Many onboard graphics chipsets support only a single display, so you'll need a dedicated graphics card to run two monitors. This ASUS EAH4350 SILENT/DI/512MD2 has three outputs - DVI, VGA and HDMI. Still, this will let you connect a display without the use of an adaptor. It's also passively cooled, so there's no noisy fan. This is a great choice for those after a new graphics card for any PC, as long as you don't need to play fast-moving 3D action games.
