4K @60hz from mini displayport on Mac Pro 2013

If I have an active 4k mini displayport to hdmi adapter can I output 4k @60hz from a mac pro 2013?


The only options I see have a refresh rate up to 30hz.


Any help or information is appreciated!

That adapter you listed and already have does on paper meet the requirements, the Club3D one was I believe the first out and perhaps more widely used.


In theory you should not need to use SwitchResX or similar. There are complicated rules with regards to how many adapters and displays you can connect to a 2013 Mac Pro, however if this is the only display this should be the simplest configuration and not be an issue. See Use multiple displays with your Mac Pro (Late 2013) - Apple Support


Note: The above Apple article does not cover all possibilities.

Yes.


While the built-in HDMI port on the Mac Pro 2013 (and in fact all Macs so far made) is only HDMI 1.4 and therefore limited to 30Hz at 4K, it is possible to buy and use an active Mini Displayport to HDMI 2.0 converter. As the name suggests this converts Displayport to HDMI 2.0 and HDMI 2.0 unlike HDMI 1.4 does support 4K at 60Hz.


This adapter is one that will do the job for you - http://www.club-3d.com/index.php/products/reader.en/product/mini-displayport-12- to-hdmi-20-uhd-active-adapter.html

Thanks John for the clarification with the HDMI port.


I have this adapter http://www.uptab.com/minidisplayport-thunderbolt-to-hdmi-4kat60hz-adapter-cable- gold-plated.html which seems to have the same spec as the link you kindly posted.


Do you think I would need to use a programme like switchresx to enable the 60hz or do you think is this something El Capitan supports natively?


Thanks.
