Q: Dual 4k support for MacBook Pro Mid 2014

I have a thunderbolt docking station with gigabit ethernet, USB mouse, keyboard and headphone connected to the 2nd thunderbolt, while the first one has 4k@60 connected to it.

Shouldn't that mean a hard disk would also work?

I can confirm the exact same....  I now have one times expensive paperweight!

I just wanted to added my results to the thread in hopes that it helps others...

My system:

MacBook Pro (Retina, 15-inch, Late 2013)

NVIDIA GeForce GT 750M 2048 MB

OS X Yosemite (10.10.1)

Dell P2815Q

I've connected two (2) of these Dell P2815Q displays at 3840x2160@30Hz (DisplayPort to Mini DisplayPort). I'm very happy with the results.

@mach11: Are you running these at a scaled 1920x1080 (HiDPI) resolution or are you using the full 3840x2160 native resolution?

I have the 15" rMBP w/ NVIDIA (Mid 2014) and I'm looking at a similar dual monitor setup and I want to run them in HiDPI mode.

Right now I'm in between getting 2 Dell 24" (P2415Q) or 27" (P2715Q) UltraHD 4K displays. I believe I could run 2 of either of these models at a scaled 1920x1080 @ 30Hz (HiDPI) resolution. If so, then I only have to decided between 24" or 27" ... decisions decisions

Thanks in advance!

I own the LG 34UM95, which runs at 3400x1440, and have now ordered the P2715Q.  I hope to have them both running at 60HZ on my late 2013 rMBP.

Dell arrives Saturday, and I will be reporting my results here.

I own the late 2013 15" rMBP with Iris Graphics, running Yosemite 10.10.1

I just bought a Dell P2715Q 4K (3840x2160) monitor and I am running in on DP/TB port and getting 60Hz.

I already owned an LG 34UM95 34" widescreen running at 3440x1440 and it is also running at 60Hz on DP/TB port.

I have attached a pic I took today from System Report which shows the monitors, their resolution and their refresh rate.  This is a gorgeous setup and it's working great for me.  Highly recommended, if you have ~$1,400 to throw at two monitors.

Larrysing,

This is great and specific. Thanks for posting. Is your Dell P2715Q at 60hz running in MST or SST mode?

Sean

SST mode.

Hello,

Thanks for clear answer I have additional question, could you tell us about fans in your rMBP ? They go crazy on this setup or not ? In normal work, not gaming

No, they really don't.  I use a secondary app to control fan speeds, and I also have the rMBP sitting on a fan-powered cooling mat, which I just bought.

They ramp up a little if I am running full-screen 4K video on the P2715Q, but I don't do that often.  If you were going to run full-screen 4K video all day long, then you might have a problem.  Generally, they stay under control.  For just general office work like spreadsheets and browsers, the load does not tax the fans much at all.

Ok, it's nice. Thank for answer

Per larrysing's post, I literally just picked up a P2715Q this week and am loving it. I have a late 2014 MacBook Pro (fully decked out but not the top-top CPU). I am not noticing much fan activity but when I play video in HD or 4K video for more than a minute or two, the fans do spin up and I do feel the laptop get a little warm (but not hot). Although that happens, that does not surprise me much and I almost expect it given how many pixels the graphics chip is pushing to both the laptop screen and the 4K monitor.

Hi Stephane,

Did you updated your OSX to 10.10.2?

I have problem with my rMBP 13 mid-2014, CPU i7, Iris display. Cannot support 4K resolution with Dell UP2414Q. See below image.

Did someone have same problem too?

Thanks all, Stanley

Someone can help to resolve this?

Thanks, Stanley

Hate to break it to you but I believe (although I could be wrong) the 13-inch does not support 4K the same way the 15-inch MacBook Pro does. See here:

Are you using an HDMI cable or DisplayPort? If not using HDMI, you might want to try it. Or, per the link above, you may need to research what the necessary "hacks" are to get 4K working, perhaps at 50hz. I know SwitchResX is a common tool to make finely-tuned adjustments to the display output settings, including resolution, retina density, and refresh rates.
