MacOS – Does OS 10.9.3 work with multiple external 4k monitors

displaymacbook promacos

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:
