    Dual HDMI ports both cap out at 4K@30Hz — this is not a bandwidth-sharing limitation but a hard spec ceiling on both ports independently, regardless of how many displays are active. Requires a host laptop with MST support (Windows/ChromeOS) to drive both displays as extended desktops; macOS treats the second display as a mirror only.
