The DPI setting can be changed by holding down the left side button and scrolling the wheel. The color of the NZXT logo changes to indicate your setting. Blue indicates 1600 dpi, purple is 800 dpi, and red is 400 dpi. All in all, the NZXT Avatar S is a pleasure to use and performs as advertised. It feels very precise and the ergonomics are top-notch.
