Samsung Galaxy DeX transforms compatible Galaxy smartphones and tablets into a desktop computing environment, enabling users to run mobile apps on a larger screen with keyboard and mouse support. This solution bridges mobile convenience with desktop productivity, ideal for professionals, students, or anyone needing expanded workspace functionality. The system supports both wired connections (via USB-C to HDMI adapters or docking stations) and wireless setups (for compatible monitors), with newer models like the Galaxy S25 offering enhanced wireless capabilities through Miracast.

Key takeaways from the available sources:

• DeX requires a compatible Galaxy device (S8 or later, including Note series and select tablets) and a Windows 10/11 PC or external monitor ^[1][4][10]
• Setup involves downloading the DeX for PC app, enabling DeX mode on the mobile device, and connecting via USB or wirelessly ^[1][3][7]
• Users can multitask with up to five apps simultaneously, manage files between devices, and use peripheral inputs like Bluetooth keyboards ^[3][6][8]
• Wireless DeX is available for monitors supporting Miracast, while wired connections require specific cables or docking accessories ^[4][7]
