■DDC (Plug & Play)
This monitor supports the VESA DDC (Display Data Channel) stand-

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 varieties of DDC due to the differences between
systems. This monitor works with DDC1 and DDC2B.

4. INSTRUCTIONS FOR INSTALLING A VESA COMPLIANT ARM
An arm based on the VESA standard can be attached to the monitor.
The arm must be purchased separately.
When choosing the arm to be installed please take note of the follow-
ing points.
·The arm should be compatible with the VESA standard, and there
must be a gap of at least 75 mm x 75 mm between the screw
holes on the section to be attached.
·The arm must not fall off or break off after being attached to the
monitor.
Note: ·The same thing about the adapter cord and also RGB!!!!
·Please be careful not to hurt your fingers or injure yourself.
1. Turn off the power switch and remove the AC adapter from the
monitor’s power terminal.
2. Remove the stand cover.
Pull the lower section of the stand cover upward.
3. Being careful not to damage the monitor, spread out a soft cloth
and lay the monitor on it display-side down.
4. Remove the four screws and then remove the stand from the
monitor.
5. Attach the arm to the monitor with four screws.
6. Connect the AC adapter to the monitor’s power terminal.
Stand cover
Information
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
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 any other
kind of screw may lead to
the monitor falling off or
damage to the internal
part of the monitor.
