Abstract
In general, in one aspect, an apparatus receives pixels associated with an image destined for an external display and determines a reduced backlight brightness for the external display and corresponding changes to the pixels to approximate overall quality of the image with current backlight brightness. Backlight commands are generated for the reduced backlight brightness and the pixels are enhanced to correspond to the reduced backlight brightness. The enhanced pixels and the backlight commands are transmitted to the external display via a display interface that supports backlight control. The display interface may be a wireless interface or a wired (cabled) interface (e.g., display port (DP), high definition multimedia interface (HDMI), video graphics array (VGA)). The functionality of the apparatus is included in a computing device so that backlight brightness reductions and corresponding pixel changes can be made taking into account policies of the computing device and user preferences.
