Well, there is a "USB Monitor Control Class" defined, so you can
connect a monitor which supports this to a USB port and control its
settings via USB, using a tool like hidmin.  This works at least with
Eizo monitors.  I don't what other vendors support this. It's a cool
feature. You can adjust display parameters automatically depending what
out are doing (normal tasks, watching a movie etc.).
