Have you ever wanted to stay productive working on your phone by using a bigger screen such as on your PC Monitor or on your Big TV?

Yes, you can connect your Samsung phone that comes with Samsung DeX feature to watch a very detailed image or videos by connecting a type-C to HDMI cable to the Monitor or large TV for detailed latency display quality. You could also connect your phone to TV wirelessly via Wireless DeX.

This DeX feature allows you to enjoy a clearer view in Samsung’s Desktop mode called DeX. You can perform multitasking with Office tools and much more with a huge screen.

Samsung DeX / Wireless Dex feature is available on:

  • Galaxy S9, S10, S20, S21 and newer,
  • Note8, Note9, Note10, Note 20, and newer Note series phone,
  • Z Fold series phones,
  • Galaxy Tab S4, S5e, S6, S7, and newer S series tablets.

How to Set up and why use a DeX cable or HDMI cable instead of DeX Wireless?

How to Setup DeX cable or HDMI cable to your Monitor or TV?

  • You need to connect a standard “USB-C to HDMI” cable to a monitor or TV to start DeX.
  • For the first time using DeX, a pop up message will display on your Home screen and tap Continue to start and allow Full Desktop mode.
  • Another popup will appear on the notification panel to ask you whether you want to “Use your phone as a touchpad” acting as an easier cursor navigation.
  • To Exit DeX, you can turn off DeX by tapping on the bottom left corner to Exit DeX.

You need to be aware to save all of the changes made while using DeX, because if you unplug the HDMI cable the DeX will restart

Why Do We Use DeX Cable or HDMI Cable to connect DeX instead of Wireless DeX?

Since most of the content on your phone will need to travel wireless to your Smart TV, thus this would require higher latency speed for smoother video or media consumption which can only be achievable when using a cable connected DeX. However, if you are using Wireless DeX, minor youtube, web browsing and office words consumption would be smooth without any issue.


Samsung Wireless DeX is only supported on Samsung 2018 TVs or newer TV, and on other branded smart TVs that support Miracast technology. It is recommended that some 2018 TVs may get better display results by using cable HDMI connection for DeX.
