ised service partners.
4.4. Environmental conditions
• Only use the device in accordance with the environmental
conditions specified in the technical data.
DANGER!
Risk of electric shock!
Major changes in temperature or fluctuations in humid-
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.

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 “7.7. Setting the display 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 device onto the stand. Ensure that the connecting piece fits into the
slots on the device.
Screw the foot to the arm using the screw provided.
Insert the retaining plate into the recess of the device. Make sure that the con-
nector fits into the recess.
Screw the arm to the device using the four screws provided.

16
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:
• turn, lower or angle the display screen
• 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. Mounting on the wall
You can mount the device on the wall with the aid of a wall mount.
To enable wall mounting, first remove the device stand.
To do this, remove the four screws on the mounting plate of the foot.
Remove the stand.
Install the wall mount on the intended holes on the device housing. The hole
spacing is 100 x 100 mm according to the VESA standard.
When mounting the device, make sure that the screws are no larger
than M4x16

7.5. Connection
~HDMI HDMI DP
To avoid damage and malfunctions, only connect the connecting cable
when the monitor and computer are switched off.
7.5.1. Connecting the signal cable
Plug the signal cable into one of the connections on the monitor:
– HDMI (2X)
– DP
Plug the other end into the appropriate connections on the computer.
Only one type of connection can be used at a time.
7.5.2. Connecting the headphones
Plug the cable with a 3.5mm jack plug into the stereo jack connection .
WARNING!
Risk of hearing damage!
Using headphones/earphones to listen to a device at
high volumes for an extended period can damage your
hearing.
Before pressing play, set the volume to the lowest
setting.
Start playback and increase the volume to a comfort-
able level.

7.5.3. Connecting the power supply
Connect the supplied mains adapter to the~connection on 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).
7.6. Switching on/standby
Press the button to switch on the device.
Press the button again to switch the device into standby mode.
This monitor features sensor buttons, that do not contain a mechanical
switch. The button function is triggered by briefly pressing the tactile
dots beneath the button symbol.
7.7. Setting the display resolution
The monitor supports the physical resolutions listed in the table. The aspect ratio of
the display screen is 16:9. You will get an image that is free from distortion by select-
ing the 2,560 x 1,440 pixels resolution. This is a native 16:9 aspect ratio. Image dis-
tortions 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.

10. 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 < 40 W (max.) Blue –
STANDBY < 0.5 W Orange 2 seconds
EXT. STANDBY < 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".
