Have a Late-2013 15" rMBP running OS X 10.9.3 with an external 4k-capable Samsung LU28D590DS/ZA.

Whenever I also connect my Dell 30" non-4K monitor, the screen flashes briefly like the machine is acknowledging that another monitor is attached, but then fails to display output to the 30" monitor.

If I unplug one monitor or the other, I can work with either one at a time, but not both.

Is this a known issue with OS 10.9.3 or limitation of my video card?

EDIT: I used the Console application to test output after plugging the secondary monitor in, and got the following output:

Officially, Apple reports that the Retina Display MacBook Pro models can support two external displays up to a 2560x1600 resolution via the Thunderbolt or Thunderbolt 2 ports or one display with a maximum resolution of 2560x1600 via Thunderbolt and one display up to a maximum resolution of 1920x1200 (1080p) via HDMI.

http://support.apple.com/kb/SP690

MacBook Pro (Retina, 15-inch, Late 2013) - Technical Specifications. Display. Retina display: 15.4-inch (diagonal) LED-backlit display with IPS technology; ... on the built-in display and up to 2560 by 1600 pixels on up to two external displays, ..

Mavericks has been know to have some issues with external monitor, most of it was fixed in the 10.9.3.

Set your monitors to correct resolution and try again.

    Buscar...that support article applies to all models before late 2013, which the OP has. Late 2013 MBP's have different tech specs in this regard. For example, support.apple.com/kb/SP690

  • Ah ok, so if I drop the resolution on my 4K monitor, I shouldn't have the issue any longer. Question: would closing my laptop and only using external monitors affect the maximum resolutions possible?

  • good question, I do not know, but would think it is possible since the load to the GPU is lowered ! all you can do is try it :) Please check the answer as done so it does not keep pooping up here forever as incomplete.

  • so I just tried this, and it turns out that setting the monitors to lower, non-retina resolutions does not change whether or not the second monitor is recognized, nor does closing the clamshell of the laptop. As soon as I unplug one monitor or the other, the other one is instantly recognized by the machine; both are plugged into my thunderbolt ports, which is how I had things set up previously. Any other thoughts on why this might be happening?

So it turns out that the Macbook wasn't working with a 4k monitor and a non-4K monitor both plugged into displayports. When I plugged the non-4k monitor into my HDMI port, it worked, albeit at a less-than-ideal resolution.
