USB-C does not describe one capability
Two identical-looking ports may support different data rates, charging, and display output. Check the laptop manufacturer documentation before selecting a dock.
Count displays and resolution together
A dock may advertise multiple ports while limiting the total resolution or refresh rate. Some operating systems also restrict independent external displays on particular laptop models.
Budget the power correctly
Dock input wattage is not always the wattage delivered to the laptop. Subtract the power used by the dock and attached devices, and confirm the included power supply.
Include cable placement
A short captive host cable can determine which side of the laptop the dock must occupy. In a small workspace that can obstruct the mouse or charging route.
