A:Answer Hi Sidney! In addition to manually fine tune your image's brightness (Settings > Picture > Expert Settings > Brightness), the QN90A TV features Intelligent Mode which enables the TV to recognize and analyze the surroundings, noise, content, and your usage patterns to provide the best viewing experience. You can enable Intelligent Mode by going to Home > Settings > General > Intelligent Mode Settings. Adaptive Picture, which is among the options, optimizes brightness and provides the best picture quality in real time, based on the lighting condition and your content. ^Gina
