ASUS RX 580 8gb - framebuffer
Good afternoon I use ASUS RX 580 8GB in Sonoma 14.3.1 (23D60) - and ATY, Yelcho framebuffer. Orinoco is no longer supported. Only the first DP video output works, but I have two monitors and really want HDMI.I made a patch for connectors based on ATY, Yelcho, but the changes are not applied in OpenCore. Perhaps it's not correct. Without a frame, all video outputs work, but I would like to use ATY, Yelcho.
What am I doing wrong???
