Samsung’s DeX software allows you to connect compatible phones and tablets to an external monitor or TV and use your mobile device as a desktop computer.
A few years ago, Samsung also added support for using DeX with a computer so that you can interact with your Android applications on your Mac or Windows PC. And last year, Samsung added support for using DeX wirelessly to stream its content to a compatible smart TV or monitor.
One thing you couldn’t do until recently? Use DeX wirelessly with a PC. But now you can … maybe.
As detected by Android Police, the feature appears to require Samsung’s One UI 3.1 software, which debuted with Samsung Galaxy S21 smartphones, although it may be implemented in older phones in the future.
To use DeX wirelessly with a PC, you will need:
- Download and install the latest version of DeX for Windows or Mac.
- Make sure that Link to Windows is not running on your phone.
- Open DeX on your phone, choose DeX on PC
After doing this, you should see a desktop-like user interface on your computer that allows you to run your Android apps on a larger screen. This can be useful if you want to use a mouse and keyboard for chatting or replying to emails, for example. You can also continue to use the phone while it is connected.
You will probably still have a more stable connection if you use a USB cable to connect your phone to a computer, but Android Police notes that the wireless DeX for PC supports 1080p content without significant input delay.
