Hi Kato-san,
If HPD_SNK is unused, HPD_SRC can be left floated, the pull-down can be placed as a placeholder.
Regarding HPD_SNK there are two ways to handle it:
Place the pull-up on HPD_SNK to have the TMDS181 enabled all the time
Don't place the pull-up but disable automatic power down based on HPD_SNK(register 0x09[2]), again you can leave the pull-up as place-holder

Hi Moises-san,
Thank you for your information.
I will suggest our customer to place the pull-up on HPD_SINK such as it can be used in both hardware mode and software mode.
Best regards,
Kato
