Zusammenfassung:	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. According to one embodiment, a display for presenting information generated by an Information Handling System (IHS) includes a screen disposed on a front side of the display, one or more bias lights disposed on a rear side of the display, a baffle comprising a baffle surface, the baffle coupled to the rear side of the display, and a selectively reflective layer disposed on the baffle surface, wherein the selectively reflective layer has a reflectivity that is changeable to selectively reflect a varying amount of light outputted from the bias lights.
