clockwise from Portrait to Landscape (Figure R.1).

8. Reverse this process to re-attach stand.
NOTE:Use only VESA-compatible alternative mounting method.
Handle with care when removing stand.
NOTE:Match “TOP SIDE” mark on stand to top side of the monitor head when
re-attaching stand.
Flexible Arm Installation
This LCD monitor is designed for use with a flexible arm. To mount the monitor to a flexible arm:
1. Follow the instructions on how Remove Monitor Stand for Mounting to remove the stand.
2. Using the 4 screws from the stand removal, attach the arm to the monitor (Figure F.1).
NOTE:1. When mounting, use ONLY the screws (4 pcs) that were removed from the stand to avoid damage to the monitor
or stand.
2. The LCD monitor should only be used with an approved arm (e.g. GS mark). To meet the safety requirements,
the monitor must be mounted to an arm, which guaranties the necessary stability under consideration of the
weight of the monitor.
3. The mounting stand must be able to sustain at least 23.2 kg and be UL certified.

Troubleshooting
No picture
•The signal cable should be completely connected to the display card/computer.
•The monitor does not support DisplayPort converter signal.
•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.
•If the front LED is dark green or dark blue, check the status of the IPM mode (see page 13).
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, 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.
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 blank screen: Signal frequency is out of range. Choose one of the
supported modes.
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 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.
LED on monitor is not lit (no blue or amber colour can be seen)
•Power Switch should be in the ON position and power cord should be connected.
Picture is not as bright
•Make sure ECO MODE and AUTO BRIGHTNESS are turned off.
•If the brightness fluctuates make sure AUTO BRIGHTNESS is turned off.
Display image is not sized properly
•Use the OSD Image Adjust controls to increase or decrease the H. SIZE.
•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
•Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
•Some video cards do not output video signal when monitor is turned OFF/ON or disconnect/connect from the AC
power cord under low resolution with DisplayPort.
No Sound
•Make sure the speaker cable is proper connected.
•Check to see if mute is activated.
•Check the volume in the OSD menu.
•Check selected OSD’s Tools to “SOUND INPUT”, when DisplayPort is in use.
Brightness difference during multiple monitor usage
•Change Auto Brightness to OFF and adjust brightness.
NOTE:When Auto Brightness is set to ON, the monitor automatically adjusts brightness to the environment.
When condition is difference, monitor brightness will be difference.

Using the Auto Brightness function
The brightness of the LCD screen can be set to increase or decrease depending on the amount of ambient light within the
room. If the room is bright, the monitor becomes correspondingly bright. If the room is dim, then the monitor will dim
accordingly. The purpose of this function is to make the viewing experience more comfortable to the eye in a variety of lighting
conditions.
The Auto Brightness function is set to 3 by default.
SETUP
Use the following procedure to select the Brightness Range that the monitor will use when the Auto Brightness function is
activated.
1. Set the BRIGHT level. This is the brightness level that the monitor will go up to when the ambient light level is highest.
Make sure the room is at its brightest when setting this level.
Select “1” or “3” in the AUTO BRIGHTNESS menu (Figure 1). Then use the front buttons to move the cursor up to the
BRIGHTNESS setting. Choose the desired brightness level (Figure 2).
2. Set the DARK level. This is the level of brightness that the monitor will go down to when the ambient light level is low.
Make sure the room is at its darkest when setting this level.
Then use the front buttons to move the cursor up to the BRIGHTNESS setting. Choose the desired brightness level
(Figure 3).
Figure 1Figure 2

When the “Auto Brightness” function is enabled the Brightness level of the screen changes automatically according to the
lighting conditions of the room (Figure 4).
