Blue Light: Filters out blue light to protect your eyes by adjusting how much blue light is shown -- 80%, 70%, 60%, or 50 Note: Higher values allow more blue light through. For the best protection select a lower value. 8. Dark boost: This boosts the amplitude of the dark color levels of the display- blacks will be less black. The higher the level, the higher the boost. 9. Adaptive Contrast: This method usually increases the global contrast of many images, especially when the usable data of the image is represented by close contrast values. This allows for areas of lower local contrast to gain a higher contrast. The method is useful in images with backgrounds and foregrounds that are both bright or both dark. In particular, the method can lead to better views of bone structure in x-ray images, and to better detail in photographs that are over or under-exposed.
