1. A display system comprising:
an optical engine comprising a plurality of laser light sources;
a beam combiner configured to:
combine a first subset of a plurality of laser light beams output by the plurality of laser light sources into a first combined laser light beam; and
combine a second subset of the plurality of laser light beams into a second combined laser light beam that is different from the first combined laser light beam; and
an optical scanner configured to form a first set of pixels using the first combined laser light beam and to form a second set of pixels using the second combined laser light beam, wherein the first set of pixels at least partially overlaps the second set of pixels within a field of view of the display system.
