Tool/software:

Hi TI,
I have a question about the refreash rate of DLP6750Q1EVM.
As you may know, it is limited 30Hz in HDMI.
I would like to know why it's limited 30Hz.
Could you explain the technical reason and the back ground?


Best Regards,

    Hi Hide-san,

    Nice to talk again.

    The reason this is limited to that is because the video receiver, IT6535 (which has NDA restrictions for datasheet from ITE), only supports up to HDMI 1.4a standard.

    The simple answer is that HDMI 1.4a only works up to 30 Hz for this resolution, and it is outside the scope I am able to talk about. You may, however, read more into the HDMI 1.4a spec if you are curious and want to look up more beyond this.

    Regards,
