what's this 'available monitor list'?  X doesn't have such a list afaik, so this sounds like an issue with sax2...

Sax2 monitor configuration screenshot

This is how looks monitor selection module in sax2.

I do not know where does this module come from - exclusively from opensuse, or from X.org, but I think I saw similar configuration option in another non-opensuse distribution.

I also can see a section in x.org conf, which shows monitor configuration. I suppose monitor list provides default preferred values for listed options for each monitor model. I do not know if this options affect something, but I think I remember that selecting monitor model similar to NEC MultiSync LCD195VXM+ did help to solve some issues with display. 

(provided section is taken from another machine - not from one with NEC monitor connected)

Sounds like a SuSE bug to me.
