TrantaLocked Posted October 13, 2022 Share Posted October 13, 2022 There are a few characteristics of a PWM signal from high to low like voltage, frequency and duty ratio. However, which of these characteristics are controlled by the motherboard? Is there a handshake that let's the display choose what it wants, or does the motherboard firmware force one set of values regardless of which display is installed? So for example, does the motherboard only control voltage level and the display handles the rest, or does the motherboard also control the frequency of the signal?
