Abstract: Circuits, methods, and apparatus that may provide power supply voltages in a safe and reliable manner that meets safety and regulatory concerns and does not exceed physical limitations of cables and other circuits and components used to provide the power supply voltages. One example may provide a cable having a sufficient number of conductors to provide power without exceeding a maximum current density for the conductors. Another example may provide a cable having more than the sufficient number of conductors in order to provide an amount of redundancy. Current sense circuits may be included for one or more conductors. When an excess current is sensed, a power source in the power supply may be shut down, the power source may be disconnected from one or more conductors, or both events may occur.

Abstract: Techniques are disclosed to select display settings for a display device. Device capabilities may be read from a display device and a determination made whether the device capabilities support other display formats than are read from the display, for example, a high dynamic range (HDR) format or a high resolution format. When the device capabilities do not include an format supported by a video source, video may be driven from the video source to the display device in the format and, if confirmation is received that the display device displays the driven video, settings may be stored for the display device identifying the format as a one supported by the display device. Additionally, interconnect may be tested by estimating noise levels generated by the interconnect to a network connection and/or by estimating network throughput both when video is driven over the interconnect and when it is not. Display formats may be selected for the device based on a maximum data rate of a network connection that can be maintained while the interconnect carries video.
