This monitor supports the VESA DDC (Display Data Channel) standard. DDC is a signal standard for carrying 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 varieties of DDC due to the differences between systems. This monitor works with DDC1 and DDC2B.

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.

Arms or stands able to be used

Attachments must satisfy the following.

• Compatible with the VESA standard

• Ha ve a gap of 75 mm x 75 mm between the screw holes on the section to be attached

• Not be likely to fall off or break off after being attached to the monitor.

Notes: • 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 a malfunction.

6. Attach the arm to the monitor with the four screws.

Press power button

How to attach the arm or stand

• Be careful not to overly bend the cable or add extension cords as this could lead to malfunction.

• While following these instructions, please also refer to the installation instructions in the operation manual included with the arm or stand.

1. Turn off the monitor’s power and unplug AC plug from AC outlet.

2. Remove the cable.

3. Spread out a soft cloth on a suitable horizontal surface.

4. Being careful not to damage the monitor, gently lay the monitor on it display-side down.

5 Remove the four screws and then remove the stand from the moni-

tor.

Note: The screws used to attach the arm should be M4 screws with a

length of 6 mm ~ 8 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 injury.
