Recently, the company has announced that you will no longer need a separate monitor like a TV, keyboard setup, and HDMI cable to enable the desktop environment with Samsung DeX. Instead, you can now use Samsung DeX on compatible Galaxy devices on Windows or Mac with a charging cable also.

What is Samsung DeX?

Samsung DeX is a software interface that activated by plugging a compatible mobile device into a spare monitor, laptop, or computer. It runs on all of the flagship smartphones that Samsung has launched since 2017, including the Galaxy S8 or later (mostly S and Note Series).

However, Samsung launched DeX for PC in August 2019. It helps users to connect their mobile device to a Windows PC or Mac compatible so they can use DeX right from their laptop.

Why Use Samsung DeX on Laptop?

Samsung DeX has many different features that best suit your needs. Samsung DeX Mode allows your device to display a PC-like experience on a large screen with the same apps that you use on your phone every day. Finally, you can use DeX mode on your monitor while using different apps on your device at the same time, or turn your device into an input device to control the DeX environment.

Benefits of Using Samsung DeX on Windows/Mac on Samsung Galaxy:

  • Easy file transfers between Windows and Dex.
