Does the new Macbook Pro 15" (late 2013) supports 4K via Thunderbolt/Displayport?

MST *is* enabled in Mavericks, but ONLY on the new mac pro.

This is a driver issue -- the NMP has those AMD firepro whatevers.

As far as why Intel and Nvidia haven't updated their drivers to enable it (for the retinas), I have no idea.

Maybe the performance ***** when you're driving an external 4K display @ 60HZ and the internal retina display at the same time?

Also -- something else I thought to try when I get back into work with the "old" mac pro -- try MST with an NVidia GTX 680.

I bet it will work just fine.

In fact, I will email my NVidia contact and ask him if it works.

EDIT:

Guess not. LOL. They're not going to update the driver to support MST on OS X for the GTX 680. Wow.

Kogir: Try out the 10.9.2 beta. It is reported to include some graphics drivers.

See: https://discussions.apple.com/thread/5475430?answerId=24209998022#24209998022

There is no newer beta.

hmm what about this: http://9to5mac.files.wordpress.com/2013/12/screen-shot-2013-12-19-at-1-07-48-pm. png ? 🙂http://9to5mac.com/2013/12/19/apple-seeds-first-os-x-mavericks-10-9-2-beta-to-de velopers/

But that's not true either! There is no display port 1.2 functionality with the Thinderbolt 2 Ports through OSX. You can only use first gen SST through the TB2 ports... The ONLY way to hook up 4K is through the HDMI port which is only 1.4 (not 2.0). How do u know that there's no support in 10.9.2 Beta? Evidentially there was a new build released today.

He's right, but don't get either Dell - NO MST for the support for the ultrasharp in OS X even in 10.9.2! 30Hz is the worst mistake Dell could have made. Ugh. But Get the Asus! I've been in contact with JJ (Dr. Asus - media relations) and he's confirmed the 60Hz will work with OS X MST and even better it will be out by March - end of Q1! I getting one myself! I'll post up when JJ gives me a date for its release or pre-order. Word up!

samsung 4k monitor released in korea, and price just 599$

support 3840x2160x60hz when DP 1.2 connection.

Macbook Pro retina (LATE 2013) don't support this refresh rate on Mavericks.

But Same machine, Windows 8.1 support it. LOL

FWIW, this could be more than merely a marketing move on Apple's part. If you go back in time a few years, when NVIDIA first launched their 600 series, the hardware supported 4K@60Hz, but the drivers didn't. It took NVIDIA a *long* time to finally get the hack working that combined two virtual monitors into one screen. It seemed to take a lot of work, and other vendors had difficulties as well.

Everyone in the industry might just be waiting to do 4K@60Hz directly, without the two monitor MST hack. Note that this hack would only benefit the highest end late 2013 Macbook Pros - the ones with the the 750 - and I can't imagine there's a lot of volume on sales of that model. It may well be that NVIDIA simply declined to spend the effort needed to make a short-term Maverick MST hack solution for 4K@60Hz for such a small volume - and this might even be the reason Apple went with AMD/ATI GPUs on the Mac Pro - because they were willing to do the Hack.

Personally, I don't understand what makes using HBR mode in a straightforward manner as it stands so diffficult - the bandwidth should be there - but the industry's use of the hack means there must be some issue with it.

I don't see any reason why your statements are not applicable to low-end late 2013 rMBPs, including the 13-inch ones using Iris. If, with the word "hack" you are referring to a firmware/driver update, then your statements are equally true for Intel's Iris and Iris Pro cards. Please see my question and NiqueXyZ's response on page 7 of this thread in this regard. In short he agrees that NVIDIA would not deplete its resources to release new drivers, as supported from NVIDIA's previous stance on GTX680. However he seems to be surprised as to why Intel does not release drivers for Iris and Iris Pro. In any case, he seems to agree with me that it is doable to release drivers for not only NVIDIA 750M, but also Iris Pro and even Iris.

I am now looking from another perspective, i.e. not doability, but whether if releasing any or some of these drivers would cause problems on the part of Apple. That is to say, if 4K at 60Hz is going to be output on late 2013 rMBPs running on Mavericks, then there are potential alternatives needed to be evaluated:

1) Both Intel and NVIDIA may release drivers, thereby making all late 2013 rMBPs outputting 4k @ 60Hz on Mavericks: best option for both Apple and its customers, would not cause any problems.

2) Only NVIDIA may release drivers: this alternative will make low-end 15-inch and 13-inch users having Intel Iris and Iris Pro cards make unhappy, but this option might be acceptalbe to some extent. Both Apple and its customers may think that only the customers paying for the best card can benefit from 4K @ 60 Hz on Mavericks. Nonetheless, Apple might not like this option.

3) Intel may release drivers for both Iris and Iris Pro, and NVIDIA may not release any drivers: This option would make high-end 15-inch users furious and, IMO, Apple would not allow this alternative.

4) NVIDIA may release drivers and Intel may release drivers for Iris Pro only: This alternative will upset 13-inch owners only. This alternative might be acceptable to some extent. Both Apple and its customers may think that only the customers paying for the mid-end and high-end cards can benefit from 4K @ 60 Hz on Mavericks. Nonetheless, Apple might not like this option.

5) NVIDIA may release drivers and Intel may release drivers for Iris only: Providing a feature for low- and high-end cards but not for mid-end card does not makes sense. This alternative would make low-end 15-inch owners furious and, IMO, Apple would not allow this alternative.

6) Intel may release drivers for Iris only, and NVIDIA may not release any drivers: Providing a feature for only low-end card and not for upper segment cards does not makes sense. This alternative would make all 15-inch owners furious and, IMO, Apple would not allow this alternative.

As seen, none of the options without NVIDIA releasing drivers are acceptable to Apple. Hence, if NVIDIA will not be allocatinf resources for releasing new drivers for Mavericks (as suggested by you and NiqueXyZ) then we will never see 4k @ 60 Hz output on Mavericks.

According to http://software.intel.com/en-us/articles/quick-reference-guide-to-intel-processo r-graphics only Intel 5200 (Iris Pro) is cappable of 3840x2160@60Hz

And Intel 5200 Graphics is only available on Intel's Core i7 H-Processors

I have the Iris gpu which according to the tech specs, it supports 4k at 60hz over DP 1.2.

I think this is contentious because there are conflicting Intel documentation in this regard.

Which is why it works well on Windows 8.1 but let's see if Apple enables it.

Have you seen this in person? So far there is no single person, in this thread or elsewhere, has confirmed that they can get 4k @ 60Hz on his Haswell 13'' rMBP with Iris or Haswell low-end 15'' rMBP with Iris Pro via Windows, Such confirmation has only been made by high-end Haswell 15'' rMBP owners with Nvidia 750M.

I tried the Club3D MindDP-to-HDMI 2.0 adapter if that's the one you're seeing on Amazon and it didn't work. I tried SwitchResX to force a 4k@60hz option and all I got was a purple screen with a pink bar across the top. Interestingly, running the TV through the adapter also prevented 4k@30hz from working properly despite the fact that that resolution worked fine over native HDMI.

I can confirm it works in windows 10, the setting is just hidden for me, I have to click secondary minitor > go to display adapter settings > List all modes select from the list. I now works perfectly

You need to enable MST on the monitor itself to get 60 hz

we know that 😉 but you can't enable MST in Mavericks...

I got a NEC EA275UHD monitor with a StarTech mDP->DP 1.2 cable and I'm getting 60Hz SST via the latest MacOS El Capitan

I'm using a Late 2013 mpbr 2.0Ghz / 16GB RAM / Iris Pro

Is MST or DP 1.2 necessary for this adapter? Because, AS FAR AS I UNDERSTAND (PLEASE CORRECT ME IF I AM WRONG), even though this adapter is DP 1.1, according to its specifications it adapts one of the key features of DP 1.2, i.e. HBR2, which is the feature that allows for 4K @ 60Hz. MST is necessary only if you want to realize multiple independent video streams.

See the below link. It says "Compatible with DisplayPort 1.2 High Bit Rate (HBR)":

http://www.accellcables.com/product189.html

If my understanding is correct, all we need is the same version of this adapter with the other end being HDMI 2.0 compatible. That's it.
