Free 21" fixed-sync monitor in London

I would think it has to be broken. If the info is correct, Hitachi specified scanning would start at 31 khz (vga) not 35 khz (mac). Mac and pc video is different in that one uses negative going sync (and video?) pulsed, the other positive. Mac video is industry standard it would seem, as so many of these fixed freqs readily work w/macs (found one once that wouldn't, a Sony GDM-can't remember, 48khz. I chalked it up to sync pulse width or something, but don't really know. Maybe it was a weirdo and expected opposite polarities). IBM ps/2 may have been intentionally less compatible? Of course there were 3rd party cards that presumably would plug right up to these monitors (and I still have 2 IBM/Sony GDM-1932s or something, trinitron. I think they may have been intended for AIX equipment, cad/cam for sure though). --- On Fri, 7/1/11, Michael Kerpan <madcrow.maxwell at gmail.com> wrote:
