The most-asked question
By far: "is it worth paying more for a 120 Hz or 144 Hz screen?" The honest answer depends on whether you do anything that benefits from it (gaming, fast scrolling, animation work) or anything that does not (text editing, video calls, watching films). The 60 vs 120 FPS guide walks through both cases.
