Questions about screen quality

Hi guys,
I'm new to this forum and also to owning a laptop.

This last weekend I bought a HP model dv1540us and noticed while in the store (a local Fry's) that most of the HP screens look similar except for one. It was a dv8110us (I think this was the model). The difference in color depth and contrast was amazing on this 17" screen. I made the mistake of asking a sales rep at Fry's about the screens, which was basically a waste of time and provided zero answers to my questions.

What I asked was if there were adjustments that could be made on the other screens to improve their contrast and or color. No one could help me with this or answer my questions to my satisfaction. As a matter of fact they were all pushing the Fujitsu machines (must have a larger commission).

The way I tested the screens was to set all the screens to a black desktop and then noticed how much darker the 17" screen is compared to the others.
The smaller screens appeared to be a very dark grey and depending on what angle you were looking at the screen the color varied.

The technology is supposed to be similar so what makes that 17" screen so nice compared to the other smaller screens.

I tried to limit the size of my laptop but might be willing to exchange for the larger machine if there is nothing I can do about my laptop regarding the screen quality.

Thanks in advance,
Bob

Thanks for the reply and I am aware of the calibrators that could be used to tweak my display but I am referring to the obvious difference of most of the other smaller displays by HP and that one particular 8000 series model by HP.

I would assume this color variation I see is an uneven backlight condition. I have read some other posts that referr to "light leak" or something like that. Is this the correct term and condition that I am seeing on my display?

Thank you, that would have been my next question, how long will it run with the larger and brighter display on batteries.

I am seeing about 3 plus hours on the dv1540us but I have not done a real good test, just a casual observance while running.
