I have a 1.67ghz powerbook with the 128mb video card in it. I just hooked up a 20" WS Dell 2005FPW to it. I had it on 1600x1000 and found the text to be of adequate size. It was not super sharp though. I changed it to 1680x1050, same ratio but the text is slightly smaller and thinner. It is much sharper though. Is 1680x1050 just a better res for this powerbook, or do I have a bum monitor?
