    NOTE:
    • 1080i@25hz and 720p@50hz will run in 100 Hz; other 3D timing will run in 120 Hz.
    • 1080P@24hz will run 144Hz (XGA, WXGA, 1080p)/96Hz (WUXGA).
    • If the input frame rate is 48 Hz or greater, the output frame rate is set to twice the input frame rate (FRC = 2X mode).
    • If the 3D input frame rate is 25Hz or greater, the output frame rate is set to four times the input frame rate (FRC = 4X mode).
    • If the 3D input frame rate is 24Hz (includes 23.9Hz), the output frame rate is set to six times the input frame rate (FRC = 6X mode).
