I asked a kind of simple question recently and it was closed as "too broad". http://superuser.com/questions/1048177/virtualization-assign-graphics-card-to-vm-and-back-to-host-when-the-vm-exits 

But I'm having trouble understanding why/how is it "too broad". I'd say you could legitimately answer the question with a simple "yes" or "no". I mean, sure, some hints on how it could be achieved would be nice, but I don't see how the question would be "too broad".

So how do I get more details for why the question is "too broad"?
