My widescreen worked fine in Mojave.
Looks like it is not supported by Catalina. The highest resolution available is 1920x800, which is way lower than my screen is capable of.
I am using Mac Pro (Late 2013)
I followed the "alt" suggestion above too ("alt" is the "option" key on the MacBook keyboard), and chose the 3840 x 1600 (low resolution) option, which is the U3818 native resolution. This seemed to restore the display to the previous resolution I used with Mojave. If any anomalies are observed with this setting, please post them here.
Parallel Toolbox doesn't propose the 3840 x 1600...
I got this weird issue... :
For both I use the DELL WD15 dock.
Funny thing, plugging directly with the usb-c adapter works...
And we got no answer for months on that topic ><
What a user experience...

“I found that you can get it to work by using Parallels Toolbox, using the tool to change resolution to suit the monitor.”

Doing this on VMware Fusion:
Interesting. Nifty workaround, on Parallels’ part I do not use Parallels, so I was not aware of that. My Mac is being serviced right now, so I cannot try that at the moment with VMWare Fusion.
Here is the closest item I can find on VMWare Fusion in accordance is at page 10 of this link: VMware Tools Configuration Utility User’s Guide
A Screenshot of Page 10. It Reads:
So, apparently, for VMware Fusion, that would not work, being that it does not affect the host (the Mac). But I most certainly plan look into it.
DELL U3818DW screen no longer supported.
