I've learned so far that a Gerund can be used in 6 cases: Subject, Object, Subject complement, Object complement, Object of preposition and Object of possessive.
Participles are used as adjectives, such as; falling monkey, burning building, etc. A participle must modify something in the sentence.
In this sentence:
My phone will ring displaying your name
can someone please explain whether displaying is a gerund or a participle? I can neither put it in any of the 6 gerund categories nor can I get how it is modifying anything in the sentence.
