CHAPTER 2. CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS
1. CONNECTING THE MONITOR AND TURNING THE MONITOR ON AND OFF
Caution: • When connecting, ensure that both the monitor and com-
puter are switched off.
• Be careful not to overly bend the cable or add extension
cords as this could lead to malfunction.
Cable storage
If necessary, excess cable can be housed in the stand.
1.
Remove the cover.
Gently pull the top of the cover towards yourself.
Gently pull the top of the cover towards yourself.
2.
Run cable along the back of the stand.
Pass cable in front of the stand, and then bring it through the back.
• If the display is to be rotated, first house the cables with the dis-
play in the long height position, so there is sufficient length when
the display is turned.
3.
Refit the cover.
Be careful not to pinch the cable.
• If the cover is hard to refit, do not force it. Check whether cables
are trapped.
Caution: If the display is to be rotated, first house the cable, and then
check while gently turning the display. If it cannot be turned,
rehouse the cable with sufficient slack. (If there is insufficient
cable length, rotation will be impossible. Forcing rotation may
cable length, rotation will be impossible. Forcing rotation may
cause cable disconnection.)
CONNECTING THE MONITOR TO A COMPUTER
Connecting using accessory analog signal cable
Connect the accessory analog signal cable to the analog RGB input ter-
minal of the display, and the analog RGB output terminal of the com-
puter.
• Paying attention to connector direction, firmly insert the signal
cable to terminal, and then tighten the screws at both sides.
If connecting to a D-sub 15 pin 2 row Apple Power Macintosh, attach a
Macintosh conversion adapter (commercially available) to the analog
signal cable.

When connecting using separately sold digital or analog
signal cables
signal cables
The separately sold display cable enables connection between the DVI-
I input terminal on the display and the digital or analog RGB output ter-
minal of the computer.
When connecting to a digital RGB output terminal:
• Use a digital signal cable (model name: NLC01E)
• For digital RGB connection, the monitor has an input for connecting
to a computer with a DVI-compatible output connector (DVI-D 24 pin
or DVI-I 29 pin) and SXGA output capability. (Depending on the type
or DVI-I 29 pin) and SXGA output capability. (Depending on the type
of computer to be connected, the display may not work correctly.)
When connecting to an analog RGB output terminal:
• Use an analog signal cable (model name: NLC02E).
• Paying attention to connector direction, firmly insert the signal
cable to terminal, and then tighten the screws at both sides.
Note: When using digital or analog signal cables, set [INPUT-2] to
[1 LINE].
Set the monitor as follows when establishing a digital connection with a
Power Mac using an ADC-DVI adapter made by Belkin. (Operation has
been checked with the Power Mac G4 M7627J/A)
• Perform settings with the Power Mac power supply off.
1.
After connecting the power cord, turn on the monitor’s main power.
2.
Press the
e
button and
d
button simultaneously, and while doing
this press the POWER button (i.e. turn the power on).
3.
Set the input terminal to which the Belkin ADC-DVI adapter is con-
nected to ON.
Use the SELECT button to select [INPUT1] or [INPUT2], and use
the
the
e d
buttons to select [ON] and [OFF].
• Do not set to [ON] if you are not using a Belkin ADC-DVI adapter,
as this may result in incorrect display.
4.
Press the power button, and turn off the monitor power.
This completes setting.

1. Connect a 2-input cable (purchased separately) to the DVI-I input
Cterminal on the display.
2. Connect the analog and digital signal cables (purchased separately)
to the 2-input cable, then connect to a computer.
• Paying attention to connector orientation, firmly insert the signal cable
into the PC, and then tighten the screws at both sides.
Notes:
• When using a 2-input cable, set [INPUT-2] to [2LINES].
• The monitor connected to the mini D-sub connector of the 2-input
cable may not be automatically recognized and setup under Plug &
