BARCO METHEUS DPMS OVERVIEW
Introduction
The Barco Metheus DPMS (Display Power Management Signaling)
Screen Saver allows the user to set power and monitor saving
features for medical monitors driven by BarcoMed Imaging Boards. At
the end of the work day, the monitor will enter certain DPMS states as
requested by the imaging board. This is accomplished through
standardized signals between the monitor and imaging board.
The default DPMS state is the Off state. In addition to simply entering
the Off state after the work day, the user can specify that the monitor
first go through two other DPMS states before going into Off state.
These two other states are Stand-By and Suspend. The user can
specify how much time should be spent in each state in the “Amount
of Time in each DPMS Power State” section.
A valuable feature of the Barco Metheus DPMS Screen Saver is that it
will automatically ensure that CRT based monitors are warmed up for
the start of the work day. All CRT based monitors require some warm-
up time before they are at full performance.
On Barco ImageTile displays, the I-GUARD will stabilize the image
within a few seconds after the monitor returns to the active state, thus
eliminating the need for a warm-up period at the beginning of the work
day.
On CRT based monitors, such as the Barco MGD series, a “regular”
screen saver can be invoked during user inactivity during the work
day. This “regular” screen saver and its settings can be chosen from
the “Screen Saver During Work Day” section. We recommend using
an all black screen saver, such as the “Barco Metheus Blank Screen”
saver, for the longest phosphor life.
On LCD based monitors, such as the Barco ImageTile displays, it is
not necessary to invoke a screen saver as there is no CRT phosphor
to preserve. However, one can extend the life of the backlight in the
LCD monitor, in addition to realizing great power savings, during
period of user inactivity by using DPMS to quickly enter the Off state.
We recommend setting the work day to be as short as possible to get
the maximum power savings on ImageTile displays.
The Barco Metheus DPMS Screen Saver can also be used when no
one is logged on.
