"Multi-Stream Transport (MST) displays
MacBook Pro (Retina, 15-inch, Late 2013, Mac Pro (Late 2013), and iMac (Retina 5K, 27-inch, Late 2014) computers also support multi-stream transport (MST) displays at 60 Hz. If you use a 60Hz MST display with the MacBook Pro (Retina, 15-inch, Late 2013) or iMac (Retina 5K, 27-inch, Late 2014), only one additional Thunderbolt display can be supported. See Thunderbolt ports and displays: Frequently asked questions (FAQ) for more information on Thunderbolt displays.
You need to manually configure 4K displays to use MST. Follow the steps below to use the display's built-in controls to enable this feature.
Sharp PN-K321: Choose Menu > Setup > DisplayPort STREAM > MST > SET
ASUS PQ321Q: Choose OSD menu > Setup > DisplayPort Stream
Dell UP2414Q and UP3214Q: Choose Menu > Display Setting > DisplayPort 1.2 > Enable
Panasonic TC-L65WT600: Choose Menu > Display Port Settings > Stream Setting > Auto
Your Mac will automatically detect an MST-enabled display. However, your display may require a firmware update to support 60Hz operation. Please contact your display vendor for details. If your specific DisplayPort display is not listed above, check with the display’s manufacturer for compatibility information."
