The monitor has two settings for Response Time (under submenu “Display”) accessible via the built-in menu through the bottom right buttons. The settings are Fast and Normal. The specs of the monitor boast 1 ms response time. I have, in no situation, been able to reproduce a 1 ms response time, regardless of game, program, or setting.
