Mini DisplayPort adapter for Mac and PC

The Jansicotek adapter converts a Mini DisplayPort or Thunderbolt output to an HDMI female port. It is intended for users who need to connect a laptop or desktop to a monitor, TV or projector using an existing HDMI cable. The 0.5 ft white cable keeps the link short for a tidy desk setup.

Gold-plated passive converter with triple shielding

Gold-plated contacts and a gold-plated shell resist corrosion while the triple-shielded cable reduces interference. The passive design draws power from the source Mini DisplayPort and does not require an external supply. It transmits both uncompressed 7.1 or 5.1 audio and video in a single direction.

4K 30Hz limit and single-display operation

The HDMI 1.4 port caps 4K resolution at 30 Hz while 1080p and 720p run at 60 Hz. DP 1.2 on the source side supports the required link rates for these modes. The adapter cannot drive multiple monitors or work bidirectionally, so builders needing multi-stream output or reverse connection must choose a different device.

Questions about this item

How do I plug the Mini DisplayPort end into a Thunderbolt port without forcing it?

Align the connector with the Thunderbolt port on a 2010 or later MacBook and insert straight in; the gold-plated shell seats without an audible click, so stop when the metal shell sits flush.

Will the gold-plated contacts need cleaning or replacement over time?

The 24k gold plating resists oxidation; occasional dry contact cleaner on the Mini DP and HDMI ends restores conductivity if the signal drops after years of use.

At what resolution does the link drop from 60 Hz to 30 Hz during long sessions?

The HDMI 1.4 female port caps 4K x 2K at 30 Hz; sustained 4K output therefore runs at 30 Hz from the first frame, not after a thermal limit.
