❖ Note that if you attach video sources to DVI-I connectors 3/7 and 4/8, they
don’t have to be of the same type.
- To attach only a DVI-D video source to DVI-I connector(s) 3/7 and/or 4/8,
you can use a standard DVI cable.
- To attach more than one video source to DVI-I connector(s) 3/7 and/or 4/8,
you must use a custom cable. See Appendix B: Technical information for
information on the DVI-I pin assignment to build a custom cable.
❖ Note that although you can attach more than one video source to Matrox
Orion HD, you can only grab from two video sources at a time.
