    The diagonal is the number used to describe the size of the screen. The most popular sizes are 24 and 27 inch screens.

  • Response Time (GTG)

    The time it takes for a pixel to change from one shade of gray to the next. A low response time provides faster response to our actions (input lag) and a cleaner image (less ghosting) which are important in gaming. Response times below 5ms are considered acceptable, but for gaming, monitors with 1ms are recommended.
