Lots of newer big monitors have controls for keystone, pincushion, etc.
Try degaussing it.
If you still don't like it, try to take it back.
I like my Hitachi 771 - [link|http://www.newegg.com/app/ViewProduct.asp?submit=manufactory&catalog=19&manufactory=1095|here] is an assortment of Hitachis at NewEgg.
Best of luck.
Cheers,
Scott.
