10 | About your monitor

*The 1 ms gray-to-gray mode is achievable in

the Extreme mode to reduce

visible motion blur and increased image responsiveness. However, this may

introduce some slight and noticeable visual artifacts into the image. As every

system setup and every gamer's needs are different, Alienware recommends that

users experiment with the different modes to find the setting that is right for

them.
