4k TV plugged in - Catalina boots to black screen (Windows works well), RX590

Out of fun, I plugged in my 4k TV to see how it would work as a monitor.

MacOS Catalina 10.15.3 booted into a black screen (but it seemed to be alive). Windows worked just fine.

GPU: RX 590

On a daily basis, it's working fine with an HD monitor.

Any ideas what might have caused this?
