Conserving Energy Using Monitor Dimming

Typically, developers (e.g. users) use multiple monitors to increase screen real estate. However, the user tends to only focus on one monitor at a time. While multiple monitors increase the productivity of the user at times, the additional displays require power to operate which leads to energy cost. The energy cost may seem small for an individual user. However, the aggregate cost across an enterprise may be significant

when compounded over many users with multiple display configurations. Enterprise

administrators manage datacenter sprawl, office space consolidation and other large scale efforts to reduce an energy footprint. Thus, it is advantageous for the enterprise to have ways to reduce energy cost.

Disclosed is a method and system for conserving energy via monitor dimming. The method and system dynamically controls intensity of displays in an environment where a user has more than one display. The method and system determines current focus of a user using one or more of eye tracking location, current mouse location and media playback. A display rendering engine may be used to track the mouse movement. For example, the display rendering engine calculates the cursor position based on aggregate screen geometry to determine coordinates and neighboring coordinates in the display screen. The user is allowed to set timeout threshold preferences for each display screen. The timeout threshold preferences may be options such as x minutes of inactivity, current focus (e.g., immediate inactivity), never for a display, time of day and day of week.

Figures 1, 2 and 3 illustrate a visual example of the method and system of conserving energy using monitor dimming. Figure 1 illustrates a typical monitor environment where all the users' monitors are considered actively engaged, when the user interacts with any of the display monitors.

As illustrated in Figure 2, if the user focuses on the first monitor, then the presently disclosed system dims the other two display monitors.

If the user attempts to move the mouse to the left to interact with the first and second monitors, then the presently disclosed system insta...
