Samsung DeX: Everything you need to know


Connecting your smartphone to a computer is nothing new. It’s the fastest way to transfer images and files back and forth by far. However, that’s often where the interaction stops. Enter Samsung DeX. In 2017, Samsung introduced a software platform designed to change how your phone and computer interact. Here’s everything you need to know.

What is Samsung DeX?

Essentially, Samsung DeX is a software platform that extends your smartphone or tablet into a full-size desktop experience. This means you can access key apps and features, but you can control everything from a monitor, using a mouse and keyboard. As you can see above, the interface closely resembles recent versions of Windows but with a decidedly Samsung twist. You can resize the various DeX windows, drag and drop them to your heart’s desire, and use familiar keyboard shortcuts to navigate.

The earliest versions of Samsung DeX required a docking station — either the DeX Station or DeX Pad — to power the software and peripherals. However, in recent years, Samsung has slimmed down the equipment required, moving to an HDMI adapter and a simple USB-C cable. Samsung even added wireless DeX support with the Galaxy Note 20 series launch, though it carries its own set of requirements. First and foremost, you’ll need a monitor or TV with the Miracast feature. It’s similar to Google’s Chrome-based casting feature, though slightly less common.

Samsung DeX is also available for Windows and MacOS. This means you can simply plug your phone into your computer via USB and use the DeX ecosystem. You’ll just need to download the desktop Samsung DeX app. Additionally, larger-screen devices like the Samsung Galaxy Tab S9 series can simply switch to DeX mode, without the need for a secondary monitor.

Something to keep in mind is that macOS support ended in January 2022. You can still use the app, but support and updates are unavailable.

As far as app support goes, DeX is a productivity powerhouse. You can open helpful options like Zoom Cloud Meetings, Skype, Adobe Acrobat Reader, and more. Microsoft’s Office suite also features heavily on the platform, with Word, Excel, Outlook, and PowerPoint.

How do you set up and use Samsung DeX?

There are a few different ways to set up Samsung DeX, and the process depends heavily on your device. You can tap into both wired and wireless DeX setups, so we’ll run through the steps for both methods.

Wired DeX setup

  • Plug your DeX cable of choice into the HDMI port on your monitor. If you’re using a multiport adapter, connect it to the other end of your HDMI cable.
  • Connect your device to the adapter using a USB-C cable. You should see a Samsung DeX logo appear once it is connected.
  • Select your peripherals. If you’re connected through a laptop, you can use your trackpad and the built-in keyboard. If you’re only using your phone and a monitor, head to the Bluetooth settings and scan for connected devices.
  • Also, if you’re connecting to a computer, you’ll need to download the Samsung DeX app for the platform first. Then, simply connect to it using a USB cable.

That’s all there is to it. Once you have a connected device and peripherals, you should be able to get up and running quickly. You may also want to keep a wireless charging pad nearby in case you burn through your battery.

Wireless DeX setup

  • Enter the screen mirroring mode on your TV or monitor.
  • Open the Quick Settings menu on your Galaxy device and select DeX. Now, choose your TV or monitor from the available devices.

That’s all it takes to get your phone set up for wireless DeX controls. Even better, you can continue using your phone while the TV or monitor acts as a second screen. You can also connect your keyboard and mouse directly to the TV to use it as a large monitor.
