1. An Information Handling System (IHS), comprising:
- an embedded controller (EC); and
a memory coupled to the EC, the memory having program instructions stored thereon that, upon execution, cause the EC to;
determine a characteristic of a display having a backlight; and
control a buck-boost converter to increase or decrease a voltage applied to the backlight based upon a frame rate of a video signal received by the display.

Abstract
Systems and methods for reducing the power consumption of high-dynamic range (HDR) displays via buck-boost conversion are described. In some embodiments, an information handling system (IHS) may include an embedded controller (EC) and a memory coupled to the EC, the memory having program instructions stored thereon that, upon execution, cause the EC to: determine a characteristic of a display having a backlight, and control a buck-boost converter to increase or decrease a voltage applied to the backlight based upon a frame rate of a video signal received by the display.
