I bought a sony 51", gonna be here tommorrow, very eager and asking alot of questions AND learning alot here reading through threads... I'mma be very eager to play my xbox on it (given i have the cables by tommorrow), AND i know the bestbuy delivery guys arent gonna do jack shit but plug it up and turn it on and off. Ive been reading through threads here and my safe option once recieving IS turning down the contrast and brightness a little. WE ALL Know this and is stressed throughtout the forums.. But my question is.. How long should i go with this "preliminary calibration" before finally calibrating with AVIA?? Im sure to recieve a copy of avia within the next week or so, im just hopin thats not too long.
