KDE Neon, Vega 64 및 Pixio px277h를 사용하여 xrandr이 144hz 설정을 사용하도록 수동으로 시도했는데, 이것이 올바르게 감지되지 않는 것 같았습니다. 모니터에는 144hz 기능이 있고, 포함된 케이블에도 144hz 기능이 있으며(High-Speed로 표시됨), Vega 64에는 HDMI 2.0이 있으므로 하드웨어 측면에서는 문제가 없습니다. 자세한 내용은 다음과 같습니다.

cvt의 정보와 addmode 입력 옵션이 있는데 왜 사용할 수 없나요? 이 문제를 어떻게 해결할 수 있나요? 이 비디오를 바탕으로 Vega 그래픽 카드가 2560x1440 및 144hz를 지원할 수 있다는 것을 알았습니다. https://www.youtube.com/watch?v=cB5RRdTi9bY
