開啟電源時顯示器沒有影像

連接至下列 OptiPlex 系統主機板的 DisplayPort (DP) Dell 顯示器可能不會顯示影像。在系統啟動後開啟顯示器，便會發生這種情況。


受影響的 OptiPlex 電腦：

  • OptiPlex 3050
  • OptiPlex 5050
  • OptiPlex 7050
  • OptiPlex 3060
  • OptiPlex 5060
  • OptiPlex 7060
  • OptiPlex 3070
  • OptiPlex 5070
  • OptiPlex 7070

Cause

此為設計運作方式。整合可延伸韌體介面 (UEFI) 圖形輸出通訊協定 (GOP) 需要顯示器先取得延伸顯示識別資料 (EDID) 資料。收到數據后，它會將視頻輸出到監視器。

Resolution

此為熱插拔偵測設計遵循 UEFI GOP 和 DP 標準下所期望的行為。

此行為的因應措施是先開啟顯示器電源，然後再開啟系統，以確保能夠偵測到顯示器。
