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

I've tried to follow the conversation and maybe I'm not understanding something, but I have the sharp 4k monitor and my macbook pro (15" latest edition) seems to drive it adequetly (through the display port or hdmi), the problem for me and what makes it unusable is that for some reason browser pages load very slowly while surfing the internet. Surfing the internet is 5X slower on the sharp monitor than it is on my macbook pro. I run a lot of other apps (terminal/coding type) and they seem to load/refresh fine, its just the internet is slow. I've been keeping the macbook monitor open to run the browser and doing everything else on the external monitor. It didn't do this on the apple hd monitors. Does anyone know why the internet is slow on the 4k monitor? Any solution?

UPDATE:

After doing some tests I found that the internet using firefox funtions normally. It is only chrome that is running slow over the 4k monitor/macbook pro using 3840 X 2160 reosolution at 30 Hertz refresh rate. I really depend on chrome though, does anyone know why this is or a possible solution?

Whether it's the version of Haswell that's two chips in a multi chip module (MCM) or not. However, even the single chip version seems capable of advanced graphics, so that doesn't tell you much. But if it's a quad core chip, it's definitely two chips in a package:

Given that eDP is embedded displayport, they must be imagining some really high end tablets. 🙂

I agree it does seem contradictory. But on the other hand, nothing would stop Intel from creating variations on the chips that might limit some of their abilities, even if it's artifical. So it's hard to say which statement would hold more weight.

But if someone tries it on a low end Macbook Pro, that would seem to be the most definitive answer. 🙂

Thanks for the links guys. I've gone through all of them and it seems the models of the Haswell rMBP subjected to this test have not been indicated in those links.

Confirmations from Haswell rMBP owners who happen to have 4k 60Hz monitors would be greatly appreciated. Please kindly indicate which particular Haswell rMBP you own.

Thank you, Kogir. I did not think that screenshot was taken by you.

I guess 11.3 was a typo?? Did you mean the Haswell 13.3, if so which particular model? According to the first page of this thread you seem to own the high-end 15.4 inch Haswell rMBP with Nvidia 750M GPU. That's why I am confused. Which monitor did you try it by the way? Because, if you got this refresh rate with the high-end rMBP, then the fact that Khaos Tian could not get it with the same computer can only be attributed to different monitors. Or perhaps either you or Khaos disabled the 750M and got 60Hz through the Iris Pro.

Fair enough. (Nonetheless I'd love to hear Kogir's and Aron77's comments because Khaos Tian's youtube videos demonstrates a very laggy 4k @60hz performance on Haswell 750M rMBP)

Isn't there a single Haswell Iris 13'' and Haswell Iris Pro 15'' rMBP owner who also has a 4k 60Hz monitor that may check if they get 4k @ 60Hz, at least on Windows??

but thats exactly what the post says, no?

"The next factor is whether your GPU can drive that many pixels, and I want to say that for most Macs going back as far as 2008, it actually can"

Sure, drivers must be ready too, but they seem to be on the way, right?

Scary!

I'm hoping it will work by the time 10.9.3 is finalized only because if Windows can do it I'm not sure why OSX can't.

I have the Iris gpu which according to the tech specs, it supports 4k at 60hz over DP 1.2. Which is why it works well on Windows 8.1 but let's see if Apple enables it. My monitor doesn't ship until 4/14.

One update on my new Dell UP2414Q monitor. The issue with video/display artifacts has completely disappeared in the past couple of hours. I am not sure what I did but it may have to do with moving the primary menu bar around in the display preferences (the Dell is curently the primary display). Regardless, the monitor is now functioning perfectly without a single issue in 1920x1080 Retina mode (in 4k @ 60hz of course)! I will try and replicate whatever I did to resolve this and keep the thread posted.

Yep, I'll test it tonight when I get home and update this post.

I tried searching as well, it doesn't seem widespread, Intel's official site just states it's up to the manufacture to determine the max resolutions due to the various variables involved with bringing 4k and the various hz configurations.

I'm hopeful because if it can drive the 4k at 30hz, then MST should bring it to 60hz. I don't have a good understanding if MST is demanding, but from what I hear it's like running 2 screens at 1920 x 1080 at 60hz or something.

You have to admit that it's fairly unlikely that the kind of person who would pay so much for an early 4K monitor would buy a computer system with no GPU, or have a reason to try to disable their GPU. Even now, with Intel's integrated graphics being OK, I'd be squeemish to risk a no-GPU system. Even on the laptop I carry around all the time.

What do you exactly mean with "squeamish" and overall? What kind of risk can happen? Do you think 4k 60Hz can burn an Iris or Iris Pro equipped rMBP or something?

Bad news.

MBP retina 13 inch haswell.

Enabled dp 1.2 on dell.

went to native resolution, it's at 30hz.

Like others have said, Iris isn't made to run this resolution. Chrome was laggy in rendering, might be a chrome thing.

Tried the 1920x1080 scaled resolution and that scaled resolution would break the display and the monitor would respond with no input source. Other scaled resolutions worked fine.

I'll probably be returning this.

What's going on??

johnniecache has asked the following question to tomengland but it is not available in the thread:

"Did you configure the MST? This must be done in the DELL's display settings! DP 1.2 regular 4k through HBR2 is definitely not working yet, but this may change at some point as well.

I really find it hard to believe that Multi-stream Transport is not possible, because 2 individual displays 2560x1600 will work at 60Hz."
