我長期使用底座接電腦螢幕的方式遊玩,
因為電腦螢幕較舊,所以是以HDMI轉VGA的方式連接。
前一陣子發現訊號出問題,螢幕沒有畫面,
但底座拿去接電視有畫面,所以單純用HDMI線連接是有訊號的。
在這個情況下我覺得也許是轉接器出問題,
但我換了兩個轉接器、兩條VGA線一樣還是沒訊號。
當問題感覺無解的時候,玄的來了......
我拿朋友的底座用我原本的方式,同樣的線材,同樣HDMI轉VGA,接同一個電腦螢幕,螢
幕卻成功顯示了!?
所以結論是我的底座單純用HDMI可以輸出訊號,
但是若用HDMI轉VGA卻無法輸出訊號。
而同樣條件只是換了朋友的底座
朋友的底座是可以透過HDMI轉VGA輸出訊號的
超級詭異有人知道可能會是什麼問題嗎?
也有去電展碁
工程師說標準作業流程是會用HDMI接電視測試
如果這個狀況沒問題,就會認定底座是OK的
所以我的狀況也沒辦法拿去維修,因為我用HDMI也能正常顯示
