Steam Deck Docking Station specs and third-party dock compatibility
Valve’s Docking Station connects a Steam Deck to a TV or monitor over DisplayPort 1.4 or HDMI 2.0, with three USB-A ports and Gigabit Ethernet. Below are its specifications and what to look for in a third-party dock.
| Connectivity | |
|---|---|
| Display outputs | DisplayPort 1.4, HDMI 2.0; up to 4K 60 Hz or 1440p 120 Hz; FreeSync (VRR)[1] |
| Multi-monitor (MST) | Supported; currently needs both HDMI and DisplayPort in use[1] |
| USB | 3× USB-A 3.1 Gen 1[1] |
| Ethernet | Gigabit[1] |
| Power | |
| Power | USB-C PD passthrough input; PSU included (1.5 m cable)[1] |
| Physical | |
| Deck connection | Captive 6-inch USB-C cable, low-profile 90° connector[1] |
| Dimensions | 117 × 29 × 50.5 mm[1] |
| Weight | approx. 120 g[1] |
The dock works with both the LCD and OLED Steam Deck. In Gaming Mode the Deck’s own screen turns off when an external display is connected. Using both screens at once currently means switching to Desktop Mode.
Third-party docks and hubs
Valve says most USB-C compliant docks and hubs work. The specific points:
- Power: to charge the Deck, the dock needs USB-C Power Delivery passthrough. Some docks reserve part of the power for their own ports, which can trigger a “slow charge” warning.
- Thunderbolt and DisplayLink docks may work but aren’t officially supported.
- DisplayPort-to-HDMI needs an active adapter or cable. Passive ones aren’t supported.
Firmware updates
Valve’s procedure for making sure the dock has its latest firmware: plug the power supply and Deck into the dock, restart the Deck, unplug both, wait 10 seconds and plug them back in.
Picture problems: Steam Deck external display not working.
