The original Samsung DeX lets you get a PC experience by connecting your eligible Samsung Galaxy smartphone to a display or TV with just an HDMI cable or USB cable. But with the new feature called “Wireless DeX,” you can now bring productivity to the big screen wirelessly. You don’t need any accessories such as a USB cable or HDMI. So, in this guide, you will learn how to use Samsung Wireless DeX on your TV.
However, Samsung Wireless DeX is a great way to experience a desktop-like interface offered by your Galaxy device. All you need to do is connect your mobile device to a monitor or TV that supports Miracast and a keyboard and mouse and launch Samsung DeX.
Wireless DeX is one of the most important new features of One UI 2.5. This feature lets you display your phone screen to a supported TV or monitor and then use your phone as a touchpad to control the TV with multi-finger gestures.
Furthermore, you can swipe up to view recently opened apps with three fingers to control inputs on the TV screen, swipe down to return to the home screen, or swipe left or right to switch between apps. To permit customizations for different display sizes, you also get some screen zoom and font size choices.
