Thunderbolt 포트가 비디오를 전송하지 않습니다

ubuntu20.04 5.4.0-58-generic을 실행하는 razr Stealth RZ0901952E72가 있습니다. USB-C 포트가 있는 MacBook을 사용할 때 USB-HDMI 케이블을 사용하여 필립스 243V5L을 실행할 수 있습니다. Stealth에서도 동일한 작업을 수행하고 싶습니다("Thunderbolt 3"으로 보이는 USB-C 스타일 포트와 작동하는 HDMI 포트가 있으며 전체 연습의 요점은 두 개 이상의 외부 화면을 실행하는 것입니다). 지금까지는 주사위가 없습니다.

장치가 연결되지 않은 xrandr(및 usbc-hdmi 케이블을 통해 외부 모니터에 연결된 Thunderbolt)는 다음을 표시합니다.

Thunderbolt 포트도 USB-HDMI 케이블을 통해 외부 모니터에 연결하면 동일한 출력이 다시 나타납니다. 즉, usbc-hdmi를 Thunderbolt 포트에 연결해도 아무런 변화가 없는 것 같습니다.

Thunderbolt는 "진짜"인 것 같습니다(Thunderbolt 3를 믿지 않는 경우).제조 사양

추가 인터넷 검색 후 업데이트 - 아마도 필요한 것은 디스플레이 포트용 USB-C일 것입니다.이것이렇게 하면 더 많은 모니터를 얻을 수도 있습니다.
