DLPC3479: 输入源帧率和图片显示帧率

Part Number: DLPC3479


您好,

       在dlpc3479芯片手册中,我看到7.2 input source这一章节中对输入源帧率的说明是:

       1920 × 1080 over 10-62 Hz,不支持120Hz。如下图所示

但是在8.3.1的外部图形模式中(external pattern mode),又写道:External pattern mode supports 8-bit and 1-bit monochrome or RGB patterns.

且在8-bit 单色模式下,dlpc3479控制器支持120Hz输入帧率。如下图

请问一下,这该怎么理解?

非常感谢
