Dell Precision 3560 docking stations: choose for 65 W, 90 W or 130 W

Which dock options should you consider?

Dell documents WD22TB4, WD19S with the 180 W supply, WD19TB/TBS and WD19DC/DCS in single-cable mode for Precision 3560. Those are the practical starting choices. WD19S with the 130 W supply, UD22 and HD22Q are marked unsupported for this model; do not treat their USB-C plug as sufficient evidence.

Connect displays and power

Computer cable

Use the dock's specified Thunderbolt/USB-C cable in the Precision 3560 Thunderbolt 4 port that Dell marks with Power Delivery. The manual distinguishes that port from the other Thunderbolt 4 port; do not assume both accept charging.

Display cables

Start with one monitor on a direct dock HDMI or DisplayPort output. Add the next screen only after the first reaches its required mode. The laptop's HDMI 2.0 port is useful for an isolation test.

Power

Read the wattage on the original Dell adapter: the model was offered with 65 W, 90 W and 130 W USB-C supplies. Compare that with dock host delivery, not merely dock-brick wattage.

Display ceiling

An exact combined dock display ceiling was not established in the reviewed Precision 3560 documentation. Keep requested resolution, refresh rate and each cable path explicit.

First recovery steps by symptom

The dock works, but the laptop does not charge

1. Move the host cable to the Thunderbolt 4 port Dell marks with Power Delivery.
2. Check the original laptop adapter for a 65 W, 90 W or 130 W rating and compare that with dock host delivery.
3. Confirm the dock has the specified AC supply; use the original supported charger if the dock cannot meet the requirement.

USB or Ethernet works, but the monitor is blank

1. Reduce to one monitor and one direct dock video cable.
2. Test the same monitor and cable from the laptop's HDMI 2.0 port when the monitor has HDMI input.
3. If direct HDMI works, return to the dock path and check its video cable, selected monitor input, firmware and graphics driver before adding another screen.

Nothing on the dock works

1. Verify dock AC power and reconnect the manufacturer-specified host cable without extensions.
2. Try a known-good USB accessory on the charging-capable Thunderbolt 4 port.
3. Only after cable and port isolation, use Dell's exact-model support page to check current BIOS, Thunderbolt and graphics updates.

Still unknown: Dell's reviewed documents do not establish every exact display count/mode for each supported dock, nor whether a lower-power arrangement will sustain an exact workstation load. Monitor, cable, firmware and workload results remain untested here.
