Weird Cable GuyAny of us folks who already had a 1438 monitor when
upgrading to a PicassoIV has to use one of these cables.
Since the PIV uses a VGA connector, the 1438 doubles
as a PC monitor just fine with the adapter cable.
Just to stick to 640x480 or 800x600 (I wouldn't go
any larger) at the standard 60hz refresh rate.
Might handle higher, but haven't tried it.
