如何選擇最適用的投影幕?

投影幕的選擇需要考慮多方面因素,哪麼該如何選擇呢?

確定您的安裝方式

如果投影機吊裝,最好買反射式MW銀幕,如果投影機地裝,比如放在茶几或者矮桌上,就最好用回射式銀幕,而漫反射銀幕對於吊裝和地裝兩者都合適。

確定投影畫面比例

視乎平時最常播放的信號格式。也就是說你用投影機主要用途什麼?如果多半用來看DVD/ Blu-ray,現在DVD / Blu-ray90%都是16:9的畫面(雖然2.35:1的也很多,但是包括字幕也要16:9的區域才能完整顯示),那就買16:9的銀幕;如果主要是打遊戲,遊戲支持的分辨率主要還是4:3,那就買4:3的幕。

確定可用的投影尺寸

屏幕的尺寸是指其對角線的長度,對於投影幕尺寸大小的設定要根據安裝空間的大小來決定。正投最佳的觀看位置應該在距離屏幕相當於投影屏幕對角線尺寸1.5倍左右的位置上,距離太近或是屏幕太大都會造成看影片時因為看不過來眼睛要不停轉動,時間長了就會十分疲勞。

計算畫面所需增益

利用公式可以比較準確地計算出自己需要多少增益的幕布,該公式為:當前白牆的增益1 / 當前的畫面面積=期望的銀幕增益/ 期望的畫面面積。
