Compact 0.8ft 4K Adapter

This 0.8ft Mini DisplayPort to HDMI adapter connects legacy laptops and desktops to modern displays. It serves users with pre-2017 MacBooks, Surface Pro models through Pro 6, and select ThinkPad, Dell XPS, and Alienware systems that only offer Mini DP or Thunderbolt 1 and 2 outputs. It is not for buyers whose source device uses Thunderbolt 3, Thunderbolt 4, USB-C, or standard DisplayPort.

Uni-Directional Build Fit

The active converter plugs directly into a Mini DP or Thunderbolt 1 and 2 port and requires no external power or driver installation. Gold-plated connectors and a braided cable resist wear during frequent plugging, while the short length keeps the signal path clean for 4K at 60 Hz, 1440p at 144 Hz, or 1080p at 240 Hz. It frees up no additional ports and cannot be used in reverse from an HDMI source.

Audio-Enabled Single Cable

The adapter passes 7.1 and 5.1 multi-channel audio alongside video, including DTS-HD and 3D surround formats, eliminating the need for a separate audio cable. Packaging includes only the converter itself; no driver disc, no software suite, and no additional cables are bundled.
