How to show a slideshow on a projector
I've found an answer to this question but it was from 2007 so might not be correct.
My wife made a slideshow using iPhoto '11 on a MacBook Pro with a Thunderbolt and FW 800, Ethernet, and USB ports. The show contains 93 slides and takes 2:46, She would to play it only once on this projector and would like to avoid buying the latest Thunderbolt/Mini-display to DVI or VGA adapter. So far, we've been unable to find out what connections are on the projector. We have AppleTV and already own the following adapters and cables:
Adapters
Mini- DVI to VGA
Mini-DVI to DVI
Mini-Something (old) to S-Video & Composite
VGA (female) to DVI (male, but does not plug into the above Mini-DVI to DVI as the male end has 4 extra pins surrounding the blade)
FW 800 (male) to FW 400 (female)
Cables
Firewire 400 & 800, USB, DVI, VGA & HDMI ( all male to male)
I also exported the slideshow to a M4V movie. Clicking info on Large (864x540) estimated 4 Mbps & 104 MB. Actual file is 113 MB, close enough. Clicking info on Display estimated 7 Mbps & 182 MB. Actual is a whopping 939 MB! Not sure what this is about.
One option is we have access to a Windows 7 PC that's connected to the projector but can't access it beforehand to test it. Would the PC play the M4V format? If not, which format should I use for export?
If the projector has USB input, would transfer be fast enough to just play the movie from a flash drive?
If the projector has HDMI input AND I find my FW 800 to HDMI Cable, can I play the slideshow using the MacBook Pro's FW 800 port?
Finally, based on the 2007 answer, it sounds like I need to modify the display settings in Preferences depending on which port is used. Does that apply to the 2011 MacBook Pro too?
