Hi,
I have a mac pro 4.1 updated to 5.1 running Sierra with an AMD RX560, works flawlessly. I have 2 x mac 24" 2560 x 1440 displays connected via Atlona https://www.amazon.com/ATLONA-AT-DP400-Dual-DisplayPort-Converter/dp/B003CWEXWO adapters.
After upgrading too 10.14.4, both displays are black, in normal boot or safe boot.
If i connect a non apple display 1920x 1080, i get picture.
How or why does the current setup work on Sierra but not on Mojave?
Any help would be much appreciated?
