VGA to DVI?

I have a nearly new XP machine. I also have a new Win7 machine. I
continually work on other computers for our computer club.

I have bought a 4 port KVM switch with DVI in and out. My XP machine
(although it has a DVI connection on the back of the video card) won't
connect. I have now added a DVI to VGA connector at the XP machine. Still
won't recognize the monitor. The Win7 machine has no problem with it.

Thoughts? Thanks

Unless the specs or instructions for the graphics card in your XP machine
specifically state that can output either DVI using a DVI cable or VGA using
a DVI to VGA connector(dongle) the odds are that it does not.

GeForce 8500 GT, I see nothing on the NVIDIA site that explains...

I have a 8500GT card and there is no dongle for it to connect to VGA using a
DVI-VGA adapter. My card came with a 7Pin round mini pin connection and a
dongle for it that supports a component or S-video connection. My card also
has a standard VGA connection. Each manufacturer of 8500GT cards can have
different output connections and connection options. So the specific make
of your 8500GT card is important to know its abilities.

Curious, just an update. I have been to the Iogear web site. I found one bit
of information. The connector should be a DVI-I to VGA. I have chased all
over town and the only connector that mentions DVI-I is a Radio Shack item
that reads "DVI-A Female to HDD/VGA Male Adapter." It didn't work. On the
back is a note that reads: "Note: This adapter works with DVI-A (analog) and
DVI-I (digital and analog integrate) cables. It does not work with DVI-D
(digital) cables."

All DVI to VGA or DVI to Component adapters are DVI-I to XXX adapters since
they are using the 4 analog pins on a graphics card DVI-I( the I stands for
integrated digital and analog support capable) connector to provide the VGA
or Component content. If your graphics card and drivers do not support the
output of VGA using the 4 analog pins then the adapter can not do anything
since there is no analog signal available to connect to.
Cables are not an issue since you are trying to use an adapter an not a
cable.

When attached directly to a Samsung flat panel monitor (its mate for two
years) it functions flawlessly, using VGA cable.

I am now confused I am not sure what works and what does not work.
When you say when attached directly to a Samsung Flat Panel Monitor "It"
functions I am not sure what "it: is.
Is "it" a direct VGA connection from a 15 pin Din connector on the graphics
card to the monitor. Or is it a DVI_I to VGA adapter to a VGA cable to the
monitor?

15 pin VGA cable to a 15 pin VGA "socket" port on the monitor is an
Analog VGA cable.

I know what the cables are, and the sockets. I have returned the KVM switch
and ordered this:
http://www.buy.com/prod/startech-com...207534815.html
It should arrive in a couple of days.

I hope it works for you. I reviewed the specs and understood them to mean
that the unit could switch either DVI or VGA. I saw nothing in the specs to
imply that the unit would convert DVI to VGA.
