I have a MacBook Pro (Retina, 15-inch, Late 2013).

Can I use two 3840 x 2160 external monitors over Thunderbolt 2 to HDMI connections if the laptop is in closed-display mode?

I would be perfectly happy with 30Hz refresh rate.

Yes you can for the MacBook Pro (Retina, Late 2013) and later

If you use a 60Hz Multi Stream Transport display with the MacBook Pro with AMD Radeon R9 M370X graphics card only one additional Thunderbolt display is supported.

You can use 4K displays and Ultra HD TVs at the following resolutions and refresh rates via the built-in HDMI port of your Mac:

3840 x 2160 at 30Hz 4096 x 2160 at 24Hz (mirroring is not supported at this resolution)

  • OP asked about the 2013, not 2015. 2013 is NVidia GT750M, dual 2560x1600 max res. everymac.com/systems/apple/macbook_pro/specs/…

  • Thanks @Tetsujin, that site is fantastic, I wasn't aware of it. If you add a short answer I'll accept it.
