The monitor is based on VESA DPMS (Display Power Management Signaling).
To activate the monitor's Power Management function, both the video
card and the comp uter must conform to the VESA DPMS standard.

■ DDC (PLUG & PLAY)
■ ■
This monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for carry ing out Plug & Play functions on the
monitor or PC. It transfers information such as degree of resolution
between the monitor and PC. You can use this function if your PC is DDC
compliant and if it is set so that it can detect the Plug & Play monitor.
There are many va rieties of DDC due to the d ifferences between sys tems. This monitor works with DDC1 and DDC2B.

1-5. INSTRUCTIONS FOR ATTACHING A VESA COMPLIANT ARM
An arm or stand based on the VESA standard (comme rcially available)
can be attached to the monitor.
Procurement of the arm or stand is at the customer's discretion.
When choosing the arm to be installed please take note of the following
points.
• The arm should be compatible with the VESA standard, and there
must be a gap of 75mm x 75mm between the screw holes on the
section to be attached.
• The arm m ust not fall off or break off after being attached to the
monitor.
Note: Do not overly bend the cable or add extension cords as this
could lead to malfunction.
1. Turn off the power switch and remove the AC adapter from the
monitor's power terminal.
2. Being careful not to damage the monitor, spread out a soft cloth and
lay the monitor on it display-side down.
4. Attach the arm to the monitor with four screws.
Note: The screws used to attach the arm should be M4 screws with a
length of 4 mm ~ 6 mm protruding from the surface to be
attached. Using different screws could lead to malfunction or
may lead to the monitor falling off, internal damaged, personal
injuly.

3. Remove the four screws and then remove the stand from the monitor.
Note:
• The stand is specially made for use with this monitor. Once having
removed the stand, never attempt to attach it to another device.
• Once having removed the screws, store them together with the
stand and if the stand is ever re-attached be sure to use the original
screws.
Using different screws could lead to malfunction.
5. Connect the AC adapter to the monitor's power terminal.
