What is Automatic Phosphor Aging Compensation (APAC™)?

APAC functions only when black bars are present, either during letterboxed material or when viewing a 4:3 image on a 16:9 television. When these bars are present, APAC imperceptibly moves the image up and down, or to the right and left, one pixel at a time. APAC acts as a screen saver for the television. Plasma monitors are more prone to image burn in, meaning that after continuously watching material where black bars are present, these lines could be permanently burnt into the phosphors. APAC can significantly reduce the change of burn-in.
