The story with my new 20" LCD Monitor has not ended....
Now, my LCD monitor is blinking from time to time. This happened more often when I am accessing the network. Happened only when I am using the DVI cable. You just couldn't imagine how annoyed by this I am. I hate the ATI display card. And it appears to be a common problem. Try searching "ATI blinking" and you will see tons of links from all the angry ATI customers.
To save your time, now the solution I found. I think it applies to different ATI display cards.
In ATI Control Catalyst software, on the Attributes screen, enable "Reduce DVI frequency on high-resolution displays". If this doesn't work, try "Alternate DVI operational mode". BTW, I am using 1680 x 1050.
If you put your mouse over the option, you will see the help text to ask you to select them if you have corrupted display.
(Updated 2008-02-17) I tried to update my ATI driver to 9.1 but the same problem happened even after I used the above options. Rollback to the original 8.5 resolves the problem. What a nuisance!
(Updated 2009-06-15) Problem fixed lastly. I replaced my display card with a GeForce GS8400. And I am happy.

Actually disabling "Alternative DVI operational mode" (which was turned on probably by default) solved the issue.
