Modern-day smartphones are computing powerhouses, but their smaller screen real estate limits what you can get out of all that horsepower. DeX is Samsung’s answer to that bottleneck. Samsung DeX is a mobile desktop solution that lets you turn a PC, a monitor, or a TV into a full-fledged desktop experience powered by your Galaxy phone. The phone hooks up to the PC or monitor with a USB or an HDMI cable, though DeX also wirelessly connects if both devices are connected to the same Wi-Fi network. With the tap of a button, the secondary screen boots to the DeX platform.
You’ll be greeted by a typical intuitive desktop featuring resizable windows, right-click context menus, and keyboard shortcuts. The first-party Samsung apps are already optimized for the DeX experience. Samsung DeX also supports the Chrome browser, Microsoft Office, and some Adobe apps. You can use your phone’s display as a touchpad for DeX. It works with touch and the S-Pen. You can sketch on your phone with the S-Pen and view it on the big screen. You can also use the phone screen and DeX side-by-side. As such, the platform lets you create unique workflows and maximize your productivity. If you bought a Samsung flagship in the last five years, it supports the DeX environment by default, but its connectivity features may vary between models.
