Samsung DeX was released alongside the Samsung Galaxy S8 and S8+. DeX enabled users to use the phone as a desktop computer if they had a monitor, keyboard and mouse. Now, a report by SamMobile states that DeX will soon be getting dual monitor support, possibly when the Samsung Galaxy Tab S4 is released. The Galaxy Tab S4 will be the successor of the Galaxy Tab S3, a Qualcomm Snapdragon 820-powered tablet that was launched in February 2017.
The report states that the Galaxy Tab S4 will indeed support DeX. This would make it the first Galaxy Tab to support it. Samsung will also add the option to use the tablet display as the second monitor when it’s connected to DeX, and the same option will work with phones as well. A tablet display will be more suitable for dual monitor mode because of its larger size.
However, the report adds that it’s not clear yet how exactly dual monitor mode will work with a tablet. The original form factor of Samsung DeX – the DeX Station – and even the new DeX Pad will not be able to prop up a tablet (kickstand) for proper viewing, so SamMobile speculates that Samsung may expect users to buy the Book Cover that will probably launch alongside the Galaxy Tab S4. Any other case of such type would also be sufficient.
With the Android 8.0 Oreo update, DeX gained the ability to use the phone’s display as a trackpad, so it’s natural for Samsung to add the option to use the connected phone or tablet as a separate display. The Galaxy Tab S4 is expected to be unveiled at IFA 2018 in Berlin. SamMobile states that it may be that Samsung will send a software update for the Galaxy S and Note flagships to add dual monitor support. It’s worth noting that the Galaxy Note 9 has been already been confirmed to launch on August 9th, and it will naturally support DeX as well.
