Hi,

Mouse make/model?

Some mice have external buttons that allow the DPI to be selected manually. The Logitech G600, for instance, lets users adjust the DPI from 200 to 8200 from a button located behind the scroll wheel. To determine a hardware-based DPI setting, check the buttons on your mouse

Inexpensive mice typically have a fixed DPI that cannot be changed. Mice with adjustable DPI settings can either be changed through the operating system’s mouse settings or accessed through specialized software that was provided with the mouse. High-end gaming mice usually have customization software provided by the manufacturer. Depending on the product’s specs, the DPI sensitivity levels, report (polling) rate and other adjustments can be changed through the mouse software. In Windows 8, DPI settings for some mice can be accessed through the Microsoft Mouse and Keyboard Center. Check the Keyboard Center or the software that came with your product to determine your mouse’s current DPI setting.  --ehow.com---
