I worked with 2 additional screens for a month
worked great
this morning I plugged in the usual setup (only the USB for the adapter)
and it doesn't show the 3rd screen
it does display on the displays that I had an additional 2 screens
I did try to switch cables
and adapter (not the only one in the office)

did a clean install with the app
I tried to install it again

no display on the 3rd screen

definitely something on the software
