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.

Abstract: Described are examples for adjusting display level properties across multiple displays. One or more ranges of display brightness capability values that are supported by a given display device can be received for multiple display devices. For each of the multiple display devices, at least a portion of display brightness capability values in the one or more ranges of display brightness capability values can be mapped to selectable brightness levels available in an operating system. One of the selectable brightness levels can be determined as selected via the operating system. For each of the multiple display devices, a corresponding display brightness capability value mapped to the one of the selectable brightness levels can be determined and indicated to each of the multiple display devices, such that the multiple display devices may set different display brightness capability value brightness, but the brightness may be perceptually similar across the display devices.
