This question already has an answer here:
A more general form of this question has been answered here for example, but I want to know what makes a good poster presentation in physics and/or engineering conferences.
Obviously the poster must be visually appealing as discussed in various posts here, but I have seen cases where the most stunning posters (looks really good and well-written) did not win poster prizes when judged by professors at the conferences. Can you give reasons as to why this happens? Are there some special conditions or requirements in physics/engineering for such presentations?
