I have a Late 2013 MacBook Pro with NVIDIA GeForce GT 750M 2GB graphics card running macOS High Sierra 10.13.1, and when I attempt to connect 3 4k screens (2 Mini DisplayPort, 1 HDMI) while running the internal screen, all screens go blank, and the system freezes until I hold in the power button to force power off.
Things I've tried:
- Using just the 3 4k screens without the internal (this works, but doesn't allow me to use the internal)
- Using 3 non-4k screens (1080p + 2k + 2k) and (1080p + 4k + 2k) with the internal (this works)
- Using 1080p + 4k + 4k + internal (this crashes the system)
- Unplugging one screen after it freezes (system is still frozen)
- Checking the logs (couldn't find anything (maybe I'm looking in the wrong place), and there's no kernel panic log)
- Plugging in the 3 screens and then opening the laptop to turn on the internal screen (Freezes like before)
- Booting with everything plugged in (It just doesn't finish booting)
- Booting to recovery with everything plugged in (gets stuck on the apple with progress bar)
My computer has no trouble with the 3 screens without the internal (low CPU, not running slow), so it doesn't seem like it's just getting overloaded.
I know this computer can drive 4k screens and can also drive 3 externals plus the internal, but maybe I'm hitting some undocumented limit here by trying to combine them. Is there anything else I can try or somewhere I can look to see what the error is?
I'm considering getting a 4k compatible USB -> HDMI video adapter to drive the screen I won't use as much, but I'm not sure if that will trigger the same issue, and I'd like to see if there are any other ideas.
