Mini DisplayPort 1.2 to HDMI adapter

This 20 cm adapter connects a Mini DisplayPort 1.2 or Thunderbolt 2 source to an HDMI display. It transmits both audio and video, supporting resolutions up to 3840x2160 at 30 Hz and 2560x1600 at 60 Hz. A separate HDMI cable is required for the connection. Compatible devices include various Apple MacBook, Microsoft Surface Pro, Lenovo ThinkPad and Dell XPS models.

Bandwidth and resolution limits

The adapter operates at up to 3.0 Gbps with a 300 MHz TMDS clock rate. This bandwidth caps 4K output at 30 Hz or 24 Hz depending on the exact resolution. Higher refresh rates such as 60 Hz are only available at 2560x1600 or lower. The link is unidirectional from the Mini DisplayPort source to the HDMI display and cannot be used in reverse.

Gold-plated contacts and portable build

Gold-plated connectors provide corrosion-resistant contact surfaces for reliable signal transfer. The short 20 cm cable keeps the adapter lightweight and easy to carry in a laptop bag. Power is drawn directly from the Mini DisplayPort side, so no external supply is needed. The HDMI female port accepts any standard HDMI cable the user already owns.
