※ 引述《ScubaSteve (Scuba Steve)》之銘言:
: 請問何謂 RGB Full Range 呢?該如何設定比較恰當呢?
一般液晶電視的 HDMI 採用 Limited Range RGB,以 0~255 範圍
中的 16 代表該原色的最低亮度,235 代表最高亮度。
一般 PC 液晶螢幕的 DVI-D 或 HDMI 多半採用 Full Range RGB,
以 0 代表該原色的最低亮度,255 代表最高亮度。
PS3 預設是採用 Limited Range RGB,所以當連接到 Full Range
RGB 的 PC 液晶螢幕上時,該是黑的地方會不夠黑(16 > 0),該是
白的地方會不夠白(235 < 255),畫面整體的對比會變低。
所以後來 PS3 在 1.80 版系統軟體更新後新增了 Full Range RGB
的設定,開啟後就能在 PC 液晶螢幕上獲得正確的對比。
