A colleague at work has verified that his Sharp Aquos 37" TV works fine
with his video card DVI output connected to the TV HDMI input via a DVI
to HDMI cable. His computer is running Linux, not Windows. So in this
case, the TV is accepting NON-encrypted digital video correctly as it
should. Hopefully, for non-protected content, Windows will properly NOT
use HDCP. It's only for protected content that it is expected to use
HDCP to ensure you cannot use a monitor that is really something like a
recorder, or let you tap the HDMI cable wires (it's encrypted in HDCP).
