Do I need dual graphics cards to have a dual display?

I want to get a desktop set up with dual displays for video editing and wanted to know if I need two graphics cards to run such a setup? If not then any advice on what I do need would be gratefully received! Thanks...|||no, You just have to find a card with two ports on it to plug in to monitors. Most of the time you run one VGA plug and one DVI. If you wanna spend the money tow cards will run two monitors but most new cards have to ports to run dual monitors.|||No. Most common graphic cards support dual display.
