3. How to assemble your monitor hardware
If the computer is turned on you must turn it off before continuing. 
Do not plug-in or turn-on the power to the monitor until instructed to do so. 
1. Attach the monitor base.
Please be careful to prevent damage to the monitor. 
Placing the screen surface on an object like a stapler or a 
mouse will crack the glass or damage the LCD substrate 
voiding your warranty. Sliding or scraping the monitor 
around on your desk will scratch or damage the monitor 
surround and controls. 
Protect the monitor and screen by clearing a flat open area 
on your desk and placing a soft item like the monitor 
packaging bag on the desk for padding.
Gently lay the screen face down on a flat clean padded 
surface.
While holding the monitor firmly against the desk, pull 
the monitor stand arm upwards clear of the monitor. 
Orient and align the stand base socket with the end of the 
stand arm, then push them together until they click and 
lock into place. 
Gently attempt to pull them back apart to check that they 
have properly engaged.
Carefully lift the monitor, turn it over and place it upright 
on its stand on a flat even surface.
You should position the monitor and angle the screen to 
minimize unwanted reflections from other light sources.

2. Connect the PC video cable 
Do not use both DVI-D cable and D-Sub cable on the 
same PC. The only case in which both cables can be 
used is if they are connected to two different PCs with 
appropriate video systems. (Not available for analog-only 
models).
To Connect the D-Sub Cable
Connect the plug of the D-Sub cable (at the end without 
the ferrite filter) to the monitor video socket. Connect the 
other end of the cable (at the end with the ferrite filter) to 
the computer video socket.
Tighten all finger screws to prevent the plugs from 
accidently falling out during use.
To Connect the DVI-D Cable
Connect the plug of the DVI-D cable (at the end without 
the ferrite filter) to the monitor video socket. Connect the 
other end of the cable (at the end with the ferrite filter) to 
the computer video socket.
Tighten all finger screws to prevent the plugs from 
accidently falling out during use.
The DVI-D format is used for direct digital connection 
between source video and digital LCD monitors or 
projectors. The digital video signals produce a superior 
quality picture than analog video signals.
The video cable included in your package and the socket 
illustrations on the right may vary depending on the LCD 
model.
3. Connect the audio cable.
Connect the audio cable between the socket on the rear of 
the monitor (Line In) and your computer audio outlet. 
You may connect headphones to the headphone jack 
found next to the Line In jack of the monitor.
