Hello again MaLd0n,
I have replaced my EFI folder with the Olarila folder for the 300 series motherboard and applied a video patch. I am still having some issues. Sleep still does not work correctly. The machine POSTs and the login screen pops up but the screen flickers on and off. No workarounds resolved this issue. I am still having the green screen issue mentioned in the first post. The port is still being recognized as a Display Port instead of HDMI. I even tried an all data patch. Nothing has resolved this issue. Graphics acceleration is working correctly.
