I see.  It's supposed to work out of the box with Linux, and the
reviews on Amazon indicate that it really does.  So, I guess,
either I got a defective product, or maybe Linux has a way to
work around the bug.

The manual doesn't mention firmware upgrades.  The display shipped
with a lot of accessories, but no software.

I could try connecting it to a Windows machine and see what happens.
