Abstract: An example power controller includes a comparator to compare an amount of power supplied at a port of a display device to a first power threshold corresponding to a first operating mode of the display device and a second power threshold corresponding to a second operating mode of the display device. The first power threshold is different from the second power threshold. The power controller further includes a mode controller to configure the display device to operate in at least one of the first operating mode or the second operating mode based on an output of the comparator.

Abstract: Displays having calibrators are disclosed. An example display includes a sensor to measure a plurality of readings for color settings of a color pattern presented by the display. A processor is to calculate average values corresponding to respective ones of the plurality of readings for the color settings. A calibration manager is to generate calibrated measurement values based on the average values. The calibrated measurement values to enable determination of color space information for the display.

Abstract: In an example, a display device with power inputs includes a first power input to receive a first amount of input power, a second power input to receive a second amount of input power, a power allocator to combine at least a portion of the first amount of power with at least a portion of the second amount of power to form a combined output power, and a universal serial bus (USB) port to output at least a portion of the combined output power to a peripheral device.
