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!
'Mac Pro 2013, Dual AMD Firepro D700, El Capitan & Windows 10 BC'
Mac Pro, OS X El Capitan (10.11.5)
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.
The article cited at the top of your posting is the definitive article on this subject.
Given that this display only appears to have HDMI inputs, it makes no sense to wrestle with adapters -- use the HDMI output of the Mac Pro (late 2013) directly, but do not put any other high-speed displays on ThunderBolt Bus 0.
Thanks.
I've tried just the hdmi with no other Tb drives or displays connected and the hdmi is limited to 30hz. The reason for the adapter is that I thought the hdmi may be the wrong version to cope with 4k @60hz but was hoping the mini DisplayPort would do it.
Thanks for your suggestions.
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.
what display?
Apologies, forgot that bit!
It's a TV, Samsung ks9000.
the active adapter is a utap one (does 4k @60hz with a Surface Pro 4 connected to the Samsung and a few other TVs) if that's any help.
