Hello!

I have an old Mac Mini 2011 that I upgraded to Monterey thanks to Opencore Legacy Patcher.
It works perfectly with HDMI on a 1080p monitor, but on a 4K monitor it shows a black screen :-(
The signal seems to be received by the 4K monitor, since it doesn’t show ”No signal”.

Does anyone have an idea on how to fix it?

Thank you very much in advance!
