Samsung DeX will reportedly receive dual-screen capabilities
Samsung’s desktop crossover software, DeX, is set to receive dual-screen support according to sources speaking to SamMobile. DeX currently runs on the Galaxy S8, Galaxy Note8, and Galaxy S9 by using the vertical orientation DeX Dock or flat DeX Pad to connect the phones to the monitor and peripherals.
When the Galaxy Tab S4 launches, it will be the largest device to support DeX. This makes it better suited to handle secondary screen duties than its smaller brethren. The extra screen could be useful for watching a video while working/browsing on the larger monitor, or for keeping a document open to reference while writing. We would expect the ability to use the touchscreen as a touchpad to be deactivated when in dual-monitor mode.
Samsung is launching a Book Cover accessory that would tilt the display to a better viewing angle, but if the connection is handled from the tablet’s USB-C port then you should get a similar result with any standard case. While there wouldn’t be any technical reason why this dual-screen mode couldn’t also come to Samsung’s phones, we doubt this will happen, since Samsung will likely want to avoid the sub-par cramped experience.
The Samsung Galaxy Tab S4 is expected to arrive in August or September at IFA Berlin 2018.
