PROBLEM TO BE SOLVED: To provide a light source device, a monitor device, and a method for driving the light source device in which it is possible to reliably control the output (amount of light emitted), while reducing the effect of individual differences in laser light sources, when using the plurality of laser light sources, and to provide a projector with higher-resolution by reliably controlling the output of the light source in accordance with image signals or the like. SOLUTION: The light source device 2 includes: the plurality of laser light sources 10 that emit laser light; and a light source driving section 12 that drives the laser light sources 10 by a first current value or a second current value. The light source driving section 12 controls the light quantity of the laser light emitted from the plurality of laser light sources 10 by switching the respective numbers of the laser light sources 10 that are driven by the first current value or the second current value in the plurality of laser light sources 10. The first current value is a value less than the threshold of the laser light of the laser light sources 10 and the second current value is a value greater than the threshold of the laser light of the laser light sources 10.
