What it means
Overdrive is a monitor setting (sometimes called Response Time, Trace Free, or OD) that pushes pixels to change color faster, reducing the smear — ghosting — that trails behind fast-moving objects. It is about motion clarity, not frame rate.
More detail
There is a sweet spot. Too little overdrive leaves visible ghosting — a dark smear trailing behind moving objects; too much overshoots — the pixel races past the target color and throws a bright halo or corona ('inverse ghosting') onto the leading edge, ahead of the object, which looks just as wrong. …
