回复：俺在用dell的2001FP，很满意，

Thank you very much, old-cotton.

But I heard some negative news about dell 2005 20. LCD, such as dead pixel, leakage (black light). So I do not know whether dell 2001 has such problem.

I find MultiSync LCD2060NX-BK maybe good choice, But I don't know whether it is true. I can not find review about it. (http://shopper.cnet.com/MultiSync_LCD2060NX_BK_Black_20_Digital_Analog_LCD_1600_x_1200_600_1_Contrast/4014-3174_9-30842208.html?tag=pb&rvwtp=4126-3174_9-30842208&orderby=90&sort=)
