 Power management
The monitor is based on the VESA DPMS and the DVI DMPM stan-
dards.
To activate the monitor's Power Management function, both the video
card and the computer must conform to the VESA DPMS standard and
the DVI DMPM standard.
DPMS: Display Power Management Signalling

DMPM: Digital Monitor Power Management

 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 compliant and if it is set so that it can detect the Plug & Play mon-
itor.
There are many varieties of DDC due to the differences between sys-
tems. This monitor works with DDC2B.

 Height adjustment, angle adjustment, rotation (long height/width)
Caution:
•  Pressure from hands on the LCD panel could cause damage.
•  Be careful not to allow your fingers to be pinched.
1) Height adjustment
Adjust to an easy to view height.
2) Angle adjustment
Adjust to an easy to view angle.
3) Rotation (long height/width)
The display can be rotated for a long height or width to suit the dis-
played content.
•  Before rotating, move the display to its uppermost position. If the dis-
play is rotated while it is set low, it will contact the stand and could
lead to damage.
• The display can only be rotated through a range of 90°. Applying
excessive force may cause malfunction.
•  Do not apply excessive force when the cable is connected.
To set to long height
Gently turn in the clockwise direction (to 90°).
To set to long width
Gently turn in the counterclockwise direction (to 90°).
Note: The orientation of the display can be changed using Pivot Soft-
ware.
