Frequently Asked Questions

Find answers to common questions about SD25TB5 / WD25TB5 with up to 300W Power Delivery

The number of displays that can be connected is limited by multiple factors including CPU, GPU, interface capabilities, and data transfer rates, not just the docking station itself. This is a multi-faceted limitation rather than a single constraint imposed by the docking station alone.
Smart Docking (SD series) is Dell's new docking station lineup introduced in 2025. Building upon traditional docking stations, it adds features such as wireless connectivity and remote management capabilities. Smart Docking can receive firmware updates independently, without requiring connection to a host computer.
