dualhead graphic card...

[Wahookah]

right now i have a matrox millenium g400 max. it?s dualdisplay was pretty good for my needs, but it?s rather old, so i?m looking for a good performing dualhead card.

it mainly should be used for 2d, and 3d graphics, some video work [no gaming...] and for some vj-events..
it should be possible to assign an area as source for output over the second monitor cable...

i have an adapter cable from the matrox card which converts monitor out to video- and super video out. can i use that cable for every monitor out, or is it only supportet by the millenium g400 max card?

is a dualhead a good solution, or does the dualhead slow down the graphics card too much?
what about using 2 cards seperately? do i have to use 2 quality cards, or would it be enough to use one high performing card and a cheap one for the output [or vice versa?]

there are some cards offering a dualhead + video in / out, are these good, because it seems to much for one card for me...

i?m happy for every piece of advice you could give me :)
thnx

I'm pretty sure you will find that the actual video card does the VGA to s-video conversion and then just pumps it out over certain wires through the cable.... so the cable deson't technically convert it, the card does so it won't work with other cards (unless they have the same setup). To convert VGA to video off the graphix card you need a scan convertor

using 2 graphics cards is the way forward in the absence of fast dualhead cards - having a cheap pci card and a fast agp card is the way most people seem to favor

i've built 2 machines to run an installation recently that have geforce3 graphics cards in the agp slot and a cheep 8meg sis pci cards that work just fine for the controls

yep, two cards is defiantly a good option, I'm runing a simerler set up as sleepy, gf3 and a 4mg matrox pci card with resolume and it works a treet :)
