故障診斷

無電力

請確認電源按鈕(或開關)是否已接通。

請確認交流電源線牢靠地連接到顯示器背部和電源插座。

請先將另一臺電器裝置(例如收音機等)插接至電源插座,以驗證插座供電正 常。

電源已接通,但沒有屏幕圖像

請確認顯示器提供的視頻電纜,牢靠地接到於計算機背面的視頻輸出端口。如果 視頻電纜的另一端沒有和顯示器牢靠地連接,請將其牢靠地連接到顯示器。

調整亮度和對比度。

驗證圖形顯示和顯示器之間,是否需要視頻轉接器(如果您使用比 G3 舊的 Macintosh 計算機,則需要 Macintosh 轉接器)才能獲得正常的訊號。

閃爍

電源供應不足。請將顯示器連接到其他電源插座。如果使用了電源保護器,請減

少插接設備的數量。

從主菜單中選擇 ViewMeter 以驗證垂直掃描頻率為 85 Hz 以上。請參閱第 11 頁上 的「規格」。

請移開顯示器周圍所有會產生磁場的設備,如收音機、電源保護器、非屏蔽式揚 聲器、螢光燈、交流變壓器和台式風扇等。

請確認計算機中的圖形顯示卡可以在所需要的頻率下使用逐行掃描模式。要使您 的圖形顯示卡支持更高的垂直掃描頻率,請試著選擇更少顏色或執行更低的分辨 率。

色彩錯誤或異常

如果有任何顏色(紅色、綠色或藍色)缺失,請檢查視頻電纜以確認其連接牢

靠。電纜接頭中的插針若是鬆動或斷裂,可能會導致不艮連接。 請將此顯示器連接到另一台計算機。

Main Menu(主菜單)中選擇 Degauss(消磁)。此操作只能執行一次。 請如果您使用舊圖形顯示卡,請與 ViewSonic "客戶支持"聯繫。

整個屏幕圖像垂直轉動

請認定視頻輸入信號在顯示器指定的頻率範圍內。

使用其他電源、圖形顯示卡或計算機系統來檢驗此顯示器。 將牢靠連接視頻電纜。

控制按鈕無作用

請一次只按一個按鈕。
