Checking your mouse's DPI setting is a simple process that can help you optimize your gaming performance and overall computer usage. To check your mouse's DPI setting, follow these steps: Windows users can right-click on the mouse icon in the system tray, select "Properties", then click on the "Mouse" tab and look for the "Resolution" or "DPI" field. On a Mac, go to System Preferences, then Click the Apple logo and select "System Report", type "Mouse" in the search bar, select the "Bluetooth Mouse" section and scroll down to find the DPI value. For gaming mice with adjustable DPI settings, you can often do this through software that comes bundled with the mouse or through the manufacturer's website. Some popular options include Logitech's Gaming Software, Razer Synapse, and SteelSeries Engine.
