The DisplayLink USB Type-A to Dual HDMI Adapter connects up to two 4K (3840 x 2160) 60Hz HDMI displays to a Windows or Mac computer through a single USB Type-A cable, extending or mirroring the primary display. On an M1 Mac mini, combined with its built-in HDMI and Thunderbolt ports, it can drive up to four 4K displays in total. Bus-powered and plug-and-play, it includes a USB Type-C adapter for the bundled cable.
