If you’re like most gamers, you probably use your PlayStation 4 controller for more than just playing games. You might use it to navigate your console’s menus or to control your PS4’s media player. But what if you want to use the controller as a second screen for your computer? There are a few ways to do this. The simplest is to buy a USB gamepad adapter like the one from Amazon.
