Subject: [SI-LIST] How to connect Chassis ground to DGND

I have question about CHGND connection in DVI connector/cable.
There is two kind of shields - one - is shield for data/clock  pair;
second - whole cable shield.
http://en.wikipedia.org/wiki/Digital_Visual_Interface

We had some EMC consultation - was suggested to connect internal pairs
shield to chgnd.
on pcb make polygone chgnd that cover area up to end of dvi connector.
So diff.pairs will run under slot of gnd.separation.

Question is - how should be connected internal shields in DVI
conenctor - to sgnd or to chgnd?
