5.11 VESA Display Power

Management


Because of the tremendous amount of energy consumed by monitors when operating, the system
will reduce power consumption and extend monitor lifecycle by suspending the (switch off)
monitors and projectors when the system goes into sleep/standby.

This applies for all VESA Display Power Management compliant displays that are connected to
the VGA/DVI output of the system. The display device needs to comply with VESA display Power
Management system (DPMS).


Note that this requires a system supplied with a VGA/DVI output.


The VESA DPMS standard consists of four modes, Normal, Standby, Suspend and Off, and
applies to all Sync formats (e.g. VGA).

DPMS standard:

Normal

Standby

In Off mode some power may still be drawn in order to power indicator lights etc. EDID contains
the information on which mode a specific monitor supports.

TANDBERG supports all four modes. However, in F1 and above, all monitors not listed below are
automatically set to Off.
