- Durning installation if you nead ethernet and is disconected use terminal to set proper media type. Script is located under /EFI/network_UP_script
- Display Port Audio output isn't working with enabled internal speaker and lineout / remove alcid=88 in boot args
- Sleep not tested.
- Display flickering gone. This have something with sound, maybe using Skylake HDMI output was the issue. Adding [layout 88] to boot args enabled internal cheap speaker. Sound quality is excelent on external aplifier. After that no issues with powering down monitor, connection, and some sort of digital movements on display. I was literally prepared to check power in monitor :) but this start to work. Sleep is better. Updated Monterey 12.5 (21G72).
