Did you find somewhere some documentation that suggested to you that this *should* work?   X resources don't work that way...

I think maybe you meant this:

 `fullscreen' (class `Fullscreen')
     The desired fullscreen size.  The value can be one of `fullboth',
     `maximized', `fullwidth' or `fullheight', which correspond to the
     command-line options `-fs', `-mm', `-fw', and `-fh' (*note Window
     Size X::).

     Note that this applies to the initial frame only.

Which is the fullscreen resource, not a value for the geometry resource.   For example:

  Emacs.fullscreen: fullheight
