Claim:
1. A method for generating drive values for a display comprising a light source modulation layer and a display modulation layer, the method comprising: receiving a first frame of image data; determining a first set of light source modulation layer drive values based at least in part on the first frame of image data; determining an expected luminance profile at the display modulation layer, based at least in part on the first set of light source modulation layer drive values; determining display modulation layer drive values, based at least in part on the expected luminance profile; comparing the display modulation layer drive values to a predetermined threshold maximum value and a predetermined threshold minimum value; flagging image regions for which any of the display modulation layer drive values are above the predetermined threshold maximum value or below the predetermined threshold minimum value, wherein flagging the image regions comprises: based on the flagged image regions, adjusting a second set of light source modulation layer drive values for portions of a second frame of image data, wherein adjusting the second set of light source modulation layer drive values comprises:
