It's time to upgrade my 3 17" LCD monitors to the newer 20"-12" monitors. I've noticed that there are mainly two variations on native resolutions at this size. I am interested in swiveling the monitors to be horizontal (tall). My question is which resolution is better for trading? Is there a noticeable difference? I figure more is better, 1600x1200 right? Just wondering why they would offer the strange 1680x1050 rez? Also, does anyone have any experience with the Samsung 204B? It seems to be much cheaper than the Samsung 214T but with similar specs. I've had a Benq, Sony, and Samung. I'm leaning towards the Samsung since the text and lines are razor sharp. I'm just real sensitive to having a sharp as hell possible screen. Thanks in advance for any input!
