Because i do know they can do odd things with the pinouts from a card and allot of graphics vendors make VGA something that can be at least connected and used. so while it is supposed to be A, you can get B and C to work too.

I dug out my spare video card and it has a DVI-I port so I think that I'll try that.

I still don't know enough about this whole area, so if anyone has anything to share, it would be appreciated.

If I understand what I've been reading about the DVI interface, without the 4 pins around the horizontal bar, there's no analog output in the plug--see diagram. The DVI-D ones--which is what I have on one machine--do not have the analog signal.

Quoting: "As well as digital signals, the DVI connector includes pins providing the same analog signals found on a VGA connector, allowing an analog VGA monitor to be connected with a passive plug adapter (or with a converter cable with VGA at one end, and DVI-A or DVI-I at the other). This feature was included in order to make DVI universal, as it allows either type of monitor (analog or digital) to be operated from the same connector.

The DVI connector on a device is therefore given one of three names, depending on which signals it implements:

DVI-D (digital only, both single-link and dual-link)

DVI-A (analog only)

DVI-I (integrated – digital and analog)"

One machine has both DVI-I & VGA ports, the other only the DVI-D,. I'll try to find a spare video card and see if that will help.

I can look and see if i have a spare. 10 bux for that is ridiculous.

I have good news and bad news. The bad news is that I went by Fry's and they
wanted $10 and up for an adapter. The good news is I didn't buy one. I say
good news because I'm now learning a little about DVI & I don't think an
adapter is going to fix the problem. The DVI ports on my new computer are
DVI-D (Dual Link). Since apparently a DVI-D port is digital only, I suspect
that attempting to run that signal through a VGA interface either would
require a non-simple (& non-cheap) adapter or be impossible.

It looks like the KVM box is going back (more bad news) & I buy a more
expensive KVM with DVI ports.

Any advice & comments by someone familiar with video and the DVI interface
will be gratefully accepted.

Thanks,

The simple answer is yes, Most graphics cards come with them now, but
you can probably stop by frys and get one pretty cheap. cant image it
would be more than 5 bux.

I just ordered & received a TRENDnet 2-port USB KVM switch kit. I thought I
was OK on the video because its rated resolution is greater than what I'm
running.

What's the problem? It appears to only have VGA video ports and one of the
computers I be hooking up to it has only DVI. Is there such a thing as a
DVI-to-VGA adapter? Will I have problems using this unit with my computers?

I'm sure that the solution is simple, & I probably should know the answer,
but video is one area I have no expertise in.

Thanks in advance for any advice.
