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

Big.Lou.

Just to be certain that I understand you correctly. Are you saying that you are able to have 3 desktops running: 1 x rMBP screen, 2 x external displays by using a TB2 port for each external display?

If yes, what resolutions are your external displays running?

Thanks.

Kogir or other forumites:

1) Do you have an idea whether Iris can also output 4K @ 60Hz? Or is this exclusive to the top-of-the-line rMBP sporting the Nvidia 750M?

2) If your answer is yes, then even the lowest 13-inch October 2013 rMBP can theoritically output 4K @ 60Hz. Could you please comment on how the performance would be?

PS. I will be outputing only to one monitor/TV if that makes a difference.

Interesting. I have a late 2013 MBP retina 13" 256/8 with Iris Graphics. I also cant wait to finally purchase an affordable 4k monitor, which i expect to run at 60 Hz.

First thing i am a bit worried about though is the performance of the iris graphics. Do you think it will be able to do 4k Video @60 Hz? That would be really nice.

In terms of ports, Displayport 1.2 integrated into the TB2 ports would work theoretically, but i understand it is not implemented in Mavericks yet, right?

If thats the case, what about Thunderbolt 2 itself? Not sure how the original Tunderbolt display was connected, via Displayport or otherwise?

Good to hear that the standard Iris graphics can output 4k @60Hz. Gaming is not an option sure, but Video (scaled 1080p or 4k) would be important for me. I mean, Apple is advertising 4k through HDMI on these late 2013 MBPs, at 30 and 24Hz. I read that even the mouse would lag at such low frequencies?

Not so good to hear that the necessary Multi Stream DP is not supported in Mavericks. Please Apple, get this fixed until mid 2014! I bought this thing to use it with OS X.

Btw i tried the pich zoom in a pdf directly and through safari on my Iris MBP. Im not an expert, but i didnt really see a lag on the different resolutions (i mostly use the best for retina, the other ones have really quite small fonts and icons on 13" dont they?). I do run Mavericks though, the late 2013s already ship with it pre-installed. So maybe its that OpenCL driver.

Thanks for your reply! Lets hope that the multi-stream DP will be fixed soon.

Btw, i am still wondering why there are (or should be) performance issues with the "scaled" resolutions? I thought the OS would render Icons, text, menu bars etc. depending on the resolution, so best-for retina would have a higher cost than "more-space-1680"?

When it is in "best for retina" mode, it's running at the "optimized" DPI mode that Apple thinks is the best for that display size, regardless of your preferences of how small / large you prefer things to be.

All the icons / UI elements, etc. were specifically designed for this DPI scaling mode....the other, higher scaled modes tax the fake intel GPU more, as they have to adjust the "optimized" UI elements and make them smaller and give you more screen real estate. More screen real estate = more pixels to drive = more mathematical calculations = more taxing on the fake intel GPU (OK it's more like an APU but it's still not a real GPU).

Again, Iris Pro could have fixed this in a heartbeat because of the dedicated 128 MB of eDRAM and Crystal Well design ( for more info about that and why the memory bandwidth of Iris Pro is so much better, read http://www.anandtech.com/show/6993/intel-iris-pro-5200-graphics-review-core-i749 50hq-tested/3 ) but for whatever reason, Apple chose not to include Iris Pro chips as an option for the 13" retina. I don't know why they made this decision.

thanks for explaining. Seems to be quite a shame that they didnt out the Iris Pro on it. Anyway before i bought my 13" a friend of mine told me that his 2012 15" with the 750M was lagging as well.

I knew there would be a price to be paid for having one of the very early retina notebooks. So far i dont have any issues though, so i cant really complain. Now if i can also run my 4k Display next year properly, im happy. (and i dont need the mbp display at the same time)

Hi NiqueXyZ,

I don't mean to hijack this thread... Wondering if you have time to revisit the gmail push/activesync thread from a few weeks back. I'd be grateful for your help -- it's driving me nuts.

Thanks!

Kogir, in Mavericks/Displayport, can you use the Asus as two 1920x2160 screens? (Seems the only big downside is the menu bar would only span half the screen.) If so, can you do it @ 60 Hz?

Thanks so much. 🙂

Thanks so much to both of you - wouldn't it be awesome if Apple sponsored their own compatibility lab? 🙂

I wonder if either of you could check one more Maverick driver question... I have not yet seen any report of someone being able to do 2,560 resolution over HDMI on the Macbook Pro retina 15". We know Maverick drivers support 4K@30Hz, and presumably 1080P, but don't know if the Apple drivers support anything in between. The goal would be to optionally use the HDMI for a conventional 30" monitor.

Unfortunately I don't have a suitable display to test - The monitor would have to support HDMI 1.3 or above, and my Dell 3008WFPs don't.

That said, this was possible on the original rMBP, so I doubt they've removed it.

Hi NiqueXyZ,

Sorry to bug you hear again. None of us have been able to reproduce your results re Gmail/Activesync using the mobileconfig and the UUID we discussed. Wondering if you might be able to paste the text of your mobileconfig file into the thread (minus identifying info) and/or tell us if we're missing a step. Is the only value we need from the old iPhone the value from the metadata plist? I'm assuming we are missing something else that's crucial.

Thank you so much.

Yes, you would need output on both sides.

NO macs support HDMI 2.0 yet.

AFAIK no GPUs support HDMI 2.0 yet.

You could output HDMI over thunderbolt, but you would need to create a thunderbolt GPU first.

AJA / BlackMagic have them I believe -- but they don't have HDMI 2.0 yet...the HDMI 2.0 standard was just ratified in September.

Next year it will be the year of 4K displays and HDMI 2.0 TVs and Monitors / Displays.

@johnniecache: that's what I'm trying to find out - so far I only found a 30(!!) Euro adapter on eBay. Ships from China and... just does not seem all too trustworthy. It claims to support 3D and 4K, but then again it could only support 3D- and 4K-enabled HDMI-Cables and only 1080p-Output? This is starting to confuse me ;-)

@NiqueXyZ:

• My TV is a Hisense... I really don't think they will be so gratefull, but I might give them a call to ask for that
• So over the TB2-Port you're able to output more than 30Hz (since 2009 / 2010), correct? That's great news, since 30Hz is nice for watching a movie, but everything else is just too laggy. That means the only thing missing is a cable/adapter (TB2 > HDMI2) aaaand a TV/Display with HDMI2 or a DisplayPort1.2... well alright. Seems like we're trapped on both sides at the moment ;-)

This is starting to get clearer.

I still can't get over how blind-sided the entire industry was by this... 4K @ 60Hz by 2014 - wow, none of us ever saw that coming. Honestly, this is the first time in 25+ years I have to buy a new computer just to use a state of the art display. What ever happened to putting in a few years of future proofing?
