Hi Team –

Posting on customer behalf.

Would you expect the device to receive HDMI2.0 on initial power up with default register settings?

Thank you,

Dan

    Hi Dan,

    If TMDS181 is used in I2C mode, the default expected video is HDMI1.4b,
    TMDS181 will monitor data rate and DDC to configure itself, however the user still need to select the correct Tx termination for HDMI2.0.
    When used in GPIO mode, Tx termination can be selected automaticaly by TMDS181.

    Regards
