Power Management
If your computer has
previously been used
with a CRT monitor and is
currently configured to a
display mode outside the
range that the Flat Panel
monitor can display, you
may need to re-attach the
CRT monitor temporarily
until you have re-configured
the computer, preferably to
1024 x 768 at 60Hz.
To benefit from power management, the monitor must be used in conjunction
with a computer that implements the Video Electronics Standards Association
(VESA) Display Power Management Signalling (DPMS) Standard.
The power management feature is invoked when the computer recognizes
that you have not used your mouse or keyboard for a user-definable period.
There are several states as described in the table below.

day, or whenever you expect to leave it unused for long periods during the
day.
