Abstract
Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.
