A method (500) of configuring a light source array (110) of a system is disclosed. The system further comprising a display (110) and a camera (108), wherein the light source array (110) comprises a plurality of individually controllable lighting units, and wherein the light source array (110) has been positioned relative to the display (110). The method (500) comprises: rendering (502) a pattern (122) on the display (110), controlling (504) one or more lighting units of a first segment (112) of the light source array (110) according to a first light setting, controlling (506) one or more lighting units of a second segment (114) of the light source array (110) according to a second light setting, obtaining (508) an image (140) captured by the camera (108), the image (140) comprising the display (110), the first segment (112) and the second segment (114), detecting (510) the pattern (122) in the image (140), detecting (512) the first light setting and the second light setting in the image (140), determining (514) positions of the first segment (112) and the second segment (114) relative to the display (110) in the image (140) based on the first light setting, the second light setting and the pattern (122) in the image (140), and determining (516) a mapping of the plurality of the individually controllable lighting units with respect to the display (110) based on the positions of the first segment (112) and the second segment (114) relative to the display (110) in the image (140), such that when media content is being rendered on the display (110) one or more lighting units of the plurality of the individually controllable lighting units are controlled based on the media content according to the mapping.
