When you leave the computer idle for a longer period, the imaging board now delivers horizontal sync only. As a result, the display's micro controller switches off a number of internal circuits. The power consumption has now dropped with about 42 %.

At last, the imaging board delivers no sync signals at all, and the micro-controller switches off all but one power supplies in the display. Only the micro-controller's own supply keeps on running, resulting in a very low power consumption of 6 W.

If you start using the computer again, the imaging board switches on both sync signals, and the micro-controller switches on the display.

The times after which the different steps of power management must become active, is set in the PC's display properties.
