Re: Mac to VGA Adapter Question

["Bryan Parkoff" <BParkoff@satx.rr.com>]

    My monitor is Sony Multiscan W900.  It does have NTSC switch.  I believe
that it supports least 30.0KHz.  I don't know if it has 15KHz.  Now, you
mentioned that there is rare adapter that allows to cause Sony Multiscan
W900 to accept 15KHz using Sony's NTSC switch.  Please advise.
