Abstract
Devices and methods for controlling display brightness may include receiving a brightness input for controlling a luminance level of at least one display in communication with the computer device. The devices and methods may include receiving high dynamic range (HDR) content and standard dynamic range (SDR) content for presentation on at least one display. The devices and methods may include generating adjusted SDR content by using the brightness input to modify luminance of the SDR content. The devices and methods may include blending the adjusted SDR content and the HDR content together to create a composed framebuffer content with the adjusted SDR content and the HDR content and transmitting the composed framebuffer content for presentation on at least one display.
