Abstract: By partitioning the source PHY of a physical layer interface, such as a DisplayPort interface, between multiple power domains, dynamic switching between various power modes with faster entry and exit latency can be achieved in some embodiments. In some embodiments, the scheme may be hardware initiated and autonomous in nature. A controller can switch the PHY in and out of the various power consumption modes, dependent on usage scenarios.

Abstract: An apparatus for managing HDMI power is described herein. The method for managing HDMI power can include connecting a high definition multimedia interface (HDMI) of a computing device to a panel, where the computing device is inactive. The method can also include detecting, with the panel, a connection state and an energy request of the computing device through the HDMI. The method can provide power through the HDMI from a power supply of the panel to the computing device based on the connection state and the energy request of the computing device. The method can activate the computing device.
