If a code was created as a Display Creative code, the media type cannot be changed because these codes are charged at a different rate than the other media types. For this same reason, you also cannot change a code that was created for another media type (such as Video) to Display Creative.


Since HD and 3D are only valid for Video codes, an HD or 3D code cannot be changed to another media type. Also, if an SD code has a matching HD or 3D created, the media type cannot be changed.
