In that display, did you checkmark the "Show all monitors" option?  That
begin the display of LOTS of monitors and yours may be in it.  Even if
it isn't, if you click on the little ">" symbol next to the "Generic
CRT" or "Generic LCD", it should display more selections.  When you
select one of those monitors, you should get the "OK" button
highlighted.
