Abstract: Techniques and mechanisms for power management of display devices based on an indication that a user exhibits interest in one, but not all, of said display devices. In an embodiment, logic of a computer device identifies a condition wherein a user of the computer device exhibits insufficient interest in a first display device, while exhibiting at least some interest user in a second display device. The first display device and the second display device support an extended display mode of an operating system. Based on the condition, the logic automatically reduces a consumption of power by the first display device. Of the first display device and the second display device, only the first display device is subjected to a power state transition based on the condition.
