Displays

Anker lists 4K at 60 Hz on a single HDMI display, or two displays at 4K 30 Hz using both HDMI ports. Important: on macOS, both external monitors show the same image (mirrored), because most Macs don't support multiple external displays through one connection like this. The laptop needs DP Alt Mode on its USB-C port.

Ports and charging

It adds an Ethernet port, SD and microSD card readers and two USB-A data ports. USB-C Power Delivery pass-through charges your laptop up to 85W (a 100W charger and USB-C cable are required). It supports USB-C, USB4 and Thunderbolt connections on Windows 10 and 11 and ChromeOS; Anker notes it isn't compatible with Linux.
