I have a 20" Sun/Sony GDM20E20 monitor I'm trying to get rid of. This is
not your average PC monitor. It is a very-high-end graphics display. I
have an adapter to use it with a PC.

Caveats: The last time I used it, it had some "issues". It seemed like
there may be a loose connection inside. Also, it weighs 49lbs. I
currently have it in my car and will drive it to any building on campus.
