2. INSTALLATION
2.1 Precautions
•
Keep your original packaging. It is designed for this display and is
the ideal protection during transport.
•
•
•
Avoid reflections in the flat panel to reduce eye strain.
Place the display on a strong and stable table or desk.
Keep the display away from heat sources and provide enough
ventilation in case it is built in a rack or console.
•
•
Make sure the computer is switched off before connecting the
signals.
Do not block or cover the openings in the external power supply
block. Also, do not turn the power supply upside down or at its
side. Doing so would cause overheating of the power supply.
2.2. Before installing the display
Important:
In the factory, the height-positioning system in the display foot is
blocked with a strap to prevent damage during transportation.
Before installing the display, you must remove this strap.
To remove the strap:
1 Position the display with its rear side facing you.
2 If the foot cover is mounted on the foot, lift up the 2 clips of the foot
cover to release the cover from the foot.
3 Pull the lower side of the cover towards you and simultaneously
slide the cover downward.
4 Pull the red strap out of the fixation holes in the foot.
You can better leave the cover off the foot while connecting the signal
cables to the display.

2.3 Portrait or landscape position
You can change the orientation of the panel at any time, but it is more
convenient to select landscape or portrait orientation before
connecting the cables.
To change the panel orientation:
1 Stand at the front side of the panel and take the panel at both
sides.
2 Very important: Tilt the panel before changing
the orientation.
Should you change the panel orientation without
tilting it first, you might irreversibly damage the
tilt & swivel mechanism.
3 To change from portrait to landscape, turn the
panel counterclockwise while lifting it up
slightly.
To change from landscape to portrait, turn
clockwise.
2.4 Connecting the signals
To get access to the connectors, open the cover of the connector
compartment by pulling down the 2 clips of the cover.
To connect the video & sync signals:
1 Connect one end of the video cable to the DVI input (5) of the
display.
2 Connect the other end of the video cable to the video output of
your video source (Computer graphics board with digital video
output).

3 Route the cable so that it enters the connector compartment at the
place where the cover is bulged.
To connect the power:
1 Connect the output of the 12V DC power supply to the DC input (6)
of the display.
2 Connect one end of the proper power cable to the AC input of the
12V DC power supply.
3 Connect the other end of the power cord to a grounded power
outlet.
2.5. Routing the signal cables
After connecting all cables, fix them in the cable tie at the rear of the
connector compartment. You can also bind the cables together by
means of the 2 velcro strips included in the package.
After fixing the cables, put the connector compartment cover back in
place. Pay attention that the signal cables are positioned under the
bulge in the cover.
Next, fix the cables in the plastic clamps on the foot. At last, put the
foot cover back in place.
To put the foot cover in place:
1 Push the upper side of the cover onto the foot, so that the hooks
on the cover are positioned right under the holes in the foot.
2 Slide the cover upward while moving the lower side of the cover

angle and vertical viewing angle.
2.7 Starting up
Proceed as follows:
1 Switch on the computer.
2 If necessary, select a suitable resolution in the computer operating
system. You will have to select a resolution that corresponds to the
panel orientation (landscape or portrait).
Please refer to the possible resolutions in the Technical

5. MAINTENANCE
Panel
Take care not to damage or scratch the panel. Clean with a soft
woolen or cotton towel. Use a watery solution or a mild commercial
glass-cleaning product.
Cabinet
Do not use chemical cleaning products, benzene, toluene, xylene or
other solvents. Clean with a soft cloth dampened with mild detergent
and water. Repeat with water only and wipe dry with a dry cloth.
Removing dust from the rear of the glass panel
It may be possible that dust particles have entered the display and are
stuck to the rear of the glass.
We recommend to let this cleaning procedure be done in a BARCO
service center.
However, when really necessary, you can perform the cleaning on site
if you can work in conditions that are as clean and dust-free as
possible. This is to avoid more dust entering the display when opening
it.
To remove the glass panel:
1 Switch off the display.
2 Tilt the panel.
3 Unscrew the 4 sunken screws at the rear, fixing
the glass panel and bezel.
4 Remove the bezel with glass panel.
Cleaning instructions:
-
Dust, fingerprints, grease etc. can be removed by using a soft
damp cloth (a small amount of mild detergent can be used on the
cloth, NOT solvent).
-
-
Do not apply liquid directly to the LCD surface as excess liquid
may cause damage to internal electronics.
Take care not to touch the I-guard light sensor on the LCD panel.

6. TROUBLESHOOTING
Windows does not show the desired display
settings
Should you have problems selecting display settings for portrait
oriented displays in the Windows Display Properties control panel,
disable the option Hide modes that this monitor cannot display in
the control panel (see below).
Information:
The display contains a special memory chip that contains information
about the display's scanning capabilities. When Windows starts up, it
reads the contents from this memory and presents a number of
display settings in the Display Properties control panel, based on this
information.
The memory of this display contains the information the display can
handle scanning systems up to 120 Hz. That is why Windows will
propose a display setting with a high refresh rate. However, it is best
to select a refresh rate of 60 Hz.
The information that the display can be used in portrait mode, is also
stored in the display memory. However, Windows does not recognize
this and presents only default landscape modes if the option Hide
modes that this monitor cannot display in the control panel is
enabled.
Pixel Faults
Permanently dark or bright pixels can happen to TFT displays. 20 or
less permanently dead pixels do not make out a good case for
exchanging the unit.
Please contact our Customer Service Department if the number of
pixel faults exceeds the above-mentioned figure.
