4k x 2k display users have reported difficulty configuring their high resolution displays @ 60 Hz refresh rate on the E-Port Plus docking station.
The E-Port Plus Dock supports dual 4k x 2k resolution @ 60 Hz refresh rate.
Depending on the capabilities of the system docked, you may only be able to achieve 60 Hz display on one DisplayPort Video port of the dock at a time. This limitation is specific to systems with a Multi-Stream Transport (MST) hub. The system MST hub is the bandwidth limitation for dual 4k displays, not the dock.
Figure 1. - E-Port Plus DisplayPort Connections (Item 2 is DisplayPort Video Port 1, Item 1 is DisplayPort Video Port 2.
The DisplayPort Video ports will only display DUAL 4k x 2k resolution @ 30 Hz refresh rate on MST equipped systems.
If your system is equipped with Discrete NVidia or AMD graphics, then dual 4k x 2k displays @ 60 Hz can be achieved using the E-Port Plus dock.
