HDMI for second Monitor was working, now broken

i5 - 6500 (Skylake)

GA-B150 HD3P

Powercolor R9 390X Devil

16GB DDR4

250GB SSD

Samsung Monitor with DisplayPort, ASUS with HDMI

​

Both Monitors were working with Sound on the HDMI one.

​

So i fucked when trying to do my USB ports and reverted to USBinjectall.kext. Before this I was able to plug in my second monitor with HDMI without problems. Now I can't plug it in without getting a black screen. Where can I start?
