This Windows setting fixes the worst tradeoff of owning a 120Hz laptop

A 120Hz display is one of those laptop upgrades that spoils you fast. Scrolling feels snappier, animations look cleaner, and after a while even dragging windows around can make 60Hz feel sluggish. There are good reasons refresh rate can matter more than resolution when motion and responsiveness matter most. The downside becomes obvious once you unplug, because keeping the panel refreshing at 120Hz can draw more power and eat into battery life.
