How to use DeX on a spare monitor Julian Chokkattu/Digital Trends The following Samsung phones and tablets are compatible with Samsung’s DeX mode: Not every Samsung device can use Samsung DeX mode, and it’s pretty much restricted to Samsung’s flagship ranges only - which doesn’t include the Galaxy S10 Lite and Note 10 Lite, for some reason. With the new Galaxy Note 20 range, you can even use DeX wirelessly on your smart TV. Instead, it’ll pop up in a separate window, allowing you to use your phone in a desktop environment while also allowing the use of your regular computer. Samsung DeX on the Samsung Galaxy S10 range and newer (including the new Galaxy S20 range) is even more useful, as DeX on those devices is able to trigger within Windows or MacOS - so you don’t need a separate, spare monitor to use DeX. Being able to seamlessly switch from writing an email or document on your phone to writing it in a desktop environment can be extremely useful for some people - and that’s exactly what DeX offers. Of course, many people already have a serviceable laptop, so what’s the point of the DeX mode? In short, it’s the ease of having everything you need in a single device.
