I'm trying to find out what slide size I should setup in Keynote, for a presentation which will be played on four 60" flat screen TV's for a conference.
Thanks in advance for your precious help!
you should set the slide size to the pixel dimentions of the display you will present on:
Keynote > inspector > document tab > slide size:
Thanks a lot Gary!
It seems 1920*1080 is the resolution of those 60" screens.
