What this adapter does

The Jansicotek adapter connects a Mini DisplayPort or Thunderbolt source to an HDMI display. It supports 4K x 2K resolution at 30 Hz and passes uncompressed 7.1, 5.1 or stereo audio. The 0.5 ft cable is triple shielded with gold plated contacts.

Resolution and refresh limit

The HDMI side follows version 1.4, so 4K x 2K output is capped at 30 Hz. Higher refresh rates such as 60 Hz at that resolution are not supported. Full HD 1080p and 720p signals work without restriction.

Direction and power

The adapter is unidirectional: Mini DisplayPort input to HDMI output only. It draws power from the source port so no external supply is needed. Buyers who need bidirectional switching or a longer reach will need a different solution.

Questions about this item

What resolution and refresh rate will I actually get from the 4K x 2K rating when I plug this adapter into my display?

The adapter supports 4K x 2K at 30 Hz, plus 1920 x 1200, 1080p, and 720p; 60 Hz at that resolution is not supported.

Which DisplayPort and HDMI versions are used, and what do they limit in practice?

Mini DisplayPort 1.2 feeds the link; HDMI 1.4 on the output side caps 4K at 30 Hz and handles 1080p at 60 Hz with 7.1 audio pass-through.

How much space does the 0.5 ft cable need behind my laptop or monitor?

The cable is only 0.5 ft long, so it needs very little clearance and suits tight desk setups or side-by-side ports.
