I want to connect a new LG monitor to my iBook (which has a damaged screen. I bought a Dysen (?) adapter ($19/Best Buy) that was supposed to fit a Mac laptop to a VGA connection. However, the Mac end of the adapter doesn't fit the video port in the iBook. (It does fit my newer MacBook). Who makes an adapter to fit an iBook to a VGA cable? Where can I get it (in the USA)? Thanks.
