AMD HDMI Outputs limited to 30hz at 4K

Just switched off high Sierra and NVidia to a RX570 on Mojave. Butter smooth UI I wish I would have switched sooner. The only gotcha, is that I have a 4x4K setup, 3 displays which are connected via DisplayPort at 4K60 no issues, the HDMI output seems limited to 4K30hz(1080p60 works fine). Both the card and my monitor LG27UD68 say they are HDMI2 compliant. Has anyone been able to get 4K60hz working over HDMI? My NVidia card just had 4 dp outputs so I didn’t have to work around this. The clover/weg args -cdfon enablehdmi20 cause my system to boot to black screens.
