34" Ultrawide (3440x1440) monitor - which chipset?

Hi,

Can somebody please confirm which DisplayLink chipsets support a single ultrawide monitor running 3440x1440 @60Hz (it's a Samsung LS34J550WQUXEN if anyone has one)?

I think I've come to the conclusion that I'm going to need a dock with the DL-6950 chipset from reading the documentation here:

https://support.displaylink.com/know...lution-support

However, the user manual for the Lenovo Hybrid dock (which has a DL-6950) seems to suggest that it only supports a refresh rate of 30Hz despite supporting 5k @60Hz! This can't be right can it?

I'm also wondering whether I can get away with a lower chipset (e.g. one of the DL-5xx0 chipsets)...

Also, is any of the above affected by the port used to connect to the dock with? I'm specifically wondering whether I'd have any problems with the above monitor over a USB 3.0 connection (as opposed to a USB 3.1 (USB-C) or Thunderbolt connection) as while two of the three machines I intend to use this setup with have Thunderbolt connections, one only has USB 3.0 (a Surface Laptop 2).
