Hi
As the title says, I have the following setup: Macbook pro 2018 - Mojave 10.14.5 - DisplayLink 5.1.1 - Asus mb169b+
I also tried Mojave 10.14.4 with both DisplayLink 5.1.1 and 5.0.1
No one software combination made my Asus mb169b+ monitor work.
It's connected using an original apple thunderbolt 3 to usb/hdmi adapter.

As shown in the screenshot, my macbook recognizes both the Asus monitor and the DisplayLink driver.

Also, DisplayLinkDriver extension is loaded.
The problem is that I can't even turn on my monitor, the power light keeps flashing so it's recognizing the power source, but can't turn it on and use it. It's also worth mentioning that I turned on it by a few seconds but even turned on it hadn't displayed nothing.
I also attach the information collected by the DisplayLink information software.
Please let me know if any other information is needed
