I am considering augmenting my 2 21" dell LCD's with the Dell 30" 3007wfp. I would put it in the middle and then put a 21" on each side in portrait mode. The resolution is 1600x2560 so I think it would match up ok with my older 21" as they are 1200x1600. I assume the pixel pitch would be the same? Anyone using this monitor for trading?
