Logo selection for poster presentation I am presenting a poster at ICBC, which is sponsored by the IEEE Communications Society (ComSoc).
I am planning to use two logos for my poster.
I am considering the logos of the following:

The research organization. The presented research is from researchers of this organisation.

ICBC, the conference organizer

IEEE Communications Society (ComSoc), the conference sponsor

Logo of ICBC and IEEE, indicating both organizer and sponsor.
Which two logos are suitable for the poster presentation.
The logos on your poster should indicate the author's affiliation.  Use the logo of the presenting author's university.

Never use the organizer, sponsor, or host logo unless you work for them.  People attending the conference already know what conference they are at.  This information is not needed on a poster.
