Automatic adjustment of display refresh frequency on television devices running Google’s operating system allows the screen to synchronize with the frame rate of the content being played. For example, a movie filmed at 24 frames per second (fps) will be displayed at 24Hz, while a television broadcast at 60fps will be displayed at 60Hz. This adjustment aims to avoid judder and improve the viewing experience.
The principal advantage of this functionality is the elimination of motion artifacts that can arise when content is displayed at a different rate than its original capture rate. Historically, viewers had to manually adjust settings, or rely on imperfect processing within the television, to mitigate these issues. Modern implementation offers a streamlined, automated solution, contributing to smoother, more accurate video playback.
