Unhappy Mojave 10.14.1 Unable to drive two external monitors

I've got a 2018 macbook pro running Mojave 10.14.1 with DisplayLink Driver 4.3 beta (142) and it will not un-mirror the 2nd monitor. I'm trying to run a triple monitor configuration using the laptop and two independent (un-mirrored) displays. The 2nd external display only operates in mirror-mode. The first external monitor works great (unmirrored).

Is there a way to run a triple monitor setup?

I'm using the Siig USB 3.1 Dual 4k docking station. External monitors are both connected via HDMI to the Siig.

Default RE: Mojave 10.14.1 Unable to drive two external monitors

Hi, I'm in the same situation here.
Upgraded yesterday to 10.14.1. I have a Macbook pro 2018 and 2 external monitors DELL P2417H connected via a BELKIN THUNDERBOLT 3 EXPRESS DOCK HD. One monitor is connected via HDMI and the one one via Display Port. The only one working now is the Monitor connected to Display Port. Note that before upgrade it was working from 10.13.6 High Sierra. I tried to installed the latest Display Link stable driver from your site but no luck.

EDIT: I just wanted to mention that the monitor (HDMI on the HUB) not working is not detected by MOJAVE and is going to sleep mode. While the other one is working as expected using display port. And I stress that It was working on 10.13.6.

Anything I'm missing ?

Thanks & all the best,
Frederic

I would stop using the 4.3 driver, update to the 10.14.2 beta 3 and run the 5.0.1 driver.

Any idea if we can still keep 10.14.1 and use 5.0.1 driver ? Or is it advisable to switch to 10.14.2 beta 3 ?

MBP 2018 & MBA 2018 on 10.14.1 with 5.0.1 the display will be black.

With 10.14.2 beta it will work
