Yesterday I picked up a 2014 15" MacBook Pro Retina. 2.3Ghz, 16GB RAM, 512 SSD, 2GB NVIDIA GeForce GT 750M.

I did a time machine restore from my 2012 MacBook Pro Retina backup to the 2014 Macbook Pro Retina. After the restore I installed 10.9.3 update.

When I connect the 2014 Macbook Pro to my Sony 65X900B 4K TV I'm still seeing 25Hz and 30Hz as options like on my 2012 model. Shouldn't the 2014 model support 4K @ 60Hz with 10.9.3?
 
60Hz is only on MiniDisplay Port, not HDMI. If you're plugging in via HDMI it's only going to give you 30Hz options.
 
Is there a MiniDisplay Port to HDMI adapter that supports 60Hz?

I'm not aware of *any* computer/video card that supports the higher HDMI 2.0 clock for 4k output as of now. 4k TVs really should have DP 1.2 inputs, but that's just another frustration of mine...
 
Even if the Macbook pro support HDMI 2.0, I don't think Sony 65X900B has the HDMI or any input that support 4k@60hz. That's one of the reason why I won't buy the first generation of 4K TV.
 
Not to hijack this thread, but how did you get a 2014 MacBook Pro Retina? I thought the lastest was the late 2013 model? :confused:

Not everyone knows what year their mac came out, or they don't care, so they call it whatever year they bought it in. In this case, that is 2014.

The X900B supports HDMI 2.0. This is not first generation. That is the X900A. I have the X900B which just started shipping last week. The list of supported video signals for HDMI on the X900B.

It was purchased this month. (2014) :)

Exactly
 
Your macbook does not support HDMI 2.0. And actually, it's more up to nvidia to support that... so in that case, the GT 750m DOES NOT support HDMI 2.0. Sorry..
 
The problem is, your 4K display supports HDMI 2.0 but your retina MacBook Pro does not.

As long as you're using HDMI, you cannot enable 4K @ 60 Hz.

Is there such a thing as an HDMI to thunderbolt adapter?

I really want a 4k Dell monitor when it comes out but I assume it'll be HDMI.

There is, but it won't work at 60 Hz, unless you use DisplayPort. Check whether your one has DP or not, and even so, the monitor still has to be able to support 60 Hz itself. The Dell P2815Q 4K display can only support 4K @ 30 Hz.

If you want to buy a 4K display, never ever buy one that only works at 30 Hz.

So far, the only way to run 4K at 60 Hz is to have:
1. A monitor that supports 4K @ 60 Hz with MST
2. A 15" late-2013 rMBP or cylindrical Mac Pro. The 13" late-2013 rMBP is said to be able to support 4K@60Hz as well, but Apple doesn't officially allow that. I don't know whether this is possible over Boot Camp or not.
3. mDP-DP cable

Understood. Hopefully there will be a MDP to HDMI converter that supports 4K @ 60Hz.

The 4K Dells that are already available all have DP and miniDP as well, which suits the MBP perfectly.
 
I just hooked my late 2013 MBP up to my UE48HU7500 using HDMI while running windows and it outputs 3840x2160 @ 60Hz. Would love to be able to do the same in OS X.

I downloaded the latest drivers from Nvida for the 750M rather than using the bootcamp versions.
