I'm doing a presentation in Keynote in 1024x768 resolution but I need it to display in a TV that only goes up to 480p, the setup there is a PC with a VGA Box or something to that effect (I think) to a TV and it mirrors everything on the monitor (and I think the monitor is running at 1024x768), now I can't use that PC for obvious reasons so I will be bringing my MBP to hook up instead, will the mirroring thing work the same? Should I resize my presentation? Is there any problems I should be prepared to face or anything I'll need to configure beforehand?
