DDC (Plug & Play)
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
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 DDC2B.

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 computer are
switched off.
• Be careful not to over bend the cable or add extension cords as this
could lead to a 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.
2.
Run cable along the back of the stand.
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.
1-1. Connecting the monitor to a computer
The accessory signal cable enables connection of two computers.
(One analog and one digital connection.)
(One analog and one digital connection.)
• The separately sold 2-input cable enables connection of two comput-
ers to the DVI-I input terminal.
• When using the 2-input cable, set the connecting input terminal
[INPUT-2] to [2LINES] under the MODE SELECT-2 Menu.
