We want to if we can set up to two video cards to run a 35" Tv on a SVGA signal with a 25' cable & a 21" LaCie monitor @ 800x600 or greater resolution at the same time!

I've done this with two ATI cards and two computer monitors... there are a couple of things to keep in mind...

Do you want both monitors do display the same thing, like in a training/demonstration environment? If so, you only need one video card that is capable of TV output. You drive both monitors off the same card, just like using a DLP projector for a powerpoint presentation...

If you're looking to display two different images, say for example you have a DVD-ROM and you want to run that signal thru a TV while still using the PC, then you'll need the two cards. There are some limitations:

The primary display adapter must be the FIRST _video_ card on the bus. This means, (I'll use an ATX forma factor board as an example here) Your primary video adapter would be the one closest to the ATX connector set. You can save yourself the frustrating hours I spent troubleshooting THAT one. :)
(Caveat) I have only done this with cards of the same bus type, PCI/PCI. I can't guarantee what would happen otherwise.

Following that, you can have cards between the two video adapters, but I prefer to put them next to one another. Experiment with slot placement if you get interference or have trouble otherwise.

Windows 98 Multiple Display support basically stretches your desktop so that it's two monitors wide. However, if one of your cards has a TV-Tuner built in and you want to display that signal you can only display it on the monitor it's attached to. (If card 2 puts out a TVDisplay, it's only going to show it on Monitor 2). Everything else behaves as if it's one desktop.

One more thing: Your video card may have limitations regarding the resolution of the TV signal it can output, mine (ATI All-in-Wonder Pro) is limited to 1024x768, although it can go to 1280x1024 on a computer monitor.

Good luck,
Tim

There are other factors you may have trouble with but they're out of the scope of such a short post length. If this does not get you where you need to be email me and we'll go into greater detail.

Well Timp pretty well covered the answer of if you can do it along with some detailed steps of one way to do it so I wil just add some additional notes.

It kind of depends on what your want to output as to the number, type and capability of card that you select. If it is heavy 3D graphics then ATI or NVIDIA are the current leaders in this arena.

The basic background of doing this setup can be seen in Microsoft Knowledgebase Articles Q182708 and Q179602.

A quick overview with considerations can be found at

A good overview of howto and various card comparisons can be found at www.tomshardware.com/graphic

I have had the best business application success using Matrox cards with the twin head design - they really kind of started the two monitor card thing. Info at:
Matrox - www.matrox.com and
http://www6.tomshardware.com/graphic/00q4/001208/index.htm
I prefer the single card approach as it has worked well over a long period.

ATI and Nvidia are great cards with lots of power and I am looking at their new twin view feature that keeps the number of cards to one.

One last note is that you don't want to go cheap- you want a strong card with goodly amounts of onboard memory and you don't want to put it on a dog computer. If your going to do it then make sure to do it right.

Hope this helps

ps all links were good at time of writting but may have word wrap problems due to form posting - take out any spaces %20 if you get error.
