5.11VESA 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 need 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).

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.
