[kwlug-disc] Confession (DVI)

Sorry I'm so late for our appointment.  I'll just sit here on the couch.

Okay.  This has been eating me up.  I'll just say it.

I've never successfully used a DVI cable on my computers.  There. It's
out.  The words are laying on the ground like dust.

I'm expecting:
- unplug working video card -> vga cable -> vga monitor input
- connect same video card-> DVI-D cable -> DVI input on same monitor
- video works

What I'm getting:
- unplug working video card -> vga cable -> vga monitor input
- connect same video card -> DVI-D cable -> DVI input on same monitor
- Monitor says, "check video cable" in an accusing manner.

Sure, I've tried.  I don't want to be the Luddite on my block.  I've tried:
- multiple monitors with DVI inputs (HP, two different model numbers)
- multiple video cards with DVI outputs (radeons and an nvidia)

In each case, the cold-eyed "check video cable" is met by the
rage-filled seething cauldron of hate that is my approach to trouble
shooting.  In each case, the video card and monitor even work when
using the DVI output with a little dvi-vga dongle and a vga cable to
the dvi input.  What am I missing?  Must these video cards be tweaked
by a DVI-D driver to output for a DVI-D cable?  Is there a particular
sacrifice required?  Do these cards usually need to change jumper
settings for DVI-D?

pebkac is almost certain.  Go ahead.  Hit me.  Or if you have a
known-good DVI-D cable I can borrow, I'd be all over that, too.
