my screen is absolutely perfect, best notebook screen I have ever had
fast (8ms ?), bright with hich contrast, very large viewing angle ( I'd guess 170°x170° )
It's even better than an expensive 19inch TFT I recently bought.
I think by "leakage" you mean an overly bright bottom frame? I don't have that...
Asus in Germany has a very good costumer service, phone them and tell them your problem. The number is in the garantie booklet. Asus offers a 30 day single pixel garantie, if you have a bad or dead pixel in the first 30 days you can have your notebook exchanged.
