Can i swap diff-pair on it? Example: TMDS_D0 to TMDS_D2 and DP++0 to DP++2 simultaneosly.
And can i swap tracks (p/n) of diff-pair?

    Hi Ivan,

    Yes you can swap lanes and polarity as long as lane and polarity from GPU are matched to HDMI connector.
    Better keep TMDS_CLK in its intended lane position, just swap data lanes.
    Refer to datasheet pins function table for infromation about how DP++ lane convert into TMDS lanes.

    Regards
