HDMI를 통해 nVidia 카드에 연결된 Dell U2515H가 있습니다.
softMCCS를 시도했지만 정상적으로 작동했습니다. 소프트웨어에서 백라이트 밝기를 조정할 수있었습니다.
이 모니터가 분명히 지원하는 제어 코드는 다음과 같습니다.

또한 몇 가지 다른 도구를 평가했습니다.
- 디머 -백라이트를 어둡게하지 않습니다. 가짜 소프트웨어 디밍을 사용합니다.
- ScreenBright- 백라이트를 제어하기 위해 DDC / CI를 사용하지만 저자의 웹 사이트에서 제거되었습니다. 나는 그 독창적 인 거울 사이트 중 하나에서 다운로드를 시도하지 않았습니다.
- 레드 시프트-디머처럼 가짜.
편집 : Windows에서 화면 밝기를 설정하기 위해 API를 사용하기 쉽다는 것이 밝혀졌습니다. 예제 코드는 다음과 같습니다.
