I will not buy ADI, because I don't believe that brand. I do not see the monitor of IBM in Hong Kong. So, I can't buy it. The quality of ViewSonic is not as good as the past. And I think Philips 107P is quite good.
Because 107P support 'Lightframe'.
You can choose it. Or buy a 15" LCD. In Hong Kong, Proview 15" LCD only $3500 NT$14350.
I hope that You can choose a good monitor and remember to tell me what is your decision.
