How can I optimize my display on my dv 9000?

[Tazz]

Hello and yes before I bore you to tears or worse... I am obviously very new to IP.Board, but it appears that I might be able to get some help from here, cause I learned over the last few days that nVidia is not due to the fact that this is a notebook.

I have a HP dv 9000 HP notebook that utilizes a nVidia GE Force 8400M GS w/128mb dedicated RAM.

So the reason that I am asking for assistance is that although the wide screen display appears nice for general viewing, it becomes not as detailed or vivid when going into any games or even with certain media.

I opened the the nVidia Display panel and have adjusted both the brightness and contrast with mediocre results. I then learned from another web site that the, "Digital Vibrance" control can be adjusted to optimize the appearance greatly, but apparently only with 3rd party drivers.

My Digital Vibrance slider is not active, but apparently some posts lead me to believe that this can be modified to work.

I am not very familiar with this process and would like to know HOW to do this and what risks, if any am I taking replacing a video card driver with a 3rd party one on a brand new notebook. Like will I void my warranty? How hard is this to do, etc?

Several persons seem to have done similar adjustments and had good results. I am being hopeful.
