An external display may support bias lighting via lights located on the rear of the display. Embodiments provide a baffle connected to the rear of the display such that the baffle redirects light output from the rear-facing bias lights. Rather than redirect bias light output off a surface behind the display, embodiments provide a known surface for redirecting bias light output towards the front side of a display. A multi-segment baffle may be adjusted by articulating segments of the baffle and modifying the angles of redirection of the bias light output. Such adjustments modify the size of an opening between the baffle and the display and thus alter the characteristics of the bias light output. An inner surface of the baffle may be coated with a reflective material to improve efficiency. The baffle may be formed from a portion of a rear cover of the display.
