Written by: Emma Morris


What is Samsung DeX? Samsung DeX is a game-changer for mobile-powered desktop computing.


In a nutshell, Samsung DeX transforms your smartphone into a near-fully functioning desktop PC.

Keen to know more? Stick around, and let's unbox this marvel together.

Remember, if you're in the market for a Samsung phone to kickstart your DeX adventure, ur.co.uk has got you covered. With a 12-month warranty, and a bunch of extras, you're set for a top-tier experience.

Key Takeaways

  • Watch it turn your Samsung phone into a makeshift desktop computer.
  • You’ll need hardware, like a DeX station or HDMI adapter, to set it up.
  • With DeX, you can run full versions of Android apps on a larger screen.
  • You can exit DeX mode with a simple click. No fuss.

How Samsung DeX Works

Samsung DeX isn’t just a fancy name or an aesthetic logo. It's an entirely separate platform that boots up when you plug your Galaxy smartphone into a compatible monitor or TV.


Think of it as your phone putting on a suit and tie, ready to crush that PowerPoint presentation.


What gets it working? Usually, a DeX station or a Dex HDMI adapter is your go-to gadget.


These devices serve as the bridge between your smartphone and your external display. By plugging your phone into one of these, you activate the DeX interface.

Differences Between DeX Adapter vs DeX Station

Whether it be a DeX Adapter or DeX Station - Both aim to deliver a desktop experience that can potentially turn your Samsung smartphone into a primary computing device.


But how do they different?

What is DeX Adapter?

A DeX adapter is the lightweight champ. It's got a USB-C port that links up with your Galaxy phone and an HDMI port to connect to a monitor.


With its no-frills method, it's a straightforward way to activate DeX mode.

Also! DeX adapters are compact and travel-friendly, making them ideal for the hustle and bustle of life.

What is DeX Station?

The DeX Station is what you'd call the do-it-all marvel.


Along with the standard HDMI port and USB-C connection, it sports additional USB ports and even an Ethernet port.


That means you can hook up an external keyboard, a Bluetooth mouse, and other peripherals, transforming your Samsung phone into a veritable workhorse.

Setting Up DeX With Hardware

For most cases, you'll need some hardware to set up your DeX environment.


That could mean a DeX station and adapter, or even a standard HDMI cable and a USB-C cable - Either way,  all these devices support Samsung DeX.

  • To connect using external hardware, attach the DeX device to your external monitor's HDMI port using the DeX cable or a standard HDMI cable.
  • Then, connect your Samsung phone via the USB-C port.
  • Afterwards, your phone should boot into DeX mode.

But wait, your DeX experience continues beyond visuals. Your next step involves dancing your fingers over a Bluetooth keyboard and mouse.

  • Just sync these gadgets with your Samsung phone, and consider your setup complete.
  • Alternatively, those favouring a traditional approach can opt for wired companions, connecting a USB keyboard and mouse.

Want an alternative? The mobile or web versions of most apps you love are optimised and accessible in DeX, allowing you to make the most of that larger screen and external keyboard.

Wireless Connection to Samsung Smart TVs

Imagine a world where cords are ancient history. With Samsung's Smart TVs, you can dive into the DeX universe without a tangle of wires.


  • For this wireless magic, first, ensure your Samsung smartphone and Smart TV are on the same Wi-Fi network.
  • Then, swipe down from the top of your phone's screen to reveal the quick settings menu.
  • Tap "DeX", and your phone will search for compatible devices.
  • Select your Smart TV from the list that pops up.

You're in! Your Samsung Smart TV screen will now morph into a DeX interface.

To navigate, use your phone as a touchpad or connect a Bluetooth keyboard and mouse for that full desktop experience.

Just remember, your phone and TV should be relatively new models, as some older Samsung Smart TVs released before 2019 may struggle to support DeX wirelessly.

Samsung DeX's Best Uses

You're well-versed in Samsung DeX—its purpose, setup, and essential equipment. The real kicker is pinpointing the ideal moments to unleash this Samsung innovation.

Increase Work Productivity through Mobile Device

Hate juggling between your phone and desktop computer at work? Samsung DeX lets you streamline your workflow by mirroring your phone screen onto a larger display.


Emails, PowerPoint slides, Microsoft Office Suite—they all look and feel better when you're not limited to a small mobile screen.

And for those deep into the Google ecosystem, Google Play Store apps run smoothly in this desktop environment. That means you can seamlessly slide into Google Sheets or Google Docs without logging into a computer.

If you're a "pen and paper" kind of person, Adobe Acrobat Reader and DeX pad also allows you to annotate PDFs with ease, without the added fuss of scanning and sending documents.

Add the external keyboard into the mix, and you're looking at the prime setup for ticking off those work tasks.

Your Personal Entertainment Hub

Who says Samsung DeX is all work and no play? For media buffs, this tool is a treasure trove.


While your phone's USB-C port is occupied, just connect Bluetooth peripherals for an immersive audio experience.


You can watch YouTube, stream Netflix, or even indulge in some light gaming with Dex optimised mobile apps and screen mirroring mode.


It's a brilliant way to consume media when you're travelling but don't want to carry around a laptop.
