Dennis,

A little more detail would be nice.  iBook or PowerBook?  What model?

I believe most video projectors can take an S-video cable. Some also take DVI.

The 15" and 17" PowerBooks have an S-video out and a DVI out. Just plug the S-video cable or DVI cable into both the PowerBook and the projector, and the Mac will see the projector right away.

The 12" PowerBooks do not have S-video out, and they use a mini-DVI port. However, they come with a mini-DVI-to-DVI adapter. You can also buy a mini-DVI-to-S-video adapter. My girlfriend has a 12" PowerBook and we use the mini-DVI-to-S-video adapter to play video content from her laptop on our TV all the time. Again, it's plug-and-play.

The iBooks have a mini-VGA out, with an included mini-VGA-to-VGA adapter. You can also get a mini-VGA-to-S-video adapter.

The only common-looking connector
was a USB cable, but plugging that in made no difference.

Can PC laptops send video over USB? I've never heard of that, and wasn't aware that was possible. Probably the USB port was for some other use -- accessing the projector's menu functions, for example.


So, here I am, following this total failure, asking what to do next time,
short of making sure I have a PC with me. Anybody?

If you didn't know which cables to hook up, having a PC with you probably wouldn't have helped matters.


What to do next time? Find out what method of *video* connection the projector uses -- DVI, S-video, etc. -- and make sure you have the right cables and/or adapters for that. This may require buying an adapter cable from the Apple Store, or it may not, depending on what connections the laptop has and what connections the projector uses. Once you make the connection, it's plug-and-play from there. However, hooking up any laptop -- Mac or PC -- via a non-video connection like USB isn't going to do anything.

Hi all,

Please reply off list. This just happens to be the only place I know that
has Mac users.


This morning I was taking part in a panel with a presentation that included
some clips from a DVD. I arrived to find a standard computer video
projector with all the connectors and cables provided by the venue, my DVD
of examples, and another person's fairly new Mac (Christmas present) laptop.


We couldn't get them to work together. The only common-looking connector
was a USB cable, but plugging that in made no difference. The video
projector didn't see any video, and the Mac didn't respond. Rebooting
didn't work. Pressing the little "two screen" function key didn't work
(whether pressing by itself or along with any of the control-style keys).
And the Mac owner just shrugged like it was all supposed to work
automatically.


With 100 people in the room, not a soul had any idea of how to make a Mac
work with a video projector. A Google search during a break only turned up
sites wanting to sell special cables or talking Mac language I don't
understand.


So, here I am, following this total failure, asking what to do next time,
short of making sure I have a PC with me. Anybody?
