ity can cause moisture to build up within the monitor
due to condensation – this can cause an electrical short
circuit.
After transporting the monitor, wait until it has
reached ambient temperature before switching it on.

4.5. Power supply
DANGER!
Risk of electric shock!
Even when the device is switched off, some compo-
nents are live.
In order to disconnect the power to your monitor or
to completely isolate the device from voltage sourc-
es remove the mains plug from the socket.
• Operate the monitor only from a 100 to 240 V~ 50 to 60 Hz
earthed power socket that is close by and easy to access.
• To disconnect the power supply from your monitor, pull the
plug from the socket.
DANGER!
Risk of electric shock!
The monitor contains live parts. They pose a risk of elec-
tric shock or fire if an unintentional short circuit occurs.
Never open the monitor housing and do not push
objects inside the monitor through the slots and
openings.
• Do not place any objects on the cables as they may be dam-
aged.
• Keep the device at a distance of at least one metre from
sources of high-frequency or magnetic interference (televi-
sions, speakers, mobile telephones, etc.) to avoid malfunc-
tions and data loss.

7. Getting started
7.1. Before connecting the monitor
It is possible that your existing monitor supports a physical resolution that is not
supported by your new monitor. In this case, the image on your new monitor may
not appear correctly once it has been connected.
To prevent this, select a physical resolution that is supported by both monitors
and, if necessary, set this physical resolution in your operating system before
connecting the new monitor.
A table listing the physical resolutions supported by this monitor can be found in
section “7.6. Setting the monitor resolution”on page 19.
7.2. Mounting the stand
Attach the monitor stand as shown in the illustration. Carry out this step before con-
necting the monitor.
Place the monitor on a level surface with the monitor surface facing down.
Place the mounting plate of the monitor stand in the recess on the rear of the
monitor (A).
Use three of the supplied screws to screw the mounting plate together. Use a
Phillips screwdriver to do so.
Now attach the foot to the bottom of the stand (B). Take care to ensure that the
connecting piece fits in the device recesses.
Secure the foot with the remaining three screws supplied using the screwdriver.
Attach the mounted stand to the monitor (C) and attach it with three screws
supplied (D).
Place the cover on the stand (E).

7.3. Setup
Avoid glare, reflections and extreme dark-light contrasts to protect your
eyes.
The monitor should never be placed close to windows, because this is where the
workspace is illuminated the brightest by daylight. This brightness makes it more
difficult for the eyes to adjust to the darker screen.
Always position the monitor with the line of sight parallel to the window front.
The parallel line of sight must also be maintained with regards to artificial lighting
equipment. In other words, the same criteria and reasoning apply when the work-
space is illuminated with artificial light.
If it is not possible to position the monitor as described, the following measures
may be helpful:
• swivel, lower or tilt the monitor
• slats or vertical net curtains on the windows
• partition walls or changes to the lighting equipment.
Take regular breaks when working at your monitor, to avoid tension and
fatigue.
Sitting for prolonged periods without changing position can be uncom-
fortable. Correct posture is very important for minimising the risks of
physical injuries or damage.

• General – change position frequently (around every 20 to 30 minutes) and take
regular breaks to avoid fatigue.
• Back – when sitting at your workstation, your back must be supported by your
chair’s backrest, which must be upright or angled slightly back.
• Arms – your arms and elbows should be comfortable and relaxed. Your elbows
should be close to your body. Hold your forearms and hands roughly parallel to
the floor.
• Wrists – when working with the keyboard, mouse or trackball, wrists should be
elongated and bent at an angle of no more than 10°. Take care to ensure that
your wrists do not rest directly on the edge of the table.
• Legs – your thighs should be horizontal or angled slightly downwards. The lower
legs should form an angle of approx. 90° to the thighs. Your feet should rest flat
on the floor. Use a footrest if you need one, but first ensure that your seat height
has been adjusted correctly.
• Head – your head should be upright or bent slightly forward. Do not work with
your head or upper body twisted.
During work, the top edge of the monitor should be at or slightly below eye lev-
el.
The size of the distance between the monitor and the viewer depends on indi-
vidual requirements. Distances between 50 and 60 cm are commonly used.

7.4. Connection
DVI-D
DP HDMI
To avoid damage and malfunctions, only connect the connecting cable
when the monitor and computer are switched off.
7.4.1. Connecting the signal cable
Plug the signal cable into one of the connections on the monitor:
– HDMI
– DVI
– DP
Plug the other end into the appropriate connections on the computer.
Only one type of connection can be used at a time.
7.4.2. Connecting the power supply
Connect the supplied mains adapter to the connection of the device.
Plug the other end into an easily accessible mains socket. The mains socket must
be close to the monitor and easily accessible (use the same electric circuit as for
the computer).
7.5. Switching on/standby
Press the button to switch on the device.
Press the button again to switch the device into standby mode.

7.6. Setting the monitor resolution
The monitor supports the physical resolutions listed in the table. The aspect ratio
of the monitor is 16:9. You will get an image that is free from distortion by selecting
the 2560 x 1440 pixels resolution. This is a native 16:9 aspect ratio. Image distortions
or black bars at the end of the picture can occur with all other resolutions.
Set the physical resolution on your computer according to the instructions in
your operating system.

9. Energy-saving features
This monitor switches to different energy-saving modes, which are specified by
the respective computer/operating system. This complies with the current require-
ments for reducing the energy consumption.
The monitor supports the following types of energy-saving modes:
Status
Power consump-
tion
(nominal value)
Colour of the
operating light
Ready for oper-
ation (approx.)
ON < 60 W (max.) Blue –
STANDBY < 0.5 W flashes Blue 2 seconds
EXT. STANDBY1< 0.5 W – 5 seconds
Depending on the operating system, the monitor remains in energy-saving mode
until you press a button on the keyboard or move the mouse. The monitor requires
about 2 seconds to switch from standby mode to operating mode "On".2
10. Troubleshooting
If problems occur with your monitor, make sure that the monitor has been properly
installed. If the problems persist, then read this section for information about possi-
ble solutions.
10.1. No picture/picture interference
• The mains cable must be firmly seated in the socket and the power switch (if
available) must be switched on.
• The computer must be switched on and the connecting cable must be firmly
seated in the socket.
• The set values of the operating system must be suitable for the monitor. To avoid
distortion, select a resolution of 16:9.
• If the screen saver is activated or the monitor is in standby mode, press any but-
ton on the keyboard or move the mouse.
• Move the devices responsible for the distortion (mobile phones, speakers etc.)
away from your monitor.
2The device is switched to the extended standby mode by pressing the button
