Hi,
Is it possible to drive an UHDTV 4K display with the newly released Macbook Pro (22nd October 2013) Retina display with NVIDIA GeForce GT 750M installed ?

Yes. Either use a mini display port (thunderbolt) to hdmi cable or use an Apple TV if you want to do it wirelessly (airplay).
traceur333's answer makes no sense.
Has anyone actually hooked up a 4K display to the rMBP HDMI port? To the Thunderbolt 2 port? On the 15" rMBP? On the 13 rMBP?
Let us know your experiences--which displays, performance, ...
Thanks.
Yes I agree this does not anwer my question. If it does I actually would like to understand why.
The rMBP technical description does not list the HDMI version supported unlike the MacPro that says it will support HDMI version 1.4
HDMI version 1.4 and 2.0 are the only version supporting 4K screens. HDMI 1.4 will suport a 4K screen @ 30fps and HDMI 2.0 will support a 4K screen @ 60fps. If the HDMI version is lower than 1.4 on the lastest rMBP forget it, it won't work.
a 4K TV is 3840 x 2160 pixel
For example the Sony 4K TV will suport 3840 x 2160/24p or 24fps

Can the latest rMBP support that and why ?
No you're right. I read it wrong. My bad.
I assume the tech spec mentioning HDMI support of UHD at 30fps implies HDMI 1.4 support on all of the rMBPs.
I am also interested to know if the Thunderbolt 2 port will support UHD monitors at 60Hz, particularly on the 13“ rMBP.
It would be great to have early rMBP and UHD folks report their experiences.
Thanks for starting this thread.
Yes as you said it might do but because Apple does not make it very explicit unlike for the MacPro (supports up to three 4K display) makes you wonder where is the catch. Spending £2,199 in the new rMBP and another £3,600 for a 4K screen to find out it does not work is not something I would like to try although I will be able to provide the answer to this post. 🙂
Can not understand why Apple support is not stepping in with answer instead of letting their customers work out what the answer is ? At the end of the day until I have the answer I can not make up my mind on what I am going to buy.
I'm also confused... I guess my question is "Does the new MBPr 15" w/ 750M support 4K displays via the TB2 port and if so, at what refresh rate (eg. 60Hz?). I am assuming the answer is "NO" based on reading between the lines in the following links. However, I do not see any thing directly addressing the capabilites of the TB2 port.
Link 1.. http://www.apple.com/thunderbolt/
Now with Thunderbolt 2 built into the new Mac Pro and MacBook Pro with Retina display, you can connect the latest 4K desktop displays and get double the bandwidth for your peripherals. And the two generations of Thunderbolt technology are compatible with each other.
Link 2... http://support.apple.com/kb/HT6008
4K Ultra HDTVs using these configurations are supported via the HDMI port:
- 3840-by-2160 resolution at 30Hz
- 4096-by-2160 resolution at 24Hz Note: Mirroring is not supported when using this resolution.
Link 3... http://www.apple.com/macbook-pro/specs-retina/
Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors
HDMI video output
- Support for 1080p resolution at up to 60Hz
- Support for 3840-by-2160 resolution at 30Hz
- Support for 4096-by-2160 resolution at 24Hz
Apple does not have an official answer for this question. I've brought up this question on multiple forums and no one has both a 4K display and a new rMBP to test out if the new rMBP will support 4K at 60Hz through thunderbolt 2 (not HDMI as the new rMBP definitely is HDMI 1.4a and only support 30Hz). I spoke with a senior engineer (it took going up the rung three times) and have a case opened to answer this issue.. the question is now going up to product engineering to find out the answer.
I am thinking that if the rMBP TB2 ports do support 4K at 60Hz, maybe Apple wants to wait until it introduces its MacPro and perhaps its own TB2 4K display. This would be a killer offering--the MacPro for 4K creation, and a rMBP that you could plug into a 4K display for an incredible desktop environment along with a best-of-class notebook.
Make any sense?
But then why mention 4K at all for the rMBP?
Good point. I was thinking that HDMI 4K at 30Hz is a different class of hookup, and not really all that relevant (unless you want to hook up a $699 Seiki 39" UHDTV which only supports 30Hz.
But we know that TB2 supports 4K at 60Hz. Not sure if when combined with rMBP display it overloads the Intel GPU. But then again two external 2560x1600 are almost the same pixel count as one 4K display, so it the spec that, it should be able to drive a 4K display.
A 4K TB2 display just makes a lot of sense given that Apple has a 27" TB display now.
I guess we'll find out in a couple of months.
Thanks all for your input
My conclusion at the moment is the rMBP with 750M supports
3840-by-2160 resolution at 30Hz HDMi 1.4a is good enough to do any type of Video work
The following video is interesting http://www.youtube.com/watch?v=Wa-DRVqPJRo as the Asus PQ321Q is actually working on two independant video signals input. The driver need to be able to merge those to make it a single screen. Not sure the rMBP driver will be able to take care of this.
If anybody is wondering, the first genration 2012 Retina MacBook pro 15" with Nvidea 650m also supports 4K when running Mavericks.
The resolutions available when connected to my Sony 55X9004 are:
3840x2160p 24hz
3840x2160p 25hz
3140x2160p 30hz
4096x2160p 24hz

I have tested the suprising power of the first generation Retina Macbook with 2.6ghz i7 and 16g ram and have found it can handle an 80mpbs 29.97fps 3840x2160p video on the hdmi display, while playing back a 1080p bluray rip on the main display. I would recommend propping up the laptop up on something to help airflow as it really heats up with this test.
Performance with Quicktime playing the videos is good, but there are a few dropped frames when moving windows around the screen or using Mission Control.
Performance with VLC 2.1.1 playing the videos is slightly better with the setting tweaked for maximum performance, zero dropped frames when watching a 4k video, frames only drop when moving windows or using Mission control.
The Apple support page lists only the 2013 MacBooks, but this confirms that a 2012 MacBook can handle it as long as it has the Nvidia graphics.
Have you tried Display Menu from the App Store? It makes all of the actual supported resolutions by the Retina display available.
This is what resolutions are available on my 13" rMBP 10,2 (Late 2012).
Actually I just purchased the Seiki 4K 32in in from Amazon for $405. It does work just fine with the 15 in macbook Pro retina at 3840x2160 at 30Hz, but only through the thunderbolt port wiht an active minidsp to HDMI adapter. Apple apparently blocks the HDMI conector at 24Hz for that kind of resolution.
