From reading past forum posts, it appears that a DVI-D connection, if made over high quality coax cable, can be run up to 9 meters. Nine meters is 4 meters longer than the max length spec'd for DVI-D.


I would just buy a high quality DVI-D extension and give it a shot, except that the connectors will not fit through the opening in my wall.


I need to solder the connectors on after running the cable.


So, I need the following:


1. DVI-D connectors. 1 male. 1 female.


2. 25 ft of High quality coax cable with the proper wire count.


3. The proper pin-outs and preferably a wiring diagram.


Can someone hook me up with a source for these items?


Any additional recommendations?


Thanks.

As DVI-D connections consist of 4 (single channel) or 7 (dual channel) differential pairs methinks COAX would not be the best choice. Perhaps BIAX if it could be found with a 100 ohm differential impeadance? Sounds risky, bulky, and expensive. Let us know how it works :D

Dave -


What?


You are mocking me, or are way beyond me.


I am trying to find out the type of wire/cable to try, and a source. An EE I am not.


But a quick google search for "100 ohm differential impedance" does turn up the things like the following:


"Use two RG- 174 50-ohm coax cables to route a differential, 100- ohm signal into the designated signal pin pair. Let this signal go through the connector to the far side. On the far side, terminate the signal differentially with 100 ohms. "


What that means in relation to DVI connectors, I have no idea, but If the term BIAX is added, there is only one result....


So, what kind of wire is used in DVI cables?
