Hi, Thanks for reading my article.

I am facing the problem that hot plug detection of hdmi is not possible.


I have two settop boxes.
One of the settop boxes connected to the hdmi connector, and both the hot plug detection and the DDC were operating normally when the board was turned on.

The other set-top box was connected to the hdmi connector and the hot plug detection and DDC did not work properly when the board was powered on.
DDC communication seems not to be done.
However, when connecting the hdmi connector after turning on the board first, DDC communication is normally done.

Is there any way to look at this part of the problem?
Is there any way to operate the same as connecting the hdmi connector in the middle after turning on the board?
I am always thankful for your help.
Have a nice day!
