VIDEO NEEDS THE RIGHT PATH

that carry a picture.

DisplayPort sockets: 0
HDMI sockets: 2
Video-capable downstream Thunderbolt ports: 0
Ordinary USB-C data-only ports: 0
USB-A ports: 2
Ethernet: Up to 1Gbps

Each display or Thunderbolt peripheral consumes its chosen output. A data-only USB-C socket cannot drive a monitor. Shared bandwidth and actual charging depend on the host and connected devices.

IN THE EXACT PACKAGE

Start with what’s included.

Mini Dock with tethered host cable

Display cables and video adapters are separate. The checker counts them as owned only when you confirm the required quantity and rating; otherwise their cost remains unknown.

No dock power supply or laptop charging is included.

EXACT HOSTS, QUALIFIED ANSWERS

Your computer sets the screen limit.

Our checked host	Native display budget	Remaining conditions
MacBook Air M1 (2020)	One external native display total	macOS 10.12 or later; cable, power and exact timing checks still apply
MacBook Air 13-inch M4 (2025)	Two external native displays total	macOS 15 or later; the finder covers up to two 4K60 routes
Dell XPS 13 9315 laptop	Up to two checked native display routes	Windows 11 with suitable Thunderbolt/graphics drivers, and the required display cables

Displays connected elsewhere use the same native display budget. No DisplayLink workaround is assumed. Other computer models and higher-resolution/high-refresh modes need separate evidence.

Know these limits.

No host charging. Keep your laptop’s separate charger connected if needed.
HDMI output model 500377. DisplayPort-only monitors are not a direct route. New-product reference price is unverified; the maker’s open-box offer is excluded.

Protected streaming needs a verified monitor/cable/adapter/service chain. A native dock alone does not guarantee HDCP playback.
