DVI digital signal over VGA cable

[Beth]

Does anyone know of an adapter that will allow me to run a DVI-D signal
through a VGA cable
(turn a VGA cable into a DVI-D cable)?

Problem is that my computer has a DVI output, and my flat-screen TV in
another room has a DVI input (digital only) but the only wire running
through the walls is a VGA cable.

When I google it I am only finding results for adapters to go from DVI to
VGA.

I did try a standard DVI to VGA adapter on both ends and it didn't work. I
think it is only passing the analog part of the signal so there is nothing
to "convert back" at the digital end.

Thanks

No. Doesn't exist; DVI requires multiple shielded paired conductors,
and VGA has three shielded single conductors; the 'adapter' is just
a way to use the VGA signals kept (for compatibility) off to
one side of some (not all) DVI sources.

Thanks for your reply.
Looking at this site (http://www.vellone.com/support/dvi/) it appears that
DVI single link only used 12 pins.
Cant the 15pin VGA cable be adapted to work for this?

The short, simple answer is no.

I could give you a much longer, less simple answer, but the final word would
still be "no."
