The invention describes a method of adjusting the light output of a projector system comprising a light source (1) and a display unit (2) with controllable elements (M1, M6) for controlling the path of the light originating from the light source (1), which method comprises compiling a switching sequence (S1, SRGB, Sint) for the controllable elements (M1, M6) of the display unit (2), which switching sequence (S1, SRGB, Sint) comprises long segments and short segments, whereby a long segment is of a duration greater than or equal to a predefined threshold and a short segment is of a duration less than or equal to the predefined threshold; obtaining a light output adjustment measure (15, 15') by which the light output of the light source (1) is to be adjusted; and generating a light pulse sequence (L50, L25, LR50, LG5o, LB5o, LRmt5o, LGmt5o, LBmt5o) such that the duration of a light pulse (LP) of the light pulse sequence (L50, L25, LR50, LG5O, LB5O, LRint50, LGint5o, LBint5o) during a segment of the switching sequence (S1, SRGB, Sint) corresponds to the light output adjustment measure (15, 15'), and arranging the light pulse (LP) relative to the switching sequence (S1, SRGB, Sint) such that the activation of the light pulse (LP) does not occur during a short segment of the switching sequence (S1, SRGB, Sint). The invention further describes a system (3) for adjusting the light output of a projector system (9), a light source driving arrangement (7) for a light source (1) in a projector system, a display unit controller (10') for controlling a display unit (2) of a projector system, and a projector system (9).
