That 2408 of mine, when it came via freight, had a flyer inside it telling me
that they'd included a new interface, over and above the specs, but I forget if
it was the HDMI or DisplayPort.  I'd never used either before.  Really tiny and
tight interfaces, both, and probably requiring a protocol like ddc2.  There's
actually 8 different switchable interfaces (well, seven really, it's got 2
different DVI's.)  You can bring in broadcast video by either RCA jack, SVideo,
or the component video.
