All I can say is that I purchased a DV7T series laptop from HP with the 40% off CB promo and it has the worst screen I have ever seen in my life. It's the 1440x900 screen and the viewing angles are so poor that even when sitting directly eye level with the screen it is totally washed out. If I go a little bit off-axis the screen results in a negative image. I was using the default settings. Unfortunately I didn't read reviews before i purchased.
