The hw is convinced something is attached. Is the physical connector dirty? Does plugging in and removing a real monitor clear the erroneous state? Does Windows work?
About the only brute force you have available is to do a forced hw probe instead of checking the state changed, or to always use the EDID detection (which then breaks those monitors without EDID).
