HDTV picture settings forum: Just got Samsung PN51E8000,some questions about calibration

I just purchased this TV the other day and I have been blown away.Every since making the jump to HD six or 7 years ago, I had it in my head that LCD was the only way to go.However after several bad experiences with a variety of brands, I decided to give plasma a go, and I couldn't be happier. I think I really did my research with this make/model. Everything is unbelievably vibrant and natural looking in a way I never even knew was possible.

When I purchased the TV ( From a Future Shop, in Canada) the guy there kind of talked me into getting a calibration, which, if I am correct, would be from a third party that they have an arrangement with.The cost of the calibration is 100 dollars ( supposedly knocked down from 300).

i understand that there is a break in period of around 100 hours and I am probably around the 20 hour mark so far.I have never had a TV calibrated before and I have some questions about the process.I apoligize in advance for the noobish nature of these questions, but I have already asked around on several forums and I haven't gotten a straight answer out of anyone. I thank you in advance for your patience and helpfulness.

1.Will having it calibrated void my warrenty?( I plan on emailing samsung about this, but if you guys could tell me what is generally the case I would apprecieate it.)

2.Will it result in my TV consuming more, or less energy, and will it contribute to my set either lasting longer or shorter?

3. Is there a type of viewing material that would benefit most from calibration? The. ain reason I bought this Tv is for gaming, and I'm wondering would a calibration make sense for gaming? It seems to me that it would be less desirable than it would be for other mediums.

4. Supposing that I go through and get the calibration, and I dislike it, is it possible for me to fully undo the changes that were made?


Again, sorry for such a long post, but I put alot of time and energy into finding the right TV for me, and I don't want to do a calibration without fully understanding the risks.
