DMPM is monitor power management applied over the digital DVI interface. TANDBERG
supports DMPM in software F2 and above. Six monitor power states are defined.
Monitor On Power state
Transmitter (TANDBERG codec) and receiver (Monitor) are powered and active. This power state
is equivalent with the DPMS normal mode.
Intermediate Power state
When the codec goes from active to standby, it turns off the DVI transmitter and the monitor can
go from Monitor On
Power state to Intermediate Power state
Active-off Power state
The monitor can go from Intermediate Power state to Active-off Power state when the monitor
timer expires.
Non-Link Recoverable Off Power State
The monitor can enter Non-Link Recoverable Off Power State when the codec is switched off or if
the DVI cable is disconnected. This power state is equivalent to the DPMS “Off (with no DPMS
recovery)” state.
Monitor Power Switch Off Power state
This state can be entered when the power switch on the monitor is toggled to its off position. This
state has two sub-states dependent on if the codec is switched on or off.
