Pretty much any video card these days can do that.
I have Dell Vostro 200 desktop PC with Intel Core Duo CPU E8200@ 2.66 GHZ, 2 GB RAM, Vista 32 bit. My cpu has 2 PCI, 1 PCI Express x1 and 1 PCI Express x16 slots.
I wish to connect a 17" Samsung flat screen monitor (1440 x 900) and a 15" Acer flat screen monitor (1366 x 768).
I will use this configuration for normal data processing (word processing, spreadsheets, etc.) i,e, not for gaming.
The two monitors must run independent applications, i.e. word processing on one monitor and spreadsheet on another without compromising on screen resolution.
Can someone suggest video card I require for this.
