What should I check before buying a USB-C dock?

[Dave]

USB-C docks can look very similar, but the laptop’s USB-C port may not support video output or charging at the same level as the dock. For a setup with two monitors and a wired keyboard, mouse and network connection, which specs are worth checking first? I’m especially interested in avoiding a dock that limits display resolution or can’t provide enough power to charge the laptop.

Check the laptop’s specs for USB-C video output and charging support, then compare those with the dock’s supported displays and power delivery. For two monitors, check that it supports both at your monitors’ resolution and refresh rate. Also make sure it has the wired ports you need.

What laptop model and monitor resolutions are you using?

Also check how the dock handles two displays: a basic USB-C MST dock may not support two extended screens on every laptop or operating system, while DisplayLink docks need software. Compare the dock’s power delivery with the wattage of your laptop’s charger.
