Depends on the monitors but nearly every graphics card available can do that now.
Do you have multiple outputs on your current graphics card?
What... 2 2420HD's?Ive got hdmi and vga....
Im thinking of running benq 2420hd

They have DVI and HDMI and VGA inputs. I'd get an Nvidia graphics card that has a DVI and HDMI output (don't like ATI - I've had problems with every one I've had). Ebuyer has a passive 610 for £25: http://www.ebuyer.com/507106-evga-nvidia-gt-610-passive-810mhz-1000mhz-1024mb-64-bit-ddr3-vga-hdmi-01g-p3-2613-kr
Dell Ultrasharp (they have product numbers like Uxxxx) are generally considered the best bang for buck (at least I hope so - I have 3 here!).BIm open to screen suggestions aswell![]()
Difference between LCD and LED?
As Neils says..Difference between LCD and LED?

GT 640 will do triple screens (and comes in passive formMost cards if they have two ports will support dual screen, if you want triple screen you need to research it a bit more as its not as straight forwards as you would think.
Hmm.. I'm not a fan of using a TV as a display. Firstly, the pixel pitch is way too big (that 40" screen probably has fewer pixels than the 24" screens beside them), plus unless you know what you are doing, there's a good chance your screen is set for TV colour space rather than PC colour space.I currently us a 40inch Bravia as my mans screen and two dell 24 inch monitors in portrait on either side.
No. It is important to use digital interconnection (DVI/HDMI/DP/TB) over analogue (VGA). Assuming the bandwidth is high enough, each of the digital interconnection methods are equivalent.it is important to use identical connection types as lets say your card has a VGA port and DVI, there will be a huge difference in screen quality.

But you don't say what the Dells are, so no idea if they are good or bad... plus just because the screen is calibrated doesn't mean it is responding correctly to 0-255. TV space is 16-235 in each channel...The TV is calibrated and has a far better image than the Dells, but then they are around 8 years old now
Yup the Dells are higher resolution (1920x1200 vs 1920x1080). Viewing a 40" screen at that distance and that resolution you should be able to see the individual pixels...it is 1080p screen the monitors are 1920 x 1200
