Yes, you need an adapter that does the job correctly!is anything special needed to make the video work?
A multisync VGA monitor would laugh in your face at your doubt that it could cope with 67Hz, however it will crumble in a zig zagging heap if given 512 x 384 to work with.The LC might support resolutions the monitor does not like. VGA at 640 x 480 uses a refresh rate of 60 Hz while the Apple 640 x 480 mode refreshes at 67 Hz.
The pivot would have to be using a custom driver. The macs normally just read the sense lines at startup.Will the resolution not change on unplugging and plugging monitor plugs with different sense pin settings, like rotating a Radius Pivot does?
The adapter most likely isn't working properly. Try buying one from ebay. Here's one I found: http://cgi.ebay.com/UNIVERSAL-MAC-VGA-Adapter-1-178B-NEW_W0QQitemZ300159125224QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116hi!.. a friend have a problem with his LC, he built a MAC-VGA video adapterbut when the mac start only show this
