Samsung Tab S9+ External Display doesn't work (#galaxy tab s9+)

[crj1017]

Hi 

When I try to connect a external monitor to my Samsung Tab S9+ (#galaxy tab s9+) in the displaya message appears on the display stating that the connector cannot be charged due to humidity when it has not been exposed to any humidity.

I put an example: 

Do you know how this can be fixed or anyone has the same problem?

I tested in a Galaxy Tab S8 Ultra and this External Monitor work only when I connect by USB-C without any issue and work in the Galaxy S22 Ultra in the same way without any issue.

Thanks

It also says check for dust or debris. Have you done that?

[crj1017]

Yes Robin I did and did the test in other devices like Tab S8 Ultra and S22 Ultra and work without any issue. Thanks for your answer

Have you tried another cable?

[crj1017]

Yes I did with another cable but with the same result

...does the same message appear when plugging the tablet into a charger or a pc/laptop?

No, only with the external display
