With the Note10, DeX now supports a new mode that lives inside your operating system so that your phone's and computer's features can co-exist on the same screen. At first, the system required you to connect your device to a dock, but has since evolved to forgo that requirement and work directly when plugged into a monitor with a simple USB-C to HDMI cable. Samsung DeX is a neat way of turning your phone or tablet into an actual computer.
