A plurality of input images in an input video signal of a wide dynamic range is received. A specific setting of global light modulation is determined based on a specific input image in the plurality of input images. The specific setting of global light modulation produces a specific dynamic range window. A plurality of input code values in the specific input image is converted to a plurality of output code values in a specific output image corresponding to the specific input image. The plurality of output code values produces the same or substantially the same luminance levels as represented by the plurality of input code values. Any other pixels in the specific input image are converted to different luminance levels in the specific output image through display management.
