    Hi Jerry,

    Sorry for the late response

    Local I2C interface needs 4.7k pull-ups to 3.3V, are those resistors close to I2C master?

    D you need HPD polarity inverted?

    Why there are EEPROMs on input ports instead of having just one at output port?

    LC_A0 is missing the pulldown

    I guess by I2C you are disabling 5V_EN

    Why are you not using 5V_PWR, HPD, DDC pins of TMDS442?

    Regards
