Hi all
No displayport on external display (tv)
No other display showed in control panel (already did the alt / Check button for searching display)
Neither in system report
Thunderbolt digital video output —> cable —> tv
Tv hdmi ports and cable hardware checked and working under catalina and other computer
Macbook pro 9.2 2012 non retina intel hd4000
Big sur 11.6.7 / open core legacy patcher 0.4.7
Got wifi fw800 usb3 everything working except external display
I can adjust brightness
Post install root patcher says no need to install anything
Worked fine under catalina

Any idea ?
