The HomeView can dim its display to just 0.3 nits for use on a nightstand or in dark environments, making it Apple's lowest-ever display brightness. The 7-inch Liquid Retina display automatically adjusts its brightness as lighting conditions change, reaching up to 500 nits in bright rooms. Its 0.3-nit minimum allows it to dim substantially at night. True Tone also helps the screen adapt to changing ambient light. Previously, Apple's dimmest display technology went down to just 1 nit.
