CPI and DPI buttons on mouse

• Use of DPI button on mouse.

DPI is the standard used to measure the mouse sensitivity, expressed as the number of DPIs (dots per linear inch) that a device can detect. By changing the DPI, you can instantly adjust pointer speed for precision tasks, such as in-game targeting or photo editing.

• Use of CPI in mouse.

Use the CPI button to confirm changes made and the scroll wheel button to cancel changes. ExactSense will adjust the Counts Per Inch (CPI) of the mouse, which determines the mouse's “sensitivity”. Raise the CPI, and the cursor on screen will move farther with the mouse.

 •°• Technically, the correct nomenclature would be CPI, but instead, the term DPI is more widely used.
