Hello! I've been using Roell's X386 1.1 for a while with an ET3000- equipped VGA-controller (EIZO MDB-10, I think) and a multi- syncin' monitor. Everything just works great! Now I've got my hands upon a 19" monitor which is said to be 8514A-compatible but I've got no data sheet for it. Somewhere I got the impression that it should sync on 31.5 and 35.5 kHz but that's just a rumour. Anyway I can get it to sync vertically at 60 Hz, but horizontally it's just plain impossible to get anything but a very skewed screen looking something like this: ..\..... ....\... ......\. \....... ..\..... ....\... Where the dots are the ordinary X default background stipple and the backslashes are what I suppose horizontal syncpulses. I've tried to vary the Horizontal sync configuration experimentally, with no luck. I suppose this is what's called a Fixed frequency monitor and from the Tutorial on X386 configuration I understand that it's a completely different matter to configure the chip for such a monitor than for a multisyncing one. Do anyone outthere have an idea how I should attack this problem? I've got no problem understanding the multisyncing configuration tutorial, but the math presented there just doesn't seem to apply to my new monitor.
