Abstract: A method includes detecting, through a processor of a source device and/or a processor of a target display communicatively coupled to a memory, a hot-plug event indicating coupling of the target display to the source device without shutting down both the source device and the target display when the target display is in a standby mode of operation thereof. The method also includes transitioning, through the processor of the source device and/or the processor of the target display, the target display from the standby mode of operation to an active mode of operation thereof based on a control signal from the processor of the source device and/or the processor of the target display following the detection of the hot-plug event. The active mode is associated with a higher power level than the standby mode.

Abstract: A method includes sensing distance between a user of a data processing device and a display unit of the data processing device or the data processing device through a distance sensor, and storing an element associated with a video frame or an image being rendered on the display unit separately from data related to the video frame or the image in a memory associated with a processor of the data processing device. The method also includes scaling, through the processor, the element in accordance with the sensed distance to an appropriate size thereof, and overlaying, through the processor, the scaled element on the data related to the video frame or the image during rendering thereof on the display unit.
