It is a single DVI-I physically.

But even identifying it would not change anything with regards to polling
induced rendering stalls, right? 

Thinking again about my proposed solution from #20, then your failure case from
#22. I can see it is a real concern and presumably this setup is not that
uncommon since you worry about it? 

I just don't at the moment see how to fit all these requirements into a generic
solution. :(
