Your calculated eDPI is:
800
eDPI (effective Dots Per Inch) is a single value that reflects your mouse pointer speed by combining your hardware DPI and in-game sensitivity.
Use the formula: eDPI = DPI × Sensitivity
eDPI = DPI × Sensitivity
Example values used below: DPI = 800 and Sensitivity = 1.25.
800 × 1.25 = 1000
eDPI is the product of your mouse DPI and in-game sensitivity. It standardizes sensitivity across different hardware and settings.
Not necessarily. Optimal eDPI depends on personal preference and playstyle. Use it to match feel across devices rather than as a quality metric.
Set DPI and in-game sensitivity so their product equals the target eDPI. For example, 800 DPI × 1.25 sensitivity and 400 DPI × 2.5 sensitivity both yield eDPI 1000.
