How to learn the identity of the graphics card?

Yes, we know that it is a perfectly fine entry level GPU capable of 
supporting JavaFX graphics requirements. I shouldn't use the word "bad" 
card. What I'm saying is that you will have to add it to your blacklist 
if you don't want JavaFX to use it for rendering due to poor framerate.
