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

2.6 Tilt and swivel positioning  
Adjust the position of the panel for best viewing conditions.  
The display foot allows adjusting the panel height, horizontal viewing  
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  
specifications.  
Note: The recommended resolution for best image quality is 2048  
x 1536 or 1536 x 2048.

4. ADVANCED FUNCTIONS  
4.1. About this chapter  
Important  
The functions described in this chapter are intended for trained  
service staff only!  
Improper use of these functions may irreversibly damage the display.  
BARCO cannot be held responsible for the results or damage caused  
by improper use of these functions.  
This chapter describes only the Advanced functions in the OSD  
menus. For a description of the other functions (standard functions),  
please refer to the previous chapter, Operation .  
In this chapter, we assume the advanced user knows how to use the  
OSD system: How to browse through the menus, how to enter menus  
and sub-menus, how to select and change values.  
These actions are described in the previous chapter.  
About the Advanced functions  
The advanced functions are extensions of the OSD menus. A stan-  
dard user browsing through the OSD system sees only the standard  
functions. When logged in in advanced mode, the user sees the  
standard and advanced functions in the OSD menus.

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.
