Abstract:
A method comprising:transitioning a display device from a first power state to a second power state in response to signal activity to the display device falling below a predetermined activity threshold, the second power state to consume less power than the first power state; when in the second power state, transitioning the display device to a third power state in response to the signal activity to the display device remaining below the predetermined threshold for a predetermined period of time, the third power state is to consume less power than the second power state; when in the second or third power state, transitioning the display device to the first power state in response to signal activity to the display device rising above the predetermined threshold; and when in the first, second, or third power state, transitioning the display device to a fourth power state in response to a a power control signal from a computer system separate from the monitor, the power control signal does not transition a power state of the computer system, the fourth power state is to consume less power than the third reduced power state.
