Abstract: Methods, systems and apparatuses may provide for technology that generates a backlight compensation signal based on a user input, an operating system input and an adjustment output, wherein the backlight compensation signal includes a plurality of transitions in a time domain, and wherein the plurality of transitions occur at a frequency that exceeds a frequency threshold. The technology may also automatically apply the backlight compensation signal to a low pass filter to obtain a smoothened compensation signal and adjust a brightness level of the display panel based on the smoothened compensation signal and a modified pixel buffer.

Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed to reduce dynamic refresh rate power consumption. An example apparatus includes interface circuitry, machine-readable instructions, and at least one processor circuit to be programmed by the machine-readable instructions to modify a value of a source clock based on a detected application type, generate a pixel clock value change request based on the application type, cause transmission of the pixel clock value change request to a display, and cause transmission of pixels to the display at the modified source clock value.
