This new display, debuting first on the Galaxy Note20 Ultra 5G, can hit 120Hz when high rates are wanted for gaming, drop to 60Hz for video playback, 30Hz while you’re messaging, or as little as 10Hz when it’s exhibiting a still image.
In the lowest setting, Samsung claims it will probably use just 60 % of the normally-required power, while other displays can’t regulate without starting to flicker. Samsung Display mobile display planning VP Ho-Jung Lee said in a commentary “Our Adaptive Frequency display technology is expected to considerably enhance the user experience by calibrating refresh rates consistent with the requirements of specific software and therein more precisely allocating available power.”
Overall, the corporate claims its tech can save power by up to 22 percent in comparison to other screens. On the other hand, as Anandtech points out, it’s no longer clear how granular the control can be, or if it’s restricted to the desired settings. We’ve seen adaptive sync technology in monitors and even TVs used to reduce tearing, however, on those small screens, a minimum of the first implementation is most commonly about saving power.
