Confirmed with

  • Notebook (generic)

    Video ports are HDMI, DisplayPort, and VGA — one of each, not two DisplayPorts as some listings imply. A single display reaches 3840x2160@30Hz; connecting a second drops both to 1920x1080@60Hz, and all three at once drop further to 1600x900@60Hz. macOS lacks MST support, so all connected displays mirror the same image instead of extending.

  • Steam Deck

    A user resolved intermittent HDMI resolution issues with this hub on a Steam Deck by switching to a higher-wattage USB-C power supply (65W); the underlying power supply, not the hub, was the root cause.
