Dell SD25TB4 Pro Thunderbolt 4 Smart Dock

The Dell SD25TB4 is a Pro Thunderbolt 4 Smart Dock that converts a compatible notebook into a fully featured desktop hub through a single Thunderbolt connection. It expands both screen real estate and peripheral access, making it easy to step away from the limits of a laptop and work with a multi-display, wired-network setup.

For visual workflows, the dock can drive up to four external monitors. A single 8K panel, dual 6K screens, or a mix of QHD displays are all possible through dual DisplayPort 1.4 outputs, an HDMI 2.1 port, and a USB-C connection that carries DisplayPort 1.4. Designers, analysts, and video editors who need large, detailed workspaces will appreciate the crisp resolution support and smooth refresh rates.

Connectivity goes beyond displays. Two Thunderbolt 4 ports move data at up to 40 Gb/s while delivering 15 W of power to accessories. Four USB-A 3.2 Gen 2 ports and a USB-C 3.2 Gen 2 port handle high-speed storage or input devices at 10 Gb/s. A 2.5 GbE RJ45 interface provides a dependable, low-latency network path for video conferencing, cloud collaboration, or large file transfers.

The dock supplies up to 130 W to supported Dell laptops, so systems stay charged even under heavy workloads. Non-Dell notebooks receive up to 96 W, enough for most high-performance machines. IT teams can push firmware updates or carry out remote troubleshooting through Intel AMT, even when the host PC is powered off, reducing downtime in managed environments.

Whether you set up a permanent workstation in a corporate office, rotate through hot desks, or build a streamlined home office, the SD25TB4 keeps cables under control and devices connected. It fits professionals who rely on multiple displays, creators who shuttle large media files, and anyone who values a tidy, efficient workspace that can be re-docked in seconds.
