conditional format to flag the duplicate using wildcard

Let say i want to check column D to see if there's duplicates.

I normally use this formula (in conditional formatting) to color the cell if there's multiple same value ( exact same value) :

=countif($D$1:$D,$D1)>1

But now i want to check if there's the similarity in first 3 letters, For example i want this to be warned as duplicates error.

HowHowyHows

I tried to use wildcards , it works on cell but not working when i use in conditional formatting.

=countif($D$1:$D ; left($D1,3) & "*")>1

Does anyone have a solution ?
