causing a content-presentation device to enter a calibration mode in which the content- presentation device outputs for presentation reference visual content displayed at a reference position of a display screen of the content-presentation device;

causing a lighting device to emit light in accordance with a lighting parameter, wherein the lighting parameter specifies a position, within the lighting device, of emitted light, and wherein initially the position of the light emitted in accordance with the lighting parameter does not positionally correspond to the reference position of the display screen of the content-presentation device;

receiving first input indicating an adjustment to the lighting parameter;

responsive to receiving the first input, causing the lighting device to adjust the lighting parameter, thereby causing the lighting device to adjust the emitted light;

receiving second input indicating that the position of the adjusted emitted light positionally corresponds to the reference position of the display screen of the content-presentation device, wherein the second input indicating that the adjusted emitted light positionally corresponds to the reference position of the display screen of the content-presentation device comprises the second input indicating that the position of the emitted light and the reference position of the display screen of the content-presentation device have a threshold extent of positional correspondence with each other; and

responsive to receiving the second input, calibrating the lighting device at least by (i) causing storage of the adjusted lighting parameter and (ii) causing the lighting device to be configured to emit light in accordance with the stored lighting parameter.
