what does dpi mean for a gaming mouse
DPI means Dot Per Inch. In theory, if a mouse has 1600 DPI, then, if you move your mouse one inch (2.54 cm), the mouse cursor will move 1600 pixels. The higher the DPI, the more sensitive the mouse is. That is, you move the mouse even a tiny bit, the pointer will move a huge distance across the screen. Almost all mouse sold today have about 1600 DPI. Gaming mouses usually have 4000 DPI or more, and can be increased/decreased by pressing a button on the mouse.
