4K Display and Retina MacBook Pro 13"

Thanks so much for all the help. I'll post back with results if I get a new 4k anytime soon...

Hi,
With the 2013 13-inch Haswell rMBP it is possible to run at 3840x2160 or 1080P HiDPI over DisplayPort at 52Hz. This is because the max clock rate for the 13-inch over thunderbolt 2 is 450 MHz.

To get this resolution, use the settings in the screenshot I've made with switchresx (attached).

If you want 60Hz or even higher HiDPI settings, you can do this via picture by picture mode with a DP and a HDMI connector. There's an extensive thread on this in this forum.



Edit.. And yes, I did this with the same monitor you're using!

Is there a big difference between 53 Hz and 60?
 
Yes, this is a good device for the next 5 years.
Do you think (all forum users please) this descripton to get 3840x2160 at 60 Hz with a rMBP 13inch late 2013 will be possible for the NEC or other 4K displays like http://www.asus.com/Monitors_Projectors/PB287Q/
This was not restricted to the Samsung U28D590D?

Not possible.

It's a hardware limitation with the U-series of Haswell processors that is used by the rMBPs.
 
Important message. Thank you.

In addition, the mDP to DP and mDP to HDMI adapters are important components with sufficient bandwidth I suppose.
As pre-requisit I have ordered cables with high resolution (4K for DP and 2560x1600 for HDMI) and decided to find out wether or not 52,5 Hz and the Samsung display itself will satisfy.

I will report soon.
 
I haven't found too much of a difference between 52 Hz and 60 Hz for every day tasks–– looks great, much nicer than 30Hz!

And yes, 52 Hz max is a hardware limitation of Haswell U-series.
 
I am running mine at 50Hz as well (which is standard PAL refresh rate). I can't really notice any real difference between 60Hz and 50Hz.
 
I'm very excited to get my monitor purchased and set up. Hoping that many new additions to the market this fall will drive down the price of the NEC. I'd guess that an updated TBD would bring all other 27" and under models under $1000.

I have now the U28D590 to complete my Retina Macbook Por late '13 (TB2) connected with Display Port v1.2 cable 14€ (mDP to DP cable http://www.amazon.de/gp/product/B008XTW666/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) to get 52Hz (sufficient compared to 60Hz) with SwitchResX for photo editing and video usage.
Absolutely fine this brilliant screen.

Thank you all for your contributions (special thanks to jonisign and w0rd3r).

Outstanding feature: Yosemite Support for HiDP usage...

The highest settings I was able to achieve on the U28D590D is the following:

3840x2160@53Hz (with reduced blanking)

Unfortunatelly all the scrolling/zooming/etc. features in Safari and Finder seems to be optimized to work supersmoothly at 60Hz, and this seems to be hard locked and does not depend on the actual beamsync of the display. So at 53Hz you will get some judder during scrolling no matter what.

If you want to simulate Retina 1080p at 60Hz, you can do the following:

- create a 3610x2030@60Hz physical resolution.
- then create a 3840x2160 scaled resolution.

This way the graphic card internally will render everything at 3840x2160 and then map it to the 3610x2030 output. The 3840x2160 scaled resolution's HiDPi/Retina equivalent will be 1920x1080.

The result will be a 60Hz 1080p retina screen, which will be somewhat less sharp (since it is mapped to a 3610x2030 output, which is then stretched by the display to full 4K), but the result is still quite nice, and scrolling will be butter smooth.

It turns out that you can get 4K@60Hz on Windows using Intel's driver and its collage mode using a U28D590D (or other displays which have PBP - Picture by Picture - function). Essentially it is a trick - you need two HDMI cables (or one DP and one other HDMI). The driver splits the screen into two, and sends one half through HDMI1, the other half through HDMI2 (1920x2160@60Hz each). The display then merges the two separate streams into one screen using the PBP mode. The two separate streams are presented to the OS as one display of course.

It would be nice if to have the same solution working under OS X. I use my MBP mainly in docked mode, and I would not mind to attach two cables to the display. This way we could get real 4K@60Hz on rMBP 13.

With this trick even the previous generation Intel HD4000 can output 4K@60Hz.
 
Well, I see that it is possible to configure the two halves of the display as 1920x2160@60Hz, but there is no way to merge them together to act as one single display in OS X. :(

It's true, only possible to do two halfs at 60Hz.

Or, full 4K at 52 Hz, but you can't get any of the HiDPI scaling options. I'm sure that the 13 inch MacBook can handle them if it can handle two tiles at these high internal resolutions. Unfortunately, I contacted Apple and their engineering team confirmed that they will not enable HiDPI options for this model. :(
 
Help!

I tried the exact same settings from post #4 but SwitchResX says "not installed" after restart.

I have OS X 10.9.5 and a rMBP 13" Late 2014. 1080p HiDPI @30 works via SysPrefs.

Any ideas?
 
Got it!

Just to help others:
1.) Reinstall SwitchResX when above error occurs (I used AppCleaner to remove any remains)
2.) I had to enable Displayport 1.2 (1.1 was default) support on my monitor first (else you get black screens)
 
Hmm i tried 2 half trick but wont work. The maximum i get for each screen is just 30hz. Im using up2414q monitor from dell. Any idea?
 
Okay, I have a late 2013 13" rMBP, I was able to get 51.7Hz on the Samsung 4k monitor using switchresx settings from this thread with no problem at all, first try. But, I returned it (couldn't stand the non-IPS display). Now I have the 4k 24" Dell UP2414q. However, the same switchresx settings that worked to get the higher refresh rate are now not working. (I made sure that DP 1.2 was enabled on the monitor) With some playing around with switchresx, I was able to get PAL 50hz to engage but the problem is that even though everything on screen shows that 50hz is enabled, the monitor refuses to actually display in 50hz, it will stay in 30hz. I can't get it to budge.

Another weird thing is I tried to create a custom HIDPI 2560x1440 scaled resolution but that won't work either. Even weirder, is that if I switch to portrait mode, there is a 1440x2560 HIDPI option available by default!

I reset the monitor settings and I reset switchresx and still nothing.

I have both the 13" late 2013 rMBP (issued from school for testing so I'm forced to have it) and a mid-2012 15" rMBP that I had prior to starting school. I'm so frustrated at this point I'm about to just buy the refurbished late 2013 15" rMBP for $1529 from Apple's website so I can get 4k at 60hz and sell my mid-2012 15" rMBP. I honestly think that, at this point, this is my best option. I'm just not sure what I can get for my mid-2012, a couple hundred dollar hit is much better than dealing with this headache lol.

Correct. Those custom res wont work on UP2414Q. I tried it before then gave up and return. Too much hassle. Even 4K 30hz wont be good. Once to run 4K video on big screen the whole OS slower down alot.
 
Has anyone tried with the NEC 24" 4k monitor? If that one won't work with the 13" rmbp, I suppose I'm resigned to living with my crappy old 20" dell until I can upgrade everything with the next broadwell refresh.

I have little interest in chasing tech, but this is all kinds of annoying....
 
Any thoughts on running this monitor on a new iMac with retina display? I just ordered a new retina iMac and I currently have an external 27" Cinema Display and I saw this minitor at a local store on sale for $550. I was really tempted to buy it.

Just wondering if I should still buy it to replace my cinema display and be totally 4 & 5k.

Thoughts?

UPDATE: I just received my retina iMac today and I purchased the Samsung U28D590 4K display and I'm very happy to report that it works perfectly on the iMac. No issues whatsoever in Yosemite, and the iMac sees it at just another retina display!! Yes it's an TN panel and nowhere as nice as the IPS of the iMac but still a great value if you want to be 4K all the way.

Hello everybody,

I have read this forum and purcased an UP2414Q

And it appears that I should have read until the end :confused:

I have just assumed that your tweaks works for this particular monitor too.

But I should have read rayGcon and Malandra's messages.

Anyway my system is

Macbook Pro Retina 13" Mid 2014
Dell UP2414Q ( D.P. 1.2 enabled )
OSX Yosemite 10.10.1

And I can't get anything else than 30Hz also, whenever I try your tweaks with SwitchResX I also get a blank screen. Please let me know if any of you succeded to run this one over 30Hz.

Thanks a lot.
