E-Port Plus and 4K Displays

4K x 2K Display Configuration on E-Port Plus Dock

4k x 2k display users have reported difficulty configuring their high resolution displays @ 60 Hz refresh rate on the E-Port Plus docking station.

E-Port Plus Dock

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.

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.

Display Resolution (Standard 60 Frames per Second Refresh Rate)	Maximum Number of Monitors Based on Display Port 1.2 Bandwidth
1680 x 1050 (WSXGA)	5
1920 x 1080 (1080p) or 1920 x 1200	4
2560 x 1600 (WQXGA)	2
3840 x 2160 (UltraHD, 4K) or 4096 x 2160 (4K x 2K)	1

NOTE: When using a single 4k x 2k display, DisplayPort #2 (closest to the center of the dock), is the recommended port.
