Nuu B30 Pro PWM measurement
The Nuu B30 Pro's OLED panel offers options for 60Hz, 120Hz, or auto refresh rates but the measurements for dimming are identical across all options. The phone uses DC-like dimming above 40% brightness and switches to 1920Hz PWM below 40% brightness. It also uses a unique PWM algorithm with 60Hz brightness spikes. Unsure if this is helpful for PWM-sensitive folks.
