최근에 모니터 3개를 데스크탑에 연결하기 위해 새 모니터와 어댑터 케이블을 구입했습니다.
하지만 세 번째 모니터에는 아무것도 표시되지 않습니다.
전원 코드를 교체해 보았고 모니터와 어댑터가 모두 작동하는 것을 확인했지만 어떤 이유로 내 시스템은 한 번에 2개 이상의 모니터를 표시하지 않습니다. 새 모니터가 제대로 작동하려면 모니터 하나만 연결 해제하면 되기 때문입니다. 두 모니터를 모두 사용하지만 다시 연결하면 표시되지 않습니다.
Windows와 Ubuntu를 부팅했는데 둘 다 3개의 모니터 모두에서 제대로 표시되므로 하드웨어 문제나 일반적인 Linux 문제는 아니지만 설치와 관련된 문제인 것으로 알고 있습니다.
이건 정보야
내 주요 모니터 2개는 DVI와 HDMI(HDMI-DVI 어댑터 사용)이고, 세 번째 모니터는 Mini-DisplayPort-DVI 어댑터입니다.
이것은 "xrandr --verbose"의 출력입니다.
