Monitor

OK, Let me try again.  I have a monitor made by a company which no longer seems to be around.  It's an IOComm SVGA monitor.  But I can't run it at anything better than 400x600 resolution.  This is perplexing.  It is a better monitor than that. . . and considering that I was able to do better in Windows 3.1 with a Trident card, I would hope that I could do better with my S3 Trio64V+ card that I have now.  And the standard windows SVGA driver doesn't work.  At all. All I get with that is a bunch of horizontal lines.  Help me please.  Is there somewhere that either makes custom drivers, or a way to get a user defined driver?  I do have the spectulations on the monitor and they may be found in my previous question if you really want them.  Thanks
