當屏幕從白屏變為黑屏時，我可以聽到噪音，反之亦然。我能做些什麼來修復它？

動態光圈功能開啟時的聲音，是當內部發動機開啟或關閉，來決定有多少光通過光學系統提升對比度的效果時產生。當開啟投影機，動態光圈將被校準3-15秒，然後會聽到這段時間內發動機運轉的聲音。我們理解有些用戶可能對動態光圈開啟時的聲音比較敏感；因此，我們建議您下載我們的新韌體，可以通過USB A型端口自行升級，進一步降低開機時的聲音，（新固件為動態光圈提供了三級調節，以減少動態光圈開啟時產生的聲音，但如果用戶選擇低級效果，但如果用戶選擇低級效果，也會減低對比度性能。）要下載新韌體，請到我們的網站。如果您在安裝新韌體升級時有任何疑問或問題，請聯繫我們當地的服務中心，我們將非常樂意為您提供幫助。
