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 or stand based on the VESA standard (purchased separately)
can be attached to the monitor. To install the arm an AC adapter

When choosing the arm to be installed take note of the following
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.
If an arm is attached, a USB hub cannot be used. (This is because
the arm is installed inside the monitor stand.)

1. Turn off the main power switch and remove the power plug.
2. Remove the rear cover.
Place your hand on the upper opening of the rear cover 1 and pull it
upward 2.
3. Remove the stand cover.

Information: The screws used to attach the arm should be M4
screws with a length of 4 ~ 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.
12. Connect the AC adapter (purchased separately).
Connect the AC adapter’s DC plug to the AC adapter’s connec-
tion terminal , and place the cord inside the cord hook .
