The present disclosure is directed to systems and methods of optimizing display image quality on display devices having a plurality of display power modes. Each power mode has associated therewith a respective baseline allowable percentage of distorted pixels and a baseline first relationship between an original pixel value and boosted pixel value. Display control circuitry determines a baseline second relationship using the baseline percentage of distorted pixels and the baseline first relationship. The display control circuitry selects a plurality of test distorted original pixel values and determines a respective test first relationship. Using the test distorted original pixel value, the respective test first relationship, and the baseline second relationship, the display control circuitry determines a respective PSNR and value indicative of the change in display image quality for each of the test distorted original pixel values.
