LOL. I'm not looking to save a few bucks on a cable, I have a new HDMI cable and I'm just fine in that respect.
My comment was for the original poster, who has a Dwin cable in the ceiling that was wondering if he could repurpose it. Of course it can be cut and terminated. Not that it'll be easy or worth it, but it's just a DVI cable with a proprietary connector on one end. But of course you need to be careful about shielding etc. so you don't have RFI problems.
Or easier and less messy, have an electronics shop make a proprietary round->DVI converter or dongle made from a female instance of the round connector that Dwin uses.
Of course, if pulling a new cable is straightforward, then just pull a new HDMI cable (and use HDMI->DVI adapters if DVI is needed).
