The Anker 575 USB-C Docking Station can handle multiple monitors, but there are some important limits if you're aiming for 4K resolution. It has two HDMI ports and one DisplayPort, so you can connect up to three monitors at once. But, according to the manufacturer's description, it delivers 1080p@60Hz across all three displays, not 4K.
For macOS users, it's worth noting that the dock runs in Single-Stream Transport (SST) mode, which means all your connected monitors will show the same content, not separate, extended displays. We found this out based on our research and feedback from users.
Windows users generally have better luck, as the dock usually works for extended desktop setups with up to three monitors, provided your device can handle it. A lot of folks mention that it's pretty straightforward to set up.
That said, there are some reports of issues like flickering screens or inconsistent resolutions, particularly when all three displays are hooked up using the HDMI ports.
As for 4K resolution, the dock isn't quite cut out for running multiple monitors at 4K. It can only support 4K on a single monitor at a time. If you're really set on having 4K across multiple monitors, you might need to look at other docks that are better suited for that task.
To avoid headaches, make sure your laptop's USB-C port supports DisplayPort Alt Mode; that's crucial for getting video output through the dock. Compatibility can be hit or miss depending on your hardware, which is something other users have pointed out.
In a nutshell, the Anker 575 USB-C Docking Station is a good option if you're happy with a multi-monitor setup at 1080p, but it's not the answer for full 4K on multiple screens at once.
You'll want to set everything up correctly and confirm your device's compatibility to get the best out of it.
