VP930b Viewsonic LCD (HDMI to DVI capable)? (HDCP)? (help please)...

I'm trying to find out if my LCD will be able to take a dvi input from
an HDMI to DVI cable?

I'm not sure if the cable needs to be HDCP certified or if the LCD has
to have that ability? This would be coming from either my Motorola HD
DVR or my Xbox 360 (using hdmi output, converted to dvi with the
cable)...

Anyone have any insight into this.. has anyone tried this and it
worked?

Thanks

Your monitor is 1280x1024 and HD-720p compatible from a resolution perspective.

As for your question, start here:

http://en.wikipedia.org/wiki/HDCP

After going through it, it looks like you could view 720p unless the
flag is set. If the content provider wishes the output to be
encrypted, then only an HDCP enabled display device can view it.
Apparently, at least some content for the next little while, will
not have encryption enabled. Vista is full armed with DRM weapons,
to enforce the requirements. (For an interesting description of Vista
weapons of mass destruction, see this article...)

I didn't see HDCP in your monitor's specs, so the 720p could be
disabled at any time. As soon as a source device emits an encrypted
signal, you monitor cannot view it (nor can mine).

http://en.wikipedia.org/wiki/HD_ready

This is a Viewsonic monitor that has HDCP support. The word HDCP appears
only once in the specs, and is not prominently featured or explained.

The encryption method is intended to be "end to end". That means the image
is only returned to analog form, at a point within the monitor where the
signal cannot be "hijacked and copied" by pirates. You see, everyone is
a pirate at heart - everyone is evil - and they must be watched by all-intrusive
DRM to keep them honest. (/sarcasm)

Thanks for the info..

I guess my LCD doesnt support HDCP, as I tried hooking up the unit to
my Motorola Comcast DVR, the tv image initially appeared, followed by
an HDCP security error screen (blue screen).

So unless there is a magic workaround short of getting a different LCD,
it appears I'm out of luck on that front.

Interesting. So there are already cases that don't work.

Me, I have nothing to against any top poster personal, but I know I don't
like to read the answer before question, and I know I don't want to exchange
message with topper etc.. So, I have been adding toppers to my kill-file for
years.
