1. A method comprising: determining a latency associated with changing a backlight brightness from a first level to a second level; based on the determined latency, coordinating adjustments to a) the backlight brightness and b) image luminance to occur in such a manner so as to substantially avoid associated visually disturbing artifacts; and coordinating the adjustments to a) the backlight brightness and b) image luminance with at least one of a vertical refresh and a scanline interval rate, the coordinating the adjustments to a) the backlight brightness and b) image luminance with at least one of a vertical refresh and a scanline interval rate includes dividing the latency by a vertical refresh and scanline period.
