Morning, fellas.

I've had this problem for a month now, just getting around to asking you guys about it.

I've got a High Sierra hackintosh with the radeon 6870 Reference card. The DVI Ports work fine, I'm using it with one monitor, and the HDMI USED to work fine on my 42" Samsung.

However, about a month ago whenever I try to use the HDMI output it scrambles the video output for the whole system. If I unplug it it goes back to normal. I don't recall changing any settings, so I really have no clue why it started doing this all of the sudden. It does it when I reboot the Computer with the HDMI Plugged in as well.

I've tried the ATI Boot flags and using the DuckWeed Framebuffers. I'll post ScreenShots of my settings here.

I don't want to spend the $ on an HDMI to DP adapter if I can avoid it.

Any help is greatly Appreciated.

Thank You.

Edit: Updating with my hardware added to my user profile.
