Got to go.
(Gray To Gray) A unit of measurement of pixel speed. Used to measure the response time of gaming monitors, GtG means how long it takes for the pixel to go from one gray level to the next. GtG is not a standard metric because vendors measure levels differently. Other metrics are BwB (black-white-black) and WbW (white-black-white), all of which are not standardized and can be misinterpreted. See adaptive sync.
