The page "Using 4K displays and Ultra HD TVs with your Mac"says:

"With OS X Yosemite v10.10.3, most single-stream 4K (3840x2160) displays are supported at 60Hz operation on the following Mac computers:"

I remember it is 30Hz, Is it really 60Hz (How can Mac mini and Macbook do 60Hz)?

Thanks!

MacBook, OS X Yosemite (10.10.3)

Apple has announced SST 60Hz for most monitors on certain models and 10.10.3.

But when I try it on my Mac Pro late 2013 and ASUS monitor it won't do 60Hz, only 30Hz.

I guess it's time to call Apple Support.

The hdmi port is v1.4 which is limited to 30p. But, if SST is via Thunderbolt then 60p may well be possible.

Can the Thunderbolt-to-hdmi port use SST?
