In DL <dl@spoofmail> had this to say:
My reply is at the bottom of your sent message:
This is a common problem, for which there is no simple solution. -
Some work some don't - Often better to use a card that supports dual
monitors.
The answer from DL was rather vague BUT also very accurate and in my travels
I've never come across an authoritative list of graphics cards that are PCI
running in tandem. I'm under the impression of the two following things
however but no amount of searching (perhaps it's my terms used) has shown me
proof of this so take this as a grain of salt.
First, they should be different brands. Using two similar cards in there
causes problems. One from ATI and one from nVidia for instance.
Second, if possible put one in an AGP port and one in a PCI slot has better
effects and is more likely to be compatible or at least more likely to be
capable of running in tandem.
The advice given by DL to simply get a card that will support dual monitors
is truly the best solution but not always financially viable for some of the
less financially able people or for people who are unwilling to invest in
new hardware for various reasons. (Often because when they paid for the PC
they felt that they paid enough so that it should last them for a while
without needing to spend additional money and that's justification enough
for some people.) An old but sneaky trick is to buy a used pickup truck.
(I'm not kidding. I have a friend of mine who does this yearly with great
success.) Then when the day comes for people to move out of your local
community college to head there and simply wait on the corner and watch.
People, particularly college students who's education is being funded by
their parents, are quite likely to be tossing all sorts of hardware out and
much of it new enough to still be of use. Offering to help some poor soul
moving out assistance with their heavy stuff is likely to net you some
benefits.
