Abstract
Example display power management control circuitry is to determine a baseline image quality parameter associated with a baseline display power mode based on: a baseline first relationship parameter associated with a first relationship between original and boosted pixel values; a baseline percentage of pixels having a color value; and a baseline second relationship parameter associated with a second relationship between the numbers of original pixel values and boosted pixel values; determine a value of a subsequent first relationship parameter based on an adjusted second relationship parameter and a second percentage of pixels having the color value; determine a second image quality parameter associated with the subsequent first relationship parameter, the adjusted second relationship parameter, and the second percentage of pixels; and select the subsequent first relationship parameter and the adjusted second relationship parameter based on comparing the second image quality parameter to the baseline image quality parameter.
