[doppletwo]

Another topic was getting slightly off-topic toward this, but now it make me wonder.



What differences can be seen between DVI and VGA?



Is it really must have?



I thought at this pooint with the planned DRM HDMI is the one that is really the must have, if you want a monitor that is going to be fully functional in five years or so.

VGA and DVI-A are analog RGB

DVI-D is a digital RGB connection
http://en.wikipedia.org/wiki/DVI

DVI-I is both and has both DVI-A and DVI-D pins

HDMI includes DVI-D + Audio + control + HDCP

HDCP is the ecryption schem that will be necessary to view protected content.

What questions do you have?

PS: Nothing you buy in a computer display card today includes working HDCP. The first ATI card was recently announced.
