Are There Any Compatibility Issues Between Specific Monitors and the Dock?

Certain monitors may be incompatible or limited to 4K at a 30Hz refresh rate when connected through the dock’s native DisplayPort output (this is an interoperability issue between the monitor display hardware and a chip in the dock; this issue is not limited to Plugable Thunderbolt 3 docking stations).

The following monitor models are known to be impacted:

  • Asus PB287Q, PQ321Q
  • Dell P2417H, P2715Q, P2415Q, UP3216Q
  • LG 31MU97C-B, LG 24UD58-B, LG 27UD58-B, LG 27UD68-P
  • Philips 288P6LJEB
  • Sharp PN-K321
  • Viewsonic VX2475Smhl-4K, VX43804K
  • Samsung U28E590D

This limitation can be worked around in some cases by changing the monitor’s internal settings to use “DP 1.1”, which will limit the display to 4K@30Hz. The included passive DisplayPort to HDMI adapter can also be used, which will also limit resolution to 4K@30Hz. Alternatively, the display can be connected using a Plugable USB-C to DP or USB-C to HDMI adapter to connect the display (rather than the DisplayPort on the dock), which may allow 4K@60Hz functionality on affected displays.
