If you’re new to PlayStation 4, or just want to get a little more comfortable with the console’s controls, this guide will teach you how to use a mouse on PS4. First, make sure your mouse is compatible with PS4. Most mice work fine, but some may not be supported. If you’re not sure whether your mouse is compatible, check the manufacturer’s website or contact them directly. Once your mouse is ready, connect it to PS4 by plugging in the USB cable that came with it. Once connected, open the Settings menu on PS4 and select “System.” Under “Input,” select “Mouse.” If everything looks good and your mouse is recognized by PS4, you’re ready to start using it! To move around the screen, use the left and right buttons on your mouse to move the cursor around. To zoom in or out of a window, use the up and down buttons on your mouse. To click something onscreen, press and hold down the left button while moving the cursor over what you want to click. To exit out of an application or window, press and hold down both buttons at once until PS4 prompts you to release them. ..
