The SD5200T supports flexible display setups:
- Single Monitor: Up to 5K (5120 x 2880 @ 60Hz) via one Thunderbolt 3 port.
- Dual Monitors: Up to 4K (4096 x 2160 @ 60 Hz) on both monitors simultaneously.
To connect dual displays:
- Connect one display to the DisplayPort++ 1.2 port using a passive DisplayPort cable.
- Connect the second display to the downstream Thunderbolt 3 port using a USB-C to DisplayPort or USB-C to HDMI cable.
Nota: If connecting a DisplayPort++ to an HDMI monitor, a passive adapter or cable is required. DisplayPort MST (Multi-Stream Transport) for daisy-chaining multiple displays from a single DisplayPort output is supported on Windows, but not on macOS.

3.3 Entrega de enerxía
The docking station delivers up to 85W of power to charge your connected laptop. This power output adjusts based on your laptop's needs. Laptops requiring more than 85W (e.g., some 15” MacBook Pro models requiring 87W) will still charge, but potentially at a slightly slower rate. Windows laptops must be designed to support power delivery via Thunderbolt for charging functionality through the dock.
