Are you making reference to DisplayWidth and DisplayHeight, or DisplayWidthMM and DisplayHeightMM? And please explain which X extension supplies your ``virtual screen'' functionality; I daresay the ``screens'' you speak of are not true screens in the X sense, but rather monitors or outputs, wherein the server extension that implements them should be exploited to ascertain their dimensions.
