Hi everyone. Hopefully I posted this in the right forum. I'm in the market for an external monitor as I am doing graphic design at uni and need a bigger screen than my 13" macbook aluminum's. I was thinking 20-22" (suggest if you think otherwise!). Two I have singled out are the Dell SP2009W 20" and the Dell S2209W 21.5". Can anyone tell me which is the better of the two? They are both the same price. I don't really want to spend much more than that and I'm not fussed on this whole TN vs ISP thing. Please help!!
