MacBook Pro & External monitor

[kart]

I have a mid-2014 15" MacBook Pro hooked up to a 4k monitor via Mini display port to display port cable.
I know that my MacBook Pro can run the monitor @ 3840x2160 @ 60HZ, however is there anyway to check that I am in fact getting 3840x2160 @ 60hz and not 30hz?

I ask this as many of the cables I have seen advertised say that they can only output up to 1080p.
I want to make sure that I am in fact getting 3840x2160 @ 60hz

Cheers

If you're using mini DP to DP you won't have any problems. it's only an issue with HDMI, as certain older cables/ports cannot support 60Hz 4k [including the MacBook USB Type C multi adapter]

I have seen some mini display to display cables that state that they only output up to 1080p.
Some things feel a little slower (mouse movements) on the monitor, hence why I am trying to find out if it is running @ 60hz or 30hz

Also audio doesnt seem to work from the monitor when it is hooked up with mini DP to DP cable..
