I just bought NEC AccuSync LCD91vm and it do not work in 15KHz with Falcon.
I bought it since numerous people praise NEC AccuSync LCD71vm on Amiga but it seems that his bigger brother does not work in 15KHz
On other hand, NEC MultiSync LCD1970nx does work, and it have great picture (PVA ili PVM panel!) but on Amiga it will not display bottom 14 lines (or something like that) in certain resolutions.
NEC MultiSync LCD1400M does not in 15KHz...
and we should definitively have wiki for such topic.
Hope that mpattonm will compile all data in first post but it would be easy if everyone could edit and maintain this database...
