How to Setup Samsung Dex on TV

Are you tired of watching good-quality movies and TV shows on your Smartphone? Now, you don’t have to worry about that because of Samsung DeX. DeX is software that lets you experience desktop view on your phone or TV. All you need is a monitor or TV. The only downside to it is that DeX is available only on Samsung smartphones. So, if you are a Samsung smartphone user, that’s great because you can use DeX and multitask on your TV screen.

Useful Tips When Setting up Samsung Dex Wireless on TV

  • When connecting your phone to your TV wirelessly, it is recommended you have both devices available within a short distance. This is done in order to get a smooth wireless connection and to prevent any lagging or stuttering.
  • Basic operations like navigation and choosing an app can be done easily with the help of a gamepad. But complex operations like pinching two fingers to zoom in won’t work.
  • Trying to access DeX directly from your Samsung TV may not work if your phone is turned off. So, turn on the phone and try connecting again.
  • When you are using DeX, the touchscreen on your Smartphone won’t work.
  • For better navigation, connect the keyboard or mouse to your Smartphone using Bluetooth.

Samsung Dex vs Screen Mirroring

You can view multiple apps, resize windows, and more. You can also view incoming notifications and calls without looking at your phone. Another feature that stands apart is that after setting up DeX, you can still use your phone. This means it gives you a two-way experience.
